One of the common complications that occurs with diabetes is brown or red spots that appear on the legs. The nature of such rashes is not related to psoriasis, so many are interested in what such spots actually are.
These complications cause the patient a lot of unpleasant sensations, causing various inconveniences. So what are dark spots on legs, and how to get rid of them?
In diabetes mellitus, metabolic processes are disrupted, which contributes to the subsequent formation of various pathologies in many systems and organs. The skin for this disease is also no exception.
In reality, the factors that cause red spots to form on the legs are obvious. The nature of their appearance lies in severe metabolic disorders in tissues. As a result, various inflammations occur on the surface of the dermis, in the hair follicles and pores.
In addition, diabetics have weakened protective functions of the body, which leads to infection of the epidermis by pathogenic bacteria and microbes.
With the progressive stage of the disease, the patient's skin undergoes multiple changes: it becomes rough, peels and loses elasticity.
Are dark spots on the legs a factor in the development of fungus in diabetes? Fungal infections are often caused by the bacterium Candida Albicans. This microorganism is somewhat reminiscent of yeast, it causes itching, rashes and redness of the epidermis (as shown in the photo).
Basically, the fungus is localized in the wettest and warmest places of the dermis, i.e. it feels great in the folds of the skin.
Problem areas for a diabetic are:
Often, red itchy spots on the legs, concentrated in certain places, are a clear sign indicating diabetes mellitus. And most often the complication is caused by a fungal infection. The fungus almost always concentrates on the feet.
Note! To remove redness, dermatologists recommend applying natural oils that have an antibacterial effect to the affected areas.
Can rashes on the lower extremities be the result of dermatitis and what do you need to know about this complication? Today there are at least thirty varieties of different dermatitis.
Important! In this case, we mean skin diseases that progress as precursors of diabetes or against its background during the development of the disease .
There are 3 categories of the disease. First, it is worth noting the primary skin diseases. Dermatologists include in this category all the symptoms that were caused by various disorders occurring in metabolic processes if the patient has diabetes.
Regarding secondary diseases, this category includes infectious skin diseases caused by bacteria and fungi.
Note! Skin rashes in diabetes develop due to a decrease in general and local reactions of the immune system.
In the third category of dermatological diseases, due to which red spots appear on the legs, dermatologists include characteristic skin diseases. They often appear after using medications used for diabetes.
What do you need to know about diagnosing skin rashes on the lower extremities in diabetics? Patients who come to see a dermatologist with skin rashes of various types are usually referred by the doctor to undergo various tests.
Research also includes an analysis showing the blood sugar ratio. Often, patients who have visited a dermatologist with suspected dermatitis and accompanying inflammation are diagnosed with diabetes.
In other cases, the diagnosis of dermatoses in endocrine diseases is carried out in the same way as in other skin diseases:
To determine the factors causing dermatitis that belong to the secondary group, the doctor prescribes special tests for bacteriological cultures. Thanks to such studies, infectious agents can be detected.
What should people with diabetes know about treatment options if dark spots appear on their legs?
The treatment method for dermatitis is directly related to the group to which the disease belongs. First of all, the doctor selects a treatment aimed at maximizing the restoration of metabolic processes. That is, first of all, the dermatologist treats not the consequences, but the reasons due to which the skin rash has spread.
Diabetic dermatitis belonging to the primary category does not require complex and combination therapy. When the patient's general condition is stabilized, the number of skin rashes will decrease significantly.
For effective and successful treatment of various infectious rashes, special treatment methods are used, which include anti-allergenic drugs.
And in order for dermatoses on the lower extremities to disappear faster, these products must have antifungal and anti-allergenic characteristics.
The success of therapy for dermatoses in diabetes mellitus directly depends on correcting the patient’s general health and normalizing the metabolic processes occurring in his body.
Red spots that accumulate on the legs are quite difficult to cure. To do this, you need to complete a whole course of comprehensive skin care.
Important! If you have various types of dermatitis, you should use only mild, fragrance-free skin care products. The use of moisturizing creams and products with a photo effect is also recommended.
To soften the rough surface of the feet, it is better to use pumice or special files. At the same time, you should not remove the formed corns yourself and use any folk remedies to remove calluses.
Important! A patient who has red spots on the lower extremities should wear clothes made from natural, high-quality fabrics. You should also change your underwear, tights, stockings or socks daily.
In addition, it is necessary that the clothes be selected strictly in size. This condition is extremely important so that the skin can breathe freely and not be squeezed or rubbed. If small and minor inflammations appear, the dermis must be immediately disinfected.
In addition, you cannot seal the wound with a plaster. In the case of the formation of various dermatoses in diabetes, it is necessary to contact a dermatologist as soon as possible, and then visit an endocrinologist.
Despite the fact that with dermatoses that are complicated by the underlying disease, the occurrence of consequences is unlikely, but they can still occur. These include eczema and even gangrene in diabetes mellitus, if the crack or wound has become infected.
The formation of erysipelas is also possible. But the main complication, in which red rashes appear on the lower extremities, is considered to be an exacerbation of all vital processes.
Therefore, a diabetic begins to have difficulty moving, but many patients do not pay due attention to this serious sign, believing that it is a diabetic consequence. From the above we can conclude that diabetic dermatoses may well be accompanied by complications.
To prevent this from happening, the patient must undergo timely diagnosis. After all, diabetes mellitus obliges the patient to constantly monitor the state of his health, not allowing even the slightest indulgence. Only in this case will a diabetic be able to improve his quality of life to a full level.
When faced with a diagnosis of diabetes mellitus, a person must understand the important thing that the development of any complications occurs only with the patient’s connivance. One of the side factors is spots on the legs due to diabetes. What is this connected with? Is it possible to prevent skin manifestations if prevention is carried out?
Regardless of the type of diabetes, a person's process of assimilation of glucose by the body's cells for conversion into energy is disrupted. The problem arises due to the rejection of this product by the cells themselves:
In any case, the excess must be disposed of outside. If the excretory process slows down, glucose turns into fat. Excess sugar can be removed from the body through the kidneys or through the sweat glands. Accordingly, such a violation cannot pass without leaving a trace on the skin.
Some people neglect daily hygiene procedures and even rarely wash their feet. Excreted sweat serves as a beneficial environment for the penetration and development of microbes and bacteria. Their waste products settle in the sweat glands and any wounds on the epidermis. Redness of the legs occurs in diabetes mellitus.
Skin changes in diabetics occur due to the prolonged presence of excess sugar in the blood. The metabolic process of carbohydrates is disrupted. An imbalance in the system begins to affect the condition of the skin.
Among the skin lesions on the legs caused by hyperglycemia, the following types are distinguished:
Small spots of a light brown hue on one or both legs of a diabetic. They have no pain symptoms and do not complicate a person’s life in any way. They remain on the skin for a long time, but can disappear without any specific treatment.
The appearance of such spots can cause alarm due to the unexpectedness.
Some experts explain dermopathy by mechanical injuries that a person could simply not notice. But during experiments (intentional trauma to the skin), similar spots do not appear on the dermis.
Red spots on the legs have a bluish tint. Unlike dermopathy, the size of skin changes is larger. As diabetes progresses, the color of necrobiosis changes from red-blue to yellow. Trophic areas begin to form. The patient may experience pain in the places where the changes appear. Any movement on foot is accompanied by pain or partial numbness. The process is irreversible. Treatment is aimed only at relieving pain and preventing inflammation in exposed areas of the dermis.
Changes in the skin, accompanied by severe itching. Disorders of carbohydrate metabolism affect the nervous system, destroying its cells and leading to a failure in the conduction of neurons. Typically, with this disorder, dark spots appear on the skin of the legs or other areas.
It appears on the skin in red spots and can appear on any part of the body.
Imaginary dirt on the feet and legs is also a sign of diabetic changes. It is impossible to wash off such stains, because these are subcutaneous changes. Pigmentation occurs only in the thickened area of the dermis.
Symptoms indicating a diagnosis of diabetic foot require special attention. The disease is serious. Diabetics are given training in which they talk about prevention, excluding irreversible processes.
Another type of red spots that may appear on the body of a diabetic. An additional sign is a blister containing fluid, similar in appearance to a burn. After normalization of glucose levels, it may disappear without additional therapy. If the bubbles open and dirt gets into them, complications are possible.
In total, there are 30 types of skin changes that appear due to impaired carbohydrate metabolism.
Only a dermatologist can identify spots. In many cases, correct and timely treatment of tumors can be stopped or put into remission.
Complications with diabetes arise when a person does not understand the principles of sugar compensation or does not want to change his usual lifestyle or does not follow a diet. If the patient strives for a long life without diabetic complications, he will follow all the recommendations and monitor his diet.
Skin spots, as a result of excess sugar or insulin, can be called alarming signals from the body. He can no longer cope with sugar toxicity alone. The immune system is unstable and cannot be a barrier to germs and viruses.
Legs always experience a lot of stress. Obesity of the diabetic type increases pressure on the vessels and veins, which in the lower extremities have a narrower lumen by nature.
With diabetes, blood circulation to the legs is reduced, the walls of the vascular system are damaged and clogged with glucose crystals.
Sugar compensation is carried out with the help of drug therapy and adherence to a dietary menu. These are the first actions that a doctor recommends to a diabetic when confirming the diagnosis. All prescriptions must be carried out systematically under the supervision of an endocrinologist and nutritionist. Skin changes on the legs require the participation of a dermatologist.
Prevention can prevent complications that often accompany sweet illness. It is necessary to follow a number of rules that are the norm even for a healthy person:
Not all diabetic skin spots appear after the disease is diagnosed. Some changes can be considered precursors to the development of glycemia, although a person perceives this as an allergy, injury, or bite. Self-medication begins and the time is missed when pigmentation or rash can be reversible.
A doctor who has specialized in diabetes for many years can visually determine the etiology of any spot, redness, rash or blistering on the skin. Some changes do not require treatment because they do not cause discomfort to the patient.
But some spots, especially those with open areas of the dermis (ulcers), need to be treated comprehensively.
In addition to diet and normalization of sugars, antibiotics, antihistamines, ointments, and dressings can be used.
If the diagnosis of “diabetes mellitus” has become a life partner, you should not ignore the appearance of even a small red spot or pimple on the skin. A harmless tumor can become a serious problem. Doctors always pay special attention to feet with diabetes and recommend this to their patients.
One of the manifestations of high blood sugar levels is red spots on the legs in diabetes mellitus. They arise due to impaired patency of damaged vessels and deterioration of tissue trophism. Spots can appear not only on the legs, but also on the arms, armpits, and groin area. They usually do not cause complaints, but at the first signs of their appearance you should consult a doctor and choose the most effective method of removing pigmentation.
As you can see in the photo, pigmentation on the legs and arms are rounded formations of red or brown color. They are covered with a layer of flaky epidermis. However, not only brown spots, caused by diabetic dermatopathy, occur in a patient suffering from diabetes. The following forms of skin changes are also distinguished:
With necrobiosis lipoidica, as shown in the photo, the upper layer of the epidermis dies. As a result, red rashes appear on the legs in the area of the front surface of the lower leg. They are capable of growing to large sizes.
Dark spots with a bluish tint may appear on certain areas of the skin, which, unlike cadaveric ones, do not have a rich purple color.
This process does not cause any complaints in patients suffering from diabetes, except for the unaesthetic appearance. Treatment is recommended if there is inflammation of the dermis. This is determined by histological examination. This inflammation leads to the appearance of a pink spot of skin ulceration, causing significant pain.
Diabetic bladder most often forms on the legs in the area of the feet and legs. It is necessary to carry out the necessary treatment on time, otherwise it can grow over large areas of the skin. It is difficult to prevent the appearance of a diabetic bladder in a timely manner, since there are no inflammatory changes in the arms and legs.
Most often, blisters form on the arms and legs, in their lower parts.
Vitiligo is characterized by the formation of dark spots on the arms and legs. This pigmentation is painless. It occurs due to the fact that there is a gradual loss of pigment in the skin and dark and white areas appear. This is clearly visible in the photo.
With high insulin resistance, black pigmentation forms on the legs and arms. They can be benign or malignant. The first type is small in size and goes away on its own. Malignant pigmentation causes severe itching, peeling and an unpleasant odor. This is dangerous because a bacterial infection may occur.
The main method of control to eliminate dark spots on the legs and arms due to diabetes is to take medications that control and normalize the level of hyperglycemia. When blood sugar decreases, some of the rashes go away on their own. Severe rashes that lead to skin defects require more intensive local and general treatment.
Depending on the type of rash on the arms and legs, the following treatment methods are recommended:
If spots on the skin form due to neurological disorders, then specific treatment is necessary, which consists of prescribing B vitamins, alpha-lipoic acid, Actovegin, and anticonvulsants. The effect of treatment is not always well expressed, since manifestations of neuropathy are noticed by a patient who has been diagnosed with diabetes mellitus already at a late stage of the development of the disease.
Most often, pigmentation does not bother the patient, but with diabetes, any symptom can be a harbinger of complications!
If you have dark spots on your legs and arms, it is recommended to use only fragrance-free moisturizers. To get rid of rough skin on your feet, you can use a pumice stone, but you should not try to remove the calluses that have formed on your own. It is important to wear only comfortable clothes made from soft, high-quality fabrics, and also regularly change socks, tights and stockings.
Clothes must fit properly and not chafe or twist. If a wound forms, you do not need to cover it with a band-aid, but rather consult a doctor. Diabetes mellitus is an insidious disease that can turn even a small skin defect into a serious infected wound.
Thus, dark pigmentation on the arms and legs, which occurs in diabetes mellitus, usually does not require specific treatment and is asymptomatic. However, if formations on the skin lead to disruption of the skin, this can lead to serious complications, so it is important not to self-medicate, but to consult a doctor. To prevent the development of pigmentation and trophic ulcers, it is necessary to properly care for the skin and control blood sugar levels.
Spots on the legs in diabetes mellitus are quite common. They have a color that differs from the normal skin, most often occur on the legs, and cause significant anxiety to the patient. Why do they appear in this disease?
As you know, diabetes is a very serious chronic pathology and is characterized by metabolic disorders. This leads to changes in all structures of the body, including the skin. Almost all patients with diabetes experience certain manifestations. These include excessive dryness, itching, and dermatoses.
As a result of impaired metabolism, products of perverted metabolism accumulate in tissues and skin. This leads to inflammation in the dermis, hair follicles and glands. And since local immunity is significantly reduced, the skin becomes infected with pathogenic microflora. General disorders manifest themselves in the form of peeling, thickening, and cracking.
All skin manifestations of diabetes can be divided into certain groups:
Skin problems with primary diabetes mellitus develop as a result of damage to small blood vessels.
Clinical signs of diabetic dermopathy appear in the form of brownish spots, which are covered with scales on top. Their shape is round, and their typical location is on the lower extremities. It is detected in males with long-term diabetes.
Such spots are not accompanied by any sensations, and are often mistaken by the patient for pigmentation. The course is long, the spots disappear on their own within 1-2 years. This dermatosis does not require separate treatment.
This skin lesion in diabetes mellitus occurs only with this disease, and often for a long time is its only symptom. Fortunately, such a defeat occurs infrequently.
It occurs mainly in women, and appears in the form of spots on the legs, which are bluish-red in color. Sometimes nodular formations appear next to them. Plaques tend to merge and form large spots with areas of retraction in the center. With further progression, atrophy develops in these places, covered with telangiectasia.
As long as these places remain intact, they do not cause discomfort, but when they become ulcerated, severe pain begins.
With this deviation, whitish spots with a lack of pigment appear. Often observed in type 1 diabetes. The typical location of vitiligo is on the abdomen and chest, but can appear on the face. Treatment for this symptom is to use a steroid cream. Skin with depigmentation should be protected from sun rays with cream before going outside to avoid burns.
Skin manifestations of diabetes mellitus can occur as a result of atherosclerotic vascular damage. With insufficient nutrition, the skin atrophies, becomes thin and dry. This leads to frequent damage, and even minor scratches do not heal for a long time.
Signs of atherosclerosis are rapid fatigue when walking, and the need for frequent rest to continue movement.
The skin in diabetes mellitus also suffers when innervation is impaired. Diabetic neuropathy not only leads to changes in sensitivity, but also manifests itself in the form of blisters, which are localized on the forearms, fingers, and back. They are similar in appearance to a reaction after a burn, are not painful, and go away on their own within three weeks. The liquid in the blisters is clear, sometimes mixed with blood, and completely sterile.
It looks like a diabetes rash and has a characteristic yellow color surrounded by a red halo. Found on the back, back of the leg, buttocks. It is a companion for patients who, in addition to diabetes, have high cholesterol in their blood.
These brown spots in diabetes occur in the groin, neck and armpits. Often accompanied by cellulite and obesity.
It manifests itself as constant and painful skin itching. Sometimes this sign can be used to determine the onset of diabetes mellitus. Some believe that there is a direct relationship between the severity of the disease and the severity of itching. But this is not true, since there are severe forms of diabetes that do not manifest as such a symptom.
Occurs more often with the non-insulin-dependent variant. It appears as skin thickenings on the back of the neck with a transition to the upper back. Treatment consists of monitoring sugar levels and using a cream to soften the surface.
Signs of impaired sugar metabolism may also include pathological changes in the skin, accompanied by the addition of an infection.
Often, skin diseases in diabetes occur in the form of dermatoses with the addition of a fungal infection. They begin with severe itching in the area of the folds, and then become covered with a white coating with a loss of integrity in the form of cracks and often become ulcerated.
They are characteristic signs of the underlying disease. The patient often has pyoderma, erysipelas, phlegmon, furunculosis and other infections. Most often they are caused by staphylococci or streptococci.
Skin diseases in diabetes also often lead to ulcers and infections. The body, already weakened by the underlying disease, devotes all its strength to suppressing pathological inflammation. This leads to a general decrease in immune strength.
The skin in areas of inflammation begins to generate substances that destroy insulin. This leads to an increase in sugar and an even worse situation. It turns out to be a vicious circle, where it can be quite difficult to determine cause and effect.
In order to protect tissues from infection, a number of preventive measures are recommended. These include:
If severe damage or signs of suppuration are detected, you should not treat yourself. It is necessary to consult a doctor, since the slightest mistake in providing assistance can have fatal consequences in case of diabetes.
The modern level of medicine makes it possible to effectively combat it if the inflammatory process is detected in a timely manner. But you should remember that skin diseases in diabetes mellitus arise as a result of disturbances in sugar and other types of metabolism. Without stabilizing the condition and normalizing blood glucose levels, treatment aimed at pathological changes in the dermis itself will not bring visible relief.
In the modern world, diabetes is a common disease that affects humans. Today, the disease affects people aged 30 to 60 years. If you look at it, diabetes is a disorder of carbohydrate metabolism in the body. The reason is that human blood and urine contain large amounts of sugar, which interferes with clotting. You should know that high sugar levels cause the body to slow down metabolic processes, poorly eliminate toxins, and as a result, accompanying symptoms of the disease arise.
According to WHO, every year 2 million people die from diabetes and its complications around the world. In the absence of qualified support for the body, diabetes leads to various kinds of complications, gradually destroying the human body.
The most common complications are: diabetic gangrene, nephropathy, retinopathy, trophic ulcers, hypoglycemia, ketoacidosis. Diabetes can also lead to the development of cancer. In almost all cases, a diabetic either dies fighting a painful disease or becomes a real disabled person.
What should people with diabetes do? The Endocrinological Research Center of the Russian Academy of Medical Sciences managed to create a remedy that completely cures diabetes mellitus.
Currently, the Federal program “Healthy Nation” is underway, within the framework of which this drug is given to every resident of the Russian Federation and the CIS for FREE . For detailed information, see the official website of the Ministry of Health.
Diabetes mellitus is accompanied by problems of skin damage. The most common and unpleasant symptom is itching. The whole body itches, and the skin is severely irritated. The cause of such unpleasant sensations is high sugar levels. It clogs small vessels and crystallizes in them. The skin collects toxins and breakdown products of substances that are not removed from the body. Frequent itching disturbs a person and injures the skin. This is where various spots and redness appear. Diabetic spots come in different shapes and colors, as can be seen in the photo.
Qualified specialists note the most common types of skin lesions in diabetes mellitus:
Endocrinologists have introduced a term that characterizes spots on the legs in diabetes mellitus. The symptom is called dermopathy. The spots vary in color and size.
There is a certain algorithm and mechanisms of damage to the lower extremities:
If we take it as a percentage, then about 40% of patients suffer from diabetes spots, as shown in the photo. Also, leg diseases cause trouble not only for patients, but also for treatment specialists. Determining a concomitant disease on the skin of a patient with diabetic disease is not so easy. Redness can be caused by a variety of reasons, so you should get tested and do a full diagnosis of the body. Only based on the test results will the cause of the disease be known. If you do not do tests, then by diagnosing spots on the skin and external examination you can determine some types of diseases:

The symptoms of diabetes are varied; every twentieth person suffers from it. A large number of people have hidden diabetes or a genetic predisposition to it. Therefore, it is important to have a good understanding of the signs of the disease in order to consult a doctor for help in time.
An early sign of the disease can be a deterioration in the healing process of even minor wounds. Boils and pimples in diabetes mellitus (photo 2) are also early signs of trouble with the pancreas.
Skin itching in diabetes mellitus is observed in 80% of cases.
The disease is also indicated by increased pigmentation of skin folds and the appearance of small warts around them (acanthosis).
And such skin rashes in diabetes mellitus (photo in gal), such as diabetic pemphigus, indicate deep skin damage and require surgical intervention.
Dermatoses - spots on the legs with diabetes mellitus (pictured 3) - are most often located on the lower leg, but there are other favorite locations. White round spots - vitiligo - serve as a signal for the development of the disease. Yellow lumps – xanthomatosis – indicate increased blood sugar.
Diabetes mellitus rashes (photo in the gallery) can also appear in the form of large bluish-red spots of irregular shape, prone to enlargement. Such signs of diabetes are much more common in women than in men. This is the so-called necrobiosis lipoidica.
Gradually, the skin on the lower legs becomes thin, rough and dry. When degenerative processes intensify, ulcers appear on the legs due to diabetes mellitus (pictured 4). This process is facilitated by a decrease in sensitivity - minor abrasions and sores on the legs do not alarm a person.
The main causes of ulcers in diabetes mellitus are previous bruises, calluses and microtraumas. But the true factors that cause leg ulcers, of course, lie much deeper in the disruption of the blood supply and innervation of the lower extremities. The ulcers become infected and spread along the surface of the leg.
Skin rashes in diabetes mellitus (photo 5) take on a variety of appearances. Due to metabolic disorders, round, painless red-brown nodules 5-12 mm in diameter appear on the skin of the lower leg.
Acne in diabetes mellitus occurs due to the body's desire to remove excess glucose through the sweat glands of the skin. Reduced immunity contributes to the attachment of bacterial flora - pustules form. Diabetes rash occurs in 30-35% of patients.
Diabetes usually causes complications on the legs. Blood circulation in them is disrupted, this leads to serious consequences. Feet with diabetes mellitus (pictured 5) gradually lose sensitivity to temperature, pain and tactile stimuli.
The diabetic foot suffers from congestion in the venous system and often sends pain signals when walking, and sometimes at rest. But another condition is more dangerous - when a limb, due to the destruction of nerve endings, loses sensitivity and trophic ulcers develop on it. Redness of the leg in the form of spots indicates the development of diabetic foot. This is a late stage of the disease.
Symptoms of the disease also manifest themselves in the form of deformation of the fingers and nails. In diabetes, the toes become thicker, deformed, and red or bluish spots appear on them.
Nails with diabetes mellitus have a characteristic appearance (pictured 6): they become brittle, peel, and often grow into the skin at the corners. Often an associated fungal infection is to blame. Fragility of capillaries, especially with tight shoes, leads to hemorrhages under the nail plate, and the nails turn black.
When studying the question of what diabetes mellitus is , one cannot ignore its most serious complication - gangrene in diabetes mellitus (pictured 7), which creates a danger to the patient’s life. Non-healing leg wounds can last for several years. Their outcome is wet or dry gangrene of the lower extremities. With diabetes, this happens, alas, often after the disease has lasted for many years. Gangrene requires surgery.
Having familiarized yourself in detail with what diabetes mellitus looks like (photo in gal) at all stages, it is easier to assess the danger of its individual symptoms. Having identified signs of diabetes, you should immediately contact a specialist for help. This will make it possible to prevent serious consequences.
