Diabetic sores vary but often appear as painless blisters (bullae) on hands/feet, reddish-brown scaly patches (necrobiosis lipoidica), or deep, crater-like ulcers with callused edges, sometimes showing black tissue (ischemic) or drainage and odor (infection). Look for early signs like redness, warmth, or slow-healing wounds, especially on the feet, as they can indicate serious complications needing immediate medical attention, notes this article from the American Academy of Dermatology and this source from the American Diabetes Association.
People with slow-healing wounds caused by diabetes may have the following signs or symptoms:
Localized itching is often caused by diabetes. It can be caused by a yeast infection, dry skin, or poor circulation. When poor circulation is the cause of itching, the itchiest areas may be the lower parts of the legs. You may be able to treat itching yourself.
Signs and symptoms of early-stage diabetic foot ulcers
In the early stages, DFUs may present with: Redness and swelling: The affected area may appear red and swollen, often accompanied by warmth. Skin changes: The skin may show signs of thinning or may appear dry and cracked, making it more susceptible to injury.
There are several key factors in the appropriate treatment of a diabetic foot ulcer:
Diabetic blisters might be irregular in shape, large (up to 6 inches across), cluster or form as a single lesion, fill with clear fluid, and cause itchiness to the affected area. In most cases, the skin surrounding the lesions appears healthy and unaffected.
When diabetes affects your skin, your blood sugar may have been too high over time.
Avoid sugary drinks whenever possible because not only can they raise blood sugar levels, but they can also contribute many calories to the recommended daily calorie intake.
When kidneys cannot remove waste from your body, a rash can develop. One rash that occurs in people who have end-stage kidney disease causes small, dome-shaped, and extremely itchy bumps. As these bumps clear, new ones can form. Sometimes, the small bumps join together to form rough, raised patches.
How do diabetic foot ulcers form? Ulcers form due to a combination of factors, such as lack of feeling in the foot, poor circulation, foot deformities, irritation (such as friction or pressure), and trauma, as well as duration of diabetes.
Five early signs of diabetes include frequent urination, increased thirst and hunger, fatigue, blurry vision, and slow-healing sores or frequent infections, stemming from high blood sugar levels that affect the body's ability to use glucose for energy, leading to these common symptoms.
There are many types of antibiotic ointments that can be used for diabetic wound care. Some common ones include bacitracin, neomycin, and polymyxin B.
Take care when cleaning your skin
Do not shower more than once a day, and for no longer than five minutes. Keep the water temperature below 37°C. If you bathe, use a moisturizing oil – try not to use bubble bath or bath salts.
What other conditions can cause itchy skin?
Diabetic dermopathy is a skin condition characterised by light brown or reddish, oval or round, slightly indented scaly patches most often appearing on the shins.
Fruits to avoid with diabetes
While you don't need to avoid these high glycemic fruits, you should limit or eat them in moderation: Bananas. Mangoes. Pineapple.
Examples of the worst foods for diabetics include:
Aim for at least eight cups of water per day and try to drink a glass of water first thing in the morning.
Physical symptoms: reduced activity, low energy, tiredness, decreased physical endurance, increased effort to do physical tasks, general weakness, heaviness, slowness or sluggishness, nonrestorative sleep, and sleepiness.
How To Manage Diabetes Skin Problems
The Early Warning Signs
Among its many complications, diabetic foot ulcers represent one of the most disabling and life-threatening outcomes, affecting up to one-third of individuals with diabetes and serving as the leading cause of nontraumatic lower-limb amputations worldwide.
A foot ulcer looks like a round red crater in the skin bordered by thickened callused skin. Severe ulcers can be deep enough to expose tendons or bones. However, other symptoms may not be easy to identify or could be an indication of another problem.
Apply an antibiotic ointment or petroleum jelly to the blister and cover it with a nonstick bandage or gauze pad. After several days, cut away the dead skin. Use tweezers and scissors that you sterilize with an antiseptic wipe or rubbing alcohol. Apply more ointment and a bandage.
