Itchy skin is a common discomfort that many people experience at some point in their lives. But for those with diabetes, it can be more than just an occasional irritation. Diabetes can cause itchy skin, and the reasons behind it can be varied. Whether it’s a result of high blood sugar, poor circulation, or other diabetes-related complications, itchy skin can be bothersome and frustrating.
If you’re wondering, “Can diabetes make you itchy?” and what you can do about it, you’re in the right place. This blog post will explore the causes of itchy skin for people with diabetes, how to manage it, and the best treatments available.
Why Does Diabetes Cause Itchy Skin?
Itchy skin, also known as pruritus, is a common issue for people with diabetes. High blood sugar levels, circulation problems, and other complications related to diabetes can contribute to this uncomfortable symptom. Here are some of the main reasons diabetes can cause itchy skin:
1. High Blood Sugar (Hyperglycemia)
When your blood sugar is too high, it can lead to dehydration, which can dry out the skin. Dehydrated skin becomes itchy, cracked, and more prone to irritation. Additionally, high blood sugar levels can make it harder for the body to properly remove waste, which can result in a buildup of toxins in the body that may contribute to itchy skin.
2. Poor Circulation
Diabetes can affect circulation, especially in the legs and feet. Poor blood flow means that your skin doesn’t receive the nutrients and moisture it needs to stay healthy. This can cause your skin to become dry and itchy, particularly in areas with reduced circulation like your feet and lower legs.
3. Nerve Damage (Neuropathy)
Diabetic neuropathy is a condition caused by long-term high blood sugar that damages the nerves, particularly in the legs and feet. Nerve damage can lead to a range of sensations, including itching. This can be particularly bothersome because it may occur in areas where you can’t easily reach or see.
4. Infections
People with diabetes are more prone to skin infections due to weakened immune systems. Fungal and bacterial infections can cause itching and irritation. Common skin infections in people with diabetes include athlete’s foot, yeast infections, and bacterial skin infections, all of which can lead to itchy skin.
5. Dry Skin
Chronic dry skin is another problem many diabetics face, especially if blood sugar levels are poorly controlled. Dry skin, coupled with reduced circulation and nerve damage, can lead to persistent itching. If skin becomes severely dry, it can crack, which may cause further irritation and infection.
6. Diabetic Dermopathy
Diabetic dermopathy is a condition where spots or patches of skin become scaly and itchy. These patches are usually brown or red and often appear on the legs. While this condition isn’t harmful, it can cause discomfort, including itching.
What Are the Common Areas of Itchy Skin in Diabetes?
People with diabetes may experience itching in various parts of the body. However, there are some areas that are more commonly affected:
1. Feet and Toes
The feet are particularly vulnerable to itching due to poor circulation and nerve damage. People with diabetes may experience itchy feet due to dry skin, infections, or neuropathy.
2. Legs
The lower legs, especially the shins, are another area where itchy skin can occur. Diabetic dermopathy, dry skin, and circulation issues are all common causes of itching in this area.
3. Hands
Dry skin and poor circulation can also lead to itching in the hands. It’s not uncommon for people with diabetes to experience itchy palms, which can be a sign of nerve damage or dehydration.
4. Genitals
Fungal infections, such as yeast infections, are more common in people with diabetes, especially in the genital area. These infections often cause intense itching, redness, and discomfort.
5. Arms and Neck
The arms and neck can become itchy due to high blood sugar, skin infections, and dryness. In some cases, people may also experience itching due to poor circulation affecting these areas.
Can Diabetes Lead to Specific Skin Conditions That Cause Itching?
Yes, diabetes can lead to several specific skin conditions that may cause itching. Let’s take a look at some of the most common ones:
1. Eruptive Xanthomatosis
Eruptive xanthomatosis is a condition that causes yellowish bumps or nodules to appear on the skin, particularly on the back, arms, and buttocks. These bumps can be itchy and are more common in people with poorly controlled diabetes.
2. Acanthosis Nigricans
Acanthosis nigricans is a skin condition characterized by dark, thick patches of skin, often around the neck, armpits, and groin. These patches can be itchy and are sometimes linked to insulin resistance, a condition that often occurs in type 2 diabetes.
3. Fungal Infections
People with diabetes are more prone to fungal infections like athlete’s foot, ringworm, and yeast infections. These infections can cause intense itching, especially in areas like the feet, groin, and underarms.
4. Bacterial Skin Infections
Infections caused by bacteria like staphylococcus can result in itchy, painful rashes, boils, or abscesses. People with diabetes are more susceptible to these infections due to weakened immune systems.
How Can You Treat Itchy Skin Caused by Diabetes?
If you’re experiencing itchy skin due to diabetes, there are several strategies you can try to relieve discomfort and manage the underlying cause:
1. Maintain Healthy Blood Sugar Levels
The first and most important step in managing itchy skin caused by diabetes is keeping your blood sugar levels under control. By managing your blood sugar, you can reduce the likelihood of developing complications like dehydration, poor circulation, and infections that contribute to itching.
2. Hydrate and Moisturize
Dry skin is a common issue for diabetics, and keeping your skin moisturized can help prevent itching. Use a thick, fragrance-free moisturizer on your skin daily, especially after bathing. Drink plenty of water to keep your body hydrated, as dehydration can worsen itching.
3. Practice Good Skin Hygiene
Regularly wash your skin with a mild, fragrance-free soap. Avoid hot water, as it can dry out your skin further. Pat your skin dry instead of rubbing it to prevent irritation. Moisturizing right after a bath or shower helps lock in moisture.
4. Treat Skin Infections Promptly
If you suspect that your itchy skin is due to a skin infection, seek treatment from a healthcare professional. Fungal infections like athlete’s foot and yeast infections can be treated with antifungal creams or medications. Bacterial infections may require antibiotics.
5. Wear Soft, Breathable Fabrics
Wearing soft, loose clothing made of cotton or other breathable fabrics can help prevent skin irritation. Avoid wearing tight clothes that may trap moisture and contribute to itching.
6. Use Anti-itch Creams
Over-the-counter anti-itch creams or lotions containing ingredients like hydrocortisone or calamine can help alleviate itching. Always consult your healthcare provider before using any new creams or ointments to ensure they are safe for your skin and health.
When Should You See a Doctor About Itchy Skin?
Itchy skin is often a minor issue, but in some cases, it can indicate a more serious underlying problem. You should see a doctor if:
- The itching is severe and doesn’t improve with over-the-counter treatments
- You develop a rash, bumps, or blisters along with the itching
- You experience other symptoms like fever, pain, or swelling
- You notice signs of infection, such as redness, warmth, or pus
- You have trouble controlling your blood sugar or notice significant changes in your skin condition
