Skin conditions are often seen as a cosmetic issue that can be easily treated with over-the-counter creams and ointments. However, some skin conditions can be a sign of an underlying health condition that needs medical attention.

Here are three skin conditions that can be linked to serious diseases.

1. Celiac disease and dermatitis herpetiformis

Celiac disease is a genetic autoimmune disorder in which the consumption of gluten damages the small intestine and prevents nutrient absorption.

Dermatitis herpetiformis (DH) is a skin condition that causes itchy, blistering rashes on the elbows, knees, buttocks, and scalp. Although DH can occur independently, it is most commonly seen in people with celiac disease.

The link between celiac disease and DH is due to the immune system’s response to gluten. When people with celiac disease consume gluten, their immune system mistakenly attacks the small intestine and triggers an inflammatory response.

This autoimmune reaction can also cause DH.

It’s important to note that not all people with DH have digestive symptoms of celiac disease. In fact, up to 25% of people with DH may have no gastrointestinal symptoms at all.

That’s why it’s crucial to get tested for celiac disease if you have DH, even if you don’t have digestive symptoms.

2. Lupus and butterfly rash

Lupus is a chronic autoimmune disease that can affect various parts of the body, including the skin, joints, and internal organs. One of the most common skin symptoms of lupus is a butterfly-shaped rash across the cheeks and nose, called a malar rash.

The butterfly rash is caused by the inflammation of the skin and blood vessels in the affected area. Although the butterfly rash is a trademark sign of lupus, not all people with lupus have this rash.

In fact, some people with lupus may have other types of rashes or no skin symptoms at all.

If you have a butterfly rash, it’s important to get tested for lupus. Lupus can cause serious health complications if left untreated, including kidney failure, lung disease, and heart problems.

3. Diabetes and skin infections

Diabetes is a chronic disease that affects the body’s ability to produce or use insulin, resulting in high blood sugar levels. High blood sugar levels can damage blood vessels and nerves throughout the body, including the skin.

As a result, people with diabetes are more prone to skin infections.

Common skin infections in people with diabetes include bacterial infections, fungal infections, and staph infections.

These infections can be more severe and harder to treat in people with diabetes, as high blood sugar levels can make the immune system less effective in fighting infections.

It’s crucial for people with diabetes to take good care of their skin to prevent infections.

This includes keeping the skin clean and dry, moisturizing regularly, avoiding scratching or picking at the skin, and promptly treating any cuts or wounds.

Conclusion

Although skin conditions can be frustrating and embarrassing, they can also be a sign of a serious health condition.

If you have a persistent skin condition, it’s important to consult with a dermatologist or other healthcare provider for a proper diagnosis and treatment plan. By addressing the underlying health condition, you can not only improve your skin but also protect your overall health.
