What Illness Causes Seborrheic Dermatitis?
There is no clear cut answer to what illness causes seborrheic dermatitis. However, there are certain underlying conditions that may be linked to an increased risk of developing seborrheic dermatitis.
Seborrheic dermatitis is a common skin condition that causes a red, itchy rash. It most often affects the scalp, but it can also occur on the face and other parts of the body. The exact cause of seborrheic dermatitis is unknown, but it is thought to be linked to an overproduction of oil in the sebaceous glands. This excess oil can lead to an infection of the hair follicles, which can then cause the characteristic rash.
There are several underlying conditions that may be linked to an increased risk of developing seborrheic dermatitis. These include:
- Dandruff: Dandruff is a common scalp condition that can cause an itchy, flaky rash. Dandruff is thought to be caused by an overgrowth of a type of yeast called Malassezia. This yeast feeds on the natural oils produced by the skin, which can lead to an infection. Dandruff is a very common condition, and it is estimated that up to 50% of adults suffer from dandruff at some point in their lives.
- Psoriasis: Psoriasis is a chronic skin condition that causes thick, red, scaly patches on the skin. It is thought to be caused by an overactive immune system. Psoriasis can affect any part of the body, but it is most commonly found on the scalp, elbows, and knees. Psoriasis is a fairly common condition, and it is estimated that up to 3% of adults suffer from this condition.
- Eczema: Eczema is a chronic skin condition that causes dry, itchy, red patches on the skin. It is thought to be caused by a combination of genetic and environmental factors. Eczema most commonly affects infants and children, but it can also affect adults. Eczema is a relatively common condition, and it is estimated that up to 20% of children suffer from eczema at some point in their lives.
Seborrheic dermatitis is a condition that causes the skin to become irritated and flaky. It is often caused by an overgrowth of the yeast that lives on the skin. Seborrheic dermatitis can also be caused by certain medical conditions, such as psoriasis, eczema, or dandruff.
While these underlying conditions may be linked to an increased risk of developing seborrheic dermatitis, they are not necessarily the cause of the condition. Seborrheic dermatitis can occur in people of any age and without any underlying conditions.
If you have seborrheic dermatitis, you may notice that your skin is:
- Greasy or oily
- Flaky or scaly
Seborrheic dermatitis is most common in adults. It is also more likely to occur in people who have oily skin or who are overweight. Seborrheic dermatitis is not contagious.
If you think you have seborrheic dermatitis, see your doctor. He or she can prescribe medicated shampoos, creams, or ointments to treat the condition.
