Seborrheic Dermatitis

Causes, Symptoms and Treatments of Seborrheic Dermatitis

In this article, I will discuss another common ailment that affects people all over the world. The condition, called seborrheic dermatitis or seborrhea, is a common chronic skin disorder in which red scaly patches develop on the skin that are shed off. One of the milder forms of the disease is dandruff, in which there is excessive production of skin cells and the scalp sheds off flakes. In its advanced form, the scales of seborrheic dermatitis become very irritable and start erupting. The disease can affect all parts of the body including the scalp, eyebrows, face, ears, chest, and even the back. Another form of the condition is called cradle cap, in which infants and young children get the condition on the scalp and the diaper area.

Seborrheic dermatitis is known to affect about 12% of the population, making it a common condition. It peaks in adults in the age group of 30-60 years. In younger populations, the condition is seen as dandruff. Men are more likely to be affected by the disease than women. Studies show that the disease occurs commonly during the first three months, during puberty as dandruff and then between 40 to 60 years of age as rashes and scaling.

The disease affects men more than women and often relapses. Since it is cured by sunlight, it has a seasonal pattern and is more commonly seen in winters.

Seborrheic dermatitis resembles psoriasis, and the symptoms look quite similar. While Psoriasis produces papules of scaling red skin, seborrheic dermatitis is characterized by oozing. The doctor will conduct a detailed skin analysis test. Consult a dermatologist to get proper consultation and treatment. Sometimes, clinics offer free skin analysis checkup. Search for such treatment centres around you for free consultation.

Symptoms

Seborrheic dermatitis is characterized by skin rashes and red scaling which can ooze liquid. It is accompanied by significant dandruff. The rash is distributed widely on the body including the scalp, outer ears and the auditory canal, and on face parts like forehead, eyebrows, eyelids, cheeks and nose. It may also be seen on the chest and back. It also occurs in babies as “cradle cap,” or a scalp eruption, and can be seen on the diaper area. Sometimes there may be no symptoms but simply scalp itching.

The disease begins in young people with mild greasy scaling on the scalp. In adults, the skin appears greasy and the condition is seen as uneven scaling and lesion on scalp, eyebrows and face, which are affected the most. It causes severe itching and flaking of skin and is most uncomfortable and bothersome for patients as the flakes are clearly visible on the affected parts.

Causes

Seborrheic dermatitis occurs in areas where sebum is produced heavily. It is also seen in patients with an excess of a normal skin yeast. From these two conditions, we can conclude that seborrheic dermatitis is caused by oily skin and fungal infestations. Further, it is found in patients with nervous system diseases such as dementia and brain injuries. Seborrheic dermatitis is not contagious but it looks extremely bad.

Why it happens is not fully understood. The most common cause of seborrheic dermatitis is inflammation. It is speculated that a fungus called Malassezia, which normally exists on the human skin, may be responsible. Other causes that may lead to the disease are poor immunity, stress, the existence of other diseases, or a side effect of certain psychotropic medicines. Hormonal imbalance can also trigger the disease, as well as nutritional deficiencies.

Seborrheic Dermatitis Treatment

Very often the disease clears up on its own but is known to relapse. That is why it must be treated. Seborrheic dermatitis treatment consists of implementing a skin care routine that removes excess sebum and reduces skin inflammation and itching. Medicines may be prescribed for treating fungal infection and to reduce the scaling of the skin. The condition can usually be treated by medicated shampoos and easily available medicines. For stubborn symptoms, creams may be prescribed containing weak steroids. If it is still not controlled, the doctor may prescribe stronger steroids.

Antifungal medications are effective if the infection is caused by Malassezia. Antifungal shampoos and lotions are available for use on the scalp and other parts of the body. Where the cause is not a fungal infection, topical creams or lotions containing Corticosteroids are used to reduce skin inflammation. Anti-inflammatory medications are also available. Shampoos containing coal tar, salicylic acid and zinc pyrithione can be used to treat the scalp.

Another line of treatment is light therapy. Since seborrheic dermatitis can be controlled by UV light, patients are advised to sit in sunlight for some time or undertake UV light therapy. For people who want to use herbal preparations, remedies containing Tea tree oil is quite effective. Many shampoos and oils containing tea tree oil are available in the market.

Diagnosis

It is advisable to seek medical help as the disease is known to relapse. Diagnosis is done by visual examination, going over the medical history of the patient, and by analysis of the skin scales in the laboratory. This is important as the symptoms can easily be mistaken for psoriasis or contact dermatitis. The doctor must closely check the skin for lesions, their colour and location. Sometimes the diagnosis cannot be made on the basis of skin examination alone, which necessitates laboratory tests.

Conclusion

Seborrheic dermatitis affects the most visible parts of the body. It is not a serious condition and cures of its own but affects the psychological condition of the patient. Get a free skin consultation to diagnose the problem. It can be easily treated by medicated creams, shampoos and lotions. Relapse can also be prevented through the use of antifungal shampoos and creams with mild steroids. If you are prone to this condition, follow a healthy skin hygiene and care routine. Also, moisturize the skin regularly. Patients must have a nutrient-rich diet. The important part of seborrheic dermatitis treatment is to manage the severe mental stress that patients go through because of their flaky appearance so the doctor must work as a counsellor as well.
