Why does my butt sweat and itch?

The distribution of sweat glands in each human body is different. Some people have particularly developed sweat glands, so sweat glands are distributed all over the body, including the buttocks, which is actually normal. If you feel itching in the buttocks, it may be perianal eczema.

Five common misconceptions about perianal eczema

1. Perianal eczema is contagious

Is perianal eczema contagious? Of course not. In fact, it is a common non-infectious skin disease in anorectal medicine. The lesions are mostly located in the skin around the anus, and sometimes spread to the buttocks, genitals or external genitalia. Rashes, erythema, erosions, scabs and desquamation may appear locally.

The main characteristics of the disease are: chapped skin, exudation, itching, and repeated attacks. The course of the disease is long and can affect men, women, young and old.

2. Scratching

Perianal eczema, itching is one of the symptoms that cannot be ignored. Many patients cannot bear the itch and scratch desperately. But be careful, if you scratch for a long time, it will cause skin damage or ulceration, causing infection. Moreover, after the patient scratches, the skin may become thicker or rough, which may lead to anal fissures.

If this is the case, the possibility of infection will increase, and the anus will become red, swollen and painful. At the same time, the lesions may spread to the perineum, scrotum, vulva, and even the buttocks.

3. Blind medication

For perianal eczema, it is not only necessary to relieve the itching, but also to treat discomforts such as moisture and skin infiltration and hypertrophy. It is said that many patients with anal eczema will apply ointments of their own choice to the affected area for treatment, which is wrong. Because covering the affected area with a layer of ointment will hinder the dissipation of moisture from the anus, causing the condition to worsen.

Some people will choose some irritating drugs, which can only "treat the symptoms but not the root cause" (can only treat the outside but not the inside). However, they all overlook this point: long-term use of many irritating drugs will destroy the physiological functions of the perianal skin and disrupt the balance. In severe cases, it will spread and deteriorate the surrounding skin, inducing more serious diseases.

4. Hot water fumigation

Fumigation and washing of the skin around the anus with hot water is indeed very popular among patients. So is it good or bad to do this? In fact, although this method can relieve the itching temporarily, this method of cleaning not only does not alleviate the condition, but makes the itching and exudation worse.

Because overly hot water will irritate the anal skin, causing increased secretions and exudation, leading to worsening local skin inflammation and making the condition uncurable for a long time. Moreover, long-term washing in a high-temperature environment will cause the skin's stratum corneum to thicken and the skin to feel worse, which will lead to a worsening of the reaction mechanism of the nerve endings and "sensory failure", making it difficult for patients to prevent and treat diseases in a timely manner.

5. Wash with soapy water

Experts say that the "itch" of perianal eczema is mainly caused by not paying attention to the details of life. These blind spots in life may cause psoriasis or fungal growth, leading to the occurrence of "itching".

Mold prefers alkaline substances, so avoid using soap or other strongly alkaline substances to clean or wipe the anus. Because this will wash away the sebum in the skin around the anus, damage the anal skin environment, and cause anal eczema.
