In daily life, many people will have anal itching. Especially in hot weather or excessive sweating, this phenomenon will be more obvious. As long as we pay attention to the hygiene of anus and choose to wear some comfortable underwear, this phenomenon will be alleviated soon.
However, many people will have repeated itching of the skin around the anus, accompanied by other discomfort. If this phenomenon occurs, it must be noted that it is most likely a symptom of some diseases. Now, let's give you a detailed introduction.
What are the causes of pruritus around the anus?
1、 Anal eczema
Anal eczema refers to an inflammatory skin disease that occurs in the anus. It is a type of eczema. The cause of the disease is generally related to the failure of health work, or allergy and other factors. If suffering from acute anal eczema, the patient's skin around the anus will show some erythema and papules. In severe cases, there will even be some small blisters around the anus, which will be accompanied by very serious pruritus.
When suffering from chronic anal eczema, the patient's skin around the anus will have some dark red spots. There will be papules and scales on the spots, and even mossy skin changes. In addition, patients will have repeated perianal pruritus in their daily life.
2、 Anal pruritus
Anal pruritus refers to the severe pruritus that occurs in the anus and surrounding skin. This phenomenon is different from anal eczema. There will be no rash, vegetations or infection. It is generally due to some bad living habits, drug factors, or excessive sweating, fungal infection, suffering from some chronic diseases, etc. Once suffering from anal pruritus, there will be very obvious pruritus around the anus, which will spread to both sides of the hip groove and scrotum. Especially in patients with large emotional changes, eating some pepper, or sleeping at night, this itching phenomenon will be particularly serious.
Hemorrhoids is a kind of congestion phenomenon of venous plexus at the lower end of anal canal or rectum, which is divided into internal hemorrhoids, external hemorrhoids and mixed hemorrhoids. Especially when suffering from external hemorrhoids, itching will appear around the anus. If there is some inflammation, pain will appear around the anus, and blood will accumulate under the skin to form some lumps. When patients defecate, they will also have particularly obvious pain and bloody stool.
4、 Condyloma acuminatum
Condyloma acuminatum is a sexually transmitted disease caused by infection with human papillomavirus, also known as genital warts. Once suffering from condyloma acuminatum, the patient's external genitalia and the skin around the anus will appear some small reddish particles, accompanied by pruritus, foreign body sensation, surface erosion, ulceration and bleeding. If it is a female patient, it will also discharge vaginal secretions with obvious odor.
If the phenomenon of anal pruritus occurs repeatedly in daily life, it is generally related to the above four diseases. In addition, if infected with pinworm, there will be repeated perianal skin pruritus. Therefore, once this problem occurs repeatedly, we must go to the hospital quickly and give corresponding treatment according to the etiology. In addition, in daily life, we must do a good job in cleaning the anus, and don't wear some tight underwear, which can effectively reduce the symptoms of anal pruritus.
