What Causes Itchy Anal Area?
Anal itching is a common anorectal disease that causes unbearable discomfort, often leading people to scratch uncontrollably. Itching in the anal region is often caused by hemorrhoids, perianal eczema, intestinal parasitic infections, etc. In particular, recurrent hemorrhoids can easily stimulate the skin around the anus, causing chronic inflammation and leading to anal itching. When anal itching occurs, it is crucial to seek immediate medical attention for examination and treatment.
1. Hemorrhoids are a common type of disease affecting the anus and rectum. When hemorrhoids repeatedly protrude, intestinal fluid can continuously stimulate the skin around the anus, causing chronic inflammatory changes that lead to itching and discomfort in the anal region.
2. Perianal eczema is an allergic non-communicable skin condition affecting the perianal area. It is often associated with moisture in the perianal region, manifesting as itching and discomfort accompanied by symmetrical rash formation.
3. Intestinal parasitic infections, commonly caused by Enterobius vermicularis (pinworms), often reside in the large intestine. When the anal sphincter relaxes, adult worms may crawl out of the anus to lay eggs, causing anal itching.
There are various causes of anal itching. When experiencing anal itching, it is important to consult a qualified doctor in the gastroenterology department or dermatology department of a hospital to determine the underlying cause and receive targeted treatment. With appropriate treatment, most cases can be cured, preventing serious clinical consequences.
