Anal itching makes people miserable and seriously affects the daily life of the patient. So, why does the anus often itch? How should we deal with the frequent itching of the anus?
Anal pruritus refers to a skin disease with no primary skin damage but only itching symptoms. Can be divided into primary pruritus and secondary pruritus. Primary pruritus has unknown causes and is not easy to treat; while pruritus confined to the anus is often secondary to anorectal diseases. After the cause is removed, it can often be cured.

(1) Spicy food irritation: Excessive consumption of peppers, spices, and white wine can induce the disease.
(2) Allergic reactions: certain proteins (fish, shrimp, crab, etc.), drugs, pollen, etc. can cause allergies to the human body, produce excessive histamine, and act on peripheral nerves to cause itching.
(3) Medical diseases: Endocrine disorders, accumulation of metabolites such as bile acid and urea in the body, malnutrition, certain blood diseases, etc.;
(4) Mental factors: excessive excitement, depression or neurasthenia, etc.

(3) Anorectal diseases: anal fistula, hemorrhoids, prolapse, anal sinusitis, anal papillitis, anal incontinence, etc. stimulate the anal glands, increase the secretion of glandular fluid, cause the anus to become wet, irritate the skin, and cause itching.

The harm of anal pruritus
In the early stage of the disease, it is limited to the itching of the skin around the anus, sometimes severe and sometimes mild, sometimes stinging and sometimes burning, sometimes like insects and ants, sometimes like mosquito bites, sometimes itching is unbearable, and it is even worse at night, making people sit Restless. Scratching makes the skin ulcerated, oozes, scabs, and does not heal for a long time, resulting in thickening around the anus, thick and rough wrinkled walls, showing radial folds, lichen change, pigmentation or depigmentation, and even spread to the perineum, scrotum, Labia or sacrum. After being ill for a long time, it is easy to chap afterwards. Over time, it can cause neurasthenia, lethargy, lack of taste when eating, and sleeplessness at night.
