What is the difference between anal itching and vulvar itching?

Anal itching and vulvar itching are diseases that most people currently suffer from. In clinical practice, if people want to distinguish between the two, they need to understand the difference between the two as introduced below.

Anal itching

It refers to a skin disease in which the skin around the anus has no primary skin lesions but only itching symptoms. This disease often occurs in young and middle-aged people between 20 and 40 years old. It affects males more than females, and is more common in those who are inactive.

Causes

1. Food factors

Excessive consumption of spicy foods and condiments, such as chili peppers, alcohol, mustard, pepper, spices, coffee, etc., can cause irritation to the anal canal and anal skin, and induce itching.

2. Allergic reaction

Certain proteins (fish, shrimp, crab, etc.), medicines, pollen, lacquer, etc. can cause allergies in some people, causing excessive histamine to be produced in the body, which acts on the peripheral nerves and causes itching.

3. Mental factors

Mental overexcitement, depression, neurasthenia, addiction, etc.

4. Fungal and viral infections of the perianal skin

Common infections include epidermophyton and other infections.

Vulvar itching

It is a very common symptom of gynecological diseases. The vulva is a particularly sensitive area. Various gynecological diseases and external stimuli can cause itching, making people unable to sleep or eat, and unable to sit or lie down. Vulvar itching often occurs on the clitoris and labia minora, and may also affect the labia majora, perineum and perianal area.

Causes

1. Chronic local irritation, irritation from abnormal secretions of vulva, vagina and cervix inflammation;

2. Unclean vulva and tight synthetic underwear, sanitary napkins, etc. lead to poor permeability;

3. Vulvar parasitic diseases, such as pubic lice, pinworms, scabies, etc.;

4. Various vulvar skin diseases and vulvar tumors, etc.;

5. Local vulvar symptoms of systemic diseases, such as diabetes, uremia, vitamin deficiency, etc.
