Causes of vulvar and anal itching

If a woman experiences itching on her vulva and anus, she should pay attention to it. There are many reasons for this symptom, the most common of which are gynecological diseases. For example, vaginitis often causes this symptom. When some infectious diseases occur, or local lesions occur in the vulva, such symptoms may be caused. In addition, if you do not pay attention to personal hygiene, this situation is also likely to occur.

Causes of vulvar and anal itching

Female vulvar itching is one of the most common gynecological symptoms. The itching areas are mostly the clitoris, mons pubis, labia majora and minora, and if the area is large, it may spread to the area around the anus. The symptoms may be mild or severe, and severe cases may make the patient restless, affecting work and rest. Repeated scratching of the vulvar skin can cause thickening of the skin, scratches, blood scabs, and lichenification. The vulva is sensitive to external stimuli. In addition, the area is wrinkled and poorly ventilated, and is often soaked by leucorrhea, menstrual blood and urine, making it prone to infection and itching.

There are many causes of vulvar itching, such as the stimulation of physical and chemical factors in daily life, systemic diseases, local vulvar lesions and infections, etc., which may become pathogenic factors, but there is also vulvar itching for which no cause can be found.

First, infectious diseases

The most common causes of vulvar itching are Trichomonas infection or fungal infection. When suffering from Trichomonas vaginitis or bacterial vaginitis, or cervical erosion, the amount of leucorrhea increases significantly, and the inflammatory secretions irritate the vulvar skin and mucous membranes, causing itching. In addition, pubic lice, pubic scabies and some sexually transmitted diseases can also cause vulvar itching. Pinworm disease is common in young girls, mainly causing itching around the anus, which may spread to the vulva and occur at night.

Second, local lesions of the vulva

Vulvar skin diseases such as vulvar eczema, neurodermatitis, chronic vulvar dystrophy, vulvar tumors, etc. can cause vulvar itching.

Bad hygiene habits

If you do not pay attention to cleaning the vulva on a regular basis, vaginal secretions or menstrual blood will accumulate in the vulva and cause itching. On the contrary, washing the vulva several times a day, or frequently using strong alkaline soaps, or washing the vulva with potassium permanganate water will make the vulva skin too dry and cause itching.

Fourth, the clothing is not suitable

For example, if you like to wear synthetic clothes or use menstrual belts made of rubber or plastic, the vulva skin will be poorly ventilated, soaked with sweat, and itchy.

Fifth, sensitive substances stimulate

Allergic reaction to systemic or topical medications may cause vulvar itching.

6. Systemic diseases

For example, vulvar itching caused by vitamin A and B deficiency, jaundice, anemia, leukemia and other diseases is part of systemic itching. The diabetes in diabetic patients irritates the vulva and is also a common factor causing itching. In addition, obese patients may experience vulvar itching due to excessive secretion of sebaceous glands and sweat glands, which stimulate the vulva.

Seven is irritation from feces and urine

A very small number of patients may experience itching due to urethrovaginal fistula, urinary incontinence, or anal fistula, which causes long-term irritation of the vulva by feces and urine.

Eight is the mental factor

Some patients are unable to find out the cause of vulvar itching, which may be due to excessive mental stress. If you are depressed, nervous, or anxious, you are more likely to develop vulvar itching.

Nine is the menstrual factor

Because menstrual blood flows through the vagina, disturbing the normal vaginal acidity and alkalinity, the previously hidden pathogens can induce infection and cause vulvar itching. In addition, direct stimulation of menstrual blood can also cause discomfort in the perineum. During menopause, the estrogen level in the body decreases and the genitals shrink, which reduces the resistance to the flora living in the vagina and makes it easy to develop senile vaginitis. The inflammatory secretions can also cause itching in the perineum.
