Symptoms of vaginal itching during pregnancy

Many women do not know what symptoms there are for vaginal itching. They just hear people talking about the serious nature of this symptom. However, if women who have not really faced this symptom do not know the symptoms of this disease, then once the disease occurs, they will not know what method to use to improve it. There are actually many symptoms for vaginal itching. Let's take a look at them together:

Genital diseases

The skin lesions of tinea cruris often extend to the vulva, causing severe local itching. The local itching caused by vulvar eczema and neurodermatitis is more severe. The former is manifested as papules and blisters with unclear local skin boundaries and erosion exudate, while the latter often causes thickening of the skin with lichenification due to scratching. In addition to causing local itching, leukoplakia of the vulva is often accompanied by vulvar malnutrition and skin atrophy.

Viral infection

Genital warts mostly occur on the female vaginal wall, cervix and vulva, and may also cause foul-smelling leucorrhea. Molluscum contagiosum occurring in the vulva often presents as round papules with an umbilical-like depression in the center, and may also cause itching in the vulva. Genital herpes is often manifested by the appearance of bright, rice-sized blisters on the urethral opening and vaginal wall, in addition to local itching.

Sexual allergy

It is an allergic reaction that occurs during sexual intercourse. There are people who are allergic to semen, condoms, and friction.

Anal itching

It usually occurs more often in middle-aged men, but women can also get the disease, and children with pinworm infection can also get it. The itching is usually confined to the skin around the anus, but may spread to the skin of the perineum, vulva, or scrotum. Anal itching caused by pinworm infection is more common in children and often worsens at night. Pinworms or eggs can be found (the positive rate is higher at night). Anal itching in adults is often caused by hemorrhoids, anal fissures, etc. There are also many patients who cannot find the cause, and the symptoms of anal itching are very severe. Due to frequent scratching, the anal folds may develop secondary damage such as hypertrophy, radial fissures, infiltration, lichenification or eczematous changes.

Vulvar dystrophy

For a long time, the symptoms of severe itching of the vulva, hypopigmentation and whitening of the skin and mucous membranes, and local thickening and coarsening of the skin have been collectively referred to as vulvar leukoplakia, but there has been no unified diagnostic standard. Later, the International Vulvar Research Organization decided to cancel the name of vulvar leukoplakia and renamed the disease "chronic vulvar dystrophy." As a result, many people have misunderstood this disease, thinking that it is like general systemic malnutrition. Some patients ask doctors in outpatient clinics: Am I lacking any food? How can I be malnourished?

In fact, the exact cause of this disease is still unclear. Some people have conducted experiments in which they exchanged the diseased vulva skin with normal skin on the patient's thigh. After a period of time, they found that the transplanted skin turned normal, while the normal skin transplanted to the vulva turned into diseased skin again. Therefore, it is speculated that the neurovascular dysfunction deep in the vulva may lead to nutritional imbalance in the skin covering the surface. Studies have shown that tissues in various parts of the body rely on nerve regulation to ensure adequate blood supply so that they can absorb nutrients. If the nutrition supply is insufficient for a long time, it will inevitably lead to pathology. Vulvar malnutrition refers to local lesions and has no direct relationship with the overall nutritional status.

In the past, many people believed that vulvar leukoplakia was a precancerous lesion and advocated early removal of the diseased tissue, but practice has shown that the recurrence rate is quite high. However, some experts conducted long-term follow-up and found that the cancer rate in patients with chronic vulvar malnutrition is only about 2%. The key is that for some patients with severe symptoms that have not been effectively treated for a long time, as well as those with ulcers, nodules and other lesions on the vulva, a part of the tissue should be selected for pathological examination in time.

Other causes

When women suffer from diabetes, due to the irritation of the vulvar skin by urine sugar, they are prone to complications of bacterial vulvar and vaginitis, causing vulvar itching. When jaundice occurs due to liver, gallbladder and other diseases, vulvar itching may also occur due to the increase of bilirubin in the blood and the irritation of the skin by bile salts. In addition, some women may experience vulvar itching due to psychological factors when they are under stress.

If you have similar problems when you are young, then when you face the symptoms of genital itching, you can judge what disease you have according to the special effects. Only after finding the cause can you treat the symptoms in time, and there will be obvious improvement after such treatment. When improving genital itching, you must also take good care of personal hygiene.
