What causes vulvar eczema? Know the cause and learn to prevent it

If vulvar eczema occurs, it means that there is a problem with the health of the genitals. There are many causes of this disease, such as mental factors, external stimulation, or allergic factors, etc., so you must learn preventive measures.

1. Mental factors are the cause of vulvar eczema

For example, mental stress, excessive fatigue, and depression can cause neuroendocrine dysfunction, which in turn increase the skin's susceptibility to various stimuli through neural reflexes or endocrine influences, thereby inducing eczema.

2. Local irritation is the cause of vulvar eczema

Increased vaginal discharge, scratching, and urinary fistula can also trigger the occurrence of eczema.

3. External allergens are the cause of vulvar eczema

External allergens generally refer to cosmetics containing chemicals, dyes, radiation, some abnormal proteins, some pollen, or dust in the air. All of these factors can cause vulvar eczema in women.

4. Allergens in the body are the cause of vulvar eczema

Such as lesions in the body, intestinal parasites, certain metabolic products, digestive tract diseases, and autoantigens produced by human tissues under the influence of certain factors.

Symptoms of vulvar eczema:

Vulvar eczema is a relatively serious skin disease among eczemas, and severe itching symptoms often occur when the disease occurs.

1. Acute phase

Erythema, edema, papules, and blisters gather in groups. Blisters may fuse, rupture, erode, exude, and form crusts. The lesions are often symmetrically distributed, relatively localized and recurrent.

2. Subacute phase

Erosion and exudation decrease, and scabs and desquamation appear.

3. Chronic stage

After the acute stage, the inflammatory response becomes milder, manifested as skin thickening, cracking, desquamation, and accompanied by pigmentation or hypopigmentation.

Systemic treatments for vulvar eczema:

Treat the cause, keep the vulva clean, avoid scratching, get enough rest, and avoid eating foods that are prone to allergies. Antihistamines and other drugs can be taken orally.

Oral antihistamines and other medications

(1) Antihistamines and other drugs

Diphenhydramine 25 mg, 3 times/d, orally. Chlorpheniramine (chlorpheniramine) 8 mg, 3 times/d, orally. For severe itching, 10 ml of 5% calcium bromide can be injected intravenously. Or intravenous injection of 10% calcium gluconate 10 ml, once a day.

(2) Vitamins

Large amounts of vitamin C can be given intravenously or orally, and B vitamins can be taken orally in conjunction with treatment.

(3) Hormones

Can be used for acute severe eczema. Prednisone, dexamethasone and other treatments can be given, which have a certain effect on eliminating inflammation, relieving itching and reducing exudate. Due to the high number of adverse reactions, care should be taken to control its use. It should not be used for chronic eczema in the elderly because it may relapse quickly after discontinuation of the drug and cause other adverse reactions.
