What causes pompholyx?

Generally, dyshidrotic eczema may be caused by excessive sweating, psychological factors, genetic predisposition, allergic reactions, fungal infections, and other factors. If patients experience discomfort due to dyshidrotic eczema, they should seek timely medical attention for targeted treatment to avoid delaying the condition. Specific causes are analyzed as follows:

1. Excessive Sweating

When sweat ducts become blocked, excess sweat accumulates within them, leading to the formation of dyshidrotic eczema. Patients can use normal saline to wipe the skin, or alternatively clean the skin with warm water or soapy water, which may help alleviate symptoms of blocked sweat ducts.

2. Psychological Factors

Prolonged mental stress may lead to autonomic nervous system dysfunction, thereby triggering dyshidrotic eczema. Patients are advised to relieve stress through activities such as listening to music or taking walks.

3. Genetic Factors

Dyshidrotic eczema is a blistering skin condition that symmetrically affects the hands and feet, often accompanied by symptoms such as excessive sweating of the palms and soles and peeling skin. If one or both parents have dyshidrotic eczema, their children are more likely to develop the condition. Patients should visit a hospital to identify the underlying cause and receive timely treatment.

4. Allergic Reactions

Consuming allergenic foods or exposure to allergens such as pollen or house dust mites may trigger skin allergic reactions, leading to symptoms such as blisters and itching. After the blisters dry up, skin peeling may occur, contributing to the development of dyshidrotic eczema. Patients may follow medical advice to use medications such as calamine lotion, urea ointment, or erythromycin ointment for treatment.

5. Fungal Infection

Like tinea manuum and tinea pedis, dyshidrotic eczema is also associated with fungal infection. When large numbers of fungi proliferate on the skin of the hands and feet, an eruptive reaction may occur, potentially inducing dyshidrotic eczema. Patients may follow medical guidance to take medications such as loratadine tablets, cetirizine hydrochloride oral solution, or dexamethasone acetate tablets.

In daily life, patients are advised to maintain a balanced diet, ensure adequate sleep, and avoid excessive fatigue.
