Dyshidrosis

Dyshidrosis, also known as dyshidrotic eczema or pompholyx, is a skin condition characterized by small, itchy blisters that develop on the hands and feet. These blisters can be painful and may cause discomfort in daily activities.

Dyshidrosis is a common skin condition that affects the hands and feet. It is classified as a type of eczema, a group of skin disorders characterized by inflammation and irritation. The condition manifests as clusters of tiny blisters, which are called vesicles, that often occur on the palms of the hands, fingers, soles of the feet, and toes. Dyshidrosis can be chronic or acute and tends to recur over time.

Types of Dyshidrosis:

There are two main types of dyshidrosis: acute and chronic.

• a. Acute Dyshidrosis: Acute dyshidrosis refers to a sudden and short-term occurrence of the condition. It is often triggered by specific factors such as exposure to allergens, excessive sweating, or stress. Acute dyshidrosis can lead to the development of tiny, fluid-filled blisters on the palms, fingers, soles, or toes. These blisters may be intensely itchy and cause discomfort. Fortunately, acute dyshidrosis tends to resolve on its own within a few weeks without leaving long-term effects.
• b. Chronic Dyshidrosis: Chronic dyshidrosis is a recurring and long-term form of the condition. Unlike acute dyshidrosis, chronic cases may persist for several months or even years. The recurring nature of this type of dyshidrosis can make it more challenging to manage and may require ongoing treatment. To prevent flare-ups and manage symptoms, patients with chronic dyshidrosis need to identify and avoid their triggers and maintain proper skin care.
