"What Causes Red Patches on the Skin?"

Red Patches on Hands: Causes, Treatments, and Prevention

The appearance of red patches on the hands can stem from various causes, including infections, allergies, eczema, and psoriasis. Prompt medical attention to identify the underlying cause is crucial, along with avoiding potential allergens.

1. Infectious Factors

Infection is a common cause of red patches on the hands. Bacterial infections can lead to soft tissue redness and swelling, accompanied by evident inflammatory infiltration. Patients often experience spontaneous pain and tenderness. In such cases, anti-infective medications are necessary, which may be administered locally or systemically, with the specific treatment plan determined by a physician.

2. Allergic Reactions

Allergies are also a frequent reason for red patches on the hands. Upon contact with allergens, the skin undergoes an inflammatory response, causing capillary dilation and local congestion, resulting in red patches. If an allergic reaction is suspected, promptly discontinuing exposure to the allergen is paramount. Mild symptoms may be alleviated with topical ointments, while severe cases may require oral antihistamines.

3. Eczema

Eczema manifests on the hands as red patches or papules, accompanied by itching and scaling. Eczema patients should avoid contact with alkaline and other chemicals, emphasizing skin hydration as a key management strategy. When necessary, glucocorticoid ointments can be applied topically, or oral antihistamines may be prescribed for symptomatic relief.

4. Psoriasis

Psoriasis can also cause red patches on the hands. A chronic skin condition, it may require comprehensive treatment encompassing topical therapies, phototherapy, and systemic treatments. The specific treatment plan should be tailored by a dermatologist based on the individual's condition.

Prevention and Care Recommendations

1. Maintain Skin Cleanliness

Regardless of the cause, keeping the skin clean is a fundamental nursing measure. Use mild cleansers and avoid products with irritants.

2. Avoid Excessive Scratching

Excessive scratching can exacerbate symptoms and lead to skin breakage and infection. Control the urge to scratch and use cold compresses or anti-itch creams to relieve itching.

3. Dietary Adjustments

Diet significantly impacts skin health. Incorporate foods rich in vitamins and minerals while reducing spicy, greasy, and allergenic foods to improve skin conditions.

4. Moisturize Regularly

Especially for eczema patients, maintaining skin hydration is crucial. Choose a moisturizer suitable for your skin type and apply regularly, particularly after washing hands.

5. Regular Follow-Ups

Whether due to infections, allergies, eczema, or psoriasis, regular follow-ups enable physicians to monitor disease progression and adjust treatment plans accordingly.

The occurrence of red patches on the hands is not uncommon, but the underlying causes can be diverse. Seeking prompt medical attention, adhering to treatment recommendations, and incorporating daily care can effectively alleviate symptoms and improve skin health. We hope these suggestions are helpful and wish you a speedy recovery!
