What could cause redness in the palms?

Generally, redness of the palms may be caused by external factors, liver palms, contact dermatitis, lupus erythematosus, diabetes, and other conditions. A detailed analysis is as follows:

1. External Factors

When the palm sustains trauma or excessive friction, local capillaries may rupture or become congested, causing redness. Local pain and swelling may occur, and severe cases may be accompanied by subcutaneous bruising or bleeding. Minor injuries can be relieved by ice compresses. If open wounds or severe swelling occur, timely medical attention is required for disinfection, dressing, or further treatment.

2. Liver Palm

Due to impaired liver function and estrogen metabolism, elevated estrogen levels in the body may stimulate capillary dilation, causing redness in the thenar and hypothenar areas of the palm. Besides palm redness, symptoms such as spider angiomas, jaundice, fatigue, and loss of appetite may also appear. Treatment should target the underlying liver disease, such as antiviral therapy and liver protection, while also focusing on dietary and lifestyle adjustments.

3. Contact Dermatitis

After contact with allergens or irritants, localized immune reactions can trigger skin inflammation and redness. Symptoms include redness and itching of the palms, possibly accompanied by erythema, papules, and vesicles; severe cases may present with exudation or erosion. Avoid contact with allergens and treat with antihistamines and topical corticosteroids. Wet compresses may be used when necessary to alleviate symptoms.

4. Lupus Erythematosus

When the immune system attacks the body's own tissues, it can cause inflammatory skin reactions, and red patches may appear on the palms. The palms may show light red spots, possibly accompanied by systemic symptoms such as fever, chest pain, palpitations, and difficulty breathing, as well as other skin manifestations like joint pain and oral ulcers. Treatment typically involves corticosteroids and immunosuppressive drugs, and it is important to avoid sun exposure and other factors that may exacerbate the condition.

5. Diabetes

Poor blood glucose control in diabetic patients may lead to microvascular disease or peripheral neuropathy, affecting circulation in the palms and causing redness. Red palms may be accompanied by pain, numbness, or other symptoms of peripheral nerve damage, or may be related to blood glucose fluctuations and skin infections. Strict blood glucose control and medications to improve microcirculation are recommended. Treatment for skin infections or allergic reactions may be necessary when indicated.

To ensure safety, if palm redness is accompanied by unexplained pain, persists for a prolonged period, affects daily life, or presents with any of the aforementioned severe symptoms, prompt medical attention is recommended to obtain professional diagnosis and treatment. Additionally, maintaining good personal hygiene habits and avoiding potential allergens and infection sources can help prevent related problems.
