Red spots appearing on the palm can have several possible causes, commonly including:
1. Allergic reactions: Contact with certain substances such as detergents, cosmetics, or food allergies can cause red spots to appear on the skin.
2. Dyshidrotic eczema (sweat duct inflammation): In hot and humid environments, blocked sweat glands can prevent sweat from being excreted normally, causing small blisters or red spots.
3. Autoimmune diseases: Conditions such as psoriasis and lupus erythematosus may also cause red spots to form on the palms.
4. Drug reactions: Certain medications may trigger skin allergies, manifesting as red spots or rashes.
5. Fungal infections: For example, ringworm, commonly found in damp environments, can cause red patches, itching, and peeling skin.
6. Viral infections: Such as hand, foot, and mouth disease or herpes, which can cause red spots or blisters to appear on the palms.
Maintaining clean and dry hands and avoiding known allergens may help prevent some of these conditions. The above list includes only possible causes, and the specific diagnosis should be determined based on individual circumstances and medical evaluation. If discomfort occurs, it is recommended to seek medical attention promptly for examination.
