What causes red spots on the body?

Small red spots on the body may be caused by mosquito bites, bodily allergies, keratosis pilaris, spider angiomas, or other reasons. 1. Mosquito bites: This situation is quite common during summer. Generally, no specific treatment is required, and the small red spots will fade after some time. 2. Bodily allergies: This condition is also relatively common. It is necessary to identify the allergen and avoid further contact with it. 3. Keratosis pilaris: This phenomenon usually does not require treatment. The small red spots will gradually disappear on their own and are considered normal; there is no need to be overly alarmed. 4. Spider angioma: This condition is caused by liver disease. When the liver sustains a certain degree of damage, it leads to metabolic disturbances in liver function and impaired inactivation of estrogen. This results in excessive accumulation of estrogen in the body, causing skin capillaries to dilate outward and form small red spots resembling spiders.
