Patient's question:
I noticed a few days ago that my child developed purpura on their body. At that time, I was very worried and took them to the hospital for a thorough examination. The doctor prescribed some medication for them and also said that if you have this condition, you should pay attention to your diet, as some foods can be harmful to the condition. What should children with allergic purpura eat?Doctor's answer:
The causes of allergic purpura include infectious agents, food allergies, drug allergies, pollen, insect bites, and other allergic reactions. It manifests as skin petechiae, frequently recurring around the lower limb joints and buttocks. The purpura appears bilaterally symmetrically, with varying sizes and shades of color, and can merge into patches. It generally gradually fades within a few months but can recur repeatedly. Treatment includes identifying and preventing the allergen, using antihistamines such as diphenhydramine, hydroxyzine, chlorpheniramine, and levocetirizine, as well as corticosteroids.
