Children's physical health is an issue that parents are most concerned about. Parents all hope that their children can grow up healthily. However, since children's organs are not fully developed, they are easily invaded by the outside world and develop some diseases. Therefore, parents can understand the symptoms and causes of some common childhood diseases, and try to help children avoid these common diseases in daily life. Let's take a look at the following introduction to children's allergic purpura.

Allergic purpura is also called hemorrhagic capillary poisoning, which is a common microvascular allergic hemorrhagic disease. The causes include infection, food allergies, drug allergies, allergies caused by pollen, insect bites, etc., but the cause of allergies is often difficult to determine. It is more common in children and adolescents.

There is often a history of upper respiratory tract infection 1 to 3 weeks before onset. It manifests as skin petechiae, which mostly appear around the joints of the lower limbs and buttocks. Purpura is symmetrically distributed, appears in batches, varies in size, and varies in color. It can merge into pieces and usually gradually disappears within a few days, but can recur. Patients may have gastrointestinal symptoms, such as paroxysmal abdominal colic or persistent dull pain; they may have joint pain; kidney symptoms, such as proteinuria and hematuria, are more common in children. Treatment includes trying to find the cause of the allergy and avoiding it; using antihistamines such as diphenhydramine, promethazine, ancillary drugs, chlorpheniramine, etc. and corticosteroids, etc.
