1. Children with henoch-schonlein purpura should immediately stop eating foods that may cause allergies, such as milk, fish, shrimp, crab, mutton, seafood and other exotic protein, to avoid contact with suspicious allergens.
2. The diet should be light, nutritious, easy to digest and absorb, and avoid some improper eating practices. Avoid fatty diet and overeating every meal, so as not to increase the burden on the gastrointestinal tract and induce or aggravate gastrointestinal bleeding. People with severe abdominal pain or positive fecal occult blood should fast if they eat liquid food and have obvious bleeding in the digestive tract.
3. Children with henoch-schonlein purpura should be treated with caution when they have abdominal pain and bloody stool. Try to use less coarse grains or foods with more crude fiber, such as celery, rape, bamboo shoots, pineapple, etc., which can damage gastrointestinal mucosa and induce or aggravate gastrointestinal bleeding.
4. Avoid alcohol, tobacco and spicy food, so as not to induce or aggravate gastrointestinal bleeding.
