Allergic purpura is an inflammatory vascular metaplastic disease, the common symptoms mainly include skin purpura, joint swelling, gastrointestinal discomfort and so on. If the disease is mild, after active and standardized treatment, most of the patients with allergic purpura have a good prognosis and will not affect the normal life expectancy and can survive for a long time, but there is a certain possibility of recurrence. If you find out that you are suffering from allergic purpura, you should go to the hospital in time and choose non-steroidal anti-inflammatory drugs, glucocorticoids, immunosuppressants, anticoagulants, and anti-allergy and antihistamine drugs for treatment under the guidance of doctors. If the above-mentioned methods are not effective, or if there are multiple relapses of the disease, plasma exchange and leukocyte removal can be used to relieve the discomfort. However, if the treatment is not carried out in time and the disease is serious, and the patient has serious complications in the kidneys and intestines, such as nephrotic syndrome, renal failure and other kidney lesions with edema, hematuria and proteinuria; or it causes intestinal lesions such as enteritis and intussusception with severe vomiting, abdominal pain and bloody stools, it may have an impact on the life expectancy of the patient. It is suggested that patients with allergic purpura should avoid contact with allergens in daily life; their diet should be light, and they should eat less or no spicy and stimulating food; they can also enhance their physical fitness through proper exercise, such as playing Tai Chi and jogging, to help recover from the disease.
