Idiopathic thrombocytopenic purpura, also known as autoimmune thrombocytopenic purpura, is the most common type of thrombocytopenic purpura and is characterized by shortened platelet life span, increased bone marrow megakaryocytes, and accelerated platelet renewal rate. Epistaxis, gum bleeding and oral mucosal bleeding, and blood blisters may be present. In women, excessive menstruation may be seen. Severe bleeding may lead to large skin petechiae, hematomas, or bleeding from the gastrointestinal and urinary tracts, or even life-threatening intracranial bleeding. Long-term disease may include anemia and hepatosplenomegaly. Commonly used drugs are glucocorticoids prednisone, dexamethasone, immunosuppressants such as vincristine, cyclophosphamide, etc. 1. Avoid taking glucocorticosteroids with calcium-containing foods because taking glucocorticosteroids with calcium-containing foods (such as milk, dairy products, refined white flour, chocolate, nuts, etc.) will reduce the therapeutic effect. 2. Avoid taking glucocorticosteroids with high salt diet because glucocorticosteroids have the effect of sodium and potassium retention, so high salt diet is likely to cause edema. 3. Avoid eating a lot of sugar when taking glucocorticosteroids Because glucocorticosteroids such as hydrocortisone, prednisone and dexamethasone can promote glycogen xenobiogenesis and slow down glucose decomposition, which is conducive to the resynthesis of intermediate metabolites such as pyruvate and lactate in the liver and kidney, increasing the source of blood glucose and reducing the utilization of glucose by the body tissues, thus causing blood glucose to rise. Therefore, the intake of sugar should be restricted when taking glucocorticoids. This disease is due to the internal heat of Yin deficiency or heat poisoning, forcing blood delusion, blood does not follow the normal path, overflowing in the skin. The spicy things (such as chili, garlic, etc.) can be hot fire, greasy things (such as fatty meat, fried food) can help wet heat, fire and heat of the evil forced blood delusion, blood overflow pulse outside, can aggravate the purpura. 2, avoid eating shrimp, crab The occurrence of this disease and immune factors, the spleen on platelet destruction and capillary defects and other factors. 3, avoid drinking alcohol alcohol is pungent and hot, can stimulate the skin and visceral blood vessels, increasing vascular permeability, bleeding symptoms aggravated, is not conducive to the treatment and recovery. 4, avoid eating coarse, long fiber food platelet reduction is most likely to bleed. Consumption of coarse, long fiber food, to be in the digestive process and the digestive tract mucosa a lot of friction, will lead to gastrointestinal bleeding, so must be avoided. Such foods are celery, spinach, leeks, bamboo shoots, asparagus and uncooked beef, lamb, pork, etc.. 5, avoid hot food hot food can help Yang move blood, will lead to platelet reduction patients bleeding aggravated, so should not eat it. These foods are mutton, dog meat, sparrow, venison, rooster meat, leek, lychee, silkworm moth, etc.. 6, avoid overeating platelet reduction patients are most likely to bleed, overeating can increase the burden on the digestive tract, and make a large amount of food accumulation in the stomach, thus causing gastrointestinal bleeding. The disease can be caused by drugs, so patients with this disease should not use quinidine, quinine, chloramphenicol, sulfonamides, etc., because these drugs can cause thrombocytopenia through immune action. 2, avoid anticoagulant drugs anticoagulant drugs for thrombocytopenia can make bleeding aggravated, so must be prohibited, such as bicoumarin, bicoumarin acetyl, cyclic coumarin, warfarin sodium, new anticoagulation, benzindanedione, etc. 3, avoid hot drugs hot drugs help Yang move the blood of the disadvantage, will lead to platelet reduction patients bleeding aggravated. These drugs are cinnamon, cinnamon stick, clove, horsetail, saposhnikov, dogwood, fennel, etc. 4, avoid breaking the gas drugs This disease is a weak spleen qi many people, so should not use a strong break the gas and blood products, such as trigon, curcuma longa, Lycopodium, Citrus aurantium, incense, etc.. 5, avoid the use of drugs that inhibit platelet function Aspirin, vincristine, prostacyclin, etc. have the effect of inhibiting platelet function, the use of these drugs, will make the platelet function worse, so should be avoided.
