1. Simple purpura:

It is a mild purpura seen in healthy people. It refers to a hemorrhagic disease in which purpura appears spontaneously and repeatedly on the skin, especially on the lower limbs, without any other symptoms and can disappear on its own without treatment.

It mainly occurs in women, and the prognosis is generally good and does not pose a serious threat to health. If the purpura is mild, no treatment is required and it can usually heal on its own. You can also take some vitamin C appropriately.

2. Thrombocytopenic purpura:

It is an immune disease characterized by the presence of antiplatelet antibodies in the blood circulation, which causes excessive platelet destruction and causes purpura. In addition, certain drugs, infectious diseases, blood diseases, etc. can also cause purpura.

3. Allergic purpura:

It is a capillary allergic disease. Purpura appears repeatedly, mostly on the lower limbs and buttocks, symmetrically distributed, and appears in batches. Purpura is higher than the skin and is often accompanied by allergic rash, joint pain or abdominal pain, fever, infection, and general discomfort. After the appearance of purpura, relevant examinations should be done, such as routine blood tests, platelets, platelet antibodies, clotting time, etc. After the cause is determined, active treatment should be given to the cause.
