There are 2 types of causes for increased platelet. No 1;Primary where bone marrow produce more platelet and cause is not known called as primary thrombocytes. This type is congenitally inherited that is pass from parents to children. No 2;Secondary. In this platelet increase in response to many diseases in body. There is long list of diseases but most common are;Cancer of gut, breast, lung, ovary and lymphoma Iron, deficiency anemia and hemolytic anemia, After spleen surgery, Inflammatory bowel diseases and some infective diseases. There is no vitamin or Chat Doctor. It has to be investigated and treated. I would suggest out consult a hematologist who may be able to evaluate you for your increased platelet and may treat accordingly. Hope this answers your question. </s>
