[|Human|] hi, my teenage brother has an enlarged spleen, hes had it for a long time now, the doctor keeps doing ultrasounds and has confirmed that is is getting bigger. however he can not figure out what is causing it. he has done some blood tests to rule out leukemia. the doctor now says that because he doesnt know what the cause is, he wants just keep waiting and watching out for symptoms, while being careful not to do anything that could make it burst. also im not sure if this could be related at all, but he also had his gallbladder removed due to gallstones, and it was because of his gallbladder problems that his enlarged spleen was discovered.
[|AI|]  Hi and welcome to Chat Doctor. Thank you for your query. I am Chat Doctor, I understand your concerns and I will try to help you as much as I can. Enlarged spleen is called splenomegaly and there are various causes possibly leading to this. In first case these are infections such as mononucleosis Parasitic infections, such as toxoplasmosis or Bacterial infections. It means that any infection in your body may lead to spleen enlargement.  Second most common causes include autoimmune diseases such as thrombocytopenia. If this is ruled out by specific tests then some other causes may be considered and some are more or less serious such as Leukemia Lymphoma, or noninflammatory diseases such as acidosis, lupus, and rheumatoid arthritis. In every case, infectious causes are treated with antibiotics and other causes may require surgical removal of spleen. I hope I have answered you query.
