Hi dear Thanks for choosing HCM. by low blood count do they mean low Hemoglobin?! Enlarged liver can be caused by many reasons that can t be counted here, but mainly due to Hepatitis Infection (A,B,C or E), it can also be due to Alcoholic or non-alcoholic fatty liver disease, history of medication drugs abuse, there are other causes such as Hepatocellular carcinoma etc Overall the doctors have to run more tests such as blood test that is known as Liver function test to show us how the liver is functioning or if there is any kind of infection, they might also consider doing abdominal ultrasound or CT scan to look at the liver more clearly also please mention to the doctor if your partner had recently had any episodes of black stools (medically known as Malena) as that could be a sign that he has upper GI bleeding. people with liver disease develop some sort of thing known as portal hypertension which could lead to bleeding in the Gastrointestinal system mainly esophagus or stomach. Based on your question it seems like the Doctors are still running some other tests to confirm, so please don t over think and try to stop worrying, until the doctors give you a final diagnosis and treatment. Wish you all the best and hope your partner gets better soon.
