Hi, Thanks for your question. After going through your question in your father s case there is likely possibility of Alcoholic Liver Disease, though other short term illnesses can lead to similar finding. For better opinion I want to know- 1) Duration of taking alcohol. 2) Pattern and amount of taking alcohol. 3) Presence of any other diseases and treatment for it. 4) Current symptom for which admitted to hospital. I would like to advise following tests- 1) Complete blood count. 2) Liver function test. 3) Kidney function test. 4) Urine examination. 5) Ultrasonography of abdomen. 6) In case of fever Tests for malaria, dengue or any other infections if clinically indicated. Depending upon his detailed clinical examination and test reports it is possible to comment whether liver damage is permanent or reversible, and also appropriate diagnosis can be made and treatment can be planned. In general for recovery from liver disorder or to prevent further damage to liver - 1) He has to stop taking alcohol in any form permanently. 2) Avoid taking oily, fatty food till recovery. 3) Taking food containing high carbohydrates (only if non diabetic) 4) Avoid use of food or drugs that can aggravate liver injury.
