Two separate issues here. A mildly raised bilirubin with otherwise normal
liver tests, seven months after stopping alcohol, is often Gilbert's syndrome, a harmless inherited variation that rises with fasting, stress or illness. The low sodium is very likely from drinking about 15 litres of water a day, which dilutes blood sodium and can become dangerous.
Next Steps
Please cut your water intake to roughly 2.5-3 litres a day (more only if you sweat heavily) and recheck serum sodium after a week. Get
LFT with direct and indirect bilirubin, CBC, reticulocyte count, serum
electrolytes,
TSH, cortisol if advised, and an ultrasound abdomen. Continue complete alcohol abstinence. You are welcome to consult me on Practo or at Synergy Miraj with your reports so we can interpret them together.
