Hi, How are you? My name is Dr Suresh Raghavaiah. I am a Liver and pancreas specialist and I hope to answer your question today. Fatty liver can be caused by excessive alcohol intake (Alcoholic steato hepatitis, ASH) or due to excessive fatty food intake and sedentary life style (Non-alcoholic steato hepatitis, NASH). ASH is usually the beginning stages of alcohol induced liver damage and is completely reversible if the patient refrains from alcohol. NASH is being much more commonly diagnosed currently owing to poor dietary habits and sedentary life styles of people. High caloric intake, high fatty food intake and poor exercise regimens lead to deposition of fat goblets in the liver tissue leading to fatty liver (which shows up as increased echo texture on USG). This is also completely reversible in the initial stages if caloric intake is limited and exercise regimens are adhered to. If left un-checked, patients usually become obese, diabetic and in final stages may lead to cirrhosis of the liver which will necessitate a liver transplant. I would suggest a healthy diet and exercise regimen. Although there is no time limit on when to get a repeat scan, I would suggest one, once you have succeeded in losing some weight. Hope this helped and hope you start to feel better. Please do not hesitate to contact me for further details. Have a great day. Dr Suresh Raghavaiah
