It indeed is a liver problem and it indicated that there is fat accumulated in your liver. However, it is not just a liver problem and it is one of the manifestations of a complete metabolic problem.
Liver is a store house. Whatever we eat, the excess amount is converted to fat and is stored in the liver. If on a daily basis, we have a positive balance between calories we eat and calories we burn, the difference is converted to fat and stored in the liver. Over a period of time the fat accumulated to such a great extent that it starts damaging your liver cells and they start dying. This is the time when your liver function tests start becoming abnormal. If no corrective action is taken at that moment, the liver tries healing itself with abnormal fibrosis and eventually it becomes cirrhosis. Once cirrhosis happens, it is irreversible and can then lead to all complications like blood in vomit, blood in stools, abnormal behavior, fluid accumulation in your tummy and swelling of your feet. It then remains no different from the damage caused by alcohol! So fat is as bad for your alcohol as alcohol.
Non alcoholic fatty liverdisease is characterized by increased accumulation of fat, especially triglycerides, in the livercells. It is normal for the liver to contain some fat and by itself, this causes no symptoms.
Nonalcoholic fatty liver disease occurs in every age group but especially in people in their 40s and 50s who are at high risk of heart disease because of such risk factors as obesity and type 2 diabetes. The condition is also closely linked to metabolic syndrome, which is a cluster of abnormalities including increased abdominal fat, poor ability to use the hormone insulin, high blood pressure and high blood levels of triglycerides, a type of fat.
All the recent studies in last decade have shown that the fatty liver problem is not just limited to liver. It is a marker of a complete abnormal profile. You can simultaneously have diabetes, hypertension, cardiac problems, thyroid problems, abnormal lipid profiles, menstrual problems, PCOS, gout, narrowing of your neck vessels, obstructive sleep apnea, kidney disease, arrhythmias, stroke, obesity and a complete metabolic syndrome. Once you are detected with fatty liver you should not ignore and rule out simultaneous all these problems.
