What is a non-alcoholic fatty liver disease EXPLAINED

Non-Alcoholic Fatty Liver Disease(NAFLD) refers to a range of conditions caused by a build-up of fat within liver cells. It is now very common and happens to most obese or overweight people.

Body Mass Index(BMI) formula and chart

BMI = weight(lbs) * 703 / height(in) 2
                           OR

BMI = weight(kg) / height(m)2

If your BMI is :

from 18.5 to 25 - normal
25 to 30 - overweight
30 to 35 - obese
35 to 40 - clinically obese
Above 40 - dangerously obese

For obese and overweight people with NAFLD, usually the advice would be to reduce or lose weight gradually. 



4 stages of NAFLD 

• Simple fatty liver (hepatic steatosis). Simple fatty liver means that excess fat builds up in liver cells. For most people, simple fatty liver does not cause any harm or problems to the liver. However, in some people it can progress to more severe forms of NAFLD.
• Non-alcoholic steatohepatitis (NASH). Basically an inflammation to the liver. This is much less common than simple fatty liver.
• Fibrosis. Persistent hepatitis may eventually cause scar tissue (fibrosis) to form within the liver. When fibrosis first develops often there are many liver cells that continue to function normally
• Cirrhosis. This is a serious condition where normal liver tissue is replaced by a lot of fibrosis. The structure and function of the liver are badly affected. Many liver conditions can lead to cirrhosis, including NAFLD. Severe cirrhosis can lead to liver failure. 

There are no symptoms to NAFLD. Some people will feel the upper right abdomen pains because of the enlarged liver. You may experience general tiredness throughout the day while certain people may not have any symptoms. 

Weight reduction would be the best advice i could give.
