Although a liver should have no fat, for most people, having a small amount of fat won’t cause severe problems.
Stage 4 of NAFLD, called cirrhosis, can lead to life-threatening liver conditions including liver cancer and liver failure.
Around 20 percent of people with NAFLD go on to develop NASH, and one in five of those people go on to develop cirrhosis.
If detected and managed an an early stage, NAFLD can be stopped from getting worse.
