Usually, how long it takes to recover from moderate fatty liver depends on the cause of the disease and the specific fat content, and cannot be generalized. Depending on the cause, if the moderate fatty liver is caused by long-term overeating, high-fat and high-calorie diet, as well as lack of physical exercise, the liver can be completely restored to its normal form in 3-6 months after reasonable treatment and diet adjustment. In case of moderate fatty liver caused by heavy alcohol consumption and other reasons, some patients may need more than 1 year to gradually return to normal. In addition, depending on the fat content, patients with 10% fat content are more likely to recover than those with 25% fat content. Patients with moderate fatty liver are advised to follow a low-salt, low-fat and low-sugar diet, pay attention to balanced nutrition, avoid smoking and alcohol, take rest, avoid staying up late, do proper exercise and review liver function regularly.
