Splenomegaly caused by fatty liver will take about two to three months or half a year to recover with regular treatment, or it may not recover. Whether the splenomegaly can get better depends on whether the portal hypertension can get better or not, and whether the portal hypertension can get better or not depends on whether the cirrhosis can be reversed or not. If the cirrhosis has already caused the portal hypertension, the cirrhosis can not be reversed in general, and the portal hypertension can not be reversed in general, so the splenomegaly can not get better either. Splenomegaly caused by fatty liver may be clinically recognized as cirrhosis caused by fatty liver, i.e., steatohepatocirrhosis. When cirrhosis is treated routinely, it usually takes one to three months of treatment time, and the recovery time is about half a year. The specific recovery time varies according to the patient’s own condition, and may not be able to recover for a long time. When splenomegaly caused by fatty liver occurs, you should actively control your diet, try to eat less high-fat and high-sugar food, avoid eating greasy food, etc.; eat more high-protein food, vegetables and fruits. It is recommended to consult the doctor in time and standardize the medication and treatment under the doctor’s guidance to avoid delaying the condition.
