How long it generally takes to recover from liver damage is related to the cause of liver damage and the degree of damage, and requires a case-by-case analysis. When the liver is affected by pathogenic factors and there is damage to the morphological structure of the liver and abnormal liver function, it is called liver damage. If the liver damage is caused by drugs, alcohol or fatty liver, and the transaminases are not significantly elevated, below 100 U/L, they can gradually return to normal in about 2 weeks by removing the causative factors and actively treating the liver. If the damaging factors persist or the degree of liver damage is more severe, with transaminases above 200 U/L, the time to return to normal is relatively long, taking about 3-6 months or even more than 1 year. People who often take drugs, drink alcohol or overeat should be alerted to the presence of liver damage if they experience nausea, general weakness, loss of appetite, aversion to oil and sclera yellowing, etc. It is recommended to go to the liver department of a hospital for liver function tests and other related tests in a timely manner to clarify the condition and then follow medical advice for treatment to avoid delaying the condition and aggravating the degree of liver damage.
