There are many ways to protect the liver in life, such as reducing alcohol consumption, adjusting lifestyle, paying attention to the use of medication, and actively treating related diseases. There is no such thing as the fastest and best way. 1. Reduce alcohol consumption: Long-term or heavy alcohol abuse can easily cause fat accumulation and form alcoholic fatty liver, if not intervened in time, alcoholic fatty liver can develop into alcoholic cirrhosis or even liver cancer. Quitting or reducing alcohol consumption can help reduce liver damage and protect liver function. 2. Lifestyle adjustment: Obesity, long-term intake of high-fat and high-sugar food, hyperlipidemia, and drinking a lot of sugary drinks are all risk factors that can easily lead to fatty liver, therefore, we should pay attention to adjusting the lifestyle, such as controlling body weight, eating a balanced diet, reducing the intake of high-fat food, and trying to drink more water instead of all kinds of beverages. 3. Pay attention to the use of drugs: many drugs have hepatotoxicity, improper use or long-term use is easy to induce liver injury, such as acetaminophen, isoniazid, sulfonamides antibiotics, etc., the use of large amounts in a short period of time is likely to induce acute liver injury or even liver failure. Therefore, it is recommended that patients should not use the drugs on their own, and should monitor the liver function regularly and adjust the drugs in time when they need to take the drugs for a long time. 4. Actively treat related diseases: viral hepatitis, bile duct stones, primary biliary cholangitis and other liver and gallbladder diseases can lead to progressive decline in liver function, and therefore should be actively treated, such as viral hepatitis, regular antiviral treatment, bile duct stones should be operated in time to remove the stones.
