Prevention

To prevent liver disease:

• Drink alcohol in moderation. For healthy adults, that means up to one drink a day for women and up to two drinks a day for men. Heavy or high-risk drinking is defined as more than eight drinks a week for women and more than 15 drinks a week for men.
• Avoid risky behavior. Use a condom during sex. If you choose to have tattoos or body piercings, be picky about cleanliness and safety when selecting a shop. Seek help if you use illicit intravenous drugs, and don't share needles to inject drugs.
• Get vaccinated. If you're at increased risk of contracting hepatitis or if you've already been infected with any form of the hepatitis virus, talk to your doctor about getting the hepatitis A and hepatitis B vaccines.
• Use medications wisely. Take prescription and nonprescription drugs only when needed and only in recommended doses. Don't mix medications and alcohol. Talk to your doctor before mixing herbal supplements or prescription or nonprescription drugs.
• Avoid contact with other people's blood and body fluids. Hepatitis viruses can be spread by accidental needle sticks or improper cleanup of blood or body fluids.
• Keep your food safe. Wash your hands thoroughly before eating or preparing foods. If traveling in a developing country, use bottled water to drink, wash your hands and brush your teeth.
• Take care with aerosol sprays. Make sure to use these products in a well-ventilated area, and wear a mask when spraying insecticides, fungicides, paint and other toxic chemicals. Always follow the manufacturer's instructions.
• Protect your skin. When using insecticides and other toxic chemicals, wear gloves, long sleeves, a hat and a mask so that chemicals aren't absorbed through your skin.
• Maintain a healthy weight. Obesity can cause nonalcoholic fatty liver disease.
