There are many ways to maintain a healthy liver and biliary system. They include:

• Drink alcohol in moderation or avoid alcohol. Excessive alcohol consumption over many years is a leading cause of liver disease.
  
  
• Do not take illegal drugs and use care with supplements. Only take recommended dosages of prescription and over-the-counter medications when necessary. Be aware of potential interactions of medications with each other or with other substances such as alcohol.
  
  
• Be careful when using chemicals, such as aerosol sprays, insecticides, fungicides and paint. Use the chemicals in a well-ventilated area. Cover the skin with gloves, long sleeves, a hat and a mask.
  
  
• Eat a well-balanced and nutritious diet. Restrict intake of foods with high amounts of fat and cholesterol. Increase the amount of fiber in the diet.
  
  
• Maintain a healthy weight. Obesity is a risk factor in several liver diseases.
  
  
• Exercise regularly. This helps to maintain a healthy weight.
  
  
• Practice safe sex by using a condom during intercourse. The hepatitis virus is spread through sexual contact. It can also be spread by infected needles used in tattooing, body piercing or intravenous (I.V.) drug use.
  
  
• Receive a hepatitis B vaccination if at risk for contracting the virus and natural immunity from prior hepatitis B infection is not documented by blood tests. People at a higher risk of being exposed to hepatitis B include those with multiple sexual partners, people who use intravenous drugs, health care workers, staff of institutions for people with developmental disabilities, firefighters, police officers, mortuary attendants,  daycare workers and patients with chronic liver disease.
