Limiting alcohol intake and certain medications, maintaining a healthy diet, and establishing a consistent exercise regimen are some ways to improve the health of a person's liver, according to WebMD. A healthy liver involves avoiding what is harmful more than eating or drinking substances that are supportive of the liver.
Alcohol consumption can damage liver cells and cause scarring or swelling that forms into cirrhosis, explains WebMD. Cirrhosis, a deadly disease, replaces healthy liver tissue with scar tissue. The new tissue prevents the flow of blood to the liver, thereby stalling the processing of hormones, nutrients, naturally produced toxins and medications. The U.S. government advises women to have at most one alcoholic drink a day, and men to have no more than two.
By eating healthy and exercising regularly, a person can control his weight more effectively. This helps reduce the incidence of nonalcoholic fatty liver disease, a contributing factor in cirrhosis, states WebMD. Certain medications, including acetaminophen and cholesterol drugs, can cause liver damage if taken in excess. Acetaminophen is in many cold medications and prescription drugs. Combined with alcohol, some medications can cause significant liver damage as well.
Hepatitis is harmful to a person's liver, WebMD notes. Avoiding risk factors that lead to hepatitis, such as the sharing of needles, toothbrushes and razors, and being tested regularly are helpful. Limiting the number of sexual partners and using a condom with intercourse also reduces a person's likelihood of contracting the disease.
