The scariest part about fatty liver disease is that it's relatively symptom-free and therefore goes undetected. Many people don't realize they have it until it reaches more advanced stages. Since being overweight can damage your liver just as much as alcohol, it's important to maintain a healthy weight for a healthy liver.
Too many over-the-counter pain relievers
Acetaminophen, which you may know as Tylenol, is a popular pain reliever and fever reducer. Some people swear by it, popping it at the first sign of a headache, muscle pain, or fever. But you can have too much of a good thing; since it's metabolized by the liver, it can be toxic in high doses.
"If you take enough of it, it will cause liver damage," Dr. Olsen says. "This amount varies depending on how much alcohol you drink, and it is important to read labels because acetaminophen is hidden in a lot of combination pain medications." Cough and cold medicines, sinus medicines, and others can also contain acetaminophen, so double-check ingredients and dosage instructions.
