The liver is a very versatile organ, and it is very important to keep it healthy. The most common sign of an unhealthy liver is jaundice. Jaundice is the yellowing of the skin due to increased levels of bilirubin present in the bloodstream.
Some other signs of liver dysfunction include fatigue, sluggish metabolism, indigestion, constipation, problems processing fatty foods, problems processing alcohol, gallstones, blood sugar problems, overheating of the body, abnormalities in HDL and LDL levels and an imbalance of triglycerides.
