Liver complications can arise from various causes such as infections (like hepatitis), excessive alcohol consumption, obesity, or long-term use of certain medications. Common liver issues include fatty liver disease, hepatitis, cirrhosis, and liver cancer. Symptoms may include jaundice (yellowing of the skin and eyes), fatigue, abdominal pain, swelling, and nausea. If left untreated, liver damage can progress to liver failure, which is life-threatening. Early diagnosis and lifestyle changes, such as a healthy diet, reduced alcohol intake, and regular exercise, can help manage or prevent complications. The liver is vital for detoxification and metabolism, so maintaining its health is crucial.
