Jaundice is a condition in which the skin, eyes, and mucous membranes turn yellow due to high levels of bilirubin in the blood. It commonly occurs when the liver is not functioning properly or when there is a blockage in bile flow. Causes include liver diseases like hepatitis, excessive alcohol use, or infections. Common symptoms are yellowing of skin, dark urine, pale stools, fatigue, and abdominal pain. Treatment depends on the underlying cause and may include medications, lifestyle changes, or medical procedures. Early diagnosis and proper care are important to prevent complications and ensure recovery.
