Digestion & liver

Your digestive system runs from your mouth to your gut, with the liver, gallbladder, and pancreas doing quiet work along the way. This section covers what goes wrong there: reflux, ulcers, irritable bowel, constipation, food intolerance, hepatitis, and gallstones. You will find what causes each one, how doctors tell them apart when they share so many symptoms, and what treatment and diet changes actually help. Some signs are not ordinary indigestion: blood in your stool, unexplained weight loss, or pain that wakes you at night. Those need a doctor rather than a wait-and-see.
