Indigestion can lead to many health problems like flatulence, abdominal pain, acidity, constipation and loose motions. Digestion of food begins in your mouth and then moves to the stomach and then to the intestines. Food is broken down and absorbed by the body. The waste products from the digestion process are eliminated through the anus and this is called defecation. Proper digestion of food is essential for a healthy body. Your eating habits and activities directly affect the digestion process. You can keep your digestive system healthy and strong by changing your lifestyle or eating habits.
