The digestive system is primarily a group of organs consisting of the central gastrointestinal tract and its associated auxiliary organs that break down food into smaller components so that nutrients can be absorbed and assimilated.
Some diseases of the digestive system are:
Stomach flu: Stomach flu is an infection of your intestines that usually causes watery diarrhea, pain or cramps in your stomach, nausea or vomiting, and sometimes fever.
GERD: Gastroesophageal reflux disease is a condition where stomach acids flow back into the ducts that connect the mouth to the stomach.
Hemorrhoids: Hemorrhoids, also called piles, are swollen and inflamed veins around your anus or in the lower part of your rectum.
Constipation: Conditions in which the stool becomes hard, dry, and difficult to pass, and bowel movements do not occur frequently.
