ABOUT THE DIGESTIVE SYSTEM The digestive system is made up of the digestive tract—a series of hollow organs joined in a long, twisting tube from the mouth to the anus—and other organs that help the body break down and absorb food. Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine—also called the colon—rectum, and anus.

WHY IT’S IMPORTANT Food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body. Digestion is the process by which food and drink are broken down into their smallest parts so the body can use them to build and nourish cells and to provide energy.

Cyclic Vomiting Syndrome CVS is characterized by episodes or cycles of severe nausea and vomiting that last for hours, or even days, that alternate with intervals with no symptoms. Common triggers include emotional stress and excitement, Anxiety and panic attacks are more common triggers in adults. Colds, allergies, sinus problems, and the flu can also set off episodes in some people.

Symptoms of CVS A person who experiences the following symptoms for at least 3 months—with first onset at least 6 months prior—may have CVS vomiting episodes that start with severe vomiting—several times per hour—and last less than 1 week three or more separate episodes of vomiting in the past year absence of nausea or vomiting between episodes

CVS TREATMENTS Treatment varies, but people with CVS generally improve after learning to control their symptoms. People with CVS are advised to get plenty of rest and sleep and to take medications that prevent a vomiting episode, stop one in progress, speed up recovery, or relieve associated symptoms.

Crohn’s disease Crohn’s disease is an ongoing disorder that causes inflammation of the digestive tract, also referred to as the gastrointestinal (GI) tract. Crohn’s disease can affect any area of the GI tract, from the mouth to the anus, but it most commonly affects the lower part of the small intestine, called the ileum.

SYSMPTOM OF CROHN The most common symptoms of Crohn’s disease are abdominal pain, often in the lower right area, and diarrhea. Rectal bleeding, weight loss, arthritis, skin problems, and fever may also occur.

treatment for Crohn’s disease Treatment may include drugs, nutrition supplements, surgery, or a combination of these options. The goals of treatment are to control inflammation, correct nutritional deficiencies, and relieve symptoms like abdominal pain, diarrhea, and rectal bleeding.

ulcerative colitis Ulcerative colitis is a disease that causes inflammation and sores, called ulcers, in the lining of the rectum and colon. Ulcers form where inflammation has killed the cells that usually line the colon, then bleed and produce pus. Inflammation in the colon also causes the colon to empty frequently, causing diarrhea

symptoms of ulcerative colitis The most common symptoms of ulcerative colitis are abdominal pain and bloody diarrhea Patients also may experience: anemia fatigue weight loss loss of appetite rectal bleeding loss of body fluids and nutrients skin lesions joint pain growth failure (specifically in children)

treatment for ulcerative colitis Treatment for ulcerative colitis depends on the severity of the disease. Each person experiences ulcerative colitis differently, so treatment is adjusted for each individual.
