Question: What is (are) Cyclic Vomiting Syndrome ?
Answer: The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anusthe opening through which stool leaves the body. The body digests food using the movement of muscles in the GI tract, along with the release of hormones and enzymes. Cyclic vomiting syndrome affects the upper GI tract, which includes the mouth, esophagus, stomach, small intestine, and duodenum, the first part of the small intestine. The esophagus is the muscular tube that carries food and liquids from the mouth to the stomach. The stomach slowly pumps the food and liquids through the duodenum and into the rest of the small intestine, which absorbs nutrients from food particles. This process is automatic and people are usually not aware of it, though people sometimes feel food in their esophagus when they swallow something too large, try to eat too quickly, or drink hot or cold liquids.

Question: What are the treatments for Cyclic Vomiting Syndrome ?
Answer: A health care provider may refer patients to a gastroenterologist for treatment. People with cyclic vomiting syndrome should get plenty of rest and take medications to prevent a vomiting episode, stop an episode in progress, speed up recovery, or relieve associated symptoms. The health care team tailors treatment to the symptoms experienced during each of the four cyclic vomiting syndrome phases: - Prodrome phase treatment. The goal during the prodrome phase is to stop an episode before it progresses. Taking medication early in the phase can help stop an episode from moving to the vomiting phase or becoming severe; however, people do not always realize an episode is coming. For example, a person may wake up in the morning and begin vomiting. A health care provider may recommend the following medications for both children and adults: - ondansetron (Zofran) or lorazepam (Ativan) for nausea - ibuprofen for abdominal pain - ranitidine (Zantac), lansoprazole (Prevacid), or omeprazole (Prilosec, Zegerid) to control stomach acid production - sumatriptan (Imitrex)prescribed as a nasal spray, an injection, or a pill that dissolves under the tonguefor migraines - Vomiting phase treatment. Once vomiting begins, people should call or see a health care provider as soon as possible. Treatment usually requires the person to stay in bed and sleep in a dark, quiet room. A health care provider may recommend the following for both children and adults: - medication for pain, nausea, and reducing stomach acid and anxiety - anti-migraine medications such as sumatriptan to stop symptoms of a migraine or possibly stop an episode in progress - hospitalization for severe nausea and vomiting - IV fluids and medications to prevent dehydration and treat symptoms - IV nutrition if an episode continues for several days - Recovery phase treatment. During the recovery phase, drinking and eating will replace lost electrolytes. A person may need IV fluids for a period of time. Some people find their appetite returns to normal right away, while others start by drinking clear liquids and then moving slowly to other liquids and solid food. A health care provider may prescribe medications during the recovery phase and well phase to prevent future episodes. - Well phase treatment. During the well phase, a health care provider may use medications to treat people whose episodes are frequent and long lasting in an effort to prevent or ease future episodes. A person may need to take a medication daily for 1 to 2 months before evaluating whether it helps prevent episodes. A health care provider may prescribe the following medications for both children and adults during the well phase to prevent cyclic vomiting syndrome episodes, lessen their severity, and reduce their frequency: - amitriptyline (Elavil) - propranolol (Inderal) - cyproheptadine (Periactin)
