    Co-Morbid - Related illnesses (i.e., arthritis, hypertension) or disabling conditions related to clinically severe obesity or obesity-related health conditions

    Colon - Large intestine beginning at the end of the small intestine and ending at the rectum

    Contraindications - Any symptom or circumstance indicating the inappropriateness of an otherwise advisable treatment (i.e., alcoholism; drug dependency; severe depression; sociopathic (antisocial) personality disorder)

    Digestion - Process in which food is broken down by the stomach and upper small intestine into absorbable forms

    Dilation - Process of enlarging or further opening a passage or anastomosis

    Disease - Process that is a hazard to health and/or longevity

    Divided Gastric Bypass Surgery - Surgical operation that provides a way to manage clinically severe obesity

    Dumping Syndrome - Uncomfortable feeling of nausea, lightheadedness, upset stomach, vomiting, and/or diarrhea, related to ingestion of sweets, high-calorie liquids, or dairy products

    Duodenum - First 12 inches of small intestine immediately below the stomach. Bile and pancreatic fluids flow into the duodenum through ducts from the liver and pancreas.

    Back to Topic

    Gastric Bypass Surgery - Operation designed to make non-functional a portion of the stomach

    Gastric Sleeve - The gastric sleeve involves removing 2/3 of the stomach with a stapling device and is the first part of a duodenal switch operation. It leaves a stomach tube instead of a pouch. In the case of a super morbidly obese person, this operation is offered because it allows good weight loss so the patient can get to a safe weight for the more radical bypass operation which can be done laparoscopically.
