Medical Terms and Meanings
Acid Reflux: A condition in which contents from the stomach flow back up into the esophagus, often causing a painful sensation behind the breast bone called “heartburn.”
Amino Acids: Compounds containing nitrogen that form the building blocks of proteins. A protein is composed of chains of many amino acids. Some amino acids are considered nutritionally essential and must be supplied by the diet.
Anemia: Having too few red blood cells.
Chronic Diarrhea: Frequent, loose, and watery bowel movements on an ongoing basis.
Dehydration: Excessive loss of body fluid through frequent urinating, sweating, chronic diarrhea and/or vomiting.
Dysphagia: Difficulty swallowing.
ELISA Testing: The Enzyme-Linked Immunosorbent Assay (ELISA) is an advanced laboratory test used to detect small amounts of specific proteins.
Enteral Feeding: Taking nutrition into the body through the digestive system either orally or via a tube.
Eosinophil: Specialized white blood cells produced in increased numbers in many allergic conditions.
Eosinophilic Colitis: Condition in which the lining of the large intestine (colon) becomes filled with eosinophils, often causing nausea, vomiting, and diarrhea.
Eosinophilic Esophagitis: Condition in which the wall of the esophagus (the muscular tube through which food is sent from the mouth to the stomach) is infiltrated by eosinophils. Symptoms can include abdominal pain, nausea, vomiting, coughing, and failure to thrive.
Eosinophilic Gastroenteritis: Condition in which the lining of the stomach, small intestine, and large intestine is infiltrated by eosinophils, resulting in diarrhea and possibly vomiting, cramps, and lack of appetite.
Eosinophilic GI Disorders (EGID): Group of conditions in which part or all of the lining of the gastrointestinal system (esophagus, stomach, small and large intestines) becomes filled with large numbers of eosinophils. Symptoms can include nausea, vomiting, diarrhea, and failure to thrive.
Food Allergy: A reaction of the body's immune system to food proteins. The reaction can become stronger each time the individual is exposed to the protein and can become life-threatening in rare cases. The most common food protein allergies are to cow's milk, eggs, peanuts, tree nuts, fish, shellfish, wheat, and soy.
Galactosemia: A buildup of the sugar galactose in the blood. This occurs when a body lacks the enzymes needed to break down galactose into usable glucose. Too much galactose can damage the liver, eyes, brain, and kidneys.
Gastrostomy Tube (G-tube): A tube placed in the stomach that provides an alternate way to offer food and/or medicines. It also can be used to vent your child's stomach for air or drainage.
Gluten: A protein in grains such as wheat, rye, and barley.
Hypoallergenic: A product that is less likely to cause an allergic reaction. Abbott Nutrition manufactures three clinically documented hypoallergenic formulas: Similac Expert CareTM Alimentum®, EleCare®and EleCare®Jr.Intestinal Adaptation:Process in which the small intestine increases in size so it has more surface area through which to absorb nutrients. This often occurs after bowel resection surgery.
