Medical terms and meanings
A-D
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.
E
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:
A type of white blood cell with immune system element.
Eosinophilic Colitis (EoC):
Chronic, immune-mediated disorder with eosinophil-predominant inflammation in the colon.
Eosinophilic Duodenitis (EoD):
Chronic, immune-mediated disorder with eosinophil-predominant inflammation in the duodenum (first part of the small intestine).
Eosinophilic Enteritis (EoN):
Chronic, immune-mediated disorder with eosinophil-predominant inflammation in the small bowel.
Eosinophilic Esophagitis (EoE):
Chronic, immune-mediated disorder with eosinophil-predominant inflammation in the esophagus.
Eosinophilic Gastritis (EoG):
Chronic, immune-mediated disorder with eosinophil-predominant inflammation in the stomach.
Eosinophilic Gastrointestinal Disorders (EGIDs):
Chronic, immune-mediated disorder with eosinophil-predominant inflammation in specific regions of the gastrointestinal (GI) tract.
Eosinophilic Ileitis (EoI):
Chronic, immune-mediated disorder with eosinophil- predominant inflammation in the ileum (last part of the small intestine).
Eosinophilic Jejunitis (EoJ):
Chronic, immune-mediated disorder with eosinophil- predominant inflammation in the duodenum (middle part of the small intestine).
F-H
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.
Gastroparesis:
A condition in which the stomach cannot empty itself of food in a normal fashion.
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 Alimentum®, EleCare® and EleCare® Jr.
I-O
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.
Malabsorption:
A condition that occurs when the bowel cannot absorb enough protein, fat, or nutrients from a normal formula or diet. Symptoms often include diarrhea and weight loss. This can be due to a food protein allergy to cow's milk or soy, or other causes.
Malnutrition:
Poor nourishment of the body often due to inadequate digestion and/or absorption of nutrients, insufficient food intake, or bad eating habits.
Nasogastric Tube (NG Tube):
A small, plastic tube placed through the nose into the stomach. It is used to provide nutrients and medications until the baby can take them orally.
Oral Feeding:
Receiving nutrition through the mouth.
P-Z
PAGE Testing:
Polyacrylamide Gel Electrophoresis (PAGE) testing is used to detect small amounts of intact protein, regardless of its source. PAGE testing is one of the tests conducted on finished EleCare® products before release.
Parenteral Feeding:
Taking nutrition into the body in a way other than through the digestive system, for instance, through intravenous feeding (into a vein).
Protein:
A large complex molecule made up of one or more chains of amino acids. Proteins are needed by the body to grow and function properly.
Short Bowel Syndrome:
Malabsorptive conditions resulting from massive re-sectioning of the small intestine. Malnutrition and diarrhea are common.
Small Intestine:
The narrow, winding, upper part of the intestine where most food is digested, and most nutrients are absorbed.
Tube Feeding:
Feeding (either a special liquid formula or pureed food) that is delivered to a patient through a tube directly into the gastrointestinal (GI) tract, usually through the nose or directly into the stomach or small intestine.
