Food Intolerance

The goal of this interventional study is to compare two different sizes of a gastrostomy tube in children and the incidence of complications three months postoperatively. The study is questionnare-based and both the family and health care personel will fill in the formula about complications at the re-visit when the tube is changed the first time at three months postoperatively. Complications requested are: granuloma, infection, pain, dislocation and leakage.

Food intolerance (FI) is an adverse reaction to food caused by non-immune mechanisms, mainly related to digestive enzyme deficiencies (e.g. lactase deficiency), metabolic abnormalities (e.g. impaired absorption of fructose) or toxicity of food components (e.g. histamine). Unlike immune-mediated food allergy, FI symptoms are usually delayed (hours to days after ingestion) and mild, but are difficult to diagnose and manage clinically due to the complexity and variety of mechanisms that affect approximately 20% of the world's population.

The FARE Patient Registry will serve as a prospective, observational food allergy reporting system that stores detailed health and other basic information about patients' real-world experiences with food allergies, to encourage open sharing of de-identified data and participation in clinical trials. The FARE Patient Registry intends to make and support scientific discoveries by enabling the food allergy community to participate directly in research.
