Gastrointestinal food intolerance
Introduction
Introduction to Gastrointestinal Food Intolerance Gastrointestinal food intolerance is a hypersensitivity reaction to the intake of certain specific foods, which can occur 1 hour after eating. Food intolerance is a reproducible IgG-mediated immune response to a specific food or food ingredient that is time-delayed (hours to days), quantitatively dependent, and cumulative. Can occur in all ages. The most common symptoms include irritable bowel, headache, migraine, fatigue, behavioral abnormalities and urticaria, and some patients can induce asthma attacks. Food intolerance is associated with a variety of chronic diseases, involving multiple systems and skins such as the digestive, nervous, and cardiovascular systems, with the digestive system being the most common. Unlike IgE-mediated allergic reactions to immediate-type foods, IgG-mediated food intolerance is a delayed response, often caused by a variety of foods. Specific IgG antibodies form an immune complex with food particles that can cause intestinal and A multi-tissue inflammatory response throughout the body. basic knowledge Sickness ratio: 5% Susceptible people: no specific population Mode of infection: non-infectious Complications: edema, urticaria, purpura, bronchial asthma, allergic rhinitis, syncope, hypotension
Cause
Causes of gastrointestinal food intolerance
Foods that cause systemic reactions are reported to have halibut, rice, shrimp, and cereals. The mechanism of food intolerance is still unclear, and may involve immune response, enzyme deficiency, pharmacological effects, etc., but does not include pathogenic microorganisms, chemical poisons, toxic food toxicity and subjective aversion to food. Common intolerance foods include: milk, eggs, wheat, corn, nuts, soya beans, and shellfish. More than 90 kinds of foods can be tested at present.
