Endocrine, nutritional, and metabolic diseases (E00-E90).
- Food intolerances* due to enzymatic intolerances – intolerance due to pathophysiologic disorders such as enzyme deficiency (fructokinase, lactase).
- Bacterial overgrowth of the small intestine (if necessary, H2 breath test for glucose); the small intestine abkterielle overgrowth (as a cause of food intolerance) should be excluded with positive H2 breath test for fructose, lactose, sorbitol (if necessary, also lactulose)!
Infectious and parasitic diseases (A00-B99).
- Infections, unspecified
Psyche – nervous system (F00-F99; G00-G99).
- Somatoform disorders – mental illness that results in physical symptoms without physical findings to be collected.
Digestive system (K00-K93)
- Food protein-induced enterocolitis syndrome (FPIES; food protein-induced enterocolitis syndrome):
- Acute FPIES:
- Major criteria: vomiting within 1-4 hours after ingestion of the triggerMinor criteria: Pallor, lethargy, diarrhea (diarrhea) 5-10 hours after ingestion of the trigger, hypotension (low blood pressure), and hypothermia (hypothermia)Occurrence in infants when complementary foods have been introducedDifferential diagnoses: severe infectious gastroenteritis (inflammation of the gastrointestinal tract) or sepsis (blood poisoning)
- Chronic FPIES:
- Intermittent vomiting and diarrhea, which may also be bloody due to regular consumption of the triggering agent
- Acute FPIES:
Further
- Pseudoallergies – unlike allergy, this is a non-immunological intolerance reaction.
* Associated diseases in food intolerances are:
- Infections (such as lambliasis, chronic infections, or bacterial overgrowth/dysbiosis).
- Mastocytosis – two main forms: cutaneous mastocytosis (skin mastocytosis) and systemic mastocytosis (whole body mastocytosis); clinical picture of cutaneous mastocytosis: Yellowish-brown spots of varying size (urticaria pigmentosa); in systemic mastocytosis, there are also episodic gastrointestinal complaints (gastrointestinal complaints), (nausea (nausea), burning abdominal pain and diarrhea (diarrhea)), ulcer disease, and gastrointestinal bleeding (gastrointestinal bleeding) and malabsorption (disorder of food absorption); In systemic mastocytosis, there is an accumulation of mast cells (cell type that is involved in, among other things, allergic reactions). Among other things, involved in allergic reactions) in the bone marrow, where they are formed, as well as accumulation in the skin, bones, liver, spleen and gastrointestinal tract (GIT; gastrointestinal tract); mastocytosis is not curable; course usually benign (benign) and life expectancy normal; extremely rare degeneration mast cells (= mast cell leukemia (blood cancer)).
- Eosinophilic esophago-gastritis (inflammation of the esophagus and stomach).
