wie wird eiweiß verdaut — what symptoms are typical?

Protein digestion starts in the stomach with pepsin and hydrochloric acid, continues in the small intestine with pancreatic enzymes (trypsin, chymotrypsin), and ends with amino acid absorption. Typical symptoms of impaired protein digestion include bloating, fullness, nausea, fatty stools (steatorrhea), and undigested food in stool. Causes may include enzyme deficiency (e.g., exocrine pancreatic insufficiency), low stomach acid, celiac disease, or inflammatory bowel disease. A MyBody-X test offers limited help: DNA tests can reveal variants in genes like PNLIP or CTRC that influence pancreatic risk but do not diagnose. Microbiome tests may indicate dysbiosis affecting protein utilization. For persistent symptoms, consult a doctor for stool tests (elastase, calprotectin) or breath tests (lactose, fructose). Evidence for home tests in this area is weak; they are adjunctive, not diagnostic.
