warum gluckert mein bauch — which blood markers matter?

Stomach gurgling (borborygmi) is usually a normal sign of digestion and peristalsis, not a disease. There are no specific blood markers that directly explain why your stomach makes noise. However, if accompanied by bloating, pain, or irregular stools, certain blood tests may be considered: celiac serology (tTG-IgA), CRP for inflammation, or a complete blood count. IgG food sensitivity tests are not recommended by major allergy societies (EAACI, AAAAI, DGAKI) because they measure normal exposure, not intolerance, and can lead to unnecessary dietary restrictions. For most people, stomach noises are benign and do not require blood work. If symptoms persist, a hydrogen breath test for lactose/fructose malabsorption or SIBO is more evidence-based than blood markers. The evidence for routine blood markers in isolated borborygmi is weak; focus on clinical context.
