Evidence check: Fitness | LifestyleCheck in the context of Langlebigkeit

Feeling bloated with a belly that looks pregnant, especially after meals, is a common complaint. Potential causes include food intolerances (lactose, fructose, FODMAPs), gut microbiome imbalance (e.g., low Bifidobacteria), small intestinal bacterial overgrowth (SIBO), or delayed gastric emptying. Stress and eating habits (fast eating, large portions) also contribute. Practical solutions: a low-FODMAP diet, increasing prebiotic fibers (e.g., oats, chicory), and probiotics like Bifidobacterium strains. A microbiome test can offer insights but is not diagnostic. Caveat: evidence for DNA-based personalization for bloating is weak (mechanistic, not clinically validated). If symptoms persist or are severe, consult a gastroenterologist to rule out conditions like celiac disease or IBS. These recommendations are based on clinical practice and observational evidence, not strong RCTs.
