Digestive / VISUAL EXPLAINER
Why Can Milk Make Some People Feel Bloated?
Lactase at the small-intestinal surface splits lactose into smaller sugars that can be absorbed. When less lactose is digested, some reaches colon microbes that can produce gas. Malabsorption does not always cause symptoms and is not milk allergy.

What the illustration shows
English educational poster titled “Why Can Milk Make Some People Feel Bloated?” on a navy background. Two large panels show peach small-intestinal cells with tall surface microvilli and gold schematic lactase enzymes. On the left, an orange-and-cyan paired lactose symbol points to a surface enzyme; branching gold arrows lead to separate orange glucose and cyan galactose symbols above the brush border. White leaders identify lactose, lactase, brush border and intestinal lining. The right panel has two gold enzymes and intact lactose pairs in the lumen, with text saying some undigested lactose reaches the colon. There is no route arrow through the cells. A smaller oval colon inset shows teal microbes and gas bubbles with direct labels. An unbranded milk glass sits below. Three statements say malabsorption does not always cause symptoms, lactose intolerance is not milk allergy, and bloating alone does not identify the cause. A scale disclaimer describes the symbols as schematic. The plain navy footer carries gold AllHumanBody.com and “REAL ANATOMY. REAL KNOWLEDGE. A HEALTHIER TOMORROW.”
How to interpret this poster
- Bloating alone is not a diagnosis. Enzyme counts and microbial symbols are qualitative; no diet, supplement or testing advice.
- AI-assisted educational illustration; not physician certification, a diagnosis or individualized medical advice.
- Fine annotations require enlargement; preserve the full uncropped illustration and its qualifiers.
