Did You Know!
Your Stomach Can Grow New Layers Every Few Days
The human stomach completely regenerates its inner lining about every 3–4 days.
- This happens because stomach acid is strong enough to dissolve metal — it’s made of hydrochloric acid, which can corrode razor blades in lab experiments.
- Without this constant regeneration, the acid would literally digest the stomach itself!
- This rapid renewal also explains why ulcers can heal quickly if treated properly.
