Explore causes and personalized insights for bloating during fasting using advanced testing with Mito Health.
Why It Happens
Bloating during fasting often arises from electrolyte imbalances, slow gut clearance, dehydration, or microbial shifts. While fasting helps gut health long term, short-term adjustments can cause temporary bloating.
Reduced Digestive Stimulation: Lack of food slows gut muscle contractions.
Microbial Die-Off: Fasting can alter the balance of gut bacteria, creating gas.
Electrolyte Depletion: Low sodium, potassium, or magnesium impair gut motility.
Dehydration: Reduced fluid intake thickens stool and delays clearance.
Stress Hormone Surges: Cortisol spikes during fasts can constrict digestion.

How to Manage
Hydrate with Minerals: Add electrolytes or a pinch of salt to water.
Stay Gently Active: Walking stimulates digestive flow.
Avoid Overdoing Caffeine: Prevent worsening dehydration and spasms.
Break Fast Carefully: Start with gentle foods like broth or steamed veggies.
Support Gut Health Between Fasts: Prebiotics, probiotics, and balanced meals matter.
Fasting-related bloating usually fades as your body adjusts — hydration and pacing help smooth the transition.
