Milk and IBS: Lactose, Fat, and Symptom Timing
Milk can trigger IBS through lactose malabsorption, fat load, or protein sensitivity. Some people react quickly, while others notice delayed bloating and stool changes later in the day.
Why Milk Can Flare IBS
- Lactose can ferment and increase gas, distension, and urgency
- Fat content may worsen post-meal cramping in sensitive patterns
- Large recurring portions in coffee and cereal make exposure easy to miss
How to Test
Remove milk for 3 weeks, then challenge with a small measured serving. Compare regular and lactose-free options in separate weeks and track symptoms over 24-72 hours.
