If you find yourself heading to the toilet right after eating, you’re not alone. According to Dr. Salhab, a TikTok doctor, this common phenomenon is due to the gastrocolic reflex—a natural response of your digestive system.
What Is the Gastrocolic Reflex?
VeryWell Health explains that the gastrocolic reflex triggers movement in your lower gastrointestinal (GI) tract after eating. When your stomach stretches to accommodate food, it sends signals to your brain, which then prompts your colon to contract. These contractions make room for the new food, causing you to need the restroom. However, what comes out isn’t the meal you just ate—it’s digested food and water that was already in your colon.
Heightened Reflex in IBS
For individuals with irritable bowel syndrome (IBS), this reflex can be overly sensitive, leading to painful cramps, diarrhea, or other digestive issues after eating. The Cleveland Clinic notes that IBS symptoms include gas, bloating, and abdominal discomfort.
Managing Symptoms
If your gastrocolic reflex is particularly strong, dietary adjustments, stress management, and consulting a healthcare professional can help ease symptoms.
Advice
Dr Salhab also suggests potentially steering clear of ‘carbonated beverages, alcohol, certain citrus foods, sometimes dairy as well and fried or fatty foods’ – so anything that tastes great basically.
