Have you ever found yourself rushing to the bathroom right after eating? According to one doctor on TikTok, if this happens to you, you're not alone — and there’s a scientific explanation behind it.
What Does It Mean?
The doctor clarifies that needing to use the bathroom immediately after eating doesn’t mean the food you just consumed is speeding through your digestive system. Instead, this phenomenon is linked to something called the gastrocolic reflex.

What Is the Gastrocolic Reflex?
According to VeryWell Health, the gastrocolic reflex is a normal, physiological response that occurs in your digestive system. It triggers movement in the lower gastrointestinal (GI) tract after eating, making room for more food.
Dr. Salhab, who frequently shares medical insights, explains it further:
“When you eat, your stomach stretches, which sends signals to your brain. The brain then communicates with your colon, causing it to contract. These contractions help make space for the new food by moving along stool and water already in the colon.”
What comes out when you use the restroom is not the food you just ate. It’s actually stool and water left over from food that was digested earlier.

A Heightened Reflex
For some people, this gastrocolic reflex can be particularly strong. Those with irritable bowel syndrome (IBS), for example, may experience exaggerated symptoms.
The Cleveland Clinic describes IBS as a condition that causes uncomfortable or painful abdominal symptoms. Common signs include constipation, diarrhea, gas, and bloating.
Dr. Salhab notes, “In some cases, people may experience severe abdominal cramping or even diarrhea after eating because the colon’s contractions are unusually powerful.”
Tips for Managing Symptoms
If you’re dealing with an overly sensitive gastrocolic reflex, there are ways to ease the discomfort. Dr. Salhab recommends avoiding:
- Carbonated beverages
- Alcohol
- Citrus fruits
- Dairy products
- Fried or fatty foods
While these may be some of the tastiest treats, avoiding them could help reduce symptoms and make mealtimes more comfortable.
In summary, the gastrocolic reflex is a normal bodily response, but it can be more intense for some individuals, particularly those with IBS. If this happens to you regularly and impacts your daily life, consider consulting a healthcare professional for personalized advice.
