Doctor shares what it means if you always need to poo immediately after you eat (it isn’t just IBS) | June 26, 2025

If you’ve ever felt the sudden urge to head to the bathroom right after eating, you’re not alone.  This phenomenon is more common than you might think, and it’s called the gastrocolic reflex.

Dr. Joseph Salhab recently explained this process, which isn’t caused by food moving instantly through your digestive system but by signals sent between your brain and your stomach.

But what can you do to manage this reflex, especially if you have Irritable Bowel Syndrome (IBS)? Well, we wrote about it here, but here are some great foods and supplements to help manage these symptoms, along with other helpful tips like trying the FODMAP diet and incorporating aloe vera with water.

Low-FODMAP Foods

For people with IBS or who are more sensitive to the gastrocolic reflex, a low-FODMAP diet can be incredibly beneficial.

FODMAPs are specific carbohydrates that are hard to digest and can worsen symptoms like bloating, cramping, and diarrhea.

The diet eliminates certain carbohydrates that are difficult for the body to digest, which can trigger symptoms like diarrhea and cramping.

Foods like oats, quinoa, carrots, and spinach are easy on the digestive system and can help reduce post-meal trips to the bathroom.

This diet can help “reduce the strength of the contractions in the colon” for those with IBS, according to Dr. Salhab.1 You can read more about low-FODMAP diets here.

2. Bananas

Bananas are one of the best foods for soothing the digestive system. They are high in soluble fiber, which helps bulk up stool and regulate bowel movements.

Additionally, bananas help replenish electrolytes, especially potassium, which is essential for proper digestive function.

Eating a banana can help manage sudden urges to use the bathroom by providing a calming effect on the gut.

3. Ginger

Ginger has long been known for its soothing properties when it comes to digestion. Ginger can help alleviate cramping and discomfort after eating, particularly for those with IBS. It works by calming the digestive system and reducing inflammation, which can make the gastrocolic reflex less severe. Incorporating ginger into your meals or sipping on ginger tea after eating can help ease digestive issues.

4. Plain Yogurt (With Probiotics)
