Do you often have to poop right after eating? An expert reveals what it means

Many people assume that whatever they have just eaten goes straight through the digestive system and leaves the body almost immediately. But according to Dr. Joseph Salhab, a renowned gastroenterologist with a large following on social media, this is not true. In a conversation with his 1.8 million followers on TikTok, he explains that this rapid bowel movement has nothing to do with lightning-fast digestion.

The real reason: the gastrocolic reflex

According to Dr. Salhab, the real reason behind these hasty toilet visits is a natural bodily reaction called the gastrocolic reflex. This physiological process kicks in as soon as food reaches your stomach.

“When you eat, your stomach stretches. This sends signals to the brain, which in turn sends a message to the colon. This causes the colon to contract to make room for the new food that is coming in,” says Dr. Salhab. ”This can cause you to feel the need to go to the toilet immediately after eating.”

In other words: it is not your recently consumed meal that comes right back out again, but your intestines making room by moving some 'old stock'.

Confirmed by medical sources

The NHS website confirms this statement and states that the gastrocolic reflex is a completely normal reaction of the digestive system. It mainly occurs after a large or fatty meal and is more pronounced in some people than in others.

What can you do if it is bothersome?

For people who regularly suffer from this, Dr. Salhab recommends trying a Low FODMAP diet. This diet, which is often used for Irritable Bowel Syndrome (IBS) and SIBO (Small Intestinal Bacterial Overgrowth), helps to identify foods that can trigger digestive problems.

Foods that are temporarily avoided in this diet include garlic, onions, asparagus, cabbage, mushrooms, apples, avocados and certain dairy products such as milk and yogurt. After a few weeks, these products can be carefully reintroduced to test how the body reacts to them.

Conclusion

Do you also often have to go to the toilet immediately after eating? Then your digestive system is simply working properly. Your body efficiently regulates the flow of food and waste. However, if this causes too much inconvenience, adjusting your diet may provide relief. Either way, your intestines know exactly what they are doing!
