Why does the food come out undigested?

The presence of undigested food residues in the chair can have various causes and is not necessarily a reason to worry. Here are some possible reasons why this might occasionally occur:

1. Fast intestinal passage: Sometimes the food can run through the gastrointestinal tract faster than usual. This can occur if you eat, for example, large amounts of fiber that can accelerate the intestinal passage.
2. Bad chewing: Inadequate chewing can lead to larger pieces of food entering the intestine without being digested sufficiently.
3. Digestive disorders: digestive problems, such as reduced production of stomach acid or enzymes, can affect digestion and cause food to remain undigested.
4. Medicines: Some drugs can affect the digestion and cause food residues to be visible in the chair.
5. Stress or excitement: Emotional stress and stress can affect the digestion and cause food to pass through the digestive tract.

It is important to note that occasional occurrences of unfamiliar food residues in the chair are normally not a reason for concern. However, if this occurs repeatedly, accompanied by other symptoms such as abdominal pain, diarrhea, weight loss or persistent digestive problems, it is advisable to consult a doctor. A doctor may carry out further investigations to determine the exact cause and recommend appropriate measures.
