What causes mixed irritable bowel syndrome (IBS-M)?

ANSWER

Doctors don’t really know what causes the condition, which switches back and forth between diarrhea and constipation. It may happen for a number of reasons, which could be different from person to person. Some possible reasons behind it include:

  • Your genes
  • Infections
  • Inflammation
  • The way your brain and your digestive tract signal each other
  • Psychological factors, like stress or past trauma
  • Your diet
  • Gut bacteria
