People whose stomach hurts when they get nervous — the gut and the autonomic nervous system

Some people get a stomachache or a sudden urge to go to the bathroom when they get nervous. It's not because they're oversensitive — it's because the gut and the autonomic nervous system are connected.

The movement and secretion of the digestive tract are handled by the parasympathetic nervous system. When tension makes the sympathetic nervous system dominant, blood flow and signals to the digestive tract decrease, so you feel bloated, or conversely your stomach suddenly hurts and you feel an urgent need to go.

  • Your stomach hurts before an exam, a presentation, or a meeting
  • When you're stressed, you can't digest or you get diarrhea

If this is your pattern, you need to look at the balance of the autonomic nervous system together with the stomach itself, rather than the stomach alone. Managing the gut becomes managing the tension.

A graduate of the College of Korean Medicine at Kyung Hee University, with master's and doctoral degrees in pathology — the mechanisms of disease — from its graduate school. Later served as a research professor in the university's Herbology department, studying medicinal substances. Studying both disease and medicine from both sides is the foundation of this practice: explaining "why a given medicine works for a given illness" in the language of both pathology and pharmacology. Explains autonomic, chronic, and intractable conditions — and structural problems of the body — in the language of modern science, and proposes treatment matched to the cause. Has taught prescribing and clinical practice to Korean medicine doctors for over ten years, and is a co-author of "Korean Medicine, Explained by Korean Medicine Doctors," selected for the 2018 Sejong Books list (general category).
