Why do you get a stomach ache when you're nervous?

1. A Common Yet Hard-to-Explain Experience

Have you ever had an experience like this?

Suddenly experiencing a sharp, stinging stomach pain before an important presentation… Or the memory of urgently needing to use the restroom in an interview waiting room.

Some people even find their lower abdomen cramping up just by seeing their company's sign on the way to work. In such moments, most people simply dismiss it as, "I must be very nervous." However, this isn't merely a matter of personality or mental state. It's actually a highly sophisticated nervous system within our bodies reacting.

2. The Gut Reacts First – Rapid Autonomic Nervous System Involvement

When we experience tension, the 'autonomic nervous system' is the first to react. Specifically, the sympathetic nervous system activates, causing the heart to speed up, muscles to tense, and the intestines to begin contracting. This is a very primitive survival response, aimed at lightening the body in dangerous situations to facilitate escape. Thus, the gut initiates movements to empty itself, which directly leads to abdominal pain or diarrhea. This is commonly referred to as stress-induced bowel symptoms, but it is actually underpinned by quite sophisticated neurophysiological processes.

3. The Gut: Our Second Brain – An Overly Responsive Organ

Many people probably know by now that the gut contains over 100 million nerve cells. As such, this emotion-sensitive organ is sometimes referred to as the 'second brain'. Especially for those who frequently experience anxiety or are often in a state of heightened sensitivity, this intestinal nerve network is often 'hypersensitized'. Even a small stimulus can cause the gut to react immediately, sending signals like "my stomach hurts" or "I need to go to the bathroom." It's more accurate to view this not as a weak stomach, but as a condition where the neural circuits have become overly sensitive.

4. Anxiety Disorders and the Gut – The Link Between Emotions and Bowel Symptoms

In fact, gut symptoms are very common in mental health conditions such as generalized anxiety disorder, panic disorder, and even obsessive-compulsive disorder. Did you know that about 90% of serotonin is produced in our gut? Serotonin is a substance that influences not only mood regulation but also gut motility. So, when emotions fluctuate, the gut also fluctuates. The reverse is also true; if the gut remains uncomfortable, the brain perceives anxiety more intensely. This is the interconnected structure known as the brain-gut axis.

5. Anxiolytics? The Dilemma of Short-Term Prescriptions

Many people who seek treatment for these symptoms at an internal medicine clinic often receive a diagnosis of 'Irritable Bowel Syndrome' along with an anxiolytic prescription. The most common examples are medications like Depas (Etizolam) and Alprazolam. The problem is that most patients are unaware that these drugs are psychotropic medications. These medications do alleviate gut symptoms by suppressing the nervous system. However, long-term use is very dangerous because they suppress the central nervous system and can lead to dependence. This is literally a way to suppress symptoms and quiet them down, not a treatment that restores the body's functions.

6. Non-Psychotropic Treatment – An Approach Focused on Autonomic Nervous System Recovery

Therefore, in Korean traditional medicine, we prioritize non-psychotropic interventions. From a Korean traditional medicine perspective, it could be a state of intestinal tension due to Liver Qi Stagnation, a case where the mind is anxious and the intestines are weakened due to Spleen and Heart Qi Deficiency, or a condition where the digestive system itself lacks vital energy, leading to Spleen Deficiency Diarrhea. In such cases, based on the pattern differentiation, it is much safer and more effective to regulate intestinal nerve stimulation with acupuncture, balance the gut-heart system with herbal medicine, and retrain the autonomic nervous system through methods like diaphragmatic breathing, "crocodile breathing," and abdominal warm compress therapy. Diaphragmatic breathing, in particular, also has the effect of directly massaging the intestines. It's not just breathing like meditation, but a method that gently stimulates the entire internal organs by pushing the diaphragm downwards.

7. The Gut Speaks First

Everyone, the gut is not just a digestive organ. It's an emotion-sensing organ that first expresses the tension, stress, and emotional fluctuations our bodies experience. So, "stomach ache when nervous" might not mean something is wrong with your body, but rather that it's reacting too sensitively. In such cases, instead of suppressing symptoms with medication, looking back to "why this reaction occurred" and creating space for the body and mind to recover – that is the true beginning of treatment.
