English / For International Patients

We specialize in acupuncture treatments for autonomic nervous system conditions, with a primary focus on Functional Dyspepsia (FD). Through our daily clinical practice in Nagoya, Japan, we see many patients who struggle in isolation, finding it difficult to gain understanding from their families, friends, or colleagues regarding their condition.

In our clinical experience, we have learned that FD cannot be addressed by focusing solely on the stomach. We believe the Gut-Brain Axis plays an profoundly important role in this condition.

While my practice is based here in Japan, I have decided to share these insights with the international community to help spread understanding of FD. I have accumulated valuable clinical data over many years and hope that by sharing it here, I can be of help to those around the world who are fighting this condition alone.

Many people suffering from functional dyspepsia (FD) share similar anxieties: “I was told my endoscopy was normal, yet I still feel so unwell.” “Even with medication, my symptoms don’t seem to improve.”

When faced with this, it is helpful to understand the concept of “somatization.” While it may sound like a complex term, it does not mean your symptoms are “all in your head” or that you are “overthinking.” Somatization simply refers to the process where the brain’s reactions to stress, anxiety, and tension manifest as real, physical symptoms in the body.

Our bodies do not function with the mind and body separated. When we experience high levels of stress, it can trigger changes such as:

• Shallow breathing

• Neck and shoulder stiffness

• Stomach pain

• Loss of appetite

These are not “in your head”; they are real, physiological changes in your autonomic nervous system, hormones, and muscle tension. In the case of functional dyspepsia, the brain’s stress response can directly impact how your stomach functions.

Functional dyspepsia is characterized by persistent symptoms like bloating, nausea, early satiety, and discomfort or pain in the upper abdomen. However, standard tests like endoscopies often reveal no major abnormalities. This can lead to anxiety, with patients wondering, “Is there something seriously wrong with my stomach?” or “Is there a disease that has been missed?”

In recent years, attention has shifted toward the “Gut-Brain Axis”—the profound connection between the brain, the stomach, and the intestines.

When we feel anxious or stressed, our sympathetic nervous system becomes dominant. This can lead to:

• Shallower breathing

• Tension in the diaphragm

• Stiffness around the back and the upper abdomen

• Decreased gastric motility (stomach movement)

Furthermore, the stomach may become less flexible, or the nerves in the stomach may become hypersensitive, making even minor stimulation feel painful or uncomfortable. Consequently, a vicious cycle is created: Anxiety → Autonomic Nervous System Tension → Worsening Stomach Symptoms.

A common experience for those with FD is “anticipatory anxiety”—for example, worrying: “What if I feel nauseous again?” or “Will eating out make my symptoms worse?”
The brain triggers a stress response simply by predicting a “potential danger,” even if no real danger exists at that moment. This causes the autonomic nervous system to tighten, reducing stomach function and making symptoms feel more intense. In other words, the anxiety itself can amplify the physical symptoms.

Understanding the concept of somatization allows you to move from thinking “My symptoms mean I have a serious illness” to realizing “My nervous system may be in a state of hypersensitivity.” This shift can reduce the fear surrounding your symptoms, which in turn can help lower physical tension. At our clinic, many patients have told us, “Understanding what is happening in my body has brought me peace of mind.”

Many people with FD share personality traits such as being patient, having a strong sense of responsibility, prioritizing others, or pushing themselves too hard. While not true for everyone, sometimes stress that should have been released manifests as physical symptoms. Recognizing that you have been “actually exhausted,” “pushing yourself,” or “unable to truly rest” can be a key turning point in your recovery.

Of course, stress is not the only cause of functional dyspepsia. Various factors, including reduced gastric motility, visceral hypersensitivity, sleep deprivation, and diet, are all involved. This is why it is essential to take a comprehensive approach:

• Monitoring stomach conditions

• Regulating the autonomic nervous system

• Getting adequate rest

• Cultivating a sense of safety and calm

Functional dyspepsia is not just a stomach issue; it is often linked to the brain, the autonomic nervous system, and your body’s stress response. Somatization is not about symptoms being “all in your head”—it is a concept that helps us understand how deeply our brains and bodies are connected. Instead of focusing only on your symptoms, understanding your body’s current state may be the first step toward recovery.
