One concern I often hear in the clinic is, “My endoscopy was fine, but whenever I eat, I quickly feel blocked and bloated.” If you feel full after eating only a small amount, have tightness in the upper abdomen, and continue to belch or feel nauseated, eating itself can become burdensome. Even when tests do not show clear inflammation or ulcers, these discomforts can last if the stomach’s ability to receive food and move it downward has weakened.
Why does functional dyspepsia occur?
Functional dyspepsia refers to a condition in which upper abdominal discomfort recurs even though there is no clear structural lesion. Early satiety, post-meal bloating, epigastric pain, heartburn, frequent belching, and nausea may occur together. Reduced activity, irregular meals, greasy or irritating foods, stress, and lack of sleep are common factors that disrupt the stomach’s rhythm.
The key is the rhythm of stomach movement
The stomach is not simply a pouch where food stays; it contracts and relaxes according to a regular electrical rhythm. When this rhythm is unstable, food may remain for a long time, or the pressure inside the stomach may be felt more sensitively, causing a full feeling even after eating only a little. In Korean medicine, this is viewed as a state in which the spleen-stomach’s transformative and transportive function is weakened and the flow of qi is blocked, and the approach differs according to constitution and symptom pattern.
Electrogastrography can help assess function
Endoscopy is important for checking inflammation, ulcers, tumors, and other mucosal findings, but it does not show all aspects of the stomach’s motility rhythm. Electrogastrography is a test that attaches electrodes to the abdominal skin to measure electrical signals generated by the stomach and examine the regularity and abnormal patterns of gastric movement. It can be used as a reference when delayed gastric emptying or gastroparesis is suspected, or to check fast and irregular rhythms such as gastric tachyarrhythmia.
Korean medicine treatment is adjusted to your condition
In treating functional dyspepsia, I first look at meal amount, eating speed, stool condition, weight changes, and stress response together. Herbal medicine is formulated to support gastrointestinal movement and reduce upper abdominal tension, nausea, and bloating, but it varies depending on whether the stomach feels cold or there is more heat, and whether constipation or diarrhea is present. Studies in patients with functional dyspepsia have reported improvement in early satiety and a decrease in abnormal rhythms on electrogastrography after Korean medicine treatment, so in clinical care, I use these functional assessments as a reference in setting the treatment direction.
When Lifestyle Management and Consultation are needed
- It is better to eat regularly and chew slowly rather than eating a large amount at once.
- During periods when symptoms are severe, try reducing late-night meals, excessive alcohol, too much caffeine, and greasy delivery foods.
- Avoid lying down right after meals, and support gastric emptying with a light walk.
- If you have unexplained weight loss, black stools, vomiting blood, difficulty swallowing, or severe abdominal pain, we recommend seeking medical care.
- Do not stop any stomach medications or other medications you are taking on your own; discuss adjustments with your Medical Team.
When indigestion lasts a long time, food intake decreases and energy drops, which can again weaken stomach function and create a vicious cycle. Rather than seeing it only as a stomach acid issue, it is easier to find clues for management by looking together at how your stomach moves and which lifestyle patterns make it unstable. If bloating and early satiety keep recurring, please consider care suited to your condition and take steady steps toward recovery.
