Hello. This is Dalimchae Korean Medicine Clinic.
Why Does Acid Keep Coming Up? Uncomfortable Acid Reflux is Not Just Indigestion.
Do you experience a sour taste rising to your throat after meals or when lying down, or lose sleep due to burning pain in your chest? "Why does acid keep coming up?" is a question more and more people are bringing to the clinic. Many think it's just indigestion and take antacids, but the symptoms often return. This is because acid reflux can have deeper causes than just a simple stomach upset.
💡 [Key Answer] 3 common causes of acid reflux symptoms: ① Weakening of the lower esophageal sphincter function ② Increased intra-abdominal pressure (Damjeok, functional dyspepsia) ③ Autonomic dysfunction due to gut-brain axis imbalance Dalimchae Clinic helps restore gastrointestinal function and improve reflux symptoms through gut detox and autonomic stabilization treatments.
Is Acid Reflux Just an Acid Problem?
Many people believe that acid reflux and heartburn are caused solely by excess stomach acid. While acid excess can be a factor, the more fundamental problem lies in the weakened 'lower esophageal sphincter' and increased gastric pressure. The lower esophageal sphincter is a muscle at the junction of the esophagus and stomach that should stay closed to prevent acid from rising. When this muscle weakens, acid leaks back into the esophagus.
In Korean medicine, gastroesophageal reflux disease (GERD) is interpreted as a complex issue involving decreased gastric motility, accumulation of waste (Damjeok), and autonomic imbalance due to stress. 'Damjeok' refers to toxins and waste built up in the stomach wall that increase internal pressure. If symptoms persist despite a normal endoscopy, Damjeok syndrome is a likely cause.
The Connection Between Autonomic Nerves and Acid Reflux
The digestive system is governed by the autonomic nervous system. Stress is a major factor that disrupts gastric motility and acid secretion. Excessive stress activates the sympathetic nervous system, slowing down digestion and keeping food in the stomach longer, which increases the likelihood of reflux.
Recent studies support the effectiveness of herbal medicine for reflux symptoms. A study published in PubMed in February 2024 showed that herbal treatment significantly improved symptom evaluation indices (NRS, FSSG, GERDQ) in patients with reflux symptoms. Another meta-analysis from May 2025 demonstrated that combining herbal medicine with PPIs (proton pump inhibitors) showed positive additive effects on reducing heartburn and recurrence rates. These findings highlight the importance of Korean medical treatments that restore stomach function and balance the autonomic system.
Necessary Treatments for Persistent Reflux
Dalimchae Clinic focuses on gut detox to solve the root causes of chronic reflux. Gut detox breaks the cycle of toxins on the gut wall causing systemic inflammation and gastric dysfunction. By restoring the gut wall, normalizing peristalsis, and promoting enzyme secretion, we create a healthy digestive environment. This reduces gastric pressure and strengthens the esophageal sphincter.
Restoring autonomic balance is also crucial. We use customized herbal medicine to aid 'Qi' circulation and acupuncture/moxibustion to improve gastric meridian flow. This integrated approach aims for long-term health beyond just symptom relief.

- Burning pain/heartburn from the solar plexus to the chest.
- Feeling of a lump in the throat (Maehaekgi).
- Chronic cough, hoarseness, or sore throat.

Q. Can acid reflux heal naturally? A. Lifestyle changes help, but chronic cases require active treatment to prevent serious issues like esophageal stricture.
Q. How long is the treatment? A. It varies, but chronic cases involving Damjeok or autonomic imbalance require steady treatment and management for fundamental improvement.
Q. Can indigestion and reflux be treated together? A. Yes, since they often share common root causes like Damjeok or low gastric function.
