Gastric neurosis, also known as functional gastric disorder, is a common psychosomatic gastrointestinal condition triggered primarily by excessive mental stress and psychological trauma. Characteristically, patients present persistent gastric discomfort and pain with no organic pathological lesions detected in the stomach, confirming its functional and stress-mediated nature.
Gastrointestinal motility and secretory functions are regulated by the autonomic nervous system, relying on a dynamic balance between the sympathetic and parasympathetic nerves. Neurotransmitters, hormones, and digestive juices jointly maintain normal gastric peristalsis, blood vessel dilation, and metabolic stability. When psychological stress, emotional fluctuations, or acute stressors disrupt this neurological balance, gastric secretion, intestinal motility, and vascular vasomotor functions become dysfunctional. This imbalance leads to a wide range of clinical symptoms, including epigastric pain, belching, acid regurgitation, anorexia, heartburn, nausea, vomiting, postprandial fullness, and gastric spasmodic pain. Symptoms may occur independently or mildly in combination, with non-organic stomach pain being the most prevalent clinical manifestation.
Clinical Diagnostic Manifestations
Gastric neurosis presents diverse clinical symptoms, mainly categorized into four typical functional disorders, with inconsistent symptoms and physical signs and negative organic examination results.
1. Nervous Belching (Aerophagia)
Patients experience recurrent and persistent belching, attempting to relieve subjective abdominal distension and fullness by expelling perceived gastric gas. Systemic physical conditions remain generally normal. Paradoxically, frequent forced belching continuously swallows excessive air into the gastrointestinal tract, worsening abdominal distension and triggering a vicious cycle of intensified belching and gastric discomfort.
2. Nervous Vomiting
This condition predominantly affects female patients. Vomiting occurs immediately after food intake, usually without preceding nausea. The vomiting is effortless, with small vomit volume, and does not affect normal eating habits. Patients can resume eating right after vomiting without significant weight loss. Clinical symptoms are often inconsistent with physical examination findings, and symptoms can be effectively relieved through psychological suggestion and sedative intervention.
3. Nervous Anorexia
Loss of appetite is a core symptom of gastric neurosis, though patients rarely actively complain of this issue. Some patients develop extreme emaciation and even nutritional edema, yet maintain normal physical vitality, which contrasts sharply with cachexic appearance. Detailed medical history inquiry typically identifies underlying psychological triggers, such as excessive anxiety about body weight and obsessive weight-loss behaviors.
4. Nervous Gastric Motility Disorder
Caused by spasms of the cardia, pylorus, or gastric body, this disorder manifests as dysphagia, substernal distending pain, and severe epigastric cramping, which usually develops after gastric emptying.
In addition to the four typical symptoms, patients may experience substernal discomfort and postprandial heartburn, which worsen significantly in supine and forward bending positions. Although antacids can provide temporary relief, symptoms tend to recur periodically. Other common manifestations include persistent upper abdominal discomfort, nausea, early satiety, and unfixed epigastric pain that typically alleviates during nighttime rest.
Clinically, gastric neurosis is defined by numerous somatic symptoms with minimal physical signs. Severe anorexic patients may develop cachexia, systemic edema, sparse axillary and pubic hair, decreased basal metabolic rate, and hypotension. Patients with gastric motility disorders may present mild abdominal tenderness without rebound tenderness, while neurological examinations show completely normal results. All laboratory and auxiliary imaging tests exclude organic gastrointestinal lesions.
Standard Acupuncture Treatment for Gastric Neurosis
Acupuncture for gastric neurosis is a targeted, non-invasive TCM therapy for functional gastrointestinal disorders. It regulates autonomic nerve balance, improves gastric motility, relieves visceral nerve spasm, and eliminates stress-induced gastric symptoms without pharmaceutical side effects.
Standard Acupoints & Needling Specification (WHO Standard)
1. Jiuwei (CV15)
Location: On the anterior midline of the abdomen, approximately 15 mm below the xiphoid process and 175 mm above the umbilicus.
Needling Method: Use a 30-gauge, 3.5-inch filiform needle. After routine aseptic disinfection, insert the needle downward at a 25° angle to the skin to a depth of 85 mm.
Needling Sensation: Local epigastric distension and soreness.
2. Zhongwan (CV12)
Location: On the anterior midline of the abdomen, approximately 100 mm above the umbilicus.
Needling Method: Use a 30-gauge, 2-inch filiform needle. After standard disinfection, perform perpendicular insertion to a depth of 40 mm.
Needling Sensation: Local abdominal distension and soreness.
3. Zusanli (ST36, Bilateral)
Location: Approximately 75 mm below Dubi (ST35), one finger breadth lateral to the anterior crest of the tibia.
Needling Method: Use two 30-gauge, 2-inch filiform needles. After local aseptic disinfection, insert perpendicularly to a depth of 45 mm.
Needling Sensation: Local calf distension and soreness, or radiating tingling sensation extending toward the dorsum of the foot.
Clinical Treatment Protocol
Patients lie in a supine position during treatment. All acupoints are needled in accordance with standardized aseptic operating procedures. Needles are retained for 60 minutes per session without manual manipulation after insertion. After needle withdrawal, cupping therapy is applied locally for approximately 1 minute to promote qi and blood circulation.
Treatment is performed once daily. A full therapeutic course consists of 6 consecutive sessions, with a 3-day rest interval before starting the next course.
Clinical Discussion & Therapeutic Notes
After excluding organic gastrointestinal diseases, standardized acupuncture therapy delivers remarkable and stable efficacy for gastric neurosis. Psychological intervention is essential during treatment: comforting patients and relieving underlying mental anxiety can significantly amplify acupuncture therapeutic effects.
After clinical recovery, patients are advised to strengthen physical exercise, regulate mental and emotional state, and maintain a positive mood to reduce symptom recurrence. Long-term physical and psychological conditioning effectively prevents recurrent functional gastric disorders.
