Introduction
Reflux of sour fluid may be caused by either cold in the stomach or excessive stomach heat; the specific type must be determined based on accompanying symptoms. Reflux due to stomach cold is usually caused by insufficient yang energy in the spleen and stomach, leading to failure to control gastric acid, which then rises upward. It is commonly accompanied by symptoms such as regurgitation of clear, sour fluid, cold pain in the stomach, preference for warmth and pressure, poor appetite, and worsening of symptoms after consuming raw or cold foods. The tongue coating is typically white and greasy.

Acid regurgitation can typically be caused by either cold stomach or stomach fire; the specific type should be determined based on accompanying symptoms. If in doubt, it is recommended to evaluate the overall clinical presentation for proper pattern differentiation and treatment. Detailed analysis is as follows:

Regurgitation due to cold stomach usually results from insufficient yang energy in the spleen and stomach, leading to unconstrained stomach acid rising upward. It is commonly accompanied by symptoms such as regurgitation of clear fluid, cold pain in the stomach region, preference for warmth and pressure, poor appetite, and worsening symptoms after consuming raw or cold foods. The tongue coating is often white and greasy.

Regurgitation caused by excessive stomach fire is often triggered by consumption of spicy foods or emotional imbalances, resulting in over-secretion of gastric acid and damage to the gastric mucosa. Common symptoms include acid reflux, heartburn, burning stomach pain, dry mouth, bitter taste, bad breath, and dry stools—signs of internal heat. The tongue coating is typically yellow and greasy.

In daily life, maintain regular eating habits and avoid irritants such as raw, cold, or spicy foods. Individuals with cold stomach may benefit from warming foods such as ginger and Chinese yam, while those with stomach fire may consume heat-clearing foods like mung beans and winter melon. If symptoms occur frequently or are accompanied by severe pain, seek medical attention promptly to identify the underlying cause.
