Having had hiccups for over two years, but the gastroscopy showed nothing abnormal—what could be the reason?

Generally, hiccups refer to belching, a common physiological phenomenon caused by air entering the esophagus and stomach during swallowing. If belching persists for more than two years and no abnormalities are found during gastroscopy, it may be due to psychological factors, dietary habits, indigestion, or other causes. Specific analyses are as follows:

1. Psychological Factors

Stress, anxiety, fatigue, and excessive pressure can all trigger belching. Therefore, relaxation techniques and stress reduction methods may help alleviate hiccups.

2. Dietary Habits

Overeating, consuming carbonated beverages, eating too quickly, or excessive food intake may lead to belching. Adjusting food texture and eating habits can help reduce symptoms to some extent.

3. Indigestion

Disruption of intestinal flora can weaken digestive function, leading to indigestion. When food accumulates in the intestines, belching may occur. Under medical guidance, patients may take medications such as Jianwei Xiaoshi tablets or domperidone tablets for treatment.

In addition to the above common causes, belching could also result from gastroesophageal reflux, gastritis, or esophagitis. It is recommended to seek timely medical evaluation to identify the underlying cause and receive targeted treatment. In daily life, maintain healthy lifestyle habits and avoid spicy or irritating foods to promote recovery.
