Introduction

1. Overeating—such as eating too quickly or excessively, consuming very hot or very cold foods and beverages, or drinking alcohol. 2. Gastric disorders—persistent belching is often caused by underlying gastric conditions; frequent burping or belching—even when fasting—may occur involuntarily. 3. Excessive stress—when under significant mental stress, the body’s demand for oxygen increases.

Frequent hiccups may result from diaphragmatic spasm or could be caused by certain gastric disorders, such as indigestion, gastric ulcers, duodenal ulcers, or chronic gastritis. If hiccups occur regularly, it is advisable to undergo gastroscopy at a hospital to identify the underlying cause and receive appropriate treatment. So, what causes persistent hiccups? Below, we address this question.

Causes of Persistent Hiccups

1. Overeating

Eating too quickly or excessively, consuming extremely hot or cold foods or beverages, alcohol consumption, sudden changes in ambient temperature, and excessive smoking may all contribute to hiccups. Hiccups occurring frequently or lasting longer than 24 hours are termed “intractable hiccups” and often signal an underlying medical condition—prompt medical evaluation is recommended. Additionally, nerve damage within the body can trigger hiccups; while some individuals experience only brief episodes, others suffer prolonged ones. In most cases, such nerve injury results from trauma or tumors.

2. Gastric Disorders

Persistent hiccups may stem from gastric disease. Frequent belching or hiccups—even when fasting—may indicate Helicobacter pylori infection and consequent gastritis. Prompt medical consultation is advised for confirmation via gastroscopy, blood tests, and other diagnostic evaluations. If persistent hiccups remain unexplained, timely hospital evaluation is strongly recommended.

3. Excessive Stress

During periods of heightened psychological stress, the body’s oxygen demand increases, prompting mouth breathing. This leads to excessive air intake, potentially triggering hiccups. Similarly, acute anxiety—such as before examinations or competitions—can induce a sensation of hypoxia due to intense emotional tension, causing involuntary mouth opening and air inhalation, thereby provoking hiccups.

The above outlines the primary causes of persistent hiccups. We hope this information proves helpful.

What Causes Persistent Hiccups?

Hiccups, clinically referred to as “singultus,” involve involuntary, repetitive contractions of the diaphragm. Occasional or brief episodes—such as one or two hiccups—are generally harmless and require no intervention. However, persistent or intractable hiccups warrant further evaluation and management tailored to the individual patient’s condition. Potential causes include ingestion of cold or raw foods, tumor-related irritation or compression of the diaphragm or its innervating nerves, and psychological factors such as anxiety or depression, which may trigger functional (idiopathic) hiccups.
