What causes a burning sensation in the stomach?

Here are some potential causes of stomach burning sensations:

1. Gastroesophageal reflux disease (GERD): This is one of the most common causes. When the contents of the stomach and duodenum abnormally reflux into the esophagus, it can cause heartburn, chest pain, and other symptoms.

2. Dietary factors: Excessive alcohol consumption, caffeine, spicy foods, high-fat foods, and similar items can stimulate gastric acid secretion and increase the risk of heartburn.

3. Obesity: Excess abdominal fat increases intra-abdominal pressure, promoting the reflux of stomach acid.

4. Smoking: Nicotine in tobacco relaxes the lower esophageal sphincter, making it easier for stomach acid to reflux.

5. Medications: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin, and some antibiotics, may irritate the gastric mucosa and cause heartburn.

6. Stress and anxiety: Although not a direct cause, stressful and anxious states may exacerbate symptoms of heartburn.

If a burning sensation in the stomach persists or fails to improve, it is recommended to seek medical attention promptly. A physician may develop a personalized treatment plan based on the patient's specific condition to alleviate symptoms and improve the condition.
