What causes a warm or hot sensation in the stomach?

The term "stomach" usually refers to the abdominal area. A warm or hot sensation in the abdomen may be caused by improper diet, intense physical exercise, indigestion, acute gastroenteritis, gastric ulcers, and other conditions. If discomfort occurs, it is recommended to seek medical attention promptly. The specific causes are analyzed as follows:

1. Improper Diet

After consuming spicy or greasy foods, gastrointestinal digestive activity increases and produces more heat, which may lead to a warm or hot feeling in the abdomen. It is advisable to adjust dietary habits by reducing intake of spicy and oily foods and eating more light, easily digestible meals.

2. After Intense Exercise

Following vigorous physical activity, the body's metabolic rate increases and generates more heat, potentially causing a warm sensation in the abdomen. Rest appropriately and replenish fluids and electrolytes to help restore the body’s balance.

3. Indigestion

Long-term overeating or irregular eating patterns may cause food to accumulate in the gastrointestinal tract without being digested in time, leading to a burning sensation. Abdominal massage can be performed to enhance gastrointestinal motility.

4. Acute Gastroenteritis

Acute gastroenteritis is often associated with viral or bacterial infections, which trigger inflammatory responses in the gastrointestinal tract and result in a burning sensation in the abdomen. Symptoms may include high fever and chills. It is recommended to take medications such as compound berberine tablets, smectite powder, or loperamide hydrochloride capsules under a doctor’s guidance.

5. Gastric Ulcer

Gastric ulcers are commonly linked to factors such as Helicobacter pylori infection and poor dietary habits. Under bacterial irritation, ulcers and erosion develop in the gastric mucosa, triggering a burning sensation in the abdomen. Additional symptoms may include nausea and vomiting. Patients may take medications such as lansoprazole enteric-coated tablets, hydrotalcite tablets, or metronidazole tablets under medical supervision.

In daily life, one should avoid excessively spicy or greasy foods, drink adequate water to maintain fluid balance, and refrain from eating immediately after intense physical activity.
