Abdominal discomfort and nausea at night

Stomach discomfort and nausea at night are usually caused by improper diet, gastritis, gastric ulcers, or other reasons. Targeted treatment should be based on the specific cause. Detailed analysis is as follows:

1. Improper Diet

Eating large amounts of high-protein and high-fat foods during dinner, combined with overeating, can easily increase the burden on the gastrointestinal tract. After falling asleep, intestinal peristalsis slows down, leading to incomplete digestion and absorption. Food accumulates in the intestines, stimulating the gut and causing symptoms such as nighttime nausea and vomiting. Symptoms typically improve after adjusting eating habits and generally do not require special treatment.

2. Gastritis

Gastritis is an inflammatory condition affecting the gastric mucosa. Local inflammation stimulates excessive gastric acid secretion, resulting in nighttime nausea, upper abdominal discomfort, and regurgitation. Patients should take medications such as omeprazole enteric-coated capsules and metronidazole tablets under medical guidance.

3. Gastric Ulcer

In patients with gastric ulcers, ulcerative lesions form on the surface of the gastric mucosa. At night, gastric acid irritates the ulcer site, causing nausea along with stomach pain, acid reflux, and belching. Patients should follow medical advice and take medications such as ilaprazole enteric-coated tablets and aluminum magnesium hydroxide suspension for treatment.

Besides the common causes mentioned above, other conditions such as cholecystitis, pancreatitis, or duodenal ulcers may also be responsible. In such cases, patients should seek timely medical attention to avoid delaying treatment. During recovery, a light diet is recommended to reduce irritation to the gastrointestinal tract.
