What could be causing a slightly nauseous feeling in the stomach?

A slight feeling of nausea in the stomach may be caused by improper diet, indigestion, chronic gastritis, or other reasons. It is recommended to visit a hospital for professional evaluation and diagnosis to determine the specific underlying cause.

1. Improper Diet

Regular consumption of spicy, stimulating, raw, cold, or greasy foods, overeating, or consuming excessive and varied types of food may irritate the gastric mucosa, leading to a mild sensation of nausea in the stomach.

2. Indigestion

Indigestion can result from poor eating habits, long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), work-related stress, or poor sleep quality. This may cause a slight feeling of nausea in the stomach, as well as symptoms such as vomiting, belching, and loss of appetite.

3. Chronic Gastritis

Chronic gastritis often develops when the gastric mucosa suffers prolonged and repeated damage due to dietary factors, medications, or other causes. Additionally, infection with Helicobacter pylori may also lead to chronic gastritis, causing symptoms such as mild stomach nausea, epigastric discomfort, and bloating.
