Stomachache nausea vomiting is what symptom

Stomach pain refers to stomachache, nausea and vomiting may be caused by acute gastroenteritis, gastric ulcer, gastric cancer and other reasons.

1. Acute gastroenteritis

may be caused by unclean diet, ingestion of toxins and microorganisms. Toxins and microorganisms may invade the gastrointestinal mucosa, causing acute inflammatory reaction, leading to congestion and edema of the gastrointestinal mucosa, gastrointestinal smooth muscle spasm, so nausea and vomiting symptoms will occur.

2. Gastric ulcer

due to the formation of ulcers in the inner wall of the stomach or even deeper layers, will affect the digestive function of the stomach, leading to gastric motility slowing down, so patients are prone to indigestion, food will accumulate in the stomach after eating, causing nausea and vomiting symptoms.

3. Gastric cancer

If gastric cancer invades the pylorus, resulting in pyloric obstruction, gastric contents will be blocked from entering the intestinal tract, so gastric contents will accumulate in the stomach leading to gastric dilatation, causing nausea and vomiting symptoms.
