Gastric spiciness, i.e. burning sensation in the stomach with hiccups, may be related to reflux esophagitis, gastritis, peptic ulcer and other disease factors, or may be caused by eating spicy and stimulating foods. 1. Reflux esophagitis: the burning sensation in the stomach is mainly considered to be caused by increased secretion of gastric acid, which can be characterized by hiccups, acid reflux, burning sensation and other manifestations. 2. Gastritis: patients with gastritis may have bloating, hiccups, heartburn and other manifestations. 3. Peptic ulcer: when the gastric mucosa of peptic ulcer is broken, the gastric acid secretion increases, which can cause irritation to the mucosa of the stomach, resulting in hiccups and burning sensation in the stomach. Eating spicy and irritating foods such as chili peppers can also cause these symptoms. If you have an upset stomach, seek medical attention as soon as possible and do not take medication on your own to avoid delaying your condition.
