Gas blockage in the chest always causes hiccups related to indigestion, gastritis, gastric ulcer, and over-excitement. Indigestion is related to the slow peristalsis of the stomach and the relatively low secretion of digestive juices, so the food in the stomach stays relatively longer and produces a lot of gas during bad fermentation. Gastritis and gastric ulcers are relatively common diseases of the stomach and are associated with damage to the gastric mucosa. Excessive acid secretion can cause irritation of the stomach lining and even spasm of the diaphragm, resulting in hiccups. The disease also affects gastric function, resulting in slow gastric motility and a feeling of stomach congestion. When the body becomes emotionally disturbed, the body suffers from a disturbance of the vegetative nerves, and some people may suffer from liver stagnation, resulting in chest congestion and hiccups.
