Nausea, dryness and hiccups are related to chronic gastritis, indigestion, gastrointestinal dysfunction, pregnancy and other factors. Chronic gastritis, after long-term illness, not only makes the gastric mucosa more susceptible to the stimulation of gastric acid, but also causes the digestive function to be affected, especially when the food in the stomach produces a large amount of gas after poor fermentation, leading to excessive gastric pressure, which then causes nausea, dry vomiting and burping. When indigestion exists in the human body, the emptying time of food is relatively prolonged, and the stomach lining becomes too dilated when large amounts of food are ingested. Some people may also experience spasmodic contraction of the stomach as a result, which can cause irritation to the diaphragm, thus causing the manifestation of stomach discomfort. Gastrointestinal dysfunction is related to bad emotions, improper diet, etc. The peristalsis of the stomach and intestines will be abnormal at the onset, and some people may even show a peristaltic movement, which will lead to nausea, dry vomiting and hiccups. During pregnancy, the endocrine system of a woman’s body may become disturbed, leading to symptoms in the gastrointestinal system, especially nausea and dry vomiting in the morning when she wakes up. Some women may also experience hiccups due to diaphragm irritation.
