Hiccups are not necessarily a sign of a bad stomach. Hiccups are a sign of insufficient gastric power and indigestion, and there are many reasons for hiccups, including physiological and pathological ones. The most important thing is that you can get a good idea of what you’re doing. The symptoms of hiccups can also be seen in early pregnancy reactions, such as nausea, vomiting and late pregnancy when the fetus increases and the uterine cavity moves upward, directly against the stomach, reducing its capacity and indirectly affecting its digestive function. Pathological: Stomach diseases such as inflammation, ulcers and tumors can cause hiccups. If hiccups are frequent and are not relieved by improved eating habits, gastroscopy can be done to clarify the specific cause.
