Gastric distress (epigastric discomfort) burping (belching) and nausea and vomiting are common indigestion symptoms, the causes of which are divided into functional and organic diseases. The causes of dyspepsia symptoms are classified as organic and functional. Functional dyspepsia refers to the presence of belching, stomach pain, bloating, and early satiety in patients without clear structural and blood abnormalities. These symptoms are aggravated before and after meals and affect the patient’s life and emotional health, but the pain level is usually not too severe to wake up in pain during sleep. Many people have poor sleep, depression or anxiety, which affects eating and even work. The quality of life is poor and symptoms can recur. Stomach pain with hiccups can likewise occur in organic diseases, such as peptic ulcer disease, gastroesophageal reflux disease, and even oncological diseases. Other systemic diseases, such as diabetes mellitus, can also present this symptom. And gallbladder disease, pancreatic disease and even colon disease are also possible to have similar symptoms. If the stomach pain is accompanied by vomiting, emaciation, blood in stool, anemia, fever and other manifestations, and the pain wakes up at night, and the pain seriously affects sleep, it suggests that organic diseases are more likely, and it is recommended to see a doctor as soon as possible to do relevant tests to exclude organic diseases. Especially for people over 40 years old, gastroscopy and other related examinations should be done promptly.
