Stomach discomfort in the morning may be due to the food eaten the night before and gastrointestinal diseases, such as overeating, eating too fast, talking too much and laughing while eating, which can easily inhale a lot of gas and therefore cause abdominal distension, or eating too much gas-producing food, such as eating high starchy foods or too much meat, which are not easily digested and absorbed in the intestinal tract When bacteria break down these foods, they produce a lot of gas, which can cause bloating and discomfort. It is also considered that there may be a relationship with intestinal dysfunction and indigestion. If the intestinal flora is dysfunctional, abnormal fermentation in the intestine will occur, inducing symptoms of bloating, nausea, vomiting and abdominal pain, which may be acute gastroenteritis, gastric ulcer and other diseases, requiring timely diagnosis and treatment at the hospital.
