Stuffy stomach is associated with gastrointestinal dysfunction, indigestion, improper diet, liver depression and stagnation. People with normal gastrointestinal function, the food will be emptied quickly after entering the stomach, and at the same time, the intestines will absorb the nutrients. When gastrointestinal dysfunction occurs due to the relatively slow peristalsis of the stomach, so the food in the stomach can not be emptied in time, and a feeling of bloating in the stomach occurs. When intestinal dysfunction occurs, the intestinal tract is unable to absorb the gas in the intestinal lumen, resulting in intestinal flatulence.

This not only affects the function of the gastrointestinal digestive system, but also produces a large amount of gas during digestion, especially when consumed in excess, resulting in a feeling of flatulence. Many people have a feeling of bloating in the stomach when they have mood swings, which is directly related to liver stagnation and stagnation of qi.
