Gallbladder stones may cause bloating. However, bloating can also be due to other reasons, and there are many causes of bloating, such as decreased gastrointestinal motility and decreased pancreatic function. The details are as follows. 1. Gallbladder stones: The main components of bile are cholesterol, bile salts, bile acids, bile pigments, etc. Cholesterol and bile salts can promote the digestion and absorption of fat. When there are stones, it leads to abnormal bile secretion function, fat and other substances can not be completely digested, then nausea, vomiting, abdominal distension and other manifestations may occur. 2. Decreased gastrointestinal motility: lack of exercise, sedentary lifestyle and other reasons can slow down gastric emptying and poor intestinal peristalsis, resulting in a large amount of food gathering in the digestive tract, causing abdominal discomfort and bloating. 3. Decrease in pancreatic function: pancreas can secrete a lot of digestive enzymes such as trypsin and pancreatic lipase, when pancreas is damaged or pancreatic atrophy, the secretion function decreases, and the fat, protein and other substances can not be digested normally, and the bloating performance will occur. In addition, gastritis, enteritis, etc. can also lead to abdominal distension, so when patients find abdominal distension, it is recommended to go to the regular hospital for abdominal ultrasound, gastroenteroscopy and other related examinations, early detection of the cause of the disease, timely treatment, so as not to miss the condition.
