Drinking cola can lead to flatulence, and it is recommended to drink less cola if you have poor stomach function. Coke is a carbonated beverage, which is rich in carbon dioxide. After drinking Coke, carbon dioxide enters the body and stimulates the mucous membrane of the gastrointestinal tract, which can easily cause flatulence. Normal people who drink Coke may have gas and bloating, and people with poor stomach function will also have gas and bloating after drinking Coke. Drinking cola with poor stomach function is not only prone to flatulence, but may also cause vomiting, nausea, acid reflux and other stomach discomfort symptoms, so patients with poor stomach function should drink less cola. When the stomach is bloated and uncomfortable after drinking cola with poor gastric function, you can massage the abdomen appropriately or take medicines to promote gastric power such as domperidone to relieve the symptoms. The medication should be directed by a doctor. When the stomach is not functioning well and the bloating after drinking cola is particularly difficult, you can also go to the regular hospital in time.
