Carbonated water is used in flavored soft drinks but can also be enjoyed on its own. Most people enjoy it without problems; However, according to the University of Maryland Medical Center, carbonated drinks can irritate the stomach and intestinal wall, which can cause some irritating side effects, and these side effects can lead to problems with digestion, and can even be confused with more serious diseases.
As the water bubbles with carbonic acid and blisters in the stomach, it can lead to a build-up of air, and this can lead to loud belching. The burping can sometimes be uncontrollable. This accumulation of air can also cause flatulence. If enough water is consumed with carbonic acid, you may suffer from painful, chronic flatulence. The pain of flatulence may even be falsely related to other disorders such as drowsiness, and you may even feel the need to seek medical help.
Carbonated beverages can cause an overproduction of stomach acid, which can irritate the gastric mucosa and cause a stomach ulcer. According to the University of Maryland Medical Center, gastric ulcers are open wounds in the gastric mucosa, the esophagus or the first part of the intestine, also called the twelve-finger gut. This can cause considerable pain and even lead to bleeding in the stomach. Some people also vomit blood or black stool caused by the bleeding in the stomach. This condition requires immediate medical treatment.
Carbonated water can cause a build-up of air that can move down the digestive tract and into the colon and cause flatulence. According to the University of Maryland Medical Center, a safe way to avoid flatulence is to avoid carbonated drinks all together.
