Carbonated water is used in flavored sodas, but can also enjoyed by itself. Most people enjoy it without any problems; however, according to the University of Maryland Medical Center, carbonated beverages can irritate the stomach and intestinal lining, which can cause some irritating side effects to occur, and these side effects can lead to problems with digestion, and can even be confused with more serious illnesses.

Belching and Bloating

As the carbonated water fizzes and bubbles in the stomach, it can cause a buildup of air, and this can lead to loud belching. This belching can sometimes become uncontrollable. This buildup of air can also cause abdominal distension, or bloating. If enough carbonated water is consumed, you can suffer from painful, chronic bloating. The pain from bloating can even be mistaken for other illnesses such as appendicitis, and you may even feel the need to seek medical help.


Carbonated beverages can cause an excess production of stomach acid, which can irritate the stomach lining and cause a peptic ulcer. According to the University of Maryland Medical Center, peptic ulcers are open sores in the stomach lining, esophagus or the first part of the intestine, also called the duodenum. This can cause significant pain and even lead to bleeding in the stomach. Some people also vomit blood or have black stools caused by the bleeding in the stomach. This condition requires immediate medical treatment.


Carbonated water can cause a buildup of air that can move down the digestive tract and into the colon, causing flatulence. According to the University of Maryland Medical Center, one sure way to avoid flatulence is to avoid carbonated beverages all together.
