According to a report on WebMD, gas, bloating, and bathroom problems are a constant battle for many people -- often the symptoms are related to diet, but there are some more serious medical conditions that may be the culprit.
Foods like beans, broccoli, and onions can cause gas, but what most people don't suspect are fruits, sodas, and milk. Fructose (a sugar found in fruits and sodas) and lactose (a sugar found in dairy products) are common causes of gas, bloating, abdominal cramps, and diarrhea, reports WebMD.
Lactose intolerance is extremely common. Fructose intolerance is also common, but less recognized, said the WebMD report.
Experts suggest that you keep a diary of foods that you eat and their relation to your symptoms and take that information to your doctor. Careful review of diet and the amount of gas passed may help relate specific foods to symptoms and determine the severity of the problem.
In addition, there are tests your doctor can perform to diagnose lactose and fructose intolerance. In fact, because of how common it is, Beyer suggests that people with these symptoms should get breath tests to see if fructose is the root cause of the problem.
