The human body is a powerful machine with a complex system to digest and absorb nutrients. As we push our bodies for any number of activities, the stomach and all surrounding organs come under stress. The more strenuous and length of activity the more likely you’ll face some level of GI Distress.
But the problem lies in how we fuel up. The stomach can only process so much nutrition over a period of time. And when you try and stuff too any nutrients in your body before a race or workout, the result can lead to what many athletes refer to as “bubble gut”. As any number of external factors increase like temperature, increased breathing and need for oxygen over longer periods of time like during an Ironman, Marathon or even Mountain Biking, the body has a hard time breaking down and processing everything that has been sent down.
