THERE MIGHT BE SOMETHING WRONG with your inner tube, and it could be making you sick and fat. You may not even realize you have a problem … but if you have health concerns of any kind or if you are overweight, your inner tube could be the root cause. Of course, I’m not talking about a beach toy. I mean the inner tube of life – your digestive system! It is likely that you suffer from (or have suffered from) some type of digestive disorder – irritable bowel syndrome, bloating, constipation, diarrhea, heartburn, reflux, gas, and other things too gross to mention. And you are not alone. More than 100 million Americans have digestive problems.
