Future is ready for swallowable sensors

You may have noticed that even just before the onset of a simple cold or a minor fever, disordered gut function may be experienced. In addition to coryzal symptoms and fever, abdominal discomfort or altered bowel function are not uncommon as accompanying symptoms, such as bloating, abdominal pain, nausea, vomiting, constipation or diarrhea. It is not surprising, as the gut walls are porous, allowing the absorption of nutrients from food intake. The gut mucosa very rapidly exchanges certain chemicals in body fluid compartments with gut liquid and gaseous contents. It is likely that imbalance of the body chemical contents, as a result of a health disorder, rapidly shows itself as changes in gut contents.
