After a tremendous amount of research, thinking and personal experimentation, I realized that my digestive was NOT diseased but STRAINED. As mentioned above, my digestive system was struggling to digest the foods I was eating and the fluids I was drinking. How did I know it was struggling? Because of the diarrhea, bloating, stomach pain, constipation, etc...
This is why doctors and experts alike can only diagnose IBS after they have eliminated all other digestive diseases and disorders - because the digestive system is not diseased, but simply strained!! How can they diagnose a strained digestive system?
