My Grandfather was experiencing many stomach problems. He went to a specialist about the problem. The first thing the Doctor wanted to do was a colonoscopy test. After having the test done, he was still having the same problems and nothing showed up on the test. He then had to have a CT scan done on his complete stomach. Again, nothing showed up. The last and cheapest thing the Doctor advised him to do was try a product called colon cleanse. After doing this, all the pain and problems went away.
