This vlave is where the small intestine meets the large intestine. If I recall, the Colonix plan requires something like 10g of a psyllium powder per day. This roughy converts into 3 tablespoons per day. Let's see now - 1 teaspoon of psyllium will create over 1 cup of stool - so 3 tablespoons will create about 10 cups of stool PER DAY. This 3 tablespoons of psyllium would have needed 10 cups of water per day to hydrate properly - this is 80 ounces of water - 80 ounces of water is 2.5 quarts.
So - she would have needed 2.5 quarts of water per day just for the hydration of the psyllium - and an additional 2 quarts of water per day for her body to function. If she was not drinking over 1 GALLON of water PER DAY - then the psyllium has balled up in her body creating a blockage.
She simply needs to drink water and fruit juices - eat soups and fruits and vegetables - until this blockage can be passed.
