When the ICV becomes a problem, it can become spastic, where the valve will remain open. This is allowing the toxic waste that you should be eliminating to be back up into the small intestine. Your small intestine then begins to absorb these toxins, which leads to a number of symptoms.

When the ICV becomes stuck closed, the food you have digested is being stuck in your small intestine where your body then begins to absorb toxins also which leads to a number of symptoms because it cannot pass through to your large intestine.

If you (or someone you know) are experiencing any of these symptoms and cannot figure out what exactly is causing them to have headaches, fatigue, back pain, etc., seek out a practitioner that specializes in applied kinesiology.
