That Gall bladder problem.....

The gall bladder is a storage tank for the digestive juices required to digest fats. It's a muscle that contracts when the body senses ingestion of fat. During long periods of no or very low-fat eating, of whatever type, the brain doesn't send the message to the gall bladder to contract. This causes the digestive juices to sit in the gall bladder and wait. And wait. And wait. (the amount of digestive juices produced also goes down, so there isn't a back-up, just stasis)

Stasis (fluid sitting anywhere in the body not going anywhere) causes...well...hardening. It's not just very low fat eating that can cause this. Any situation that results in the stasis of the fluid in the gall bladder, such as pregnancy can contribute towards gall bladder disease. There are examples of stasis causing hardening with other body fluids. For instance, bedrest can cause pooling of blood in the calf veins and arteries, which can cause blood clots. This hardening of the digestive juices does not manifest with symptoms while ON the low-fat regimens because there isn't a lot of digestive juice production or gall bladder contraction going on at the time. But, if a person then goes back to a diet higher in fat, the brain sends the signal for the gall bladder to contract...and the gall bladder tries to do this. Only problem is that the hardened juices (gall stones) are blocking the way for the newly-produced digestive juices to get to the common bile duct and out into the intestine.

Now you got pain!

For someone not aware of the physiology, it seems to be that the higher-fat diet has caused the problem, when the reality is that the lower-fat diet caused the problem. It's the higher-fat diet that allowed the problem to cause symptoms.

I hope that this explanation is clear enough for everyone to understand.
