gallbladder
If you've ever offensive specialists in the human body, I voted in the gall bladder. This small, pear-shaped organ, is generally satisfied with sitting still, save the digestive bile, accumulate in the rocks, so the peace, but once it gets upset, it can lead the world, painful seizures to the patient exhausted, and absenteeism.
Bile produced by the liver contains a lot of cholesterol and soluble fluids needed for digestion. Sometimes these small particles in solid liquid irritant. The gallbladder reacts like a clam, turning the solid gallstones, you can sit for years without any problems. But if you eat too much rich food, alcohol or too much indulgence, or just too many stones in the gallbladder and the rebels, severe abdominal pain, nausea, vomiting and other unpleasant symptoms. Medication can help, and use the side-effects.
