Gall stones are not exactly stones. They're pieces of solid material that form in the gallbladder, which is a small organ located under the liver.
You might not even know , you have them until they block a bile duct, causing pain .
The pain felt on right upper abdomen should be ruled out and treated as soon , so that it might not grow big and cause severe pain to go for a surgery to remove the gall bladder itself ( cholecystectomy)
Gall bladder polyp
Gall bladder polyps are a growth or lesion projecting from the gall bladder
Types of gall stones :
The two main kinds are:
Cholesterol stones
These are usually yellow-green in colour. They're the most common kind, accounting for 80% of gallstones.
Pigment stones
These stones are smaller and darker, formed from excess bilirubin in the bile. It is a substance produced when the body breaks down red blood cells.

Symptoms
Note :
Increase in body heat ( due to spicy foods , insomnia , increased sexual activities ,travel etc ) would cause rapid destruction of RBC’s ( Red Blood cells ) which in turn increase the bilirubin to form gall stones .
Treatment :
There are always natural herbs, to cleanse out the gall stones , which can help you save your gall bladder without it being removed . The ancient herbal formulations derived from the Tamil manuscripts have seen to dissolve the stones naturally via faeces. ( In case of cholecystectomy, the metabolism becomes very low leading to indigestion, (especially fat metabolism) hyper cholesterol, GERD ( acid reflux ) etc which may also cause Heart blocks .
