My mom says she has a gallstone! Is it really a stone? And what does your gall bladder do, anyway?

Dear Rocky



Don't worry. Gallstones are just called gall "stones." Your mother doesn't have a small rock inside of her. But what she does have is a hard lump of a chemical called cholesterol in her gallbladder or a tube leading from her gallbladder.

First things first. Your gallbladder is a small pear-shaped sac behind and to the left of your stomach. Its purpose? To store excess bile -- that greenish mix of chemicals that helps digest fat.

Where's the bile come from you say? It's made by your liver. When your stomach is full, you need bile to help digest the fat you've eaten. Bile drips directly from your liver into your stomach. But, when your stomach is empty, the valve to your stomach slaps shut. Instead of the bile dripping from your liver into your stomach, it drips into your gallbladder which holds it until you eat again.

Sometimes the recipe for the bile the gallbladder is storing is a little off. That's when "stones" form. Such "stones" can irritate your gallbladder, cause an obstruction or become a home for bacteria. In all these cases, a doctor is needed. Often, surgery is required to remove them -- but you come out just as good as new. And, by the way, don't worry. More females than males seem to be troubled by gallstones -- but they tend not to occur until you're forty or fifty years old! I assume you've got many decades before you're that age, right?

Wendell
