What is it?
Gallstones are hard lumps of crystals which develop within the gall bladder.
The gall bladder is a small sac underneath the liver.
When the gall bladder works normally it collects and stores bile from the liver.
Bile is a mixture of chemicals which help the digestion of food.
At meal times the gall bladder squeezes the bile out and into the intestines.
Stones develop from the chemicals in bile. They are usually made of cholesterol, but can also be from pigments produced by the liver and may contain calcium salts.
Many factors increase the risk of developing gallstones:
- Increasing gge
- Female sex
- High fat and low fibre diet
- Obesity
- Pregnancy
- High blood cholesterol
- Long term fasting
- Lack of gall bladder contraction
- Diabetes
- Cystic fibrosis
