Gallbladder is a small organ present in the liver that stores the bile juice secreted by the liver. Gallstones are not the real stones but small chunks of solid material that form in the gallbladder. You may not be aware of their presence in your body until these gallstones block a bile duct resulting in severe pain.
Mainly there are two kinds:
- Cholesterol Stones – 80% of the gallbladder stones are of this type and are usually yellow-green in color.
- Pigment Stones – These stones are formed by bilirubin and are small & dark. Bilirubin is a pigment present in bile juice.
Diet, your weight & genes and problems with gallbladder are some of the several gallstones causes. This problem might even arise due to bile juice. Bile aids in the digestion process and hence the body requires it. But if it contains cholesterol, the chances of getting gallbladder stones are more likely.
If your gallbladder doesn’t empty properly then it may also lead to these stones. People with certain health conditions such as cirrhosis of the liver or sickle cell anemia are more likely to get pigment stones.
Following are the risk factors:
- Estrogen – High estrogen levels increases cholesterol formation thus making it difficult for gallbladder to empty its contents. Increased estrogen levels may be due to birth control pills, pregnancy or the hormone replacement therapy taken for menopause.
- Obesity – It also increases the cholesterol in the body there by harder for the gallbladder to empty completely. It is one of the biggest risks.
- Weight – Losing weight too quickly makes the liver to produce extra cholesterol thus leading to gallbladder stones.
- Fasting – During fasting, your gallbladder will have problems emptying.
- Medicines – Some of the medicines you may take to lower your cholesterol may actually increase its levels in the bile. This is more likely to lead to cholesterol stones.
- Diabetes – Triglycerides, a type of blood fat is present in high levels in people with diabetes. It is a risk factor for gallbladder stones.

This dye colors the bile duct and makes it visible. With this he can also remove the gallbladder stones that have blocked the bile duct.
Treatment for Gallstones
Treatment for gallstones includes surgery for the removal of the stones. Two kinds of surgeries are usually done.
It is the most common procedure for gallstones removal. Several small cuts are made in the belly. Through these small cuts, the surgeon passes a light, camera and instruments. A video monitor displays the views of inside of the body. After the surgery, you spend a night in the hospital.
Bigger cuts are made in the belly and the gallbladder is removed. After the operation, you have to stay for a few days in hospital.
If the gallbladder stones are blocking the bile ducts, the doctor uses the ERCP method to remove the gallstones either before or during the surgery.
Gallstones Treatment Without Surgery
Your doctor may recommend medications if you have a medical condition for which doing an operation would be risky. Doctor will prescribe medications like chenodiol (Chenix), ursodiol (Actigall), or both. These medications help to dissolve the cholesterol stones. The side effect may include mild diarrhea.
The problem with using medications is that to completely dissolve the stones, you have to take the medications for years. Sometimes, it may come back after discontinuing of the drug.
