Excess cholesterol in bile: Bile, a fluid produced by the liver to aid in digestion, contains cholesterol, bile salts, and bilirubin. When the bile contains too much cholesterol and not enough bile salts or lecithin (substances that help keep cholesterol dissolved), cholesterol can crystallize and form stones.
Bile composition: Changes in the composition of bile can lead to gallstone formation. For instance, if the bile contains too much bilirubin (a breakdown product of red blood cells), it can contribute to gallstone formation.
Poor gallbladder emptying: If the gallbladder doesn't empty completely or often enough, bile can become overly concentrated, leading to the formation of gallstones.
Obesity: Obesity is a significant risk factor for gallstones. It can increase the amount of cholesterol in bile and decrease gallbladder emptying.
Rapid weight loss: Losing weight too quickly can increase the risk of developing gallstones. When the body metabolizes fat during rapid weight loss, the liver releases extra cholesterol into the bile, which can lead to gallstone formation.
Age and gender: Gallstones are more common in women, especially those who are pregnant or taking hormone replacement therapy. They are also more common in people over the age of 40.
Cholesterol gallstones are the most prevalent type of gallstone, forming in about 80% of gallstone cases. These hardened deposits, typically yellow-green in color, develop in your gallbladder due to an imbalance in your bile composition. This imbalance can be caused by either too much cholesterol or a lack of bile salts, which are necessary to dissolve cholesterol.
Symptoms of cholesterol gallstones can include:
Diagnosing cholesterol gallstones typically involves imaging tests such as:
The most common treatment for cholesterol gallstones is cholecystectomy, a surgical procedure to remove the gallbladder. Medications to dissolve gallstones are usually not an effective treatment for cholesterol gallstones.
Pigment gallstones, unlike their more common cholesterol counterparts, are formed from bilirubin, a waste product created by your liver during red blood cell breakdown. These gallstones appear dark brown or black and account for roughly 15% of all gallstones. Their formation is triggered by an excess of bilirubin in your bile or issues with bile flow out of the gallbladder.
Similar to cholesterol gallstones, pigment gallstones can cause these symptoms:
Diagnosis of pigment gallstones often follows the same path as cholesterol gallstones, utilizing imaging tests like:
Treatment for pigment gallstones can differ slightly from cholesterol gallstones. While cholecystectomy (gallbladder removal) is still an option, it's sometimes not necessary. If your pigment gallstones are causing minimal problems and the underlying cause of excess bilirubin can be addressed, your doctor might recommend monitoring the situation. In some cases, medications like ursodeoxycholic acid may be prescribed to help dissolve pigment gallstones. However, this approach is not always successful. If your pigment gallstones are causing significant discomfort or complications, then gallbladder removal surgery might be the best course of action.
Laparoscopic cholecystectomy is the most common type of surgery for gallstones. It is a minimally invasive procedure that uses small incisions in the abdomen. The surgeon inserts a laparoscope, a thin tube with a light and camera on the end, into one of the incisions. The surgeon then uses other instruments inserted through the other incisions to remove the gallbladder. Laparoscopic cholecystectomy is associated with less pain, shorter hospital stays, and a faster recovery time than open cholecystectomy.
Open cholecystectomy is a traditional surgery that uses a larger incision in the upper right abdomen to remove the gallbladder. Open cholecystectomy may be necessary if the laparoscopic procedure is not possible due to scar tissue from previous abdominal surgery, inflammation, or other factors.
Both laparoscopic cholecystectomy and open cholecystectomy are safe and effective procedures. The best type of surgery for you will depend on your individual medical condition.
Not everyone with gallstones will need treatment. If you don't have any symptoms, you may not need to do anything. However, if you experience pain, nausea, vomiting, or other symptoms of gallstones, treatment is recommended to prevent complications.
The most common treatment for gallstones is surgery to remove the gallbladder (cholecystectomy). This is a minimally invasive procedure that can be done laparoscopically. In some cases, medications or other procedures may be used to dissolve or break up gallstones.
A cholecystectomy is a surgical procedure to remove the gallbladder. It is typically performed laparoscopically, which means that several small incisions are made in the abdomen and a tiny camera is inserted to view the gallbladder. The surgeon then uses long, thin instruments to remove the gallbladder.
Cholecystectomy is a safe and common procedure. However, as with any surgery, there are some risks involved, such as infection, bleeding, and damage to nearby organs.
Most people recover from cholecystectomy quickly and can go home the same day or the next day. You will likely have some pain and discomfort at the incision sites, but this can be managed with medication. You will also need to follow a special diet for a short time after surgery.
If gallstones are left untreated, they can cause complications such as cholecystitis (inflammation of the gallbladder), cholangitis (infection of the bile ducts), and pancreatitis (inflammation of the pancreas).
There is no guaranteed way to prevent gallstones, but there are some things you can do to reduce your risk, such as maintaining a healthy weight, eating a healthy diet, and exercising regularly.
