What are Gallstones?
Gallstones (also known as cholelithiasis) are pebble-like substances that form in your gallbladder (the organ responsible for storing bile).
Bile is a fluid that helps your body digest fat. When bile contains too much cholesterol or other materials, it can harden into gallstones. These gallstones can then block the normal flow of bile from the gallbladder, which can lead to pain.
Symptoms of Gallstones
In many cases, gallstones produce no symptoms. However, symptoms can arise when gallstones block the bile ducts (tubes that transport bile from the gallbladder to the small intestine for use in digestion). These symptoms, collectively referred to as biliary colic or a "gallbladder attack," may develop suddenly. They may include:
Since blockage in bile ducts can be complicated by a serious infection or rupture in the gallbladder, you should contact your doctor if you think you've suffered a gallbladder attack. If your symptoms are accompanied by prolonged pain (lasting for hours), nausea, vomiting, fever, chills, yellowish coloring in the skin or whites of the eyes, and/or clay-colored stools, seek immediate medical attention.
What Increases Your Risk of Getting Gallstones?
The following conditions increase your risk of developing gallstones:
Treatment
Standard treatment may include medication to dissolve gallstones. If biliary colic or biliary infection recur frequently, surgery to remove your gallbladder may be performed.
If gallstones do not produce any symptoms, treatment is not required.
Natural Remedies for Gallstones
Although research on the use of alternative medicine in treating or preventing gallstones is limited, the following natural substances may help protect against gallstones:
1) Fiber
Research suggests that following a diet rich in fiber may help prevent gallstone formation. Fiber sources include whole grains, legumes, psyllium seeds, and flaxseeds.
2) Vitamin C
In a study of 13,130 adults published in 2000, researchers found that women with higher levels of vitamin C were less likely to develop gallstones. Vitamin C, which is essential for converting cholesterol to bile acids, is available in a number of fruits and vegetables (including citrus, berries, broccoli, and kale), as well as in supplement form.
3) Milk Thistle
Silibinin (a compound found in the herb milk thistle) has been found to reduce cholesterol levels in bile, which may in turn keep gallstones from forming. However, the data on this is very limited.
