GALL BLADDER

What is the Gallbladder?

The gallbladder is a pear-shaped organ that can accomodate upto 60 ml of bile (or "gall") until the body needs it for digestion.
The gallbladder is about four inches long and is attached to the liver by tiny bile ducts. .

The gallbladder stores about 50 ml of bile, which is made by the liver,which is released when food containing fat enters the digestive tract, stimulating the secretion of cholecystokinin (CCK). The bile, produced in the liver, emulsifies fats and neutralizes acids in partly digested food.
After being stored in the gallbladder the bile becomes more concentrated than when it left the liver, increasing its potency and intensifying its effect on fats. Most digestion occurs in the duodenum.

What are Gallstones?
Gallstones, which are calcified chunks of cholesterol and bilirubin, are formed when the gallbladder doesn’t empty properly, creating a stagnant environment. They can be painful, especially if they pass out through or get stuck in the bile ducts. However, a person could have gallbladder problems even before stones form.
Stones, especially the larger ones, can irritate the lining of the gallbladder and cause acute infection. In this case, urgent medical care is needed, including antibiotics. Gallstones can be easily seen with an ultrasound

Removal of the Gallbladder?
In some cases, the gallbladder must be removed. The surgery to remove the gallbladder is called a cholecystectomy. In a cholecystectomy, the gallbladder is removed through a 5- to 8-inch long cut in your abdomen.
Once the gallbladder is removed, bile is delivered directly from the liver ducts to the upper part of the intestine.

Complications from Gallbladder removal?
Complications are rare. When complications occur, they may be in the form of: bleeding, infection and injury to the duct (tube) that carries bile from your gallbladder to your stomach.
Some patients also experience diarrhea. The cause of diarrhea after gallbladder removal isn't clear

Gall Bladder treatment using BeetFresh juice of beets, and the juices of carrot and cucumber in quantities of 100 ml each, are one of the finest cleansers of the gall-bladder. This combined juice has proved beneficial in the treatment of all disorders related to this organ, and should be taken twice daily. Gall Bladder Disorder treatment using PearThe pear is another excellent remedy for gall-bladder disorders. The fruit or its juice should he taken liberally by the patient with beneficial results. It exercises a special healing effect on all gall-bladder disorders, including gallstones. Gall Bladder treatment using ChicoryThe flowers, seeds, and roots of chicory or the endive plant are considered valuable in gall-bladder disorders. A decoction of about 30-60 ml of the flowers, seeds, or roots can be used three times daily with beneficial results in the treatment of these disorders. Endive or chicory juice in almost any combination promotes the secretion of bile and is, therefore, very good for both liver and gall-bladder dysfunctions. Gall Bladder treatment using DandelionDandelion has a beneficial effect on the gall bladder. About 125 ml each of the juices of dandelion and watercress should be taken twice daily. Combined with a vegetarian diet, without much sugar and starch, these juices help to make the gall¬bladder normal. Gall Bladder treatment using Olive and Sunflower OilAn oil cure has been advocated by some nature cure practitioners for the removal of gallstones. Raw, natural, unrefined vegetable oils of olive or sunflower are used. The procedure is to take 30 ml of vegetable oil, preferably olive oil, first thing in the morning and follow it immediately with 120 ml of grapefruit juice or lemon juice. This treatment should be taken every morning for several days, even weeks, if necessary.
