Found just under the liver, sits the gallbladder. This pouch is a storage unit for the liver’s bile, as well as fat, cholesterol and various fluids. This pear-sized balloon is inflated before meals when it is filled with bile. After eating, the balloon then looks flat and deflated. This bile is used to help digests fats. When food is detected, the gallbladder releases bile into the small intestine. But wait, don’t some people have their gallbladders removed? Yes, because even though the gallbladder plays a role in digestion, it is not an essential organ. Once the gallbladder is removed, the body compensates and still performs its tasks. There are a number of reasons why someone might have their gallbladder removed.
Certain health conditions and risks can complicate the gallbladder’s existence, a few of them are...
When a person feels pain near their low back or has trouble keeping food down, it is important to find out the cause of their suffering, as it could relate to the gallbladder. There are a few different tests a doctor can perform to diagnose gallbladder conditions. The most noninvasive and primary approach is to do an abdominal ultrasound or an x-ray. The ultrasound will check for gallstones. An MRI can take high resolution images for the doctor to review and an endoscopic retrograde cholangiopancreatography (ERCP) can be used, which requires a tube being inserted into the mouth down to the small intestine. The doctor can see through this flexible tube and inject dye into the bile. An HIDA scan can be used which is when a doctor injects the dye intravenously.
For an organ that doesn’t literally "HAVE" to be there, it sure can cause pain and there are a few methods to treat a dysfunctional gallbladder. Antibiotics can be used to attempt to reduce an infection and prevent spreading. Gallbladder surgery, which is called cholecystectomy, can be done to remove the organ. If cancer to the area has occurred, chemotherapy can be used. There is an oral medication called ursodeoxycholic acid, which can help dissolve gallstones; this can also be done by injection of a solvent solution. Gallstones can be broken up using shock wave therapy, which is called lithotripsy. Whichever method is used, any time the body communicates pain, there is a reason. When eating becomes difficult and digestion is accompanied by pain, the gallbladder just might be the culprit behind the discomfort and suffering.
