Gallbladder removal and vitamin D deficiency

It appears that

  • Gallbladder surgery is very common: 500,000 - 750,000 in US each year
  • Low vitamin D may cause gallbladder stones to form
  • Gallbladder removal may reduce vitamin D and Magnesium levels
  • Bile from the gallbladder aids the processing of vitamin D in the gut: see PDF at bottom of this page

A 2010 bulletin published by the Ontario Provincial Programs Branch explains that individuals who have had gallbladder removal may also experience a vitamin D deficiency due to absorption problems. Additionally, if you have gallbladder disease or gallstones, you may also be at risk for a deficiency of this vitamin.

Demographics: Overweight, middle-aged females

Gallstones are approximately two times more common in females than in males. Overweight women in their middle years constitute the vast majority of patients with gallstones in every racial or ethnic group. An estimated 10% of the general population... has gallstones. The prevalence for women between ages 20 and 55 varies from 5–20%, and is higher after age 50 (25–30%). The prevalence for males is approximately half that for women in a given age group. Certain people, in particular the Pima tribe of Native Americans in Arizona, have a genetic predisposition to forming gallstones. Scandinavians also have a higher than average incidence of this disease.

Strong genetic correlation

There seems to be a strong genetic correlation with gallstone disease, since stones are more than four times as likely to occur among first-degree relatives. Since gallstones rarely dissolve spontaneously, the prevalence increases with age. Obesity is a well-known risk factor since overweight causes chemical abnormalities that lead to increased levels of cholesterol. Gallstones are also associated with rapid weight loss secondary to dieting. Pregnancy is a risk factor since increased estrogen levels result in an increased cholesterol secretion and abnormal changes in bile. However, while an increase in dietary cholesterol is not a risk factor, an increase in triglycerides is positively associated with a higher incidence of gallstones. Diabetes mellitus is also believed to be a risk factor for gallstone development.
(Note: weight, pregnancy, diabetes, high blood pressure are associated with gallstones and are associated with low levels of vitamin D)

Gallstones affect approximately one in ten Americans, and are associated with approximately 3,000 deaths annually.
More than 800,000 hospitalizations each year are caused by gallstones that are large enough to cause significant pain.
Over 500,000 people undergo surgery for gallstones annually.
Obesity is one of the strongest risk factors for gallstones.
Rapid weight loss diets significantly increase the risk for gallstones.

Gallbladder concentrates the bile from the Live so that it can be used to digest fats in the colon. Gall stones are made of cholesterol.

Diarrhea (and poor digestion of Vitamin D, Magnesium, etc) after gallbladder removal varies from 1 in 3 to 1 in 100

Mayo http://www.mayoclinic.com/health/gallbladder-removal/AN00067
Studies have found as few as 1 in 100 people undergoing gallbladder surgery or as many as 1 in 3 develops diarrhea.
In most cases, the diarrhea resolves soon after the surgery. Rarely, it may last for years.

Note to those with poorly functioning guts:

There is a form of vitamin D for those with poor gut functions
There is a form of vitamin D for adsorption under the tongue - never getting to the gut
There is a form of Magnesium topically as well: both Magnesium Chloride liquid and Epsons salts
All items in category Gut and Vitamin D 62 items

There is a free and instant test for vitamin D deficiency

If you are thus confirmed to be very deficient of vitamin D

Overview Deficiency of vitamin D has a chart - the following is a portion of that chart - showing vicious cycles


Seem strange that I have never noticed Vitamin D studies asking if participants still had gallbladders.
Gallbladder removal reduces vitamin D levels and will probably result in poor bio-availability of most (fat soluble) vitamin D supplements
