Epidemiology of Cholelithiasis

Epidemiology- the branch of medicine that deals with the incidence, distribution and possible control of diseases and other factors related to health.

According to the National Institutes of Health, as many as 20 million Americans have gallstones. One may hear the incidence of cholelithiasis in terms of the 3 F's: Female, Fat, and Forty. The reason for this alliteration can be linked to the various onset symptoms of gallstones. It should be noted, however, that while many americans have gallstones, a high percentage of them may not even be aware of them. These are called asymptomatic gallstones, and people can live their entire lives without them causing any problems.

Female:
       Obviously men can get gallstones as well, but studies have shown that women with high estrogen levels are at an increased risk for gallstones.

Fat:
      While this 'F' may not be the most politically correct, it is true that individuals who struggle with obesity is associated with an increased risk of gallstones.

Forty:
      Forty years of age tends to be the average time people who are at risk for gallstones develop them. However, according to Savitsky, a more accurate age range is between 20 and 60 years of age. Even this, however is a stretch. My surgeon discovered I had gallstones when I was 10 years old and I got my gallbladder removed when I was 14.

Other factors that are associated with an increased risk for gallbladder disease include:

  • People of Native American, Mexican American and Northern European descent. 
  • Inflammation of the organ
  • Rapid weight loss and fasting
  • High fat diets

Thankfully, treatment for cholelithiasis is relatively easy. The details of this will be elaborated on in a later blog post. Essentially, some symptoms can be controlled with diet. If the Gallbladder must come out, however, the procedure is very safe and very straight forward. The diagram below from the CDC represents this;
