The Claim

Atorvastatin therapy in humans is associated with a decreased abundance of the genus Clostridium in feces and altered serum and fecal bile acid profiles, which correspond with the development of glucose intolerance over a 16-week period in a cohort of 30 patients.

Source: Statins aggravate insulin resistance through reduced blood glucagon-like peptide-1 levels in a microbiota-dependent manner.

Support is ahead, but a single strong opposing study can change this.

In plain English

In humans taking atorvastatin, the abundance of Clostridium bacteria in feces decreases, bile acid levels in serum and feces change, and glucose intolerance develops over 16 weeks.

Atorvastatin therapy in humans is associated with a decreased abundance of the genus Clostridium in feces and altered serum and fecal bile acid profiles, which correspond with the development of glucose intolerance over a 16-week period in a cohort of 30 patients.

Why this might work

Atorvastatin lowers levels of certain gut bacteria called Clostridium, which changes the types of bile acids in the body. These changed bile acids reduce the production of a hormone called GLP-1, which normally tells the pancreas to release insulin after eating. With less GLP-1, the pancreas releases less insulin, causing blood sugar to rise over time.

  1. Study: Statins aggravate insulin resistance through reduced blood glucagon-like peptide-1 levels in a microbiota-dependent manner.

    Taking atorvastatin for 16 weeks lowered certain gut bacteria and changed bile acids, which made blood sugar harder to control — and giving a specific bile acid (UDCA) fixed the blood sugar problem without affecting cholesterol benefits.
