Our new case study highlights why it's important for physicians to better understand the body's response to #exercise #training. 🧵1/5

🔓journals.lww.com/jfmpc/Fulltext… #medicine #liver #physiology @theliverdr
In Oct 2021, I had a routine blood test that revealed elevated liver enzymes. A later blood test with a different doctor showed the liver panel was "elevated and worsening", more than double the normal range for some variables. 2/5
A series of additional tests, including abdominal ultrasound, were negative. Physician referred me to a gastroenterologist who suggested (an invasive) liver biopsy. However, before the next blood test, I stopped exercising for 7 days. 3/5
Values basically normalized, suggesting the elevated "liver panel" was the result of exercise-induced muscle damage and/or increased hepatocyte membrane permeability. Remember, ALT and AST have an important role in Krebs, not just in "liver function" 4/5
Importantly, none of the doctors assessed muscle function (e.g., CK) or enquired about my exercise training habits. "Such omissions in the diagnostic pathway can result in the misdiagnosis of liver problems and unnecessary follow‑up tests and referrals." 5/5

END.

"The originally-published data are inaccurate and a complete set of corrected data is not available."

Here's a thread to outline the worrying data irregularities that led to this retraction.

I was asked recently to provide some examples of health and fitness marketing that makes false claims and/or exploits human biases. I came up with a billion examples. Here are just 6:

#science #skepticism #criticalthinking #exercise #health
1/6. All-natural #wheyprotein. It exploits the irrational cognitive bias towards natural products.
2/6. L-carnitine sold for decades as a ‘fat burner’ despite research which failed to show consistent and reliable outcomes.

The official #Olympics website endorsing #cryotherapy as an effective form of post-exercise recovery. Despite the fact the literature is very unimpressive, littered with low-quality studies, and tiny effects. #IOC

Even the FDA are ahead of the game on this one, which is rare: fda.gov/consumers/cons… Image
