Blind Spots: When Medicine Gets It Wrong, and What It Means for Our Health
Johns Hopkins UniversityTue Sep 17 2024
In the medical world, there are instances where doctors and medical professionals have gotten it wrong, leading to unintended and often devastating consequences. These blind spots are often rooted in dogmatic thinking, groupthink, and a lack of critical evaluation of the evidence. In his book "Blind Spots: When Medicine Gets It Wrong, and What It Means for Our Health," Dr. Marty Makary, a surgeon and professor, examines four instances where medical professionals got it wrong.
One such instance is the recommendation to avoid peanuts for young children to prevent allergies. In 2000, the American Academy of Pediatrics (AAP) issued a guideline advising children under the age of 4 and pregnant and lactating women to avoid peanuts due to a perceived risk of allergy. However, this recommendation was based on a flawed study, and the lead author of the study, Jonathan Hourihane, later said that he opposed the guidance. The recommendation led to a surge in peanut allergies, which became increasingly deadly.
Another example is the promotion of hormone replacement therapy (HRT) as a safe and effective treatment for menopausal symptoms. However, in 2002, the National Institutes of Health (NIH) declared that HRT increased the risk of breast cancer. Although the data did not support this conclusion, the recommendation led to a sharp decline in the use of HRT, denying millions of women a life-changing treatment.
The overprescription of antibiotics is another instance where medicine got it wrong. Antibiotics are lifesaving, but they are often overprescribed, leading to harmful effects on gut health. A study published in 2021 found that children who received antibiotics in their first two years of life had higher rates of obesity, asthma, learning disability, ADHD, and celiac disease.
Lastly, the practice of adding fluoride to drinking water is also being questioned. While fluoride was initially added to prevent tooth decay, recent research suggests that it may not be as effective as once thought. Additionally, some studies have raised concerns about the potential negative effects of fluoride on gut health and IQ in babies.
