does bmi correlate to how often u get sick
because it shows if you're underweight or overweight.
both sides can cause you to get sick more often
i wouldnt rely on BMI too much as it's not great as an individual-person scale metric
however yes it does. being very underweight or overweight will impair your immune system leading to you getting sick more. though it's also quite likely that people who are very under/overweight have bad eating habits and dont get good nutrition (vitamins, minerals, etc) which will also make the issue a lot worse and isnt accounted for by BMI directly
To add to this, obesity is associated with chronic inflammation which leads to impaired immune function
No but don’t let people tell you BMI is a bad statistic, it does well to evaluate the average person
