comorbidity
nounkoh-MOR-bih-dih-tee
meaning in plain English
Having more than one health problem at the same time, where one is the main issue and the others are extra.
for example
When someone has diabetes and also high blood pressure at the same time, doctors call that comorbidity.
Comorbidity means your body is dealing with more than one sickness at once. Imagine if you sprained your ankle and then caught a bad cold right after—now you’re managing two problems together, which is what comorbidity looks like in real life.
