Comorbidity (say "koh-mor-BID-uh-tee") means that a person has two or more diseases at the same time. These are usually long-term (chronic) diseases that need treatment for a lifetime.
Comorbidities can change treatment options. One disease can make another disease worse, and the total effect of all the diseases may be more than each one on its own.
