Why would a person self esteem affect his or her health

When someone has low self-esteem they may have problems with relationships, Health, and commonly negative feelings. Which all affect someone's mental and physical state.  High self esteems are normally more proactive and positive. They are keeping themselves healthier and caring about themselves. (not all but it is common).

Hope this helped!
