President Bush suffers from several physical ailments but has no history of heart problems.

He has had serious allergic reactions twice, the most recent at an Auburn University football game in 1978, when he was stung by a bee. The reaction was stopped by a doctor before it developed into classic anaphylactic shock, an allergic condition that can cause death.Bush has since taken immunotherapy injections to stave off such reactions.

In World War II, when he was in the Navy, Bush passed out when he had shots or had to have a blood sample taken. He does not give blood because he suffered hepatitis as a teenager, making him ineligible.

The president takes non-sedating antihistamine pills to control hay fever in the spring. He also has mild arthritis of the hips and knees that led him to cut back on his jogging.
