DES MOINES, Iowa (AP) — Democratic presidential candidate Bernie Sanders is releasing information about his medical history. His doctor says in a 1-page letter that Sanders is in "overall very good health."
The letter released by the campaign says the 74-year-old Vermont senator has been treated in the past for ailments like gout, high cholesterol and laryngitis. He underwent hernia surgery earlier this year.
Sanders' doctor Brian Monahan says the senator is in "overall very good health and active in (his) professional work, and recreational lifestyle without limitation."
If elected, Sanders would be the oldest president to assume office, surpassing Ronald Reagan who was 69 when he entered the White House.
