JFK disingenuously withheld important personal health information from the press and public before and during his presidency. While projecting a false image of youth and vigor, he was actually a very sick man, secretly taking numerous drugs and seeing multiple doctors. Had his true state of health been understood by the public, he likely would not have been elected president in 1960.
Kennedy suffered from colitis, prostatitis, and a disorder called Addison's disease, which affects the body's ability to regulate blood sugar and sodium. He also had osteoporosis of the lower back, causing pain so severe that he was unable to perform many simple everyday tasks. To fight the pain, Kennedy took as many as twelve medications at a time, taking more during times of stress. Medical records reveal that JFK variously took codeine, Demerol and methadone for pain; Ritalin, meprobamate and Librium for anxiety; barbiturates for sleep; thyroid hormone; and injections of a blood derivative, gamma globulin, a medicine that combats infection.
During the Bay of Pigs fiasco in 1961, and the Cuban Missile Crisis in October 1962, Kennedy was taking steroids for his Addison's disease, painkillers for his back, anti-spasmodics for his colitis, antibiotics for urinary tract infection, antihistamines for his allergies, and on at least one occasion, an antipsycotic drug to treat a severe mood change.
The secret details of Kennedy's medical history were buried in old boxes of records the JFK Presidential Library had held for forty years. Past requests for access to these materials had always been refused by a committee of loyalists including one of Kennedy's closest advisors, Ted Sorensen (see "Irish Mafia" above). Only with the eventual deaths of these gatekeepers have the records come to light in 2002.
While JFK lied by omission to the American people, he flat out denied his Addison's to running mate Lyndon Johnson, fearing that the truth would get out and harm his chances against Nixon in the 1960 Presidential campaign.
