7.Ronald Reagan
No. 40 (1981-1989) During his second term, Reagan was successfully treated for colon cancer (1985) and skin cancer (1985 and 1987). Following his presidency — after he’d been out of office about 5 years — he was diagnosed with Alzheimer’s disease (1994). He died in 2004 with the official causes listed as Alzheimer’s and pneumonia, a common health problem for people with that form of dementia.
8.William Taft
No. 27 (1909-1913) This president struggled with his weight throughout his life. He had a huge appetite and was clinically obese. At just under 6 feet tall, Taft weighed about 340 pounds when he left office. He had sleep apnea, among other conditions that may have been caused or made worse by his weight. He died of complications related to heart disease, high blood pressure, and bladder inflammation in 1930.
