Grover Cleveland suffered from obesity and gout and was treated for cancer in his jaw while in office.

"President Cleveland was one of the most compelling stories of concealment in the high office," said Jerrold Post, professor emeritus of psychiatry, political psychology and international affairs at George Washington University. "He was brushing his teeth one day and found a lump on roof of the mouth. Instead of telling the public, he smuggled his dentist, head and neck surgeon and surgical team onto a pleasure yacht, where they removed the roof of his mouth to get rid of the carcinoma. He emerged a week later complaining of a toothache."

Theodore Roosevelt suffered from asthma and was blind in one eye as the result of a boxing injury in 1905. He was also deaf in one ear.

Woodrow Wilson had a debilitating stroke in 1919 that left him partially paralyzed while in office. According to Jerrold Post, Wilson had suffered several strokes while he served as president of Princeton but never revealed his medical history to voters.

While in office, "he suffered a massive stroke, but they concealed it and just said he was under the weather and no one was informed," Post said.

Franklin Delano Roosevelt was paralyzed in both legs, likely as a result of polio that struck when he was 39. But it was the cover-up of his advanced heart disease and elevated blood pressure when he ran for his fourth term that historians question. FDR died just a few months after that election.

George H. W. Bush was diagnosed with Grave's disease while in office. According to former White House physician Connie Mariano, "There was some question when he had hyperthyroidism, Grave's disease, around the time of the Gulf War. Did that make him more hyper and aggressive? Did it affect his memory, his ability to focus? It's hard to say." Luke Frazza/AFP/Getty Image
