Republican vice presidential candidate Sarah Palin is in excellent health with no known health issues that would interfere with her ability to perform her duties if she and John McCain are elected , her family doctor says.
McCain's campaign released a summary of Palin's medical history yesterday night.
Palin had promised several weeks ago to release the information, following similar releases by McCain, and Democrats Barack Obama and Joe Biden.
In a two-page letter, Dr Cathy Baldwin-Johnson, Palin's personal family physician in Alaska since 1997, said Palin has only been hospitalised for childbirth.
The Alaska governor is a 44-year-old mother of five. Son Trig, born earlier this year, has Down syndrome.
Palin had a breast biopsy in 1992 for what turned out to be a benign lesion. Her vital signs, including blood pressure and pulse, have been normal, the summary said.
Baldwin-Johnson said Palin has no close relatives with major health problems.
Palin also takes no routine prescription medications and exercises regularly.
The campaign's decision to release a brief summary letter is consistent with what Obama did earlier this year.
Obama did not release records, but rather a letter from his personal physician attesting to the 47-year-old's good health. Obama has very good cholesterol levels, outstanding blood pressure and no sign of heart disease. He is a smoker who has quit but relapsed several times. He announced in February that he was quitting again with the aid of Nicorette gum.
