(CNN) Elizabeth Warren's presidential campaign on Friday released the results of the senator's most recent annual physical exam, as well as a letter from her doctor that said Warren is a "very healthy 70 year old woman" with no medical conditions that would prevent her from serving as president.

Warren's latest physical was conducted on January 14, according to her long-time physician, Dr. Beverly Woo of Brigham and Women's Hospital in Boston. Woo said that the exam showed Warren's blood pressure, heart rate and blood tests were all normal, her cholesterol was "excellent," and that Warren also had a mammogram to screen for breast cancer. Warren is 5 feet 8 inches tall and weighs 129 pounds, and received a flu shot in October, Woo wrote in the letter.

Woo said that Warren's one medical condition is hypothyroidism, and that she takes levothyroxine every day to restore her thyroid hormones to normal levels. Hypothyroidism is a condition where the thyroid doesn't produce enough of certain hormones. It most often affects women who are middle-age and older, according to Mayo Clinic

"Senator Warren has never smoked, used drugs or had any problem with alcohol use. She exercises regularly and follows a healthy diet despite her very busy schedule," Woo wrote in the letter. "In summary, Senator Elizabeth Warren is a very healthy 70 year old woman. There are no medical conditions or health problems that would keep her from fulfilling the duties of the President of the United States."

Warren's communications director Kristen Orthman told CNN that Warren will get her yearly exam again in 2020 and that the campaign will release those records again when she does.
