After a whiplash-inducing morning of mixed messages, Donald J. Trump on Wednesday opened a small window into some of the results from his most recent physical examination, revealing that he is overweight and takes a statin, a type of drug that lowers cholesterol.

Mr. Trump gave the quick synopsis on Dr. Mehmet Oz’s television show after the Republican presidential nominee’s aides had said that he would, then that he would not, broach the topic with the doctor on the show.

A news release from the “Dr. Oz Show” said that Dr. Oz, “as all physicians do when seeing a patient for the first time,” took the candidate “through a full review of systems including the following: nervous system; head and neck; hormone levels; cardiovascular health and related medications; respiratory health; gastrointestinal health; bladder or prostate health; dermatological health; history of cancer.”

The release also said they reviewed “family medical history — occurrence of Alzheimer’s or dementia, heart disease, cancer in relatives.”
