Non-smoker Obama's fit to lead US says doctor

US President Barack Obama is in excellent health and tobacco free, his doctor said in the results of the president's second medical exam since taking office.

In the two-page report released by the White House, Dr Jeffrey C Kuhlman also said Mr Obama is physically active, eats a healthy diet, stays at a healthy weight, and on occasion drinks alcohol in moderation.

"The president is in excellent health and 'fit for duty'," Dr Kuhlman wrote. "All clinical data indicate he will remain so for the duration of his presidency."

Mr Obama, who turned 50 in August, seems to have improved his health on some fronts since his last physical, which Dr Kuhlman conducted in February 2010.

At that time, Dr Kuhlman said Mr Obama should stick with "smoking cessation efforts", and also said his cholesterol level had crept to borderline high and he should alter his diet accordingly.

Since then, Mr Obama, who chewed nicotine gun, appears to have quit smoking entirely -- an achievement his wife, Michelle Obama, announced earlier this year. And his cholesterol is now described as "ideal".

Mr Obama's total cholesterol level now stands at 193, compared with 209 in February 2010. His LDL, or bad cholesterol, is now 110, down from 138 last year.

Mr Obama works out and plays basketball and golfs.
