Is the word 'obese' a slur?

I'm not trolling. I saw this very topic brought up on social media with someone describing the term obese as a slur even if it is a medical term. I'm looking for input perhaps from some docs who have had to have difficult discussions with patients about weight. Did you use the term obese? Is there any other way to address someone that is considerably large in size?
