Is it OK to give a gift to my doctor? Or is that putting him into an awkward (or even unethical) situation?

I'm 56. I've been obese for over 25 years. Nothing worked to get it off. A few years ago I went to a cardiovascular specialist to get a VNUS (vein) procedure done. He took an interest in my weight and last year around this time prescribed me a newish weight-loss drug named Contrave. He's been following up with me regularly and I don't know what it is about him, but he just has a right method of encouragement that is helping me to make this happen.

So I'm not sure if that drug really works or it was his encouragement or I was just fed up with being fat, but so far I've lost 70 pounds and I've got about 20 to go.

It's made a HUGE difference in my life. Last year I was having trouble walking. Now I'm riding a bicycle, jogging a few times a week, and doing 10 mile hikes in the mountains near where I live. I used to suffer from depression but not now. I used to have high BP but now now.

I realize doctors save lives all the time, and my case isn't all that miraculous, but to me it has turned my life around. I would just like to offer a token of my gratitude like a thank you card and a gift card to a nice restaurant.

Is that an appropriate thing for a patient to do? I certainly don't want to put him into an uncomfortable situation after all he's done for me.

Thanks. My next appointment with him is this Monday.
