I mean, really this is it. I'm fat, very fat in fact. Finding a doctor who isn't constantly trying to bully me into things I do not want (e.g., bariatric surgery) or lecturing about my weight when I go in to ask about a sinus infection like it has any relation at all is unbelievably frustrating. And it makes me not want to go to the doctor. I have several chronic illnesses; some are related to weight, others are not. And getting treated like a piece of shit every time I go see a doctor is awful.
I'm sorry that you ever felt that way leaving the house and you should definitely be able to use whatever the hell you want and makes you happy. We shouldn't focus so much about stuff other people do that doesn't have any impact whatsoever in our life.
Regarding that first paragraph and I don't mean to disrespect you, but as someone from the medical field I believe that every doctor that sees an obese person, no matter the problem, should indeed warn them of the risks of obesity and guide them towards weight lost and an healthier life-style. Now, it all comes down to how you approach the subject. If you feel "bullied", then they're doing it wrong and should be ashamed of themselves. No one should feel bullied or disrespected in an hospital setting.
You can be obese and have a normal blood pressure and all blood tests...
for now...(I'm assuming that you're a young adult), but it will indeed come back to do you harm in the future. Doctors are dealing with the results of the obesity pandemic, I doubt that they have any other interest in mind that isn't your health and your best interest (and theirs, because prevention is the best medicine, and they want to help you before both of you have to deal with the consequences). In limit situations bariatric surgery is indeed a way that works out great for a lot of people (others not so much, it comes down to many variables).
The good thing is that it is never too late to try to make a difference and every kg counts in decreasing those mid to late-life risks (I can only imagine that being from an obese family makes it much harder, because you have to go against your family's "culture" and lifestyle)
Recently a family member lost his dad to heart attack at the age of 50. His dad ate a lot and in a badly fashion and was clearly overweight. My family member was never obese, but he was chubby, and tried to lose wait for years with no success. After his father's dad he started running (training by himself and then social runs/marathons) and he's now in the best shape of his life and in much better shape than I am.
Again, this is maybe not the place and I don't want to seem like I am criticizing you. You should never feel the way you described it, specially at the doctor's office and I wish you the best of luck if you indeed try to lose weight ;)
