I recently saw a neurosurgeon and was asked, "have you had any weight loss or weight gain that happened and you weren't aware of why?"
I replied that my weight fluctuates by 3 to 4 pounds but nothing more extreme. I am female, weighing normally around 122 but recently hit 127 and really didn't know why. I have lost it, but the odd thing is i also quit going to the gym where i mostly did cardio and started walking when i can. I know 5 pounds is probably not a major deal. I know how weight gain contributues to back issues, but why the concern with weight loss?
