A friend of mine had the bypass a few years ago. We don't see each other often so when we did it was a huge difference. She had chosen not tell anyone outside of family...and me when I asked. She's been my rock through this process. Any way what she tells people is that she and her doctor and dietician worked out a plan. She follows that plan. All totally true. Apparently it satisfies most people.
I haven't told any but a select few who I knew I'd need for emotional support. In the days following the surgery (which was last Wed 4/26) if I needed to explain my absence or fatigue I just said I had a procedure. Only one person asked what it was and I continued the conversation like I didn't hear him. From here on out...cuz I'm feeling pretty good...I'll stick with my doctor gave me a plan and I'm sticking to it.
