Correct me if I'm wrong but you're probably only taking in 500-600 cals a day at this point. That's not enough fuel to sustain a walk of a few miles even if you took it easy. Especially not even 2 weeks post-op. You have been calorie restricted with the pre-op diet and severely restricted week one I imagine. There is no reserve to draw on at this point, so when you over exert it's a quick cascade to feeling miserable.

As for the headaches.. did you give up cafeine? I did and i had a couple of of monster headaches the first week or two. I know headaches can be a symptom of dehydration, but you said your intake is good so I'm stumped. If these symptoms persist you should give your surgeon a call.

I don't know what your Drs. recommend, and not knowing what kind of shape you are in, my first thought was that you should give your body and chance to heal. I know I way underestimated the time it would take to heal and get my energy back. I was definitely not walking "a few miles" 2 weeks post op - I tried, but felt awful. Try not to over do it, and listen to what your body is telling you. At three months out, I feel amazing, full energy, walking etc. You'll do great!! You'll see!!

Any tips on getting through the next few weeks? I am a week post-op and feel like death. Nothing tastes good. Everything makes my stomach hurt. I get full REALLY fast. Most days I am getting my protein in, but I am having a hard time getting all the required fluids in. Premier protein shakes have saved my life. The only shake I can tolerate. I just never feel hungry or thirsty anymore. Please tell me this goes away over time.

You could ask the nutritionist for a diet.

I personally did a low carb diet. It is very difficult for the first week or two, but after that it was much easier. It was also very close to how we eat post-op for the most part.

I browsed through two sections of yogurts in Meijer's tonight. There is NO yogurt of any kind that is low carbs. Most I looked at had around 12 g of sugars per serving. Granted, our serving size isn't as large as theirs but I thought the whole idea was to limit carb intake and get protein instead. Some yogurts have only 2-3 g of protein! In my mind, hardly worth eating.
