I'm 8 days post-op and always tired.... weak.

I'm not feeling like I'm going to pass out or anything but just depleted !

After doing small things I feel drained ! My surgeon said it's normal but I'm so ready to have all the energy I hear about

The three most important elements after RNY gastric bypass surgery are to meet your daily protein, fluid and vitamin requirements. Food is secondary because your body is converting your stored fat into the energy that drives your body. Thus you lose weight.

Weight loss is achieved after surgery through meal volume control. You begin at 2 ounces (1/4 cup) per meal and gradually over the next year and a half increase the volume to 1 cup per meal. With this minuscule amount of food, it is next to impossible to meet your protein daily requirements by food alone, so therefore you need to rely on supplements such as protein shakes.

So make sure you are following the program requirements. Part of what you are experiencing is recovery from the surgery, but if you fall short on any of these three requirements, this can lead to the condition you are experiencing.

It is so normal. I felt that way until about week three... I still have days though and I'm 6 weeks post op. Just make sure you get your protein in. I can tell a difference in how I feel when I don't. It's major surgery.. Normal to take a lot out of you. Hang in there.. [emoji846]

Totally normal, i didn't start feeling myself till about week 8 post op, any little thing I did took so much energy, hang in there it gets better, just try to meet your protein goals it really helps!

Very normal. I am 6 weeks post op and still get fatigued when I do a little more than normal. Even my walks are slower than pre surgery right now.

I figured getting 600-800 calories a day requires some adjustments by the body. Remember how many calories we ate pre op? There were plenty to burn:-)

Give yourself time. Energy will come. I also find that if I'm well hydrated my fatigue is way less.

Take care

Just rest as much as you can or feel you need to. I took off about 3 weeks from work but went in after a week. I didn't make it more than about 4 hours and had to go home from being so tired. After a few months my energy level was crazy. I wasn't able to sleep more than an hour or two a night. About a year out ur seemed to level out. Hang in there; you'll get through it.

It's totally normal especially if you're on liquids only post-op. Your body is still healing & we're not eating real food. I'm almost 6-weeks post off & still tired but not like when I was on liquids only. I think in time when our bodies fully heal & when we can eat more normally, our energy level should be back or even better than ever.

My profile picture is not me. It's my "FITspiration" body.

I felt the same way until day 15 or the third week. Once I introduced pureed foods I had a lot more energy! Hang in there!!
