What is up with me? I am tired so quickly anymore. Tried doing a work out today that I did 40 lbs ago, and could not finish. I just don't get it....

And my hair is breaking and thinning taking all of my Vitamins so what am I missing?

How far out are you? I know my first month out I was exhausted all the time. I think it's mostly to do with lower calorie intake. Your body will adjust. As for the hair... It's something we have to look forward to. If you search the site, there are lots of threads on this and all have some great ideas. Just hang in there. Keep your eye on the prize :-)

When was your surgery? How many calories per day are you eating and in what quantities?

Even though I was walking every day, it took weeks for me to work up a decent amount of stamina and endurance. I'm better than 3 months post op and am just really able to get into my old exercise routines.

I dare say, most people experience hair weakness and loss. The general consensus is (and my NUT agrees) that you'll thin out for 3-5 months between 3 and 5 months post surgery. Getting your Protein in, and supplementing with Biotin and Zinc are doctor's order for me.

For better or worse, sounds like you are right on track! :-D

I was sleeved April 30th. I consume 600 to 800 calories daily, typically in 200 calorie increments.

Pre-surgery I was on a hair supplement, but I can no longer get it down.

My fatigue has been increasing. If it is just a phase than that is comforting to know. My surgeon wants me to work out even more, but frankly I have never been so in tuned with my body as I am now (one of many awesome blessings) and my body wants rest. I have enough steam for small bursts of physical activity and then I have an overwhelming need to rest.

Biotin for the hair loss is good

How many calories did your nut recommend ? Mine told me I needed to build up to 1200 with time and healing. Personally you need more calories. We all have different needs based on our weight to just maintain normal functions. Sounds to low to me . Talk to your nut
