I started my pre-op diet 9 days ago and since then I have developed a rash that started on my upper thighs and arms. I first thought it was a heat rash but it is spreading. It is now on the tops of my feet. They ONLY thing I've changed in this time frame is that I am on the whey protein meal replacement shakes for 2 weeks prior to my surgery. Upon googling this problem with the whey I did find that sometimes you can develope an allergy to it. Has anyone else had this problem and if I can't use this whey protein what can I use as my meal replacement? Of course it is the weekend and I can't go to my drs office until Monday.

There are other protein drinks. Google non whey protein drinks. Or ask your nutritionist for some help.

Thanks, I will see what I can find but the nutritionist told us to be sure and use the whey protein. I didn't know if it would mess up my diet if I changed or not.

Bariatric doctors definitely like whey. I'm not exactly sure why, because there are other very good sources out there.

Here are a couple of links to some other good products. Egg white protein in VERY good, and many people do much better with it. Also - pea protein. I used to use the pea protein, prior to WLS. Now I use whey, but I will probably switch to egg white.

FYI - you can buy these in local vitamin/health food stores. Just call around your area:

Before I left the hospital they gave me Carnation Instant Breakfast high protein drink. There are 2 kinds, just make sure you get the higher protein one. Good luck but calling the dietitian is the smartest since every doctor has their own 'rules'.

I haven't had a reaction like that hit I'm doing the whey too and it upsets my stomach a lot. Some of the whey has lactose, so if you're lactose intolerant that would be causing a reaction. If you use the whey isolate it doesn't contain lactose.

Even if you never had a reaction to lactose maybe now that you're having so much of it you're noticing the reaction.

I would call my doctor on the weekend. I never heard of a doctor not having someone on call.
