Has anyone else had a rash after surgery. I am about 4 months post-op and no real problems, and suddenly this rash develops ands spreads all over. I looked up online and found something called “keto rash” caused by high protein, low carb diet. I have now seen 3 doctors, including a dermatology consult at university hospital, and they think this is a reaction to taking Prilosec (which my Bariatric doctor prescribed). I won’t know for sure until some skin samples (biopsied) come back. I also have a history of eczema, and think this might just be a bad outbreak (triggered by the “stress” of surgery and lifestyle change). Has anyone else heard of Keto rash or had it?
