Ate bacon and drank soda often after gastric bypass. Was I nutrient deficient?

What?? probably yes. Dear blake, i assume you have been seen and consulted with a nutritionist. Bariatric surgery is major surgery to hopefully help many chronic and sometimes severe medical - physicial conditions. Your digestive system has changed. I believe you have been given instructions on the specific foods/nutrients you need daily. Please review your instructions with your doctors/nutritionists they're to help.
