Standard upper endoscopy is just looking around, taking biopsies, sucking Hydrochloric acid out of the stomach, and taking pictures
Btw, I am now 5 month on a 60 gram a day carbohydrate diet
My triglycerides came in at 44 (remember they didn't want to come down from 220), cholesterol 169, and HDL and LDL ok, but used to be better before tx. My fasting glucose is not budging though, steadfast at 96.
That tells me I need to remain on the ultra low carb diet.
