I am a RnY, healing slowly post-surgery on September 5th, on Stage 2, 600-800 calories which is truly deficent for proper needs. My bariatric team knows, I see surgeon again on October 9th and am scheduled for an Exploratory EGD on October 12th, I am tolerating soups, broth, liquids but my pouch does not accept purees. Maybe a slight stricture, But that is a bypass problem, not only sleevers regularly encounter. Until you restart solid foods, I doubt you'll reach 1000 calories,but then i, too, am learning as I go. And I do take, viscerally multi-vites, B12 (sublingual) calcium citrate, magnesium and all ordered meds including Zofran. I am losing weight, 22 pounds post-surgery, which is glorious for a 72 year old metabolism, usually the same rate as a sick depressed sea slug, but anxious for more good times to roll.😜🎪📍🚩🎃
