I’m 3.5 weeks post op sleeve and my surgeon’s plan doesn’t allow for raw vegetables until like week 8. I’ve had raw onions in a tuna salad and tomatoes (tech. a fruit) Those have been great.
you want steamed/well cooked and soft veggies like squash, carrots, cucumbers, celery and zucchini and all peeled with the skin off. And in first three weeks, puréed or soft enough that you can really chew them into a mash before swallowing.
each surgeon calls for a different plan of course and everyone reacts differently.
