Book a ConsultationBariatric surgery is a life-changing procedure. For many patients, it provides freedom from obesity, diabetes, hypertension, sleep apnea, and other weight-related health issues. But it is essential to understand that surgery alone is not enough.
Your new stomach pouch and digestive system require special care, especially in the first few months. What you eat, how you eat, the supplements you take, and the lifestyle habits you adopt will determine the long-term success of your surgery.
At our center, we not only perform the most advanced bariatric surgeries but also provide comprehensive aftercare programs that focus on diet, exercise, supplements, and emotional support.
This detailed guide will walk you through everything you need to know about post-operative diet, supplements, and lifestyle modifications after bariatric surgery.
After bariatric surgery, your stomach size is drastically reduced, and in some procedures, part of the intestine is bypassed.
This is why structured diet plans and lifelong supplements are non-negotiable after bariatric surgery.
The diet progresses slowly to allow your stomach to heal and adapt. Below is the structured approach followed at our practice.
Your stomach is very sensitive immediately after surgery. Clear fluids prevent dehydration without straining the stomach.
