The journey to bariatric surgery begins well before the procedure. Understand the steps: from diet adaptation to medical consultations, each detail is crafted to maximize the safety and effectiveness of your transformation. Pre-operative preparation optimizes safety and surgical outcomes. Patients are often asked to lose a small amount of weight before the surgery. A series of tests, including gastrointestinal endoscopy, abdominal ultrasound, and various laboratory tests, are also conducted. Laboratory tests should be carried out periodically to monitor the patient's nutritional status.

First Stage: The Liquid Diet

The liquid diet can last from 1 to 3 weeks. Foods must be completely liquid, and in the first 48 hours, they should be clear, consumed in small volumes (50ml) and slowly. This may be the most challenging phase of the diet.

The multidisciplinary team provides individual guidance on the intake of dietary supplements. Generally, the advice is to consume chewable multivitamins to ease swallowing. The consumption of isolated whey protein (milk serum protein) is also essential in this phase.

Second Stage: The Puréed Diet

The Puréed diet lasts typically from 10 to 20 days. Small portions of food with the consistency of puree or pudding support your nutrition. Supplementation and hydration continue to be the pillars of your recovery, adapting to your new digestive capacity.

The recommendation for dietary supplements (chewable tablets and whey protein) is usually maintained during this stage.

Third Stage: The Soft Diet

This is the time to reacquaint yourself with chewing, with a diet that includes cooked salads, well-cooked fresh meats, and vegetables.

The multidisciplinary team provides individual guidance on the intake of dietary supplements.

In this phase, if the patient has good swallowing ability, the form of the multivitamin can be changed to softgel capsules, capsules, or tablets.

Fourth Stage: The Stabilization Diet

A diet where most foods are allowed. Nutritional guidance remains crucial to ensure smart food choices, staying away from processed foods high in fats and sugars.

Daily supplementation continues to be essential to complement your diet with key nutrients: proteins, vitamin A, vitamin D, vitamin B1 and B12, calcium, and iron.

Nutritional Follow-Up

The nutritionist plays a key role in monitoring the patient throughout their bariatric journey, offering vital support in clinical treatment, pre-operative evaluations, and post-operative care. They provide personalized nutritional plans tailored to each patient's needs, helping to manage dietary changes and ensure proper nutrient intake.

Nutritional re-education is crucial, extending beyond weight loss to encompass long-term weight management and overall health maintenance. It involves teaching patients about healthy food choices, portion control, and the importance of a balanced diet to prevent nutritional deficiencies and support a sustainable, healthy lifestyle after surgery.

Preparation for bariatric surgery involves follow-up by a multidisciplinary team, including a nutritionist, endocrinologist, cardiologist, psychologist, and speech therapist. They will guide you on significant lifestyle changes, such as adopting a healthy diet and including physical exercises in your daily routine.

Before the surgery, various tests are required, such as laboratory analyses, abdominal ultrasonography, digestive endoscopy, and chest radiography, to ensure that you are in adequate condition for the procedure.

The nutritionist will provide detailed guidelines on the pre-operative diet, which may include caloric restrictions for weight loss. The focus will be on a healthy and balanced diet.

The medical team will inform you about medications to be avoided, such as aspirin, ginkgo biloba, contraceptives, and hormone replacement therapies. This guidance is crucial to minimize risks during and after the surgery.

Psychological consultation is vital to assess the patient's mental readiness for surgery. The psychologist investigates possible eating disorders, behavioral issues, substance use, and conditions like depression and anxiety, determining the patient's fitness for the procedure.

In the first days after bariatric surgery, the diet should be strictly liquid, lasting from 1 to 3 weeks. Initially, the liquid foods should be clear and consumed in small volumes (approximately 50ml) and slowly to avoid discomfort. Supplementation is a crucial part of this phase, with the multidisciplinary team generally recommending chewable multivitamins and whey protein to ensure adequate nutrition during recovery.

Resuming physical activities can usually occur after 60 days of surgery. However, it is crucial to follow the guidance and assessments of the medical team to ensure that activities are resumed safely and beneficially for the recovery process and health maintenance.
