Weight gain increases the risk of health problems like stroke, high blood pressure, high cholesterol, and certain cancers, making weight loss crucial. Bariatric surgeries, including Single Anastomosis Duodenal Switch (SADI or SIPS), are an effective solution to lose weight. After the procedure, patients need to take extra care of themselves and follow a healthy diet plan to ensure faster recovery. You need to consult experienced bariatric surgeons who can craft a personalized post-op care and diet plan. Residents of Dallas and Fort Worth considering the SADI procedure can consult DFW Bariatrics & General Surgery. In this blog, we present a typical post-op diet plan for SADI patients.

Clear Liquid Diet – Week 1

Immediately following surgery, patients are advised to follow a clear liquid diet, which includes water, non-acidic fruit juices, decaffeinated tea/coffee, protein drinks, soups, and fat-free milk. The primary goal of this clear liquid diet is to maintain hydration during the healing process. This diet may last for one week after the surgery or longer, depending on the patient’s individual condition. To progress through each stage successfully, patients should not experience vomiting, diarrhea, bloating, nausea, or abdominal pain.

Full Liquid Diet – Week 2

During the second week, or upon successful completion of the first stage, patients advance to the second stage of the diet: the full liquid diet. This stage typically lasts for a minimum of five days and a maximum of fourteen days. Patients may consume foods with a smooth consistency, such as pureed soft fruits, cooked vegetables, and egg whites, in addition to water and other allowed liquids.

Puree Food – Week 3-4

The third stage of the diet is the pureed food/semi-solid food stage, which commences during the third week after surgery or upon completion of the second stage. Based on the patient’s tolerance during the first two stages, doctors recommend incorporating healthy fats and small portions of vegetables and fruits. Thoroughly chewing food is essential to prevent stomach irritation, vomiting, and nausea. If any of these symptoms arise, patients should consult their doctor immediately.

Solid Food – Week 5 and beyond

The fourth and final stage of the diet involves solid food consumption, which begins after successfully completing the third stage and continues for life. Patients should gradually transition to a healthy, balanced diet that incorporates fresh fruits, meats, and vegetables. Overeating or consuming inappropriate foods may lead to complications after surgery. To achieve optimal results, it is important to avoid high-calorie and high-fat foods.
