Gastric Sleeve Weight Loss Surgery: What to Expect in the First 3 Weeks

West Texas Bariatrics Patient Standing on Scale

Everyone will undergo some life changes after gastric sleeve surgery, especially in the first three weeks. First, it’s important to understand what this surgery is and how it works. Gastric sleeve surgery is a minimally invasive procedure and involves the removal of a portion of the stomach, resulting in a smaller stomach pouch. The reduced stomach capacity helps control food intake, leading to reduced calorie consumption and weight loss over time. Also, the levels of the hormone ghrelin, which regulates your hunger, are reduced, which means that you’ll have fewer cravings. 

The First Three Weeks After Surgery

The first three weeks following gastric sleeve surgery are a critical phase in the recovery and weight loss journey. During this time, the body is adjusting to the changes, and weight loss usually occurs at a relatively rapid rate.

In the immediate postoperative period, individuals normally experience significant weight loss due to a combination of factors. The main factor is that the restricted stomach capacity limits food intake, and the body begins to tap into stored fat reserves for energy. This, along with following a postoperative diet and exercise, means that the initial weight loss can be quite substantial.

Average Weight Loss

While there is no set number that applies to everyone, studies and clinical observations have provided some insights into the average weight loss during the initial three weeks after gastric sleeve surgery. On average, individuals can expect to lose around 10-20% of their excess body weight during this period. For example, if someone has 100 pounds of excess weight, they might lose 10-20 pounds within the first three weeks of gastric sleeve surgery.

Individual Variations

It’s important to note that weight loss patterns and rates can vary significantly among individuals. Factors such as starting weight, body composition, metabolism, adherence to postoperative guidelines, and overall health can influence the rate and amount of weight lost. Each person’s journey is unique, and individual results may differ.

Factors Affecting Weight Loss After Gastric Sleeve Surgery

Several factors can influence weight loss outcomes after gastric sleeve surgery. These include:

Adherence to Dietary Guidelines: Following the recommended postoperative diet, which typically consists of gradually transitioning from liquids to soft foods and then solid foods, is crucial for optimal weight loss. Avoiding alcohol is also a crucial requirement after undergoing bariatric surgery.

Physical Activity: Incorporating regular physical activity as advised by the healthcare team can help accelerate weight loss and improve overall fitness.

Individual Differences: As mentioned earlier, individual variations play a significant role. Factors like metabolism, starting weight, and overall health can impact the rate and amount of weight lost.

Gastric sleeve surgery can lead to substantial weight loss and improved health outcomes for individuals struggling with obesity. While the average weight loss in a three-week period after surgery varies, it is typically around 10-20% of excess body weight. However, it’s important to remember that everyone’s journey is unique, and individual results may differ based on various factors. Working closely with your healthcare team, following postoperative guidelines, and adopting healthy lifestyle habits will contribute to successful and sustainable weight loss in the long run.
