How Much Weight Can I Expect to Lose After Gastric Bypass?

Getting gastric bypass in Phoenix, Arizona is a major step towards realizing your weight loss goals. But before you sign up for surgery, there is something you need to know: how much weight should you expect to lose?

There is no straightforward answer to this question. The weight you lose will be quite different from another patient, even if they are similar in BMI and overall health to you. Let’s take a look at why this is.

How Much Weight Can I Expect to Lose After Gastric Bypass?

Average Weight Loss With Gastric Bypass

The first thing you need to know is what the average weight loss is for patients who have received gastric bypass surgery. At the one-year mark, this is about 50% of their excess weight.

Of course, for this to be meaningful, you need to understand what excess weight is. Essentially, you have an ideal body weight based on your height, age, gender, and overall build. So, if a patient’s current weight is 300 pounds and their ideal weight is 125 pounds, their excess weight is 175 pounds.

Going off the averages, this means that by the end of the first year, this patient is likely to lose somewhere in the range of 87.5 pounds.

Why Averages Are Not Rules

It’s math we all learned in school; to get the average, you add up the group of numbers, then divide the total by how many numbers you added. This means that the average of 50% of excess weight lost after 12 months represents many people who fell outside that 50% range—even well outside of it.

The good news is that you could be one of those who fall somewhere around 50% of excess weight lost or more. And you have quite a bit of control over how much weight you lose.

Factors Impacting Weight Loss After Gastric Bypass

Why is there such a spread with weight loss after getting gastric bypass? It’s because there are multiple factors that determine how fast you drop pounds and how many in total you shed. These include:

  • How your body naturally responds to the procedure.
  • Following the post-op diet.
  • Eating healthy after entering the solid food stage of the gastric bypass weight loss timeline.
  • Being generally active.
  • Following an exercise regimen.

It should also be noted that weight loss after gastric bypass surgery ebbs and flows. For example, how much weight you lose the first month after gastric bypass is usually 30 pounds, but this slows down as you start eating solid foods. And while weight loss continues after the first year, you’ll drop significantly fewer pounds.
