How Does Gastric Sleeve Surgery Affect the Hunger Hormone Ghrelin?

Ghrelin is often referred to as the “hunger hormone” because it plays a major role in regulating appetite and hunger. Ghrelin levels increase before meals and decrease after meals. This rise and fall of ghrelin are what makes us feel hungry before meals and satisfied after eating. But what happens to ghrelin levels after weight-loss surgery? In this article, we’ll explore how gastric sleeve surgery impacts the hunger hormone ghrelin.

What Happens to the Hunger Hormone (Ghrelin) After Gastric Sleeve Surgery?

Ghrelin levels are dramatically affected by gastric sleeve surgery. Immediately after the surgery, ghrelin levels drop significantly and remain low for several months. This decrease in ghrelin is one of the reasons why patients report feeling less hungry after gastric sleeve surgery. However, over time Ghrelin levels will slowly start to increase and return to pre-surgery levels. This can happen anywhere from six months to a year after surgery. When ghrelin levels start to increase, patients may start to feel hungry again. However, hunger after gastric sleeve surgery is often different than hunger before surgery. After surgery, patients tend to feel hungry more frequently but for shorter periods of time.

So, in this case, it is crucial to have a plan to deal with hunger. This may include avoiding trigger foods, eating smaller meals more often, or finding other ways to cope with hunger, such as distraction or deep breathing. Additionally, it will also help to know what medications to avoid after gastric sleeve surgery, as this may cause damage to your stomach lining and increase your risk for ulcers. Overall, it is important to be mindful of your diet and hunger levels after gastric sleeve surgery in order to maintain your weight loss.
