Ozempic is best known for its ability to help patients with type 2 diabetes control their blood sugar in combination with diet and exercise. It stimulates the pancreas to release insulin when glucose is present. It is also used to reduce the risk of major cardiovascular events, such as heart attack or stroke.

But the drug has also proven to be effective in helping those with obesity or overweight improve their metabolic health and lose weight. Obesity causes increased levels of fatty acids and inflammation, which leads to insulin resistance. This can turn into type 2 diabetes.

What is Ozempic?

Ozempic belongs to the drug class of medications called glucagon-like peptide-1 (GLP-1) and contains the active ingredient semaglutide.

Ozempic is not a weight loss drug on its own. It must be used in addition to lifestyle changes to maximize success and avoid weight regain. These include diet, exercise, sleep, and emotional health.

Incretins are released when food is consumed

A gastric inhibitory polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are the two main incretin hormones that are released from the gut into the bloodstream when food is ingested. They then stimulate the release of insulin from the pancreatic beta cells. This is called the incretin effect and is responsible for at least 50% of the total insulin secreted after you consume oral glucose or nutrients.

How Ozempic works

Ozempic works by imitating the incretin hormones produced naturally in your body when you eat food.

It slows down how fast your stomach empties food, called gastric emptying, and makes you feel full for longer. Increased satiety makes you feel less hungry and reduce cravings, causing you to eat less and lose more weight.

Who should use Ozempic

Ozempic is indicated for chronic weight management in patients with a body mass index (BMI) of more than 30 kg/m2.

How long does it take to lose weight on Ozempic?

Like any drug, this medication can produce different results from one person to the next and it’s not possible to predict how long it will take to lose weight on the medication.

Weight loss takes time, and you will see the best results when you combine Ozempic with a healthy diet and exercise. How much weight you lose depends on the dosage you are taking, for how long, and several other factors.

Ozempic has been shown to result in an average weight loss of 5% or more of body weight after one year of treatment.

It is also possible that the medication may not work for you, or you may not be able to tolerate the full dose due to side effects.
