If you know firsthand what being overweight or obese is, you have likely already tried many different drugs for weight loss. Unfortunately, many of them are ineffective. But now there is an opportunity to say goodbye to the hated kilograms forever with the help of the new injectable drug Wegovy. How does Wegovy work in the body?

The active ingredient of the drug is Semaglutide. This substance simulates the natural human hormone GLP-1, which affects a specific part of the brain responsible for appetite and food intake. What does Wegovy do to your body? It makes you feel full no matter what or when you eat. As a result, you do not feel hungry and may refuse to eat. Consequently, you reduce the total calorie content, which, combined with exercise, contributes to effective weight loss.

How does Wegovy cause weight loss without exercise? Even if you are not a sports person, the drug will be effective by reducing your total daily caloric intake. In addition, while taking Wegovy, you should avoid fatty foods.

Does Wegovy work immediately? The drug begins to work immediately after its administration, but you will see the results only a few weeks after the start of treatment. You should strictly follow the instructions, lead an active lifestyle, and remove fats from your diet to improve Wegovy effectiveness.

Considering the Wegovy mechanism of action and possible side effects, doctors only prescribe the drug if the BMI is 27 or higher when it comes to obesity and overweight. Wegovy moa is to reduce appetite, which most often causes weight gain. In the absence of appetite, you do not want to eat, and your body begins to actively destroy fat deposits around the hips and abdomen. You lose weight and get healthier!

Does Wegovy speed up metabolism or not

Many ask: Does Wegovy increase metabolism? The drug has a different mechanism of action, but when taken regularly, it regulates metabolism, reducing insulin and blood sugar levels. That means your metabolic health improves.

Most importantly, you don’t have to force yourself to stop eating, which triggers the release of stress hormones like ghrelin and cortisol. You do not feel like eating, and losing weight is comfortable. And after the end of treatment, extra kilograms will not return to you, as is the case with strict diets and a sharp reduction in calories.

Does Wegovy start working right away, and when can you see the results

How long does it take for Wegovy to start working? If we talk about the effect of Semaglutide on the body, it begins immediately after an injection. But the results, such as reduced appetite and weight loss, appear a few weeks later. And sometimes, you can see the first results after a few months. How quickly does Wegovy start working? It largely depends on individual characteristics. So, do not hurry and continue treatment following the instructions. You will surely have the results!

The search for answers to the questions How fast does Wegovy start working? And How much weight can you lose? Gave the following results: for 68 weeks, the average weight loss was 15.9 kg, corresponding to approximately 15% of body weight. At the same time, 83% of those who took the drug reported positive results. Weight loss could begin as early as four weeks after starting treatment, but the full effect was noted after a few months.

Against the background of taking Wegovy, weight loss in the first month is usually insignificant since treatment begins with the minimum dosage of 0.25 mg. And then, every four weeks, you increase it to the maximum dosage of 2.4 mg. As a rule, you reach it by week 17. But there are cases when people lose much weight already in the first month of treatment. So, it is rather difficult to predict how fast you will begin to lose weight.
