Wegovy, a prescription weight loss medication, has gained attention for its effectiveness in helping adults and children with obesity or overweight shed excess pounds. This injectable form of semaglutide works by mimicking a hormone that targets areas of the brain involved in appetite regulation.

Clinical studies have shown that Wegovy can lead to significant weight loss when combined with reduced calorie intake and increased physical activity. The medication is typically administered once a week, with dosage gradually increased over time to minimize side effects.

While Wegovy offers promising results for many individuals struggling with weight management, it’s important to consider factors such as cost, potential side effects, and long-term sustainability. As with any medical treatment, consulting a healthcare professional is crucial to determine if Wegovy is an appropriate option for one’s specific health needs and circumstances.

Understanding Wegovy

Wegovy is a prescription medication for weight loss that works through weekly subcutaneous injections. The active ingredient semaglutide mimics a naturally occurring hormone to regulate appetite and food intake.

What Is Wegovy?

Wegovy is an FDA-approved injectable medication for chronic weight management. It’s prescribed to adults with obesity (BMI ≥30) or overweight (BMI ≥27) with at least one weight-related comorbidity. Wegovy comes in a pre-filled pen for once-weekly subcutaneous injections.

The medication is used alongside a reduced-calorie diet and increased physical activity. Clinical trials have shown significant weight loss results in many patients using Wegovy compared to placebo groups.

The Active Ingredient: Semaglutide

Semaglutide is the active ingredient in Wegovy. It belongs to a class of drugs called glucagon-like peptide-1 (GLP-1) receptor agonists. Originally developed to treat type 2 diabetes, semaglutide was found to be effective for weight loss at higher doses.

The drug is a synthetic version of the human GLP-1 hormone. It has a long half-life, allowing for once-weekly dosing. Semaglutide works by mimicking the effects of GLP-1 in the body, influencing appetite regulation and food intake.

Mechanism of Action

Wegovy works by targeting areas of the brain involved in appetite regulation and food intake. It binds to and activates GLP-1 receptors, mimicking the effects of the natural GLP-1 hormone.

This activation leads to:

• Increased feelings of fullness
• Reduced hunger sensations
• Slowed gastric emptying

By influencing these processes, Wegovy helps patients consume fewer calories, leading to weight loss over time. The medication also affects the reward centers in the brain, potentially reducing food cravings.

GLP-1 Receptor Agonist Explained

GLP-1 receptor agonists are a class of medications that mimic the action of the naturally occurring GLP-1 hormone. GLP-1 is produced in the intestines and plays a role in glucose metabolism and appetite regulation.

Key effects of GLP-1 receptor agonists include:

• Stimulating insulin release
• Suppressing glucagon secretion
• Slowing gastric emptying
• Promoting satiety

In the context of weight loss, the appetite-suppressing and satiety-promoting effects are particularly important. By activating GLP-1 receptors, Wegovy helps patients feel full faster and for longer periods, naturally reducing calorie intake.

Indications and FDA Approval

Wegovy has received FDA approval for multiple uses in adults. The medication targets obesity, cardiovascular risks, and weight-related health issues through weekly injections.

Approved Uses for Adults

The FDA has approved Wegovy for chronic weight management in adults with obesity or overweight with at least one weight-related comorbidity. It is prescribed alongside a reduced-calorie diet and increased physical activity. In March 2024, the FDA expanded Wegovy’s approval to include cardiovascular risk reduction. This new indication allows its use to lower the risk of major cardiovascular events like heart attack, stroke, and death in adults with established cardiovascular disease who are obese or overweight.

Wegovy and Type 2 Diabetes

While Wegovy is not specifically approved for treating Type 2 diabetes, it may benefit patients with this condition who are also managing their weight. The medication’s active ingredient, semaglutide, is known to improve glycemic control. However, for diabetes management, different formulations and dosages of semaglutide are used. Patients with Type 2 diabetes considering Wegovy should consult their healthcare provider to discuss potential benefits and risks in the context of their overall treatment plan.

Administration of Wegovy

Wegovy is administered as a subcutaneous injection using a pre-filled pen. Proper technique, dosing, and storage are crucial for optimal results and safety.

How to Inject Wegovy

To administer Wegovy, select an injection site on the abdomen, thigh, or upper arm. Clean the area with an alcohol wipe. Remove the pen cap and check that the medication is clear and colorless. Place the pen against the skin at a 90-degree angle and press the injection button until you hear a click.

Hold the pen in place for 6 seconds to ensure the full dose is delivered. Remove the pen and dispose of it properly. Rotate injection sites weekly to prevent tissue changes.
