What is Wegovy? Everything you need to know

Wegovy For Weight Loss - Everything You Need To Know

When looking into weight loss medication options, it can be quite difficult to figure out which is best for you, especially with all of the many choices that are available on the market at the moment. One of the newest options on the market at the moment is Wegovy, an injectable form of weight loss medication designed to help decrease your appetite and therefore eat less, resulting in weight loss. 

How does Wegovy work? 

Wegovy functions by imitating the hormone GLP-1 (glucagon-like peptide-1). This naturally occurring hormone helps in:

  • Regulating Blood Sugar: By stabilising your glucose levels, the medication can assist those with conditions like type 2 diabetes.

  • Reducing Appetite: GLP-1 sends signals to your brain to make you feel fuller for longer, thus helping you consume fewer calories.

As a result, users of the medication often end up in a calorie deficit, which results in weight loss when maintained overtime.

How do you take Wegovy?

Like Saxenda, another weight loss injection, Wegovy is administered through:

  • Location: Injections are commonly done in the stomach, thigh, or upper arm.

  • Frequency: You’ll need one injection per week.

  • Dosage: Wegovy comes in pre-filled pens with varying doses from 0.25 mg to 2.4 mg.

How effective is Wegovy? 

Many studies have been carried out to determine the efficacy of Wegovy for weight loss. One of the most recent studies into the drug found that people who took the drug for a period of 68 weeks alongside diet and exercise saw a 15% reduction in body weight, compared to just 2.4% for those who took placebo.

For example, individuals who weigh 20 stone when they start taking Wegovy could expect a 3 stone weight loss in the first 16 months. Given this is just an average and other factors, such as diet and exercise, also come into play, the amount of weight lost can vary. 

Who can take Wegovy? 

Wegovy is advised for:

  • Adults: With a BMI of 30+ or 27+ if they have weight-related issues like type 2 diabetes, hypertension, or high cholesterol.

  • Children: Aged 12 and above with a BMI at the 95th percentile or greater for their age and sex.

Who should not take Wegovy? 

Not everyone can safely use this medication. You should avoid Wegovy if you:

  • Have a history of Medullary Thyroid Carcinoma or Multiple Endocrine Neoplasia syndrome type 2.
  • Have had severe allergic reactions to semaglutide or any other ingredient in Wegovy.
  • Are pregnant, planning on a pregnancy or are currently breastfeeding.

Before using Wegovy, it’s important to tell your GP or pharmacist if you have or have ever experienced any of the following medical conditions:

  • Depression, suicidal thoughts, or other mental health issues.

  • Type 2 diabetes and a history of diabetic retinopathy.

  • Issues with the pancreas or kidneys.

Be sure to tell your healthcare provider about any medicines you’re currently taking before starting Wegovy, as it can have an effect on the way certain medications and supplements work and other medications can impact Wegovy’s efficacy too.
