The rise of injectable weight loss treatments The rise of injectable weight loss treatments

There has been a growing interest in injectable weight loss treatments as an alternative or complement to traditional weight loss methods. One such treatment that has gained significant attention is Wegovy (semaglutide) for chronic weight management. However, Wegovy is just one of several injectable options available or under development. 

In this article, we will explore injectable weight loss treatments, including how they work, their effectiveness and what the future may hold for this evolving field.

Understanding Injectable Weight Loss Treatments

Injectable weight loss treatments typically fall into two categories: those that target the gut hormones to reduce appetite and those that act on the central nervous system to suppress appetite and increase metabolism.

  • Gut Hormone Targeting Treatments: Semaglutide, the active ingredient in Wegovy, belongs to a class of drugs known as glucagon-like peptide-1 (GLP-1) receptor agonists. GLP-1 is a hormone that regulates appetite and food intake. By mimicking the effects of GLP-1, semaglutide helps reduce hunger and calorie intake, leading to weight loss.
  • Central Nervous System Targeting Treatments: Other injectable treatments, such as liraglutide (Saxenda) and bupropion/naltrexone (Contrave), target the central nervous system to regulate appetite and increase metabolism. These medications work by altering the activity of neurotransmitters in the brain involved in appetite control.

Benefits of Wegovy Injection in Weight Loss

Wegovy injection, containing the active ingredient semaglutide, offers several benefits for individuals struggling with obesity or overweight:

  1. Effective Weight Loss
  2. Appetite Control
  3. Improved Metabolic Health
  4. Convenience
  5. Potential Long-Term Benefits

Effective Weight Loss

Clinical trials have shown that Wegovy can lead to significant weight loss when combined with a reduced-calorie diet and increased physical activity. Patients taking Wegovy experienced an average weight loss of around 15% of their initial body weight over a year, compared to 2-4% with a placebo. 

Appetite Control

Wegovy works by mimicking the effects of the natural hormone GLP-1, which helps regulate appetite and food intake. By activating GLP-1 receptors in the brain, Wegovy helps reduce hunger and calorie intake, making it easier for individuals to stick to their diet and lose weight.

Improved Metabolic Health

In addition to weight loss, Wegovy has been shown to improve metabolic health markers such as blood sugar levels, cholesterol levels and blood pressure. These improvements can help reduce the risk of developing obesity-related conditions such as type 2 diabetes and cardiovascular disease.


Wegovy is administered once weekly via a subcutaneous injection, making it a convenient option for individuals who may struggle with daily medication regimens. This weekly dosing schedule can also help improve treatment adherence.

Potential Long-Term Benefits

Studies suggest that the weight loss achieved with Wegovy may be sustainable over the long term, leading to continued improvements in health and quality of life.

How to Take Wegovy: The Best Practices

Taking Wegovy involves several best practices to ensure its effectiveness and minimise potential side effects. Here's a guide on how to take Wegovy:

  • Consultation with our Healthcare Provider: Before starting Wegovy, it is essential to consult with our healthcare provider. We will evaluate your medical history, current medications and weight loss goals to determine if Wegovy is the right choice for you.
  • Prescription and Dosage: Wegovy is available by prescription only. Your healthcare provider will prescribe the appropriate dosage based on your individual needs. The standard dosage is 2.4 mg once weekly, administered as a subcutaneous injection.
  • Injection Technique: Wegovy is injected under the skin (subcutaneously) in the abdomen, thigh or upper arm. It is important to rotate injection sites to prevent irritation or lipodystrophy (a condition characterised by a loss of fat tissue) at the injection site.
  • Timing of Injections: Wegovy should be taken once weekly on the same day each week. It can be taken at any time of day, with or without food. Consistency in timing is key to maintaining a steady level of the medication in your body.
  • Diet and Exercise: While taking Wegovy, it is important to follow a reduced-calorie diet and engage in regular physical activity. These lifestyle changes are essential for maximising the effectiveness of Wegovy and achieving your weight loss goals.
  • Monitoring: Your healthcare provider will monitor your progress regularly while taking Wegovy. They may adjust your dosage or recommend additional interventions based on your response to treatment.
  • Side Effects: Common side effects of Wegovy include nausea, vomiting, diarrhea and constipation. These side effects are usually mild and improve over time. If you experience severe or persistent side effects, contact your healthcare provider.
  • Precautions: Wegovy is not recommended for use in individuals with a personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2). It is also not recommended for use in individuals with a history of pancreatitis.
  • Pregnancy and Breastfeeding: It is not known if Wegovy can harm an unborn baby or pass into breast milk. If you are pregnant, planning to become pregnant or breastfeeding, discuss the risks and benefits of Wegovy with your healthcare provider.
  • Storage: Wegovy should be stored in the refrigerator. If stored outside, the temperature must be between 46°F to 86°F and for up to 28 days.

Future Developments

The field of injectable weight loss treatments is rapidly evolving, with several new medications in development. One promising candidate is tirzepatide, a dual glucose-dependent insulinotropic polypeptide (GIP) and GLP-1 receptor agonist. Early clinical trials have shown promising results, with patients experiencing significant weight loss and improvements in metabolic health.

Another area of research is the development of combination therapies that target multiple pathways involved in appetite regulation. For example, researchers are investigating combinations of GLP-1 receptor agonists with other medications, such as amylin analogs or opioid receptor antagonists, to enhance weight loss effects.
