Weight Loss Injection Pen

Weight loss injection pens contain GLP-1 receptor agonist medications, such as semaglutide — a clinically proven option for weight management. Research shows that individuals may lose an average of 15% of their body weight, with about 30–35% losing 20% or more. Semaglutide has also been shown to lower the risk of heart attacks and strokes, particularly in people who are overweight or obese and have existing cardiovascular risk factors.

  • Promotes sustained weight loss in individuals who are overweight or obese
  • Reduces the risk of cardiovascular events, even in those without diabetes
  • Weight loss in adults with a high BMI or obesity-related health conditions

How It Works

Semaglutide mimics a natural hormone in the body known as GLP-1, which influences appetite and digestion.

  • Suppressing appetite via the brain’s hunger centre (the hypothalamus)
  • Slowing gastric emptying, helping you feel full for longer
These effects help reduce food intake and support long-term weight management.

  • BMI is 27 or higher, or
  • BMI is 23 or higher with medical conditions such as diabetes, high blood pressure, or high cholesterol
Some individuals may notice changes within the first month, with more visible improvements typically seen by month three or four. Consistency is key — sustained results take time.
The injection is administered once a week using a pre-filled pen. The pen should be stored in the refrigerator.
Serious (but uncommon) side effects include:
  • Pancreatitis (inflammation of the pancreas)
  • Gallbladder problems, such as gallstones or cholecystitis
Common side effects may include:
  • Nausea
  • Bloating
  • Diarrhoea
  • Fatigue
  • Low blood sugar (especially if taken with other diabetes medications)
Yes — the injection is typically self-administered once a week, usually in the abdominal area.
Most people find it relatively painless, often rating it 1–2 out of 10 on a pain scale.
Some individuals, especially those prone to pigmentation, may notice faint marks at the injection site.
  • Engage in regular exercise (aim for at least 3 times a week)
  • Maintain a healthy diet, with more fruits, vegetables, and balanced meals
  • Address underlying psychological factors — for example, if binge eating or poor sleep is a concern, consider seeing a psychiatrist for medications or a psychologist for therapy (such as CBT) to support better habits and mental well-being

Evidence suggests that weight may return once the medication is stopped. For sustained results, long-term use may be recommended.
