Who should consider weight-loss medication?
Weight-loss medicines may be considered for selected people with obesity or overweight with weight-related health problems, alongside lifestyle treatment.
The decision depends on the individual's health and risks.
Do weight-loss medicines work?
Several modern medicines can produce meaningful weight loss when appropriately prescribed.
The response varies between individuals.
What are GLP-1 medicines?
GLP-1 receptor agonists mimic the action of a natural hormone involved in appetite, digestion and glucose regulation.
They can reduce appetite and help with weight loss.
What is tirzepatide?
Tirzepatide acts on both GIP and GLP-1 receptors.
It can improve glucose control and produce substantial weight loss in appropriate patients.
Are weight-loss injections safe?
They can be safe when appropriately prescribed and monitored, but they can also cause side effects and are not suitable for everyone.
Do weight-loss injections cause muscle loss?
Weight loss can include some loss of lean mass.
Nutrition, adequate protein and resistance exercise are important during treatment.
Do I have to take weight-loss medicines forever?
Obesity is a chronic condition and weight regain can occur after treatment is stopped.
The duration of treatment should be individualised.
Can I take weight-loss injections without seeing a doctor?
It is better to have medical assessment first.
The correct medicine, dose and treatment duration depend on your medical history, other medicines and health conditions.
