GLP-1s for Weight Loss: What You Need to Know
What are GLP-1s?
In recent years, GLP-1 receptor agonists (GLP-1s) have gained significant attention for their role in weight loss. Originally developed to treat type 2 diabetes, these medications have shown impressive results in helping people lose weight. With high-profile endorsements and increasing availability, GLP-1s are changing the landscape of obesity treatment.
GLP-1 (glucagon-like peptide-1) receptor agonists are a class of medications that mimic the natural GLP-1 hormone in the body. This hormone is released after eating and helps regulate blood sugar, slow digestion, and reduce appetite. By enhancing these effects, GLP-1s help people eat less and feel fuller for longer, leading to weight loss. Some of the most well-known GLP-1 medications include:
Semaglutide (Ozempic, Wegovy)
Liraglutide (Saxenda, Victoza)
These drugs are typically taken as a weekly or daily injection, depending on the specific medication.
How Do GLP-1s Work for Weight Loss?
GLP-1s contribute to weight loss in several ways:
1. Reducing Appetite
They slow stomach emptying and send signals to the brain that reduce hunger.
2. Reducing Appetite
Many users report fewer cravings, especially for high-calorie, sugary foods.
3. Regulating Blood Sugar
By improving insulin sensitivity and reducing blood sugar spikes, they help prevent energy crashes that can lead to overeating.
3. Affecting the Brain’s Reward System
Some research suggests GLP-1s may reduce the brain’s response to food rewards, leading to healthier eating habits.
How Effective Are GLP-1s for Weight Loss?
Studies have shown that GLP-1s can lead to significant weight loss, especially when combined with a healthy diet and exercise.
Semaglutide (Wegovy): Clinical trials showed an average weight loss of 15% of body weight over 68 weeks.
While these results are impressive, individual experiences vary, and not everyone will achieve the same level of weight loss.
Who Can Benefit from GLP-1s?
GLP-1 medications are generally prescribed for:
- People with obesity (BMI ≥30)
- People who are overweight (BMI ≥27) with weight-related health conditions like diabetes, high blood pressure, or sleep apnea
- Those struggling with sustainable weight loss through lifestyle changes alone
However, they are not recommended for people with a history of certain thyroid cancers, pancreatitis, or severe gastrointestinal issues.
Potential Side Effects and Risks
While GLP-1s are effective, they can come with side effects, especially when first starting the medication. Common side effects include:
- Nausea (most common)
- Vomiting or diarrhea
- Constipation
- Fatigue
- Mild stomach pain
- Pancreatitis is a rare but serious side effect which we closely monitor patients for
Most side effects improve over time, but some people experience more severe complications like gallbladder issues or pancreatitis. It’s important to discuss potential risks with a healthcare provider before starting treatment.
Cost and Accessibility
GLP-1 prices are thankfully relatively inexpensive affordable in the UK in comparison to other countries such as USA where they can cost 5 times as much. The health benefits and cost benefits of weight loss often need to be balanced against the costs of Wegovy injections.
In most cases these are favourable.We aim to provide our patients with the best possible prices which include Wegovy pens issued along with in person appointments for clinical assessment and monitoring.
Do GLP-1s Work Long-Term?
One challenge with GLP-1 medications is that weight can return after stopping them.
Studies show that many people regain a significant portion of lost weight once they discontinue treatment, suggesting that long-term use may be necessary for sustained results.
To maintain weight loss, it’s essential to focus on lifestyle changes, including:
- Healthy eating habits
- Regular exercise
- Behavioural strategies for long-term success
Are GLP-1s Right for You?
If you’re struggling with weight loss and considering GLP-1s, talk to your doctor about whether they’re a good fit. They’re not a magic bullet, but for many, they provide a powerful tool for achieving and maintaining a healthier weight.
As research continues and newer medications emerge, GLP-1s are shaping the future of weight management. Whether you’re exploring options or already using one of these treatments, staying informed is key to making the best decision for your health.
