Are Weight Loss Injections Safe? – Trusted Weight Loss Advice in Bishops Stortford
Weight loss injections have become increasingly popular in the UK, offering a medical approach to weight management for people who struggle to lose weight through diet and exercise alone. As interest grows, many people ask an important question: are weight loss injections safe?
At J E Williamson Pharmacy in Bishops Stortford, we provide professional guidance and access to trusted weight loss treatments. This blog explores how weight loss injections work, their safety profile, potential side effects, and whether they may be suitable for your goals.
What Are Weight Loss Injections?
Weight loss injections are prescription treatments designed to support appetite control, reduce cravings, and help regulate blood sugar levels. The most commonly used options in the UK include GLP-1 medications such as:
—> Mounjaro (tirzepatide)
—> Wegovy (semaglutide)
—> Saxenda (liraglutide)
These injections mimic natural hormones in the body that regulate appetite and digestion. By helping you feel fuller for longer and reducing hunger, they support more consistent calorie control.
Are Weight Loss Injections Safe?
Yes — when prescribed by a qualified healthcare professional and used correctly, weight loss injections are considered safe for eligible patients. These treatments have undergone extensive clinical studies and are approved by regulatory bodies such as the MHRA.
However, they are not suitable for everyone. Weight loss injections must only be used under medical supervision to ensure they are appropriate for your health profile.
Who Are They Suitable For?
Weight loss injections are usually recommended for adults who:
—> Have a BMI of 30 or above
—> Have a BMI of 27 or above with weight-related health conditions
—> Have struggled to lose weight despite lifestyle changes
A consultation is essential so your pharmacist or prescriber can assess your medical history, medications, and overall suitability.

Safety and Side Effects
Like all medications, weight loss injections can cause side effects. Most are mild, temporary, and occur during the first few weeks of treatment as your body adapts.
Common Side Effects
—> Nausea
—> Vomiting
—> Bloating or indigestion
—> Constipation or diarrhoea
—> Decreased appetite
These effects typically settle over time. Starting with a low dose and increasing gradually helps minimise discomfort.
Less Common Side Effects
—> Headaches
—> Fatigue
—> Injection site irritation
—> Dizziness
Serious side effects are rare but can occur. That’s why weight loss injections should only be used with guidance from a healthcare professional who can monitor your progress and adjust treatment if needed.
If you experience persistent or troubling side effects, contact our pharmacy team for advice and support.
How Effective Are Weight Loss Injections?
Weight loss injections have been shown to produce significant and sustainable weight loss when combined with healthy lifestyle changes. Clinical trials show that many patients achieve:
—> Reduced appetite and cravings
—> Improved portion control
—> Better blood sugar stability
—> Consistent, long-term weight loss
Results vary depending on dosage, starting weight, activity levels, and individual metabolic factors.
The Importance of Professional Monitoring
