Maintaining a healthy weight is important for overall well-being. While diet and exercise are the best ways to manage weight, some people need extra help. Prescription weight loss injections are an option for those struggling to lose weight through traditional methods. This guide covers how they work, their benefits, risks, and effectiveness.

What Are Prescription Weight Loss Injections?

These are medications given as injections to help with weight loss. They work by controlling appetite, slowing digestion, or affecting how the body processes food. Doctors prescribe them for people who meet certain health conditions, such as obesity or weight-related issues like diabetes.

How Do They Work?

Weight loss injections target different functions in the body. Some affect hormones that control hunger, making you feel full longer. Others help regulate blood sugar levels, preventing energy crashes that lead to cravings. Some injections slow down digestion, so food stays in the stomach longer, reducing hunger.

Common Types of Prescription Weight Loss Injections

Semaglutide (Wegovy, Ozempic) – This injection mimics a natural hormone that helps control appetite and blood sugar levels. It is approved for long-term weight management.

Liraglutide (Saxenda) – This medication works by slowing digestion and reducing hunger. It is prescribed for adults and some teens with obesity.

Tirzepatide (Mounjaro) – This injection affects multiple hormones that regulate hunger and blood sugar.

Who Can Use These Injections?

Doctors prescribe these injections for people who meet specific criteria. Generally, they are for adults with:

- A Body Mass Index (BMI) of 30 or higher (classified as obesity)

- A BMI of 27 or higher with health issues like diabetes or high blood pressure

- A medical history showing difficulty losing weight through diet and exercise alone

These medications are not for people who are pregnant, breastfeeding, or have certain health conditions.

Supports Sustainable Weight Loss – Many users experience gradual weight loss when combined with a healthy diet and exercise.

Possible Risks and Side Effects

Fatigue – Some users feel tired as the body adjusts to the medication.

Risk of Low Blood Sugar – People with diabetes need to monitor their blood sugar levels closely.

Serious side effects are rare but can include allergic reactions or inflammation of the pancreas. It is important to follow the doctor’s advice and report any concerning symptoms.

How Effective Are They?

Studies show that prescription weight loss injections help many people lose weight when combined with a balanced diet and regular exercise. Results vary, but some users lose up to 15% of their body weight over time.

To get the best results, these injections should be part of a long-term weight management plan that includes:
