Have you ever wondered how those tiny building blocks in your body could help with weight loss? They’re simpler than you might think! These amazing molecules are like small chains made up of amino acids, which are basically the building blocks of proteins in our body. Think of them as a string of beads on a bracelet, where each bead is an amino acid. When about 50 of these amino acids join together, they form what we call a peptide. Our bodies are pretty incredible – they make various types of peptides naturally, including insulin, which helps control our blood sugar levels.
The Science Behind Peptide Medications
We know science talk can be confusing, so let’s break this down together! Scientists have been working hard in their labs to create peptides that can help us with different health issues. Some of the most exciting developments are medications called GLP-1 receptor agonists and combinations of GLP-1/GIP receptor agonists. Don’t worry about those fancy names – we’ll explain what they mean in simple terms!
Here’s something fascinating: these medications were actually first created to help people with type 2 diabetes. But researchers noticed something unexpected – people taking these medications started losing weight! It was like finding a hidden treasure and it opened up a whole new way to help people manage their weight.
How Peptides Work in Our Bodies
Let’s talk about how these peptides actually work in our bodies. Your body naturally makes hormones called GLP-1 and GIP (we call them incretin hormones). Think of them as your body’s natural helpers that do several important jobs:
- They tell your pancreas when to release insulin after you eat
- Help your liver control how much sugar it produces
- Make food stay in your stomach longer, so you feel full
- Signal your brain that you’re satisfied after meals
- Help control those pesky food cravings we all get
Types of Peptides for Weight Loss
Let’s explore the three main FDA-approved peptide medications that can help with weight loss. We’ll break down each one so you can understand exactly what they do and how they might help you on your weight loss journey.
- Wegovy: Your Weekly Weight Management Partner
Wegovy (let’s call it by it’s simple name instead of semaglutide) is like a weekly helper for your body. It’s designed for people dealing with weight management challenges and the best part is you only need to take it once a week!
Who can use Wegovy? Let’s make it simple:
- Adults with a BMI of 30 or higher
- Adults with a BMI of 27+ who have weight-related health issues like high blood pressure
- Young people (12 years and older) who are in the 95th percentile for their weight
- Saxenda: Your Daily Support System
Think of Saxenda as your daily companion in weight loss. While it works similarly to Wegovy, you’ll need to take it every day. We know daily medications can be part of your routine, just like taking vitamins or other daily supplements.
The interesting part about Saxenda is how it helps different groups of people. You might be a good candidate if:
- You’re an adult with a BMI of 30 or higher
- Your BMI is 27+ and you have health conditions related to weight
- You’re a teen (12 or older) weighing more than 132 pounds with a BMI of 30+
- Zepbound: The Newest Addition to Our Weight Loss Tools
In late 2023, we welcomed Zepbound to our weight loss medication family. What makes it special? It’s like having two helpers in one – it works with both GLP-1 and GIP receptors in your body. Think of it as a dynamic duo working together to help control your appetite and make you feel fuller longer.
Here’s what makes Zepbound unique:

Risks and Side Effects
Let’s be honest – all medications can have side effects and it’s important for us to understand what we might experience. Most people experience mild effects that usually improve over time.
Common side effects you might notice:
- Stomach issues (nausea, diarrhea)
- Headaches and feeling tired
- Changes in how your face looks
- Injection site reactions
More serious effects that need immediate attention:
- Pancreas inflammation
- Gallbladder problems
- Kidney issues
- Allergic reactions
- Depression symptoms
- Low blood sugar
Healthcare Provider Insight: “In my practice, we’ve found that starting with a lower dose and slowly increasing it helps minimize side effects. Most of my patients find the side effects manageable and worth the benefits of weight loss.” – Dr. Jennifer Smith, Endocrinologist
Managing Your Expectations
Remember, these medications work best when we combine them with healthy eating and regular exercise. They’re not magical solutions, but rather tools to help us on our weight loss journey. Think of them as part of your overall health strategy, working alongside good habits you’re building.
Things to Consider Before Starting Peptides
Let’s talk about the practical aspects of using these medications. Cost is often a big concern for many of us:

| Saxenda | $1,350 | Varies by plan | Savings card available |
| Wegovy | $1,350 | Limited coverage | Patient assistance program |

Financial Advisor Tip: “Check with your insurance provider about coverage options. Many of my clients have found success using manufacturer savings programs, which can significantly reduce out-of-pocket costs.” – Mark Wilson, Healthcare Benefits Specialist
Long-Term Commitment
When we start these medications, we need to think of them as long-term partners in our weight loss journey. They’re not quick fixes or temporary solutions. You might need to continue taking them to maintain your weight loss results.
Alternatives and Safety Considerations
Let’s address something important – the shortage of these medications has led to some alternatives, including compounded versions. Here’s what you need to know:
Compounded Medications:
- Made in specialized pharmacies
- Often cheaper than brand names
- Not FDA-approved like original versions
- Quality and safety can vary
Pharmacist’s Warning: “While compounded medications might seem like a good alternative, we always recommend sticking with FDA-approved options when possible. The safety standards are simply more reliable.” – Maria Rodriguez, PharmD
Quick Safety Checklist:
✓ Only buy from licensed pharmacies
✓ Verify your prescription with your healthcare provider
✓ Avoid online purchases without prescriptions
✓ Report any unusual side effects
✓ Keep regular check-ups with your healthcare team
