If you live in Wichita and have looked into medical weight loss in the past two years, you’ve heard of semaglutide and tirzepatide. Patients ask me about them almost every week. Usually the question is simple: “Which one should I take?”
The honest answer is that it depends on you: your health history, your goals, your budget and how your body handles medication. This article walks through what I explain to patients in my Wichita clinic so you can walk into your first visit already knowing the basics.
Why this matters in Kansas
Weight is not a willpower problem here; it’s a widespread medical one. In 2025, 37.3% of Kansas adults had obesity, the eighth-highest rate in the country. Excess weight raises the risk of type 2 diabetes, high blood pressure, sleep apnea, fatty liver disease, joint pain and heart disease. For many of my patients, losing even 5% to 10% of their body weight brings real changes in blood sugar, blood pressure and energy.
What semaglutide and tirzepatide are
Both are weekly injections that copy hormones your gut releases after you eat.
- Semaglutide acts on one hormone pathway, GLP-1. It’s the active ingredient in Wegovy and Ozempic.
- Tirzepatide acts on two pathways, GLP-1 and GIP. It’s the active ingredient in Zepbound and Mounjaro.
Both medications slow how fast your stomach empties, help you feel full sooner and quiet the constant “food noise” many people describe. They also improve how your body handles blood sugar. Patients often tell me it’s the first time they’ve felt in control around food.
How much weight do people lose?
In the large clinical trials, adults on semaglutide lost about 15% of their body weight on average over roughly 16 months. Adults on tirzepatide lost about 20% on average at the highest dose over a similar period. In a head-to-head trial published in 2025, tirzepatide produced more weight loss than semaglutide on average.
Averages are not promises. Some people lose more, some lose less, and results depend heavily on nutrition, activity, sleep and sticking with the plan.
Semaglutide vs. tirzepatide at a glance
| Semaglutide | Tirzepatide | |
|---|---|---|
| How it works | GLP-1 | GLP-1 + GIP |
| How often | Once a week | Once a week |
| Average weight loss in trials | About 15% | About 20% at the top dose |
| Most common side effects | Nausea, constipation, diarrhea, reduced appetite | Similar to semaglutide |
| Open Path 8-week program | $697 | $997 |
Which one fits you?
In my practice, these are the factors that guide the choice:
- Your goal. If you have a lot of weight to lose, or you’ve plateaued on semaglutide, tirzepatide may give you more room to progress.
- Your budget. Semaglutide costs less, and many patients reach their goals on it.
- Your stomach. Both cause GI side effects. If you’ve had a hard time with one, switching to the other is sometimes better tolerated.
- Your health conditions. Prediabetes, type 2 diabetes, PCOS, fatty liver and high blood pressure all factor in, and your labs help us decide.
- Birth control. Tirzepatide can make birth control pills less effective, especially when starting and after each dose increase. If that applies to you, we’ll talk about a backup method.
Who should not take these medications
GLP-1 medications are not right for everyone. You should not take them if you:
- Have a personal or family history of medullary thyroid cancer or MEN 2 syndrome
- Are pregnant, breastfeeding or trying to conceive
- Have had pancreatitis, or have certain gallbladder or severe digestive conditions (we’ll review these with you)
This is exactly why I require a full medical evaluation and lab work before prescribing. A clinic that skips this step is skipping your safety.
Side effects and how to manage them
Most side effects are mild and fade as your body adjusts. The most common are nausea, constipation, diarrhea, bloating and tiredness in the first weeks. We start at a low dose and raise it slowly, usually every four weeks, to keep these manageable.
What helps most:
- Eat smaller meals and stop at the first sign of fullness
- Go easy on greasy, fried and very sweet foods (yes, that includes your favorite Wichita barbecue on injection day)
- Drink plenty of water, especially in a Kansas summer
- Eat protein first at every meal
Call us right away if you have severe or ongoing belly pain, vomiting you can’t stop, or signs of dehydration.
Protecting your muscle
When you lose weight quickly, some of it can come from muscle. Losing muscle slows your metabolism and makes it harder to keep weight off. That’s why every Open Path program includes strength-training recommendations, meal plans built around protein, and regular check-ins. Our 12-week Metabolic ReVIVE 360° program adds body composition scans every two weeks so we can see that you’re losing fat, not muscle.
What happens when you stop?
This is the question I wish more people asked before starting. Studies show many people regain much of their weight within a year of stopping a GLP-1 if nothing else has changed. The medication is a powerful tool, but the habits you build while on it are what keep the weight off. We plan for maintenance from the first visit, including how and when to lower your dose.
