Tirzepatide · GLP-1 medication
Tirzepatide: Two fullness signals working together, and habits built to last.
Tirzepatide works on two of the body's own fullness hormones, not one. At Integrated Functional Health it is never the whole plan. It is a tool that can make eating less feel natural again, paired with coaching that helps your progress last after the medication ends.

Tirzepatide in brief
Tirzepatide is a long lasting version of two fullness hormones your gut already makes, GIP and GLP-1. It quiets hunger and "food noise" in the brain, keeps meals with you for longer, and helps your body handle blood sugar after eating. Smaller, satisfying portions start to feel natural rather than forced.
- What it is: A dual GIP and GLP-1 medication working with natural appetite signals.
- How it is taken: A small injection under the skin, once a week.
- Often explored for: Weight loss, appetite control and steadier blood sugar.
- Dose: Started low and raised gradually by your provider.
- Status: Active ingredient of FDA approved medicines; compounded versions are not FDA approved.
What it is
What is Tirzepatide?
Tirzepatide is the first of a newer kind of medication that acts on two gut hormones at once: GIP and GLP-1. Both are signals your own body releases after you eat. Together they tell your brain you have had enough and help your body handle the sugar from your meal. Tirzepatide is a long lasting version of both signals in one molecule, so one weekly dose keeps it working all week.
It is the active ingredient in FDA approved medications for chronic weight management and for type 2 diabetes. When an independent licensed provider decides it is right for you, they also decide whether an FDA approved product or a medication compounded by a licensed pharmacy for you individually is the better fit.
How it works
How Tirzepatide works
Tirzepatide works in your brain and your digestive system, through two hormone pathways rather than one.
The GLP-1 part acts on the areas of the brain that regulate hunger and reward. Many people describe quieter "food noise": fewer intrusive thoughts about food, less pull toward snacks, and an easier time stopping when they are satisfied. In the gut, it slows how quickly the stomach empties, so meals keep you full for longer.
The GIP part is thought to add to that effect on appetite and to improve how the body responds to insulin and handles fat after meals. Both hormones help the pancreas release insulin when blood sugar rises, and only then, which supports steadier energy through the day. Researchers believe the pairing of the two signals helps explain the size of the results seen in trials. The medication turns down the volume; coaching changes the patterns underneath.

How it is used
What taking Tirzepatide looks like
Your independent licensed provider sets your dose and adjusts it over time. Here is what the routine involves.
- Form: A small injection under the skin of the abdomen, thigh or upper arm, with a very fine needle.
- How often: Once a week, on the same day each week. Rotate the spot each time.
- Dose: Your provider starts with a low dose and increases it gradually, which helps your body adjust.
- Lower dose options: Some people are prescribed a smaller, gentler dose. Your provider decides what suits you.
- How long: Many people use it for several months or longer, with regular check ins.
- Storage: Keep it in the refrigerator unless your pharmacy tells you otherwise.
What the research says
The evidence, plainly
Tirzepatide has been studied in large clinical trials. In the SURMOUNT-1 trial of the FDA approved medication (New England Journal of Medicine, 2022), adults with obesity who also received lifestyle support lost an average of about 21 percent of their body weight over 72 weeks on the highest dose, compared with about 3 percent on placebo. The SURPASS trials found meaningful improvements in blood sugar and weight in adults with type 2 diabetes.
The research also shows what the medication does not do on its own. In the SURMOUNT-4 trial, people who switched to placebo after several months of treatment regained a substantial part of the weight they had lost, while those who continued kept losing. Part of the weight lost can also be muscle. Both findings point to the same thing: the habits you build while taking it decide what you keep.
Safety
Who it suits, and what to watch for
It may not be right for
- Anyone who is pregnant, planning a pregnancy or breastfeeding
- A personal or family history of medullary thyroid cancer, or MEN 2 syndrome
- A history of pancreatitis, gallbladder disease or recent gallbladder removal
- A current or past eating disorder, such as anorexia or bulimia
- Type 1 diabetes, insulin, sulfonylureas or another GLP-1 medication for diabetes
- Diabetic retinopathy, which is eye damage caused by diabetes
- Bariatric surgery in the past 12 months
- Very high triglycerides, warfarin use, or cocaine or methamphetamine use
- People already at a lower body weight, for whom standard dosing is not used
Your provider reviews your full health history and current medications before prescribing.
Possible side effects
- Nausea, especially in the first weeks or after a dose increase
- Diarrhea, constipation or an upset stomach
- Feeling full quickly, reduced appetite or occasional vomiting
- Tiredness, heartburn or headache as your body adjusts
- Mild redness or itching at the injection site
- Rare but serious: pancreatitis, gallbladder problems or dehydration affecting the kidneys
In animal studies, tirzepatide caused thyroid C-cell tumors; it is not known whether this happens in people. If a side effect is severe or does not settle, contact your provider. For severe stomach pain, a lump in the neck, trouble swallowing or signs of an allergic reaction, call 911.
How it fits your plan
More than a prescription
Tirzepatide can quiet the noise. It cannot teach your brain a new relationship with food, protect your muscle, or keep the weight off once it stops. That is the work we do with you. Our weight loss coaching and the online X360 Weight Loss program focus on the patterns behind eating: stress, habit, emotion and the nervous system. Regulate, Integrate, Optimize is the thread: settle the stress response, help the brain work with you rather than against you, and build habits for the long run.
Alongside the medication we focus on protein at every meal, resistance training to protect muscle, hydration, sleep and daily steps. If you choose, lab work at a local Labcorp or Quest location and professional grade supplements can round out the plan. The goal is not only a smaller number on the scale. It is a body and a brain that keep the result.
Good to know
The details that matter
- Tirzepatide is the active ingredient in FDA approved medicines. Compounded tirzepatide is not FDA approved and has not been reviewed by the FDA for safety, effectiveness or quality.
- It is prescribed only after an independent licensed medical provider reviews your health history and decides it is appropriate. Your provider also sets your dose.
- Your medication is prepared by an independent licensed pharmacy and shipped to your door, in most states.
- If you take birth control pills, ask your provider about a backup method, since tirzepatide can make oral contraceptives less reliable.

Questions
Questions about Tirzepatide
How quickly will I notice a difference?
Many people notice quieter hunger within the first few weeks. Weight change is usually gradual, because the dose is raised slowly to help your body adjust. Steady progress over months is the pattern the research describes, and it is the pattern most likely to last.
Will I have to take it forever?
Not necessarily. Some people use it for a defined period while they build new habits; others continue longer under their provider's care. The SURMOUNT-4 trial showed that stopping without strong habits often means regaining weight, which is why coaching starts on day one rather than at the end.
How do I protect my muscle while losing weight?
Eat protein at every meal, lift or do some form of resistance training two to three times a week, and keep moving every day. These are built into our coaching and the X360 Weight Loss program, because the goal is to lose fat while keeping the muscle that powers your metabolism.
What is the difference between tirzepatide and semaglutide?
Both are weekly medications that work on appetite and blood sugar. Semaglutide acts on one hormone pathway, GLP-1. Tirzepatide acts on two, GIP and GLP-1. Your provider will talk with you about which is the better fit for your health and goals.
How do I get started?
Book a 30 minute consultation with Matt DeWild, RN, at the clinic or by telehealth. You will talk about your goals and your history, and Matt will explain how the medical assessment with an independent licensed provider works. There is no obligation.
