From Chapter 10 of The Med Spa Money Map

The GLP-1 Retention Breakdown

Left alone, a GLP-1 program loses about half its patients within a year. Ten questions score your program across the five dimensions from Chapter 10, show you the weakest one and what to do about it this week, and, if you add two numbers, estimate what the drop-off is costing you.

It scores what actually happens for your patients, not what software you use. A front desk with a good routine and a paper calendar can score at the top.

About five minutes. No email, no signup. Your answers stay in your browser.

A note on supply

How this is estimated

Chapter 10 uses two twelve-month retention curves: with nothing behind the program, about of patients are still active at month twelve (a nationwide Danish registry study of 157,822 adults starting semaglutide for weight loss found 13% had stopped by 3 months, 27% by 6, 39% by 9 and 49% by 12; JAMA Network Open, 28 Aug 2026); with onboarding and maintenance in place, about , which is a target to measure against, not a study result.

Your retention = + ( − ) × your score ÷ 30.

Patients at risk = active patients × ( − your retention): the patients a well-run program keeps that yours may not.

Revenue at risk = patients at risk × monthly price × 6 to 12 months. The low end assumes drop-off spreads across the year, so each lost patient forfeits about six months. The high end counts a full year for each. Rounded to the nearest $100.

It treats your active patients as if they started together, and it leaves out aesthetic treatments a retained patient might add later, so it's deliberately conservative. Every figure here is an estimate from your own answers, not a measurement of your practice. Your real twelve-month number is the one to trust.

All five fixes, in the book's order

Chapter 10's order: the onboarding talk first, then the timed check-ins, then a predictable price, then the aesthetic conversation.

This breakdown is about retention operations, not clinical practice. Eligibility, dosing, monitoring and sourcing are decisions for your medical team. Nothing here is medical or legal advice.

Why patients quit

Half leave within a year. Every reason they leave is fixable.

Patients rarely stop because the medication failed. When you ask the ones who stopped, the answers fall into three buckets, and a practice controls all three.

Unpredictable cost

An open-ended monthly bill gets re-decided at every refill. A set monthly program price, on a card on file or paid for a few months at once, turns that into one decision made at signup.

Unmanaged side effects

By some estimates, roughly a third of early discontinuations trace to nausea and other GI side effects, mostly in the first weeks. A check-in in the first two weeks catches a struggling patient before they quietly stop.

The conversation that never happened

Weight loss slows around month four. A patient who was told that at the first visit reads the stall as a milestone. One who wasn't reads it as the medicine giving up, and leaves.

And a patient who stops the medication doesn't have to leave the practice. Significant weight loss often brings questions about skin and facial volume, and practices that plan for that conversation, when it's clinically appropriate, keep the patient after the program ends.
