# Why Isn't Obesity in Your Medical Record? One in Ten Had It Written Down Why isn't obesity in your medical record? Among 42,243 adults with BMI 30 or more, 10.6% had it documented at discharge vs 59.7% for diabetes | four studies.

One in Ten Had It Written Down 42,243 hospitalized adults all had a BMI of 30 or more on the chart. It reached the discharge summary for 10.6% of them, against 59.7% for diabetes.

Because a measured weight and a written diagnosis are two different events, and the second one is skipped far more often than the first. In a decade of hospital records covering 42,243 adults whose BMI of 30 or more was already on the chart, only 10.6% left with obesity documented in the discharge summary [\[1\]](https://thisglp.com/research/why-isnt-obesity-in-your-medical-record#ref-1). Diabetes, by contrast, was written down for 59.7% of the patients whose HbA1c met its criterion, and that difference matters to anyone hoping to be treated. ## Key takeaways - 42,243 hospitalized adults with a BMI of 30 or more: obesity documented at discharge for 10.6%. - Diabetes was documented for 59.7% of those with HbA1c at or above 6.5%, and severe dyslipidemia for 39.0%. - Documented patients had 3.44 times the odds of a GLP-1 prescription, an association rather than a proven cause. - In one primary care practice, obesity was documented for 27.5% of patients who had it, against 83.3% for hypertension. - A standard electronic template raised documentation in young children from 34% to 47%. ## What the hospital study found Everyone in the study was admitted between 2013 and 2023 with a BMI of 30 or above and no earlier obesity code [\[1\]](https://thisglp.com/research/why-isnt-obesity-in-your-medical-record#ref-1). Every one of them had been weighed and measured before a doctor wrote a word. Their mean BMI was 33.9 and their mean age 60.9, and nine in ten of them went home with a discharge summary that never named the condition the scale had recorded. The comparison with the laboratory conditions is what makes the gap hard to explain away. Diabetes needs a blood sample and a result coming back, and it reached the summary for 59.7% of patients whose HbA1c was 6.5% or higher; severe dyslipidemia, with an LDL-C of 190 or more, reached it for 39.0%. Each additional BMI unit raised the odds of coding by 17%, so the higher the number, the likelier someone was to write it down. That is a gradient of judgment rather than a line at 30, much as [the BMI cut-off for these drugs](https://thisglp.com/research/what-bmi-do-you-need-for-a-glp1) is a convention rather than a boundary in the body. ## The same gap in a primary care office An older, smaller study went through a year of records from one community practice, where 22 physicians between them cared for more than 13,000 patients with obesity [\[2\]](https://thisglp.com/research/why-isnt-obesity-in-your-medical-record#ref-2). Obesity made it into the record for 27.5% of those patients, while hypertension in the same charts was documented 83.3% of the time. The authors also sorted the physicians by their own BMI, and the pattern was not a tidy one: 23.2% for the six normal-weight doctors, 33.5% for the ten who were overweight, and 21.7% for the six with obesity themselves. It is one practice, and the sample of doctors is small enough that no single number in it should be carried very far, but the headline gap against hypertension is the same shape as the hospital finding. Measured is not the same as written down A third study looked a step earlier, at whether the measurement itself reaches the chart. In the records of 707,819 Canadian adults aged 40 and over, 48.7% had at least one BMI recorded and 11.5% had a waist measurement [\[4\]](https://thisglp.com/research/why-isnt-obesity-in-your-medical-record#ref-4). So in routine primary care the number that a diagnosis would rest on is missing for about half of patients before the diagnosis question even comes up. ## What helped, where anything did The one intervention in this set was modest and practical. At a pediatric primary care clinic, researchers followed 585 children under six with a BMI above the 99th percentile and compared well-child visits that used a standardized electronic template with visits that did not [\[3\]](https://thisglp.com/research/why-isnt-obesity-in-your-medical-record#ref-3). Documentation of obesity rose from 34% to 47% with the template, and with obesity in the chart, nutrition counseling rose from 44% to 66% and physical activity counseling from 9% to 23%. Young children are a separate question for treatment, covered in [the guide to teenagers](https://thisglp.com/research/are-glp1-drugs-safe-for-teens), but the lesson about templates travels. ## Why it matters if you want treatment In the hospital study, patients whose obesity was coded had 2.26 times the odds of a metabolic clinic visit and 3.51 times the odds of bariatric surgery. Their odds of a GLP-1 prescription were 3.44 times higher, with a 95% CI of 2.76 to 4.28 [\[1\]](https://thisglp.com/research/why-isnt-obesity-in-your-medical-record#ref-1). That is an association, and the arrow can run either way, since a doctor who has already decided to treat has a reason to write the diagnosis, but it shows how closely the paperwork and the prescription travel together. The practical version is short. If your weight has been measured and never discussed, it is reasonable to ask at the next visit whether obesity is on your problem list. You would expect a high blood pressure reading to end up there too. Whether a condition is on record also shapes who counts as eligible for the narrower approvals, like [semaglutide for liver disease](https://thisglp.com/research/who-qualifies-for-semaglutide-for-liver-disease), and what good care around these drugs should include is set out in [what a GLP-1 provider should do](https://thisglp.com/research/what-should-a-glp1-provider-actually-do). What none of these studies answers is whether writing the diagnosis down, on its own, changes what happens to a patient afterwards, and that is the question a trial would have to settle. The hospital authors’ own conclusion is narrower and fair: closing the documentation gap is a prerequisite for turning a measured BMI into care. ## Frequently asked Why isn't obesity listed as a diagnosis in my chart? Measuring a BMI and writing obesity down as a diagnosis are separate steps, and the second is often skipped. In 42,243 hospitalized adults with a BMI of 30 or more, only 10.6% had obesity documented at discharge. How often do doctors document obesity compared with other conditions? In the hospital study, 10.6% for obesity against 59.7% for diabetes and 39.0% for severe dyslipidemia. In one primary care practice, 27.5% for obesity against 83.3% for hypertension. Does having obesity documented make a GLP-1 prescription more likely? Documented patients had 3.44 times the odds of a GLP-1 prescription. That is an association: a clinician who already plans to treat also has a reason to write the diagnosis. Can I ask my doctor to add obesity to my problem list? Yes. If your BMI has been measured, it is reasonable to ask whether obesity is recorded, just as you would for a high blood pressure reading. ## Sources 1. \[1\] Avivi I, Zelmanoff DD, Golan N, Arbel Y (2026).
