T1D is one of the fastest-growing chronic health conditions in the world. See the numbers.
How many days have you lived with T1D? How many hours of sleep have you likely lost? Use our calculator to do the math, then share your numbers!
Living with T1D and the challenges it brings is largely unknown to most people whose lives are untouched by the disease.
Numbers don’t lie and are a great way to quickly tell your story!
Use our calculator and we will send you a sharable, illustrated data snapshot showing how daily life with T1D affects you and your family.
Answer a few short questions to reveal your numbers. When a question has an asterisk*, an answer is required.
These figures are based on published averages and are an estimate, not a medical record.
Adding up your numbers…
Every number here is a snapshot of the effort T1D takes — and a reason we keep pushing for cures.

Are you wondering how we got your numbers? Here's how we did it.
When you entered your date of diagnosis, we calculated the number of days you've lived with T1D.
If you picked finger prick test, we calculated that you would do approximately eight* a day after 1980 and 0 before.
If you picked continuous glucose monitor (CGM), we calculated that you would do approximately eight finger prick tests a day until the date you started on your CGM and approximately one** test a day since.
If you picked the flash glucose monitor, we calculated that you would do approximately eight finger prick tests a day until the date you started on your flash and approximately one** test a day since then.
We calculated that you would have done approximately one* injection a day before 1980, two** injections a day between 1980 and 1990, and seven*** injections a day from 1990 until today.
We calculated that you would lose approximately four hours of sleep a week due to T1D.
We calculated that you would spend approximately 2 hours a week recovering from a hypo.

The calculator adds up how many insulin injections you’ve likely had, how many hours of sleep you’ve likely lost because of T1D, how many blood glucose checks you’ve likely done and more—going all the way back to your date of diagnosis!
Your numbers, based on averages, show the approximate impact of the time and effort you spend managing your diabetes and will help show the world how resilient and strong people with T1D are.
The averages of your numbers will help us advocate for all people impacted by T1D and raise awareness about what it’s like to live with the disease.
