Sport and Competitive Activity
Reviewed by CDE Mehandi Sharma · Updated
Monogenic diabetes is generally compatible with sport at any level, and in the untreated subtypes it requires no special arrangements at all.
If you are not on glucose-lowering treatment — untreated GCK-MODY, for instance — there is nothing to plan around. You do not risk lows from the diabetes, and you can train and compete as anyone else would.
If you are on a sulfonylurea or insulin, the arrangements are the same as for anyone using those medicines. Check before play, carry fast-acting glucose to the field rather than leaving it in a bag indoors, and check again afterwards. For a long match or a tournament day, agree a plan for top-ups in advance.
What a coach or PE teacher needs to know is short: that you have a form of diabetes, whether you can go low, and if so what it looks like and that the answer is sugar first and questions later.
One thing worth handling deliberately: because monogenic diabetes is unfamiliar, coaches and schools sometimes apply Type 1 assumptions and become overcautious. If you are untreated, saying plainly that you do not take medication and cannot have a low usually settles it — and a note from your doctor settles it faster.
Do not accept being excluded from sport by default. That happens to people with rare diagnoses more than it should.
