It looks like you shared a sentence—would you like me to revise it, expand it, or use it in a larger piece of writing?
Here are a couple of polished alternatives in case that’s what you need:
Clear and concise:
“Many people with abnormal blood sugar levels don’t recognize the early warning signs their bodies give them.”
More formal:
“A significant number of individuals with dysregulated blood sugar fail to notice the warning signals their bodies attempt to convey.”
If you’d like it rewritten for a specific tone, audience, or format, just let me know!
