📉 Avoiding Compression Lows — Diabetic Daddy

Is your CGM telling you you're low — but you're not sure it's real?

Important: A suspected compression low should never simply be ignored. If a CGM reading is unexpectedly low, particularly if you have symptoms of hypoglycaemia, follow your usual hypo treatment plan and/or confirm the glucose level with a blood glucose meter where appropriate. Always follow the advice of your diabetes healthcare team.
