Wrong timing can send your sugar crashingโฆ or silently rising all day.
Every Ramadhan, this happens.
We plan our meals carefully.
We plan our prayer times carefully.
But insulin?
โMaybe I just reduce on my own or skip it altogether. Iโm fasting, so my sugar will be low anyway.โ

Even when you are not eating, your liver still releases glucose.
Without enough insulin, blood sugar can climb quietly for hours.

A patient stopped daytime insulin during fasting.
By late afternoon he felt exhausted and nauseated, assuming it was just normal fasting fatigue.
His glucose was dangerously high.
Fasting did not cause it. Unadjusted or skipped insulin did.

Normal insulin dose at iftar.
Large meal. Sweet drinks. Several kuih.
Sugar spikes overnight.
Next day, long-acting insulin was never adjusted, blood sugar drops too low before iftar.

Severe hypoglycaemia can cause confusion, seizures, collapse and coma.
Severe hyperglycaemia can cause dehydration, hospitalisation, even life-threatening emergencies.

1. Pre-Ramadan medical review: changes in diet and insulin regimen may need to be made.
2. Do not stop insulin without medical advice.
3. Self monitor blood glucose more frequently: pre-sahur, 2 hours post-sahur, midday, pre-iftar, and 2 hours post iftar.
4. Break the fast immediately if:
โข Blood glucose < 3.3 mmol/L at ANY time during fasting.
โข Blood glucose < 3.9 mmol/L in the early hours of fasting (especially within the first few hours after sahur, as levels may continue dropping).
โข Blood glucose > 16.7 mmol/L at any time.
โข You have symptoms of hypoglycaemia, hyperglycaemia, dehydration, or feel unwell.
5. Appropriate meal planning.
Breaking the fast for medical safety is permitted. Preserving life takes priority.
Ramadhan is about discipline. Proper insulin adjustment is part of that discipline.
๐๐ถ๐ป๐ฎ๐น ๐๐ต๐ผ๐๐ด๐ต๐:
Fasting is an act of faith. Managing your insulin is an act of responsibility.
Please share this with that friend who plans their kuih carefullyโฆ but adjusts insulin based on guesswork.
