Hello Ameena,
Ramadan fasting with type 2 diabetes should be planned carefully. I look at glucose control, medicines, previous low or high readings, kidney and heart health, age, and other medical problems before advising whether fasting is safe.
You can use our blood sugar converter whenever you need to change mg/dL to mmol/L.
| Test | Your Result | Meaning |
|---|---|---|
| Fasting glucose | 115 mg/dL / 6.4 mmol/L | Within the usual 80–130 mg/dL / 4.4–7.2 mmol/L pre-meal target for many adults |
| Post-meal glucose | 246 mg/dL / 13.7 mmol/L | High; the usual peak post-meal target for many adults is below 180 mg/dL / 10.0 mmol/L |
| HbA1c | 8.2% | Above the common goal of below 7% |
Your fasting result is not the main concern. The higher post-meal result and HbA1c show that your glucose is rising too much during other parts of the day.
HbA1c reflects your average glucose over about two to three months. An HbA1c of 8.2% corresponds to an estimated average glucose of about 189 mg/dL (10.5 mmol/L). Your previous 6.8% was about 148 mg/dL (8.2 mmol/L), while 7.7% was about 174 mg/dL (9.7 mmol/L). This shows that your overall control has worsened again.
Possibly, but I cannot safely advise you to fast from these numbers alone. Ramadan diabetes guidance recommends an individual risk assessment before fasting. High HbA1c, kidney disease, heart disease, severe hypoglycemia, pregnancy, frailty, or other complications can increase the risk.
I recommend a diabetes review before Ramadan so your doctor can check your glucose record, HbA1c, kidney function, and medicines. Our guide to diabetes during Ramadan explains why planning and monitoring are important.
Inogla-M 500 contains teneligliptin 20 mg and metformin 500 mg. These medicines generally have a lower risk of hypoglycemia than insulin or sulfonylureas, but medication timing may still need adjustment during Ramadan.
Because you say you take half a tablet in the morning and half at night, please confirm this with your doctor or pharmacist. Inogla-M 500 contains sustained-release metformin, and sustained-release tablets should not automatically be split unless your prescriber or pharmacist confirms that your exact tablet can be divided. Do not change the dose, timing, or medicine yourself. You can learn more about diabetes medicines here.
From a medical safety standpoint, continue checking your blood glucose during the fast. Monitoring helps you recognize dangerous highs or lows before they become more serious.
You should stop fasting if your glucose becomes dangerously low or high, or if you become unwell.
| Glucose | What to Do |
|---|---|
| Below 70 mg/dL / 3.9 mmol/L | Break the fast and treat the low glucose promptly |
| Above 300 mg/dL / 16.7 mmol/L | Break the fast and follow your high-glucose plan |
Also break the fast if you develop significant dizziness, confusion, faintness, dehydration, vomiting, or severe weakness. Our page on low blood sugar explains why values below 70 mg/dL / 3.9 mmol/L need prompt treatment.
Ameena, your fasting glucose of 115 mg/dL / 6.4 mmol/L is reasonable, but your post-meal glucose of 246 mg/dL / 13.7 mmol/L is high and your HbA1c of 8.2% shows that your diabetes is not currently at the usual target.
Please arrange a pre-Ramadan consultation before deciding to fast. If your doctor considers fasting safe, you should have a clear medication schedule, glucose-monitoring plan, meal strategy, and instructions about when to break the fast.
