Is blood sugar level of 107 or 110 mg/dL high?

by Roni
(US)

Question from Roni:

My blood sugar sometimes goes up to 107 or 110 mg/dL. My doctor said I do not have to worry, but I am not sure if this number is high or normal.

Is 107 a good blood sugar level? What about 110 mg/dL?

Quick Answer

A blood sugar level of 107 or 110 mg/dL can be normal or slightly high depending on when it was checked.

If it was checked after eating, it is usually a good reading. If it was checked after at least 8 hours of fasting, it is slightly above normal and falls in the prediabetes range.

One reading alone does not diagnose diabetes. If fasting readings stay between 100–125 mg/dL, ask your doctor about repeating the test and checking HbA1c.

Answer by Dr. Albana Greca, MD, MMedSc

Hi Roni,

I understand your concern. A glucose reading of 107 or 110 mg/dL is not usually dangerous, but the meaning depends on whether it was a fasting, random, or after-meal reading.

Is 107 or 110 mg/dL High?

Fasting Blood Sugar	Meaning
Less than 100 mg/dL	Usually normal
100–125 mg/dL	Prediabetes range
126 mg/dL or higher	Diabetes range if confirmed

So, if your 107 or 110 mg/dL result was a true fasting blood sugar, it is mildly above the normal fasting range. It is not diabetes, but it is a useful early warning sign.

If the same number was taken after eating, it is usually a good result because after-meal blood sugar commonly rises higher than fasting blood sugar.

Why Can Blood Sugar Be Slightly High?

Not fasting long enough before the test

A late or high-carbohydrate dinner the night before

Poor sleep, stress, illness, or infection

Less physical activity than usual

Insulin resistance or early prediabetes

Medicines such as steroid tablets or injections

What Should You Do Next?

Since your doctor said not to worry, that is reassuring. Still, if these numbers are fasting readings and they happen repeatedly, ask about:

Repeating the fasting blood sugar test

Checking an HbA1c test

Reviewing weight, waist size, blood pressure, cholesterol, and family history

Improving food choices, activity, sleep, and stress habits

Can Lifestyle Changes Help?

Yes. If fasting blood sugar is slightly high, lifestyle changes can often improve insulin sensitivity and reduce the risk of type 2 diabetes.

Choose more vegetables, beans, lentils, nuts, and high-fiber foods

Reduce sugary drinks, sweets, and refined white flour foods

Walk after meals when possible

Aim for regular physical activity

Follow up with your doctor if readings stay high

Important Safety Note

A fasting blood sugar of 107 or 110 mg/dL is not usually an emergency. Contact your doctor if you have repeated high readings, increased thirst, frequent urination, unexplained weight loss, blurred vision, fatigue, or a strong family history of diabetes.

Doctor’s Note

Roni, do not panic about a single 107 or 110 mg/dL reading. If it is fasting and repeated, treat it as a signal to confirm your results and strengthen lifestyle habits early.

Most Asked Questions

Is blood sugar 107 mg/dL bad?

Not necessarily. If it was after eating, it is usually fine. If it was fasting, it is slightly above normal.

Is blood sugar 110 mg/dL diabetes?

No. A fasting blood sugar of 110 mg/dL is in the prediabetes range, not the diabetes range.

Should I check HbA1c?

Yes, if fasting readings are repeatedly 100–125 mg/dL, HbA1c can help show your average blood sugar over 2–3 months.

Blood sugar 154 when woke up; blood pressure 140 over 95
by: Anonymous

QUESTION: Hello,

I was wondering my blood sugar was at 154 when I woke up I'm breast feeding as well is that normal or bad.

Also my blood pressure is at 140 over 95 is that good as well or bad .

My husband lately his heart rate on the blood pressure monitor said it was 117 heart rate and 122 another time is that normal?

ANSWER: Hello,

If the blood sugar levels you checked when you woke up,then, I advise to recheck them again:
- fasting, make sure you do not eat or drink anything from the night before until morning except for plain water.
- get a sugary drink, then, check again after 2 hours. If still high, should check HbA1C level.
- Blood pressure is high perhaps due to coffee intake, or stress. Should monitor blood pressure for 1 week, record the results for reference.
Can send to me the results to analyze them.

- With regards to your husband's increased heart rate, it could be due to caffeinated drinks or energetic drinks he might be using.
I advise to consult further with cardiologist, and run a complete cardiac check up to rule out cardiovascular problems.

Hope this answers to your queries.
Let me know if you have any other concern. Do not forget to send the reports to me soon.

Fasting blood sugar 112 but urinate often why?
by: Anonymous

QUESTION: Hello Doctor

My fasting blood sugar is 112 but I urinate often.. What is it and how do I be free from it please I need a clear answer please

ANSWER: Hello,

I understand your concern. Urinating often is linked to diabetes, but not only. There are other factors that are also causing frequent urination.

The most common causes are infections of urinary tract, consumption of caffeinated drinks/alcohol; stress.

I advise to get a home testing of urine to rule out infection first.

Avoid drinking fluids after 6 p.m.

Avoid excessive consumption of caffeinated drinks, try to cope with stress.

Hope this helps.

ANSWER: Hello,

Your case seems to be related to nocturnal hypoglycemia as you've been eating low glycemic fruits/foods.

Better to check HbA1C level, and rule out anemia first.

Try to have your meals regularly during all daytime.

Let me know your HbA1C result.

All the best.

Hi,

Thank you for posting.

Your blood sugar level (bsl) of 107 mg/dl falls within normal range.

Take note that the upper limit for blood sugar is:
- fasting: 110
- two hours after eating: less than 180

So, yours (107) is within normal range in either cases.

If your doctor said nothing over 100, I advise to sit down with your doctor and discuss further about your blood sugar numbers.

Individual ranges are highly recommended depending on the personal health situation of the patient and personal/family history.

If you are having any symptom with the current blood sugar levels, please let me know. Perhaps we are missing something here and should go for further evaluations.

Hope this answers your query!
