Fasting blood sugar (in the morning, before eating): Less than 100 mg/dL. 1-2 hours after a meal: Less than 140 mg/dL.
Whenever possible, aim to keep your glucose levels in range between 70 and 130 mg/dL in the morning before you eat breakfast, and between 70 and 180 mg/dL at other times.
What should my blood sugar level be when I wake up? These are goal levels, according to The Joslin Diabetes Center: Under 100 mg/dl if you do not have diabetes. 70 to 130 mg/dl if you have diabetes.
The expected values for normal fasting blood glucose concentration are between 70 mg/dL (3.9 mmol/L) and 100 mg/dL (5.6 mmol/L). When fasting blood glucose is between 100 to 125 mg/dL (5.6 to 6.9 mmol/L) changes in lifestyle and monitoring glycemia are recommended.
A blood sugar target is the range you try to reach as much as possible. These are typical targets: Before a meal: 80 to 130 mg/dL. Two hours after the start of a meal: Less than 180 mg/dL.
Target blood sugar levels differ for everyone, but generally speaking: if you monitor yourself at home – a normal target is 4-7mmol/l before eating and under 8.5-9mmol/l two hours after a meal.
For most people without diabetes, normal blood sugar levels are: between 4 and to 6 mmol/L before meals. less than 8 mmol/L two hours after eating.
High blood sugar levels when you wake up
If your fasting glucose before breakfast is 100–125 mg/dL (5.6–6.9 mmol/L), it's higher than doctors would expect to see in a person with healthy blood sugar control.
In general: Less than 100 mg/dL (5.6 mmol/L ) is normal. 100 to 125 mg/dL (5.6 to 6.9 mmol/L ) is diagnosed as prediabetes. 126 mg/dL (7.0 mmol/L ) or higher on two separate tests is diagnosed as diabetes.
In most cases, doctors ask people to measure fasting blood sugar immediately upon waking and before they have anything to eat or drink. It may also be appropriate to test blood sugar before eating or 2 hours after a meal, which is when blood sugar returns to normal levels.
People with diabetes should eat dinner between 8 and 9 pm. Eating close to bedtime or late at night must be avoided.
Dawn phenomenon happens when hormones your body naturally makes in the early morning (including cortisol and growth hormone) increase your blood sugar. The Somogyi effect also involves a surge of hormones, but it's due to a low blood sugar episode overnight. Dawn phenomenon doesn't happen because of low blood sugar.
Summary. Exercise in the afternoon or evening can lower morning blood sugars. If you still have a high morning reading, try exercising before breakfast. A shot of vinegar, limited evening carbs, and a low-fat dinner can help with the dawn effect.
Here are the normal blood sugar ranges for a person without diabetes according to the American Diabetes Association: Fasting blood sugar (in the morning, before eating): Less than 100 mg/dL. 1-2 hours after a meal: Less than 140 mg/dL. 2-3 hours after eating: Less than 100 mg/dL.
For the average senior, normal blood sugar levels are considered to be less than 100 mg/dL after not eating for around eight hours. After eating, they should be less than 140 mg/dL.
The dawn phenomenon is an early-morning rise in blood sugar, also called blood glucose, in people with diabetes. The dawn phenomenon leads to high levels of blood sugar, a condition called hyperglycemia. It usually happens between 4 a.m. and 8 a.m.
If your fasting blood glucose level is between 3.6mmol/l and 6mmol/l, this means that your blood glucose level is normal. If your fasting blood glucose level is 7mmol/l or higher, this is likely to mean that you have diabetes.
What is a normal blood glucose level? For a person without diabetes, throughout the day blood glucose levels (BGLs) will generally range between 4.0 – 7.8 millimoles of glucose per litre of blood (mmols/L) regardless of how they eat or exercise, or what stress they're under.
A normal pre-prandial (before meal) blood glucose level will be between 4 and 7 mmol/l. Aftereating (post-prandial) levels should be below 9 mmol/l when tested 2 hours after a meal. When going to bed for the night, levels should be no more than 8 mmol/l.
Fasting test results
Normal: 3.9 to 5.4 mmols/l (70 to 99 mg/dl) Prediabetes or Impaired Glucose Tolerance: 5.5 to 6.9 mmol/l (100 to 125 mg/dl) Diagnosis of diabetes: 7.0 mmol/l (126 mg/dl) or above.
If your A1C level is between 5.7 and less than 6.5%, your levels have been in the prediabetes range. If you have an A1C level of 6.5% or higher, your levels were in the diabetes range.
If your diabetes remains hard to manage even after you begin taking metformin, or you cannot tolerate metformin or do not want to take it, that's when a GLP-1RA or SGLT2i might come in. Studies have shown that both medications are safe and effective at lowering blood glucose when compared to a placebo.
Mild high blood sugar
If your blood sugar levels are consistently higher than your target range (usually 11 mmol/L to 20 mmol/L, and 11 mmol/L to 14 mmol/L in children), you may have mild symptoms of high blood sugar.
