Doctors suggest that a normal fasting blood sugar range is between 70–100 mg/dL (3.9–5.6 mmol/L). If your fasting blood sugar is consistently over 126 mg/dL (7 mmol/L), your doctor will diagnose diabetes. You can reduce your risk of high fasting blood sugar by eating your dinner earlier the night before.
Again, your doctor can tell you what range your blood sugar should be at different times of the day, especially before and after meals. The American Diabetes Association recommends that for most people with diabetes, a healthy blood sugar range before you eat breakfast or any other meal is between 80 and 130 mg/dL.
What should your blood sugar be when you wake up? 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 causes high morning blood glucose? Two main culprits prompt morning highs: the dawn phenomenon and waning insulin. A third, much rarer cause, known as the Somogyi effect, may also be to blame.

The best drinks for people living with diabetes
Water, unsweetened tea and coffee, sugar-free soft drinks, plain milk, fruit juices and smoothies all count towards your daily fluid requirements. We also get fluid from the food we eat, especially from fruit and vegetables.
Drinking water and staying hydrated is important for managing blood sugar, also known as blood glucose. “Water helps your kidneys filter out excess sugar through urine,” says Khan. “So, the more hydrated you are, the more urine production you'll have, which flushes out sugar in the body.”
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.
Hyperglycemia occurs when the level of blood glucose gets too high. Hyperglycemia can affect people of any age and can cause a range of symptoms, including excessive thirst, hunger, fatigue, and/or an urge to urinate larger amounts than usual.
Furthermore, in one of these recommendations, patients are advised not to squeeze the finger to obtain a drop of blood as this could potentially influence the blood glucose concentration (3).
An unhealthy blood glucose level on a fasting test is above 100 mg/dL. If you have a blood glucose level between 100 and 125 mg/dL, you may have prediabetes. If your blood glucose level is 126 mg/dL or higher, you may have diabetes. An unhealthy blood glucose level on a non-fasting test is above 140 mg/dL.
At night, symptoms of hyperglycemia include: Poor sleep. Waking up often to urinate or to drink water. Headache.
Thus, the liver makes a supply of glucose during periods of starvation (including the absence of carbs) by synthesizing it from proteins. Increased gluconeogenesis is thought to be a primary factor in type 2 diabetes and a cause of hyperglycemia (high blood sugar).
There is no specific A1C 'stroke level' but higher A1C levels are associated with an increased risk of stroke. Generally speaking, it is recommended that most people with diabetes aim for A1C levels of 7% or less .
A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours means you have diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) means you have prediabetes.
In those without diabetes, A1C levels should stay below 5.7%. Dangerous levels of A1C are 9.05% and higher. 2 An A1C above 9% increases the risk of long-term diabetes complications like blindness, nerve damage, and kidney failure. 3 Under 7% is considered good diabetes control.
The result: a quick spike in blood sugar. If you have type 2 diabetes, this means taking sugary drinks — such as regular soda, sweet tea, and even juice — off the table and replacing them with low-sugar and sugar-free options, including water.
Berries. Don't make your trip to the store fruitless. Dad jokes aside, foods like blueberries provide fiber and antioxidants known to lower blood sugar and inflammation. Similarly, one study found strawberries reduced diabetes complications like kidney disease and nerve damage.
Drinking plenty of water helps your kidneys flush out excess sugar. One study found that people who drink more water lower their risk for developing high blood sugar levels. And remember, water is the best. Sugary drinks elevate blood sugar by raising it even more.
Peanuts and peanut butter have even been shown to help lessen the spike in blood sugar when paired with high-carbohydrate or high-GL foods. Peanuts and peanut butter are both low GI and GL foods, as they contain healthy oils, protein, and fiber that have a positive effect on blood sugar control.
The preferred—and quickest—method of lowering your glucose level is to take rapid-acting insulin such as Humalog, Novolog, or Apidra.
