Michael Patrick Buonocore (USA) (b. 19 May 2001), survived a blood sugar level of 147.6 mmol/L (2,656 mg/dl) when admitted to the Pocono Emergency Room in East Stroudsburg, Pennsylvania, USA, on 23 March 2008. The normal blood sugar range is between 4.4 to 6.6 mmol/L (80-120 mg/dl).
What is the highest blood sugar level that is safe? For a diabetic individual blood sugar levels between 160 to 240mg/dl is highest sugar levels that is safe. Normal blood sugar level for any individual before meals is between 80 to130 mg/dL. After 1-2 hours of meal it should be less than 180 mg/dL.
If your blood sugar level is slightly high for a short time, emergency treatment won't be necessary. But if it continues to rise you may need to act fast to avoid developing diabetic ketoacidosis (DKA). If your blood sugar level is 15 mmol/l or more, you should check your blood or urine for ketones.
If your blood sugar levels are consistently high (usually above 20 mmol/L in adults and above 14 mmol/L in children), you may have moderate to severe symptoms of high blood sugar.
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. if you're tested every few months – a normal target is below 48mmol/mol (or 6.5% on the older measurement scale)
Before meals, the suggested target blood glucose range is 4.0 to 8.0 mmol/L. At 2 hours after meals, the range is 5.0 to 10.0 mmol/L.
What do my blood sugar numbers mean? Persistently high blood sugar usually means you have diabetes. If HbA1c is more than 48 mmol/mol or fasting blood glucose is more than 11 mmol/L, your blood sugar is high.
A blood sugar level below 70 mg/dL (3.9 mmol/L) is low and can harm you. A blood sugar level below 54 mg/dL (3.0 mmol/L) is a cause for immediate action. You are at risk for low blood sugar if you have diabetes and are taking any of the following diabetes medicines: Insulin.
People with diabetes are at heightened risk of falling into a diabetic coma from high blood sugar once their blood sugar levels reach 600 mg/dL or higher.
A blood glucose level above 15mmol/L is considered hyperglycaemia.
NICE guidelines for the UK currently recommend the following: 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.
Results are interpreted as follows: Less than 140 mg/dL (7.8 mmol/L ) after two hours is considered healthy. 140 to 199 mg/dL (7.8 mmol/L and 11.0 mmol/L ) is diagnosed as prediabetes. 200 mg/dL (11.1 mmol/L ) or higher after two hours suggests diabetes.
If hypoglycemia becomes severe, you may not be able to safely swallow food or drink. By this point, your blood glucose level is less than 54 mg/dL—often below 40 mg/dL. You may feel very confused, pass out, or have a seizure. Without prompt treatment, severe hypoglycemia may lead to a coma or even death.
Diagnosis. Blood sugar levels that occur during a diabetic coma include: Blood sugar that is higher than 300 mg/dL two times in a row for no reason. Blood sugar that is low, less than 70 mg/dL, and the numbers don't increase after three treatments.
Causes of Low Blood Sugar
Taking too much insulin. Not eating enough carbs for how much insulin you take. Timing of when you take your insulin. The amount and timing of physical activity.
Hyperglycemia, the term for expressing high blood sugar, has been defined by the World Health Organisation as: Blood glucose levels greater than 7.0 mmol/L (126 mg/dl) when fasting. Blood glucose levels greater than 11.0 mmol/L (200 mg/dl) 2 hours after meals.
Since your body doesn't respond to insulin the same as most, your fasting blood sugar reading can go up, even if you follow a strict diet. The boost in sugar is your body's way of making sure you have enough energy to get up and start the day.
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. The cause of the dawn phenomenon isn't clear. Some researchers believe the overnight release of certain hormones that happens naturally increases insulin resistance.
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.
