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.
Dangerous levels of A1C are 9% and higher. An A1C above 9% increases the risk of long-term diabetes complications like blindness, nerve damage, and kidney failure. 1 Under 7% is considered good diabetes control. In non-diabetics, A1C levels stay below 5.7%.
Optimal control, minimal risk of complication, glucose levels up to 3.5 -7.4 mmol/L. Sub-optimal control, moderate risk of complication, glucose levels are 7.4-9.1 mmol/L. Inadequate control, excessive risk of complication, glucose levels are over 9.1 mmol/L.
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. For most people without diabetes, normal blood sugar levels are: between 4 and to 6 mmol/L before meals.
As a result, levels of glucose in the blood stream can reach high levels, causing hyperglycemia or high blood sugar. Hyperglycemia occurs when the blood sugar is above 130 mg/dL while fasting, or greater than 180 mg/dL after eating a meal.
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.
When people with diabetes have an A1c level above 9 percent, they may need more care and treatment. Clinical trials have shown that having A1c levels above 9 percent increases the risk of complications.
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.
Less than 100 mg/dL (5.6 mmol/L ) is considered healthy. 100 to 125 mg/dL (5.6 to 6.9 mmol/L ) is diagnosed as prediabetes. 126 mg/dL (7 mmol/L ) or higher on two separate tests is diagnosed as diabetes.
High blood sugar (hyperglycemia) occurs when your blood sugar is at or above 11 mmol/L.
In general: Less than 140 mg/dL (7.8 mmol/L ) is normal. 140 to 199 mg/dL (7.8 to 11.0 mmol/L ) is consistent with prediabetes. 200 mg/dL (11.1 mmol/L ) or higher after two hours suggests diabetes.
Blood sugars below 50 mg/dL or above 250 mg/dL are alarming. You should seek immediate medical attention if these blood glucose levels persist despite treatment at home.
A reading above 300 mg/dL can be dangerous, according to the University of Michigan, which recommends immediately informing your doctor if you have two or more readings of 300 mg/dL in a row. In severe cases, very high blood sugar levels (well above 300 mg/dL) can result in coma.
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.
Adults over the age of 60 should try to maintain glucose levels between 100 to 140 mg/dL. Below are some of the issues associated with high glucose levels and what your aging loved one can do to maintain healthy blood sugar.
From 90 to 130 mg/dL (5.0 to 7.2 mmol/L) for adults. From 90 to 130 mg/dL (5.0 to 7.2 mmol/L) for children, 13 to 19 years old. From 90 to 180 mg/dL (5.0 to 10.0 mmol/L) for children, 6 to 12 years old. From 100 to 180 mg/dL (5.5 to 10.0 mmol/L) for children under 6 years old.
Laboratory Assessment
Using commercial assays, normal fasting insulin levels range between 5 and 15 μU/mL but with more sensitive assays normal fasting insulin should be lower than 12 μU/mL .
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.
Testing too soon after you've had a meal or a snack will give you results that are probably too high. The solution for better diabetes control: Test fasting blood sugar, and test every time before you eat. Wait two hours after eating to get the best reading.
