Low blood sugar is called hypoglycemia. 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.

A simple blood test can tell you what your blood sugar level is. This is usually measured after fasting for 8 hours (no food, and only water to drink). is 70 to 89 mg/dl, according to the American Diabetes Association. If your blood sugar level is in the “high normal” range, you are still at risk for type 2 diabetes.

A normal fasting blood glucose level is lower than 95 mg/dL (5.3 mmol/L). One hour after drinking the glucose solution, a normal blood glucose level is lower than 180 mg/dL (10 mmol/L). Two hours after drinking the glucose solution, a normal blood glucose level is lower than 155 mg/dL (8.6 mmol/L).

For a person without any type of diabetes, blood sugar levels are generally between 70 to 130 mg/dL depending on the time of day and the last time they ate a meal. Newer theories about non-diabetic blood sugar levels have included post-meal blood sugar levels as high as 140 mg/dL.

Within two hours after eating, blood sugar levels should drop to under 140. After several hours without eating, blood sugar can drop as low as 70.

In South Africa, blood glucose levels are measured in millimoles per litre. Good management entails regular blood glucose monitoring – i.e. testing your blood glucose levels and adjusting your treatment accordingly. The normal range in people who do not have diabetes is considered to be between 4 and 6 mmol/l.

will typically lower blood glucose levels, with the effects lasting for several hours. Normal fasting glucose levels are typically 70-109 mg/dl. has defined impaired fasting glucose as 100-125, a range not yet adopted by all.

Hypoglycemia is the medical term for low blood sugar (low blood glucose). Your body, especially your brain, depends on this sugar to work. Too little sugar in your blood causes problems that can sometimes be serious. Hypoglycemia is common in people with type 1 diabetes (T1D).

A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 7.0 mmol/L) is considered prediabetes. This result is sometimes called impaired fasting glucose. A fasting blood sugar level of 126 mg/dL (7.0 mmol/L) or higher indicates type 2 diabetes.
236753
A blood sugar level less than 140 mg/dL (7.8 mmol/L) is considered normal. A blood sugar level from 140 to 199 mg/dL (7.8 to 11.0 mmol/L) is considered prediabetes. This is sometimes referred to as impaired glucose tolerance.

Target ranges may differ depending on your age, duration of diabetes, the type of medication you are taking and if you have any other medical problems. Speak with your doctor about your individual target ranges. Normal blood glucose levels are between 4.0–7.8mmol/L.

Most people will feel the effects and symptoms of low blood sugar when blood glucose levels are lower than 50 mg/dL. Symptoms and signs include nervousness, dizziness, trembling, sweating, hunger, weakness, and palpitations. Severe cases may lead to seizures and loss of consciousness.

Such high levels tend to be uncommon in type 2 diabetes, though. Blood sugar concentrations below 3.3 mmol/L (60 mg/dL) are considered to be too low. As you can see in the illustration below, there are no clear-cut borders between the normal range of blood sugar and high and low blood sugar.

According to the American Diabetes Association, normal blood sugar levels for a person of any age include: Fasting blood sugar (in the morning, before eating): under 100 mg/dL. 1 hour after a meal: 90 to 130 mg/dL. 2 hours after a meal: 90 to 110 mg/dL.

Hypoglycemia. Documented low-glucose events (symptomatic and asymptomatic) <70 mg/dL (3.9 mmol/L), 60 mg/dL (3.3 mmol/L), and 50 mg/dL (2.8 mmol/L) were counted from SMBG values by an algorithm encoded in Microsoft Excel (version 2010; Microsoft, Redmond, WA).

Hypoglycemia refers to dangerously low blood glucose levels that drop below 70 mg/dL. Significant hypoglycemia is considered below 54 mg/dL. It is an acute complication of diabetes and occurs in individuals who use insulin or specific kinds of oral diabetes medication.

Hypoglycemia needs immediate treatment when blood sugar levels are low. For many people, a fasting blood sugar of 70 milligrams per deciliter (mg/dL), or 3.9 millimoles per liter (mmol/L), or below should serve as an alert for hypoglycemia.
