If you need to know which are the sugar/glucose reference ranges or you require more information about the role of sugar/glucose in the blood you can visit: Normal sugar/glucose level in the blood
Hypoglycemia (low blood sugar/glucose level) usually means that the pancreas produces too much insulin.
Blood sugar values are usually given in mg/dl but sometimes you can see those values in mmol/l following the International System of Units (SI). In case your values are in mmol/l you can convert them using this tool:
Mild hypoglycemia is not usually a cause for concern but you and your doctor need to be aware and careful if there are other symptoms associated.
It often happens when you are suffering from diabetes and you are taking too much insulin.
Moderate hypoglycemia usually causes hunger, headache, sweating and weakness.
If you are not taking anti-diabetic drugs, it is recommended to visit your doctor. He should advise you what to do.
You may be hungry, sweaty and confused with blurred vision and uncoordinated movements. You can also suffer from tachycardia.
Moderate to severe traumatic brain injury can appear with prolonged low glucose levels.
Low glucose level due to an underlying disease is very common. For example, as a result of a small tumor in the pancreas called insulinoma. Therefore, you must look for medical assistance.
Severe hypoglycemia can be subsequent to or a consequence of another disease. Therefore, it is important to study your circumstances and any other information relevant for the diagnosis.
With such a low value, you can have seizures, convulsions or a loss of consciousness (coma). You need to look for urgent medical attention because you are probably unable to eat or drink.
To suffer a concreted health situation or to be taking some drugs can reduce your blood sugar/glucose level:
The following diseases can explain a blood sugar/glucose level lower than normal:
If your blood sugar/glucose level is slightly low (55 - 70 mg/dl in adults) you can add sugary food to your diet (fruit juice, sweets, grapes, raisins, pineapple, etc.)
If your sugar blood is extremely low (< 50 mg/dl in adults) you should be advised to take Glucagon to regulate the rate of glucose production and counterbalance the action of insulin.

IMPORTANT: These levels are expressed in mg/dl. They are an example of a healthy man of about 45 years of age with no known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
