The body needs glucose for energy; it is especially critical for the brain and the rest of the central nervous system. While most cases of low blood sugar are due to the effects of medications for diabetes, some cases are unrelated. Patients experiencing non-diabetic low blood sugar, also known as hypoglycemia, usually experience symptoms and quickly eat or drink something containing carbohydrates. Uncorrected hypoglycemia can lead to coma or death.
Hunger
Fortunately, the body usually alerts us to a drop in blood sugar by causing us to feel hungry. It is common to crave something sweet, such as a milkshake or soda, which will quickly raise blood sugar.
Shakiness
A person suffering hypoglycemia may be shaky. This is often accompanied by sweating and an increase in heart rate.
Weakness
Low blood sugar may make a person feel weak and dizzy. She may feel as though she is about to pass out. It may be hard to fully rouse her, and her movements may be clumsy and uncoordinated. It is not unusual for the patient to spill her drink as she is trying to consume it.
Headache
Headache is a classic sign of dropping blood sugar. According to the Mayo Clinic, blurry vision may also be present. Some people have double vision, making eating or drinking difficult.
Confusion
The lack of glucose in the brain may quickly lead to confusion. The person may be cranky, nervous or have poor inhibition of what he says to others. His speech may be slurred; this is sometimes confused with drunkenness.
Nausea
Drugs.com describes nausea as another indicator of hypoglycemia. The person may be warm to the touch and complain of tingling skin.
How to Avoid
Recurrent hypoglycemia should be treated by a physician. To avoid symptoms, eat five small meals spread throughout the day. Eat an early breakfast and avoid skipping meals. Eat high-protein foods, and avoid concentrated sweets, such as cake with icing, pie and sugared sodas. Eat a couple of hours prior to strenuous exercise. Limit alcohol use to no more than one or two drinks per day.
