Full Answer

A person with low blood sugar may suffer from symptoms such as blurred vision, fatigue, mood changes, sweating and difficulty sleeping, notes Healthline. In more extreme cases, low blood sugar may cause seizures and nervous system damage. Hypoglycemic unawareness is a condition in which sufferers do not recognize when their blood sugar levels are dropping, and they may experience fainting, seizures or comas. Diabetes, drinking too much alcohol, certain medical conditions and tumors that produce insulin may cause low blood sugar.

Doctors use blood tests to diagnose low blood sugar, or patients can use blood sugar testing machines to measure their glucose levels, according to Healthline. Those suffering from low blood sugar can treat it by eating foods high in carbohydrates or by taking glucose tablets. After eating, people should test their blood sugar levels again in 15 minutes and eat carbohydrates until their glucose levels rise to normal levels. It is important that those treating themselves for low blood sugar do not overcompensate by ingesting too many carbohydrates and raising their glucose levels to above-normal levels.
