Low blood sugar, or hypoglycemia, is a condition that is characterized by having abnormally low levels of glucose in the bloodstream. Common symptoms of this condition may include feeling fatigued, irritable, weak or shaky; experiencing hunger pangs; having difficulty concentrating and making decisions; developing blurred vision; feeling lightheaded; sweating excessively and having palpitations.

Other physical signs associated with low blood sugar are pale skin colouration, cold hands and feet due to constriction of blood vessels from decreased oxygen supply as well as tingling sensations in different parts of the body. Additionally you may feel an urge to eat fresh fruits like apples or bananas as these foodstuffs are rich in glucose content which can help replenish hypoglycemic individuals’ body energy levels almost immediately.

It's important to note that those who have diabetes can experience especially severe cases of hypoglycemia because the pancreas is not able to produce enough insulin needed for regulating the sugar levels efficiently in their bodies. In such circumstances a balanced diet along with regular exercise play an even more important role than it does normally so be aware if you suffer from diabetes and act accordingly if symptoms arise. If left untreated long-term damage could result including serious nervous system problems - fainting, confusion and even comas may occur in extreme cases – so be sure to seek medical assistance!
