Get the Facts on Low Sugar Conditions

When the blood does not have enough glucose or sugar, a person has hypoglycemia. The muscles and cells in the body no longer have enough energy. This condition occurs most commonly as a side effect of diabetes mellitus, especially if a patient is taking insulin injections or oral hypoglycemic medication.

Hypoglycemia symptoms can be brought on by taking too much insulin, not sticking to the rigid meal schedule, or unusually prolonged or strenuous exercise. Stomach surgery, certain cancers, various drugs, alcohol, liver disease, and high fevers can also cause hypoglycemia.

Hypoglycemia Symptoms

Most hypoglycemic attacks start with a feeling of being hot and uncomfortable, leading to excessive sweating. Other symptoms include:

  • Dizziness
  • Weakness
  • Trembling
  • Hunger
  • Blurred vision
  • Slurred speech
  • Headache
  • Tingling in the lips or hands
  • Aggressiveness
  • Appearance of drunkenness
  • Seizures
  • Unconsciousness


Severe hypoglycemia symptoms or attacks can lead to a diabetic coma, however, most episodes are caught and treated before that happens. A person who experiences frequent attacks should avoid driving a car, operating heavy machinery, and even swimming.

If an attack goes undetected for a prolonged period, such as at night, there may be permanent brain damage.


The best treatment of hypoglycemia symptoms or attacks is the prevention of future attacks through the recognition of personal triggers and the recognition of initial signs. A person prone to episodes should always carry some sort of sugar, glucose tablets, or candy. Ingesting sugar at the onset can restore balance within a few minutes. Injections of glucose are available for people who have become unconscious.

A hypoglycemic person’s schedule of prescriptions and insulin should be reviewed with a doctor to check for any attack-causing combinations.
