Symptoms- 2 types neuroglycopenia and hyperadrenalism. Neuroglycopenia- due to inadequate glucose delivery to the brain. Causes headache, confusion, dizziness, depression, drowsiness, fatigue, lethargy, mental or neurological impairment, visual disturbances. Hyperadrenalism- due to excessive catecholamine secretion in response to low or falling blood glucose. Symptoms- nervousness, anxiety, irritability, tremors, sweating, tachycardia, palpitations, insomnia, hunger, weakness.
Causes- two types; fasting hypoglycemia, reactive hypoglycemia. Fasting hypoglycemia- symptoms may be neuroglycopenic or hyperadrenergic and occur when a meal is skipped or during sleep. Can cause excessive fasting insulin levels or inadequate glucose release from liver. Treatment is to treat liver, pancrease, or hormonal disorders if present and maintain blood sugar with frequent low glycemic meals and snacks. Reactive hypoglycemia- symptoms may be neuroglycopenic or hyperadrenergic and occur after high glycemic meals or possibly other triggers (allergies and caffeine). Causes excessive or poorly regulated insulin secretion relative to blood sugar levels, insulin sensitivity abnormalities or glucagon disturbances. Treatment- treat insulin resistance, GI or pancreases disorders if present. Eliminate high glycemic foods and alcohol and can take chromium.
You can get hypoglycemic symptoms and not have hypoglycemia due to the adrenal gland kicking out things to stimulate the liver to make more glucose so glucose levels never drop (true hypoglycemia), but the symptoms can be present due to adrenal hormones.
