Depression is a symptom of hypoglycemia. When the blood sugar level drops below a certain level, the brain is starved of glucose. Then the pituitary gland sends an urgent message to the adrenal glands to pour adrenaline into the blood stream. Adrenaline converts glycogen into glucose,thus raising the blood sugar level. You will feel depressed when the brain lacks glucose.
