Just found something of interest -:
Hypoglycemia can also be caused by a problem with the pituitary or adrenal glands, the pancreas, or the liver. The pituitary gland controls the body's production of hormones needed to raise the body's blood sugar levels if they fall too low. These hormones include adrenaline and cortisol, which are released from the adrenal glands, and glucagon, which is released from the pancreas. These hormones all help raise blood sugar levels. If they are not working properly, this could cause hypoglycemia.
