Endocrinal conditions
Beside adrenal gland diseases, other endocrinal conditions may cause hypertension, such as:
- Parathyroid diseases (hyperparathyroidism): Parathyroid glands secrete parathormone hormone (calcium-releasing hormone).
Parathyroid diseases – that increase parathormone- raise calcium levels in the blood which causes hypertension. - Thyroid diseases (hyperthyroidism or hypothyroidism):
Hypothyroidism increases the cholesterol levels in the blood, and this damages your arteries and reduces the elasticity of their walls causing hypertension.
Hyperthyroidism forces your heart to work harder and raises blood pressure. It also stimulates other causes of hypertension such as catecholamines secretion. - Pituitary diseases: pituitary tumours may increase the secretion of adreno-cortico-trophic hormone (ACTH). This raises the secretion of cortisol and ultimately causes hypertension.
