Aside from bad lifestyle habits and family history, high blood pressure can be caused by other medical conditions. This is usually known as secondary hypertension.

There are numerous diseases that can lead to hypertension, including:

Kidney diseases

  • Diabetes complications. Kidney dysfunction is a common complication of diabetes. As diabetes damage the filtering system of your kidneys, your blood pressure will be elevated.
  • Glomerular disease. The filters in your kidneys are fragile and can be swollen due to many reasons. When this happens, you will likely develop hypertension as well.
  • Polycystic kidney disease. Another kidney condition that can result in hypertension is polycystic kidney disease. Polycystic kidney disease forms cysts in your kidneys, making them unable to work properly.
  • Renovascular hypertension. The arteries leading to the kidneys can be narrowed down by fat deposits or abnormal muscle growth in the artery wall, causing hypertension.

Hormone-related conditions

  • Cushing syndrome. Also known as hypercortisolism, cushing syndrome is a condition which occurs when your body produces too much cortisol. Most people with cushing syndrome develop hypertension.
  • Aldosteronism. This type of hypertension is caused by an excessive level of aldosterone. Aldosteronism is responsible for salt and water retention as well as potassium loss, which consequently leads to hypertension.
  • Pheochromocytoma. Pheochromocytoma occurs when a rare tumor grows in the adrenal gland, stimulating the production of adrenaline and noradrenaline. These two hormones in large amount will spike your blood pressure and may lead to long-term hypertension.
  • Thyroid problems. Hypertension can appear when your thyroid gland does not work the way it is supposed to, producing either too much or too few thyroid hormone.
  • Hyperparathyroidism. The levels of calcium and phosphorus in your bloodstream are regulated by the parathyroid gland. Imbalance amount of parathyroid hormone causes the calcium level in your blood to rocket, resulting in high blood pressure.

Sleep apnea

People with sleep apnea snore repeatedly and loudly. During their sleep, they may stop breathing, leading to oxygen deprivation. Insufficient oxygen intake weakens the blood vessels, increasing your blood pressure.


Obese people usually have problems with their blood circulation. The heavier your body is, the more pressure is put on your artery walls. Increased heart rate and fat deposits also contribute to hypertension.

Treatment for secondary hypertension requires the underlying medical condition to be taken care of. As soon as you get rid of the cause, your blood pressure will be managed, perhaps even returns to normal.
