High blood pressure can be a symptom of chronic kidney disease, states the National Kidney Foundation. It can also be a symptom of atherosclerosis in the arteries leading to the kidneys and adrenal gland tumors, according to Mayo Clinic. Thyroid disease and obstructive sleep apnea also cause high blood pressure.
Not only is high blood pressure a sign of chronic kidney disease, but high blood pressure makes a person more susceptible to chronic kidney disease in the first place, claims the National Kidney Foundation. This is especially true if a patient belongs to an ethnic group that tends to suffer from high blood pressure, such as African Americans, Native Americans and Pacific Islanders.
An adrenal tumor that is producing excessive amounts of steroid hormone can lead to a condition called Cushing's syndrome, according to the Center for Pancreatic and Biliary Diseases at the University of Southern California Department of Surgery. One of the symptoms of Cushing's syndrome is high blood pressure. An adrenal tumor that produces too much aldosterone or catecholamines can also cause high blood pressure in a patient.
Hyperthyroidism can also cause the blood pressure to go up, according to WebMD. It can also cause tachycardia and heart palpitations.
