Are pulmonary hypertension and just hypertension two different things? -

Hypertension is high blood pressure. Blood pressure is the force of blood pushing against the walls of arteries as it flows through them. Arteries are the blood vessels that carry oxygenated blood from the heart to the body s tissues. Hypertension is a major health problem, especially because it has no symptoms. Many people have hypertension without knowing it. The American Heart Association considers blood pressure less than 140 over 90 normal for adults. Pulmonary arterial hypertension is a progressive disorder characterized by abnormally high blood pressure (hypertension) in the pulmonary artery, the blood vessel that carries blood from the heart to the lungs. Hypertension occurs when most of the very small arteries throughout the lungs narrow in diameter, which increases the resistance to blood flow through the lungs. To overcome the increased resistance, pressure increases in the pulmonary artery and in the heart chamber that pumps blood into the pulmonary artery (the right ventricle). Signs and symptoms of pulmonary arterial hypertension occur when increased pressure cannot fully overcome the elevated resistance and blood flow to the body is insufficient. Shortness of breath (dyspnea) during exertion and fainting spells are the most common symptoms of pulmonary arterial hypertension. People with this disorder may experience additional symptoms, particularly as the condition worsens. Other symptoms include dizziness, swelling (edema) of the ankles or legs, chest pain, and a racing pulse.

pulmonary hypertension is related to the respiratory system. there are many causes for hypertension but remember hypertension is a symptom not a disease. good luck.

They are two different things. One occurs only in the lungs and they other one occurs throughout the entire vascular system.

yah both are different
