High blood pressure found to increase airway resistance and affect lung function

High blood pressure (hypertension) causes thickening of the blood vessels and hardening of the arteries (arteriosclerosis). A study conducted by Brazilian researchers has shown for the first time that a similar phenomenon occurs in the lungs. High blood pressure hardens the bronchi and increases airway resistance, impairing respiratory capacity.
