Hypertension
Increased blood pressure can also be a causative factor behind pulsatile type of tinnitus. Increased density and pressure of the blood against the walls, may trigger tinnitus. The sound pattern corresponds with the pulse of the patient or may be heard as a quick whooshing sound. Hypertension induced tinnitus is a manifestation of the anatomical layout of the vessel in and around the ears. Antihypertension medications are also a reason of this association; 44% of tinnitus patients are also found to be hypertensive. Some loop diuretics are ototoxic. Hypertension is the most common reason in pregnancy-associated tinnitus, where it is known as preeclampsia.
