Besides the blood vessels in the brain, another group of susceptible arteries are those found in the nasal mucosa. In the event of high blood pressure, sometimes these tiny blood vessels are ruptured and start leaking out blood. Nosebleeds are more common in some patients but may never arise in others. Other causes of nose bleeding include low protein levels in the blood, sudden changes in altitude, temperature changes, prolonged sunlight exposure, and much more. Thus, by itself, nosebleed is not a leading sign to suspect hypertension.
During a hypertensive crisis, patients may display visible symptoms, such as facial flushing. It is a change in the colouration of the skin that results from the dilation of the superficial articles of the skin. Facial flushing is also common in other stressful events, especially in white people.
Patients with a heart condition usually have palpitations, especially when their blood pressure is high. In a hypertensive crisis, the heart pumps blood with an increased load, and if the patient has a heart condition, it is more likely to feel your heart racing or pounding. Patients with a heart rhythm problem should be extra careful because they are more likely to undergo cardiovascular complications.
