Dizziness
Dizziness and fainting, or syncope, is another symptom of pulmonary hypertension. Syncope is often caused by a lack of blood flow or oxygen to the brain. Lightheadedness does not always lead to syncope, but it does indeed put you at risk for losing consciousness, especially when you experience shortness of breath and erratic cardiac rhythms.
When the lungs cannot oxygenate blood properly, the body and brain become starved of energy. Before becoming dizzy, you might start to feel sluggish and suffer from brain fog. If this is paired with other symptoms on this list, be sure to call a medical professional as soon as possible, since dizziness and fainting can be dangerous.
