Inflammation of the lungs does not cause hypertension. Inflammation of the lungs is an infection of the lungs with a fine average virus or fungus. Patients with lung inflammation may present with fever, cough, and sputum; it does not affect blood pressure. If the lung infection induces pulmonary encephalopathy or respiratory failure, it can cause low blood pressure, which is more dangerous. There are many causes of hypertension, such as genetic factors, and genetic factors tend to play a bigger role in primary hypertension. Long-term mental stress, poor rest or emotional stress can easily cause hypertension, as well as chronic kidney disease can also cause blood pressure to rise.
