What causes hypertension?

The causes of hypertension can be divided into two main types. Primary hypertension has no specific underlying cause and develops slowly over many years. Secondary hypertension is caused by an underlying medical condition and can appear more suddenly than primary hypertension. Some conditions contributing to secondary hypertension can include kidney or thyroid problems, obstructive sleep apnea, some medications (e.g., contraceptive pills, pain relievers, cold remedies) or illegal drugs (e.g., cocaine and amphetamines).
