Which condition should raise suspicion for secondary hypertension?

Severe hypertension that is resistant to treatment is a key indicator of potential secondary hypertension. Secondary hypertension occurs when high blood pressure is caused by an underlying condition or issue, such as renal disease, endocrine disorders, or certain medications. In cases where individuals have severe hypertension that does not respond to standard treatment regimens, it is important to investigate further to identify any underlying factors contributing to this resistant hypertension.

For instance, conditions like primary aldosteronism or pheochromocytoma can lead to high blood pressure that is difficult to control with typical antihypertensive medications. Thus, the presence of severe hypertension that is resistant to standard therapies should prompt healthcare providers to conduct additional assessments and tests to explore potential secondary causes and tailor treatment accordingly.

While persistent headaches, occasional chest pain, and frequent fatigue can be associated with hypertension, they are less specific and not definitive indicators of secondary causes. These symptoms can be seen in primary hypertension and do not typically prompt the same level of concern regarding underlying pathologic conditions. Therefore, severe and resistant hypertension is the most critical scenario for considering secondary causes.
