I15: Secondary hypertension

I15.9: Secondary hypertension, unspecified

Secondary hypertension, unspecified, is a type of high blood pressure that is not the primary medical condition, but rather is a consequence of another disease. While most people with high blood pressure have primary hypertension, which has no identifiable cause and gradually develops over many years, secondary hypertension arises more quickly and becomes more severe. It is caused by an underlying health issue, but when it's unspecified, it means the cause is not particularly specified in the diagnosis. The underlying conditions may include kidney disease, adrenal gland disorders, certain heart defects, or the use of certain medications, among others. Symptoms may be similar to those of primary hypertension, and can include persistent headaches, fatigue, irregular heartbeat, chest pain, and difficulty breathing. It's important to manage secondary hypertension because if left untreated, it could lead to serious health problems like heart disease, stroke, and kidney disease.
