How is secondary hypertension different from primary hypertension according to the chapter?

Secondary hypertension is elevated blood pressure with a specific identifiable cause, while primary hypertension has no identifiable cause and accounts for 90% to 95% of cases. Secondary hypertension can often be corrected by addressing the underlying issue, whereas primary hypertension is typically managed through lifestyle changes and medication.

Primary hypertension, also known as essential or idiopathic hypertension, does not have a specific identifiable cause and is influenced by various factors such as genetics, lifestyle, and environmental factors. In contrast, secondary hypertension is caused by identifiable conditions such as renal disease, endocrine problems, or certain medications, and it accounts for 5% to 10% of hypertension cases. Treatment for secondary hypertension focuses on correcting the underlying cause, while primary hypertension management involves ongoing treatment to control blood pressure.
