Final answer:
Secondary hypertension occurs when another condition, such as chronic kidney disease or an endocrine disorder like Cushing's disease, causes high blood pressure. These underlying health issues, alongside lifestyle factors like obesity and diabetes, greatly increase the risk of cardiovascular complications.
Step-by-step explanation:
Secondary hypertension is high blood pressure that is caused by another medical condition. While most cases of hypertension are primary and linked to genetic and lifestyle factors, about 10% are secondary. Chronic kidney disease and endocrine disorders such as Cushing's disease are common causes of secondary hypertension. Other conditions that may lead to secondary hypertension include obesity, diabetes, poor nutrition, lack of physical activity, and tobacco use. Persistent hypertension can lead to serious health issues like cardiovascular disease, including heart attacks, strokes, and peripheral artery disease, which underscore the importance of managing high blood pressure effectively.
