What is the most common ideology for an 18-year-old with persistent hypertension, in the absence of clear evidence pointing to a secondary cause?

From the Guidelines

The most common etiology for an 18-year-old with persistent hypertension without clear evidence of a secondary cause is essential (primary) hypertension. While secondary causes should be considered in young patients, essential hypertension is becoming increasingly prevalent in adolescents due to rising rates of obesity, sedentary lifestyle, and poor dietary habits 1. Initial management should focus on lifestyle modifications including:

• Weight reduction if overweight
• Regular physical activity (30-60 minutes most days)
• Dietary sodium restriction (<2300 mg/day)
• A diet rich in fruits, vegetables, and low-fat dairy products

If blood pressure remains elevated despite 3-6 months of lifestyle changes, pharmacologic therapy may be necessary. First-line medications typically include:

• ACE inhibitors (like lisinopril 5-10 mg daily)
• ARBs (such as losartan 25-50 mg daily)
• Calcium channel blockers (amlodipine 2.5-5 mg daily)

These medications are generally well-tolerated in young adults 1. Regular blood pressure monitoring is essential, with a goal of <130/80 mmHg 1. The pathophysiology involves complex interactions between genetic predisposition and environmental factors leading to increased peripheral vascular resistance and cardiac output, ultimately resulting in sustained blood pressure elevation. It's worth noting that secondary hypertension is relatively rare, accounting for only 5%–10% of hypertensive patients, and is often caused by renal parenchymal disease, renovascular hypertension, primary aldosteronism, chronic sleep apnea, or substance/drug-induced hypertension 1.

From the Research

Most Common Ideology for Hypertension in an 18-Year-Old

• The most common ideology for an 18-year-old with persistent hypertension, in the absence of clear evidence pointing to a secondary cause, is primary hypertension 2, 3.
• Primary hypertension is also known as essential hypertension, and it is the most common form of hypertension, accounting for about 90-95% of cases 3.
• The exact cause of primary hypertension is not known, but it is thought to be related to a combination of genetic and environmental factors, such as diet, lifestyle, and stress 2.

Secondary Causes of Hypertension

• Secondary hypertension, on the other hand, is caused by an underlying medical condition, such as kidney disease, sleep apnea, or adrenal gland tumors 2, 3.
• The most common causes of secondary hypertension in young adults include renal parenchymal disease, coarctation of the aorta, and obstructive sleep apnea 2, 3.
• It is essential to rule out secondary causes of hypertension, especially in young adults, as they may be more likely to have an underlying condition that can be treated 2, 3.

Diagnosis and Treatment

• The diagnosis of primary hypertension is made by excluding secondary causes of hypertension and assessing the patient's overall health and medical history 2, 3.
• Treatment for primary hypertension typically involves lifestyle modifications, such as diet and exercise, and medication, such as diuretics, beta blockers, or ACE inhibitors 4, 5, 6.
• The choice of treatment depends on the individual patient's needs and medical history, and may involve a combination of medications and lifestyle modifications 4, 5, 6.
