What Is Hypertension?

Hypertension, also called high blood pressure, means your blood pushes too hard against the walls of your arteries. Over time, this pressure can damage your heart, blood vessels, and kidneys. It's often called a 'silent- disease because many adults in Houston live with it without knowing. Early detection and care help you avoid serious complications.

Common Causes and Risk Factors

  • Family history - Having parents or siblings with high blood pressure raises your risk.
  • High-salt diet - Eating too many salty or heavily processed foods increases blood pressure.
  • Lack of exercise - A sedentary lifestyle puts extra strain on your heart.
  • Overweight or obesity - Extra body weight forces your heart to work harder.
  • Age and ethnicity - Rates rise after age 60, and African American adults are at higher risk.

Signs and Symptoms

  • Often none in early stages (hence 'silent-)
  • Morning headaches
  • Dizziness or lightheadedness
  • Blurred vision
  • Occasional nosebleeds when pressure is very high

How Dr. Rishi Chadha Diagnoses Hypertension

1. Blood Pressure Check

Readings are taken twice using accurate, calibrated equipment to ensure precise measurements.

2. Health History Review

Dr. Chadha evaluates your family history, diet, lifestyle habits, and any current symptoms to identify key risk factors.

3. Lab Tests

Comprehensive blood and urine tests assess your heart and kidney health and uncover any underlying issues.

4. Heart and Vessel Imaging

  • Electrocardiogram (ECG) to check heart rhythm and function
  • Ultrasound or other noninvasive imaging to visualize arterial health
