Blood pressure

Understanding Blood Pressure

Blood pressure is the force of blood pushing against the walls of your arteries. It’s measured in millimeters of mercury (mmHg) and recorded with two numbers: systolic pressure (when the heart beats) and diastolic pressure (when the heart rests between beats). A normal reading is around 120/80 mmHg.

Initial Symptoms of High Blood Pressure

High blood pressure, or hypertension, is often called the “silent killer” because it may not show symptoms. When symptoms do occur, they might include:

  • Headaches: Frequent or severe headaches can be an early sign.
  • Dizziness: Feeling lightheaded or dizzy.
  • Nosebleeds: Unexplained nosebleeds may occur.
  • Shortness of breath: Difficulty breathing without exertion.
  • Blurred vision: Vision problems can develop.

Causes of High Blood Pressure

Several factors can contribute to this problem, including:

  • Genetics: Family history of hypertension.
  • Unhealthy diet: High salt and fat intake.
  • Lack of physical activity: Sedentary lifestyle.
  • Obesity: Excess body weight.
  • Smoking: Tobacco use.
  • Excessive alcohol: Drinking too much alcohol.
  • Stress: Chronic stress can elevate blood pressure.
