Hypertension Signs & Symptoms

Hypertension (high blood pressure) is a disease that can plague adults, babies and pregnant women. It is a chronic elevation in the blood pressure of the arteries. In order to ensure the body’s necessary blood circulation, the heart works very hard to pump blood faster and circulate despite the elevated blood pressure. Most hypertension patients experience no symptoms, even if their blood pressure is at lethal levels.

If you have been diagnosed with hypertension and live near Orlando, you could qualify for our high blood pressure clinical trial in DeLand, FL.

The measurement of blood pressure takes into account the heart’s beating and resting. The systolic measurement calculates the cardiac muscle contracting (systole) and the diastolic measurement calculates the relaxing of the cardiac muscle (diastole) between heartbeats as follows:

100-140 mmHg systolic pressure = normal
60-90 mmHg diastolic pressure

≥ 140 mmHg systolic pressure = hypertension
≥ 90 mmHg diastolic pressure

Hypertension Measurements


Hypertension Measurements    
Systolic Pressure (mmHg) Diastolic Pressure (mmHg)
 Pre-Hypertension  120-139  80-89
 Isolated Systolic Hypertension  ≥ 140  < 90
 Stage I Hypertension  140-159  90-99
 Stage II Hypertension  ≥ 160  ≥ 100
 Stage III Hypertension  ≥ 179  ≥ 109
 Hypertensive Crisis  ≥ 180  ≥ 110


Isolated systolic hypertension is common in elderly patients. It is characterized by an elevated systolic yet normal diastolic pressure.

Stage II hypertension accounts for about 7% of hypertension cases, the cases with underlying medical conditions ailing the heart, kidneys, endocrine system or arteries. The outstanding 93% of hypertension cases have no (apparent) underlying medical cause. Diseases that could cause hypertension include Crushing’s syndrome, thyroid disease and obesity.

Most people do not experience any symptoms from their hypertension no matter how high their blood pressure may be. However, among those adults who do experience signs of the disease, symptoms of hypertension include the following:

  • Dizzy spells
  • Hypertensive retinopathy
  • Nosebleeds
  • Headaches in the back of the head
  • Headaches in the morning
  • Vertigo
  • Palpitations
  • Tinnitus (buzzing or hissing sounds in the ears)
  • Lightheadedness
  • Fainting
  • Visual problems

Pregnant women with high blood pressure have a higher risk of developing pre-eclampsia, a disorder characterized by elevated blood pressure and protein in the pregnant mother’s urine. Pre-eclampsia can turn into eclampsia, a hypertensive crisis. Pre-eclampsia slices the chance of perinatal survival in half and accounts for 16% of maternal deaths. Symptoms in women with gestational hypertension include the following:

  • Headache
  • Stomach pain
  • Vomiting
  • Edema
  • Visual problems

Hypertensive crisis is lethally elevated blood pressure. The severely high blood pressure can cause fatal damage to bodily organs. Symptoms of hypertensive emergency include the following:

  • Headache
  • Dizziness
  • Visual deterioration
  • Trouble breathing
  • Malaise
  • Heart failure
  • Renal failure

Symptoms experienced by neonates, and infants and children with hypertension may include the following:

  • Irritability
  • Trouble breathing
  • Fatigue
  • Blurred vision
  • Nosebleeds
  • Facial paralysis
  • Seizures
  • Failure to thrive

Patients with hypertension have a greater risk of developing heart failure, heart attack, peripheral arterial disease, aortic aneurysm, chronic kidney disease and stroke. It is important to maintain a healthy diet and lifestyle in order to decrease blood pressure and limit health risks.
