You likely think of high blood pressure leading to a heart attack. It can. But one major side effect is an aneurysm. An aneurysm is a bulge in a weakened wall of your artery—imagine air being blown into a balloon. If the pressure is high, the more likely your vessels are to be weakened and bulge out. Eventually, the aneurysm may burst, which can lead to blood clots, massive bleeding or a stroke. Other side effects of high blood pressure include:

  • Heart Attack
  • Stroke
  • Heart Failure. …
  • Kidney Issues, due to weakened blood vessels
  • Metabolic Syndrome
  • Memory Issues or Dementia.

"Hypertension Stage 1 is when blood pressure consistently ranges from 130-139 systolic or 80-89 mm Hg diastolic. At this stage of high blood pressure, doctors are likely to prescribe lifestyle changes and may consider adding blood pressure medication based on your risk of atherosclerotic cardiovascular disease (ASCVD), such as heart attack or stroke," says the AHA.

"This stage of high blood pressure requires medical attention. If your blood pressure readings suddenly exceed 180/120 mm Hg, wait five minutes and then test your blood pressure again. If your readings are still unusually high, contact your doctor immediately. You could be experiencing a hypertensive crisis. If your blood pressure is higher than 180/120 mm Hg and you are experiencing signs of possible organ damage such as chest pain, shortness of breath, back pain, numbness/weakness, change in vision or difficulty speaking, do not wait to see if your pressure comes down on its own. Call 911." And to get through this pandemic at your healthiest, don't miss these 35 Places You're Most Likely to Catch COVID.
