High blood pressure and dizziness are often associated because a person with uncontrolled hypertension may present with dizziness; indeed, dizziness may be the only symptom of hypertension.
In some cases, people with high blood pressure may have a pounding feeling in their head or chest, a feeling of lightheadedness or dizziness, or other signs. Without symptoms, people with high blood pressure may go years without knowing they have the condition.
Sudden Dizziness
Dizziness and feeling slightly off balance are early warning signs of a stroke caused by high blood pressure. These symptoms occur due to lack of oxygen supply to the brain. If the dizziness has to do with standing up too fast or watching a sped-up video, it's probably nothing to worry about.
A sudden fall in blood pressure can be dangerous. A change of just 20 mm Hg — a drop from 110 mm Hg systolic to 90 mm Hg systolic, for example — can cause dizziness and fainting.
In most cases, dizziness associated with heart problems is accompanied by other symptoms. These may include shortness of breath, swollen extremities, frequent fatigue or chest pain. In the event heart disease is suspected, you will undergo one or more tests to get to the root of your problem.
Generally, see your doctor if you experience any recurrent, sudden, severe, or prolonged and unexplained dizziness or vertigo. Get emergency medical care if you experience new, severe dizziness or vertigo along with any of the following: Sudden, severe headache. Chest pain.
Still, you can make lifestyle changes to bring your blood pressure down. Something as simple as keeping yourself hydrated by drinking six to eight glasses of water every day improves blood pressure. Water makes up 73% of the human heart,¹ so no other liquid is better at controlling blood pressure.
Your brain needs a steady supply of oxygen-rich blood. Otherwise, you can become lightheaded and even faint. Some causes of low blood flow to the brain include blood clots, clogged arteries, heart failure, and an irregular heartbeat. For many older people, standing suddenly can cause a sharp drop in blood pressure.
Having high blood pressure can trigger feelings of anxiety in some people. Those whom doctors diagnose with hypertension may worry about their health and their future. Sometimes, the symptoms of hypertension, which include headaches, blurred vision, and shortness of breath, can be enough to cause panic or anxiety.
Often, your body sends signs that your heart needs care—symptoms you should not ignore. These include chest pain, shortness of breath, heart palpitations, loss of consciousness, and dizziness.
Malignant hypertension is very high blood pressure that comes on suddenly and quickly. The kidneys filter wastes and excrete fluid when the pressure of blood in the bloodstream forces blood through the internal structures of the kidney.
Dizziness (lightheadedness) is a common symptom that's not usually a sign of anything serious, but should be investigated by a doctor.
Some of the main causes are: dehydration(not having enough fluids in your body) a drop in blood pressure when you stand up quickly. feelings of anxiety or panic.
In general, if dizziness lasts longer than a few days, or is severe enough to keep you from normal activities, you should talk with your doctor. Depending on the cause, there are medications and physical therapy options that may give you some relief.
Warning signs and symptoms of heart failure include shortness of breath, chronic coughing or wheezing, swelling, fatigue, loss of appetite, and others.
Additional symptoms of a clogged artery may include: Dizziness or weakness. Heart palpitations, or sensations of your heart racing or fluttering. Nausea or sweating.
It's the leading cause of stroke. Carotid artery disease limits the amount of blood and oxygen that reaches your brain, which can cause vertigo or dizziness. Carotid artery disease may not exhibit any symptoms before causing ischemia or a full-blown stroke.
