Constant dizziness can be caused by irregular blood pressure, heart conditions, brain disorders, and some medications. It is important to seek medical attention for a proper diagnosis and early treatment.
There are many causes of constant dizziness. Irregular blood pressure affects the amount of oxygen the brain receives. There are also a variety of heart conditions that cause dizziness. Brain cancer or other ailments like stroke create the same symptom. Finally, dizziness is a side effect of many medications. Having the underlying condition diagnosed as early as possible ensures a better prognosis.
High and low blood pressure can cause constant dizziness. High blood pressure causes damage to the arteries and capillaries, while low blood pressure reduces the volume of blood going to the brain. The effect of both conditions is that less oxygen reaches the brain. Dizziness is a symptom of the brain’s inability to work at full capacity.
Heart conditions can also reduce the amount of blood reaching the brain. Irregular heart rhythms such as arrhythmia have this effect, as does heart disease. Illegal drugs that affect the heart can also create feelings of dizziness. Cocaine, for example, greatly increases the heart rate. The brain that gets too much blood creates the same dizziness symptom as too little blood.
Since the brain plays an important role in blood flow control, brain disorders are also responsible for constant dizziness. Brain tumors can cause an irregular heartbeat that disrupts normal blood; dizziness results as if you have a blood pressure disorder. Dizziness is also one of the earliest symptoms of a stroke, an event in which the brain is suddenly cut off from its blood supply. A less life-threatening cause associated with the brain is the sudden reduction in blood flow when a person quickly assumes a standing position.
Some medications are also known to cause constant dizziness. Dizziness is a common side effect of sedatives and tranquilizers. Some blood pressure medications and antidepressants are also responsible. Because of dizziness’s effect on cognitive function and reaction times, prescribed medications that cause this side effect usually carry a patient warning label.
If you experience constant dizziness, you need to see a doctor. A doctor will take a medical history and perform appropriate tests to diagnose the cause of your dizziness. Because the conditions and medications that cause dizziness usually have secondary symptoms, a patient shouldn’t wait long before receiving a diagnosis. Because some causes of dizziness are serious medical conditions, your best chance of a full recovery depends on getting medical attention as soon as possible.
