Dizziness vs. Vertigo
Vertigo is the false sensation of self-movement or the movement of objects around you and it can be very debilitating. People with this type of dizziness often describe feelings of spinning, floating, swaying, tilting, or being pulled in one direction.
Episodes of vertigo can be triggered by simple body movements such as bending, turning your head, or rolling over in bed. The condition tends to come on abruptly and forcefully and may be accompanied by other troublesome symptoms such as nausea, vomiting, and abnormal eye movements called nystagmus.
What Are the Main Causes of Dizziness?
While dizziness is a symptom of many conditions, it rarely signals a life-threatening illness. Dizziness is most frequently caused by inner ear disturbances, such as an ear infection, benign paroxysmal positional vertigo (BPPV), or Meniere’s disease.
Sometimes dizziness may result from an underlying health condition within the heart and vascular system. This includes orthostatic hypotension, a sudden drop in blood pressure when you sit up or stand too quickly. Poor blood circulation from an irregular heartbeat or narrowed arteries may also cause spells of dizziness or lightheadedness.
Other Causes of Dizziness
People with anxiety disorders, low iron levels (anemia), low blood sugar or vision problems may experience generalized wooziness or foggy head feelings. Dizziness can also be the side effect of certain medications, such as anti-seizure drugs, antidepressants, sedatives, and blood pressure-lowering medications.
Less often, dizziness and vertigo are associated with brain-related conditions such as multiple sclerosis, Parkinson’s disease, migraine headache, or an injury to the head or neck. Sometimes dizziness occurs for no known reason. You’re also naturally at a higher risk for dizziness as you get older.
