What is Causing Your Dizziness?

Have you ever stood up quickly and felt dizzy? Or maybe experienced a rush of dizziness while talking to coworkers at work? You aren’t alone. In fact, approximately 40% of the U.S. population will experience some form of dizziness or balance complications at some point during their lifetime. 

Dizziness is a term used to describe a range of sensations, including feeling as though the room is spinning, lightheadedness, and feeling unsteady. There are many possible causes of dizziness, which may relate to a person’s external environment, medications being taken, or an underlying condition. Recurring dizziness or severe dizzy spells can significantly affect a person’s quality of life. 

Causes of dizziness

The causes of dizziness can range from temporary physical changes to more serious medical conditions. Here are the most common explanations for why you may be feeling dizzy:


Vertigo is one of the most common balance disorders. Similar to motion sickness, those who suffer from vertigo experience a spinning sensation while standing, sitting, or walking. Vertigo can develop suddenly and last for a few seconds or much longer. Vertigo is commonly caused by a problem with the way balance works in the inner ear, although it can also be caused by problems in certain parts of the brain. Causes of vertigo may include:

  • Benign paroxysmal positional vertigo (BPPV) – where certain head movements trigger vertigo
  • Migraines – Severe headaches
  • Labyrinthitis – an inner ear infection

Symptoms associated with vertigo may include:

  • Loss of balance
  • Feeling sick or being sick
  • Dizziness 


Migraine is a common health condition, affecting 39 million people in the U.S., according to the Migraine Research Foundation. A migraine is a moderate or severe headache that causes a throbbing or pulsing pain on one side of the head. Common symptoms of a migraine include nausea, vomiting, and increased sensitivity to light or sound. Sometimes individuals experience dizziness before the onset of a migraine episode. 

Low blood pressure

Low blood pressure can cause noticeable signs and symptoms, such as dizziness or lightheadedness, nausea, fainting, and blurred vision. Postural hypotension is low blood pressure caused by standing up too quickly and can happen to anyone for a variety of reasons, such as dehydration, lack of food, or being overly fatigued. 

Motion sickness

The brain senses movement by getting signals from the inner ears, eyes, muscles, and joints. When it gets signals that do not match, a person can get motion sickness. 

Motion sickness usually occurs when you’re traveling by car, boat, plane, or train. Motion sickness can start with a sudden queasy feeling and can eventually lead to dizziness, nausea, and vomiting. 

Low iron

Iron deficiency can result in dizziness, shortness of breath, chest pain, and fatigue. One may consider making appropriate dietary changes or taking iron supplements to treat their iron deficiency. Always speak with your healthcare provider before beginning a new supplement.
