Not all episodes of dizziness have a known cause. When a doctor can identify the underlying issue, it can cause further complications. The primary complication of dizziness itself involves becoming unsteady and falling. Anyone who may become dizzy should use a walking stick and avoid standing up or changing positions too quickly.

Treatment of dizziness depends on the cause and your symptoms. It's usually effective, but the problem may recur. These feelings may be triggered or worsened by walking, standing up or moving your head.
Your dizziness may be accompanied by nausea or be so sudden or severe that you need to sit or lie down. The episode may last seconds or days and may recur. 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:. Loop-shaped canals in your inner ear contain fluid and fine, hairlike sensors that help you keep your balance.
At the base of the canals are the utricle and saccule, each containing a patch of sensory hair cells. Within these cells are tiny particles otoconia that help monitor the position of your head in relation to gravity and linear motion, such as going up and down in an elevator or moving forward and backward in a car.
Dizziness has many possible causes, including inner ear disturbance, motion sickness and medication effects. Sometimes it's caused by an underlying health condition, such as poor circulation, infection or injury. The way dizziness makes you feel and your triggers provide clues for possible causes. How long the dizziness lasts and any other symptoms you have also help pinpoint the cause. Your sense of balance depends on the combined input from the various parts of your sensory system.
These include your:. Vertigo is the false sense that your surroundings are spinning or moving. Other than confusing your inner ear balance system by riding on a playground roundabout or the teacups ride at the fair, or by turning a load of pirouettes, then causes include:.
Read more about these conditions and other causes of vertigo in our separate leaflet called Vertigo. If, by dizziness, you mean feeling faint or light-headed, then conditions originating anywhere in your body may be the cause. For example:. People who feel faint often say they feel "light-headed" and feel as if they may collapse unless they sit or lie down. This is sometimes described as feeling dizzy. Most of us can remember times when we have felt like this.
For example, when we have been ill with a high temperature fever , very hungry, or very emotional. However, some people have repeated episodes of feeling faint without an obvious explanation such as a fever.
This means your blood pressure drops when you sit up from lying, or when you stand up from sitting or lying. In particular, if you jump up out of bed after a night's sleep. The fall in blood pressure is just for a short time as the blood pressure quickly adjusts to your new posture. However, in some people the fainting feeling can be more severe and last for a few minutes. This problem tends to get more troublesome as you become older.
The main symptom of anaemia is tiredness. However, if you have anaemia you may not get sufficient oxygen to the brain. This can make you feel light-headed. An arrhythmia is an abnormal heart rhythm. It occurs when the heart may suddenly beat too fast, too slowly, or in an abnormal way. There are various causes. One of the symptoms of an arrhythmia is to feel faint or light-headed as there may be a sudden decrease in blood supply to the brain as the arrhythmia develops.
See the separate leaflet called Abnormal Heart Rhythms Arrhythmias for more details. Various other heart disorders may cause a reduced flow of blood to the brain and cause you to feel faint or light-headed. In particular, if you have anxiety with panic attacks you can feel light-headed. This can get worse if you over-breathe hyperventilate due to the anxiety or panic attack. It is always worth reading the information leaflet that comes in the drug packet to check if dizziness is a recognised side-effect.
And if you mean the type of dizziness where you don't feel you or the room are spinning and you don't feel faint, but you just feel unbalanced, then there are yet more possible causes. These also can start from problems of various body organs and systems, such as your ear, your brain, your nervous system and your general state of health. Alcohol, street drugs and various medicines can also make you feel off-balance, and affect different people differently.
If you are getting recurring dizzy spells, or a constant dizziness for which there is no obvious cause, then see your doctor. If you have dizziness with other alarming symptoms such as sudden weakness in your arms, legs or face muscles, or chest pain or feeling very breathless , then call an ambulance or consult a doctor urgently.
It is usually best to have an explanation for dizziness. If you have a prolonged episode of dizziness, or recurring episodes of dizziness and are not sure what is causing them, then it is wise to contact a doctor.
