Dizziness in Los Angeles is a word that is often used to describe two different feelings.
- Lightheadedness is a feeling that you are about to faint or “pass out.” Although you may feel dizzy, you do not feel as though you or your surroundings are moving. Lightheadedness often goes away or improves when you lie down. If lightheadedness gets worse, it can lead to a feeling of almost fainting or a fainting spell (syncope). You may sometimes feel nauseated or vomit when you are lightheaded. Primary care doctors often can help diagnose the cause of lightheadedness.
- Vertigo is a feeling that you or your surroundings are moving when there is no actual movement. You may feel as though you are off balance, spinning, whirling, falling, or tilting. When you have severe vertigo, you may feel very nauseated or vomit. You may have trouble walking or standing, and you may lose your balance and fall. Patients are often referred to an ENT specialist to determine the cause of vertigo.
It is common to feel lightheaded from time to time. Brief episodes of lightheadedness are not usually the result of a serious problem. Lightheadedness often is caused by a momentary drop in blood pressure and blood flow to your head that occurs when you get up too quickly from a seated or lying position (orthostatic hypotension). Lightheadedness treatment in Los Angeles may mean you have a more serious problem that needs to be evaluated.
Lightheadedness has many causes, including:
- Illnesses such as the flu or colds. Home treatment of your flu and cold symptoms usually will relieve lightheadedness.
- Vomiting, diarrhea, fevers, and other issues caused by dehydration.
- Very deep or rapid breathing (hyperventilation).
- Anxiety and stress.
- The use of tobacco, alcohol, or illegal drugs.
A more serious cause of lightheadedness is bleeding. Most of the time, the location of the bleeding and the need to seek medical care are obvious. But sometimes bleeding is not obvious (occult bleeding). You may have small amounts of bleeding in your digestive tract over days or weeks without noticing the bleeding. When this happens, lightheadedness and fatigue may be the first noticeable symptoms that you are losing blood. Heavy menstrual bleeding also can cause this type of lightheadedness.
Sometimes the cause of lightheadedness is an abnormal heart rhythm (arrhythmia), which can cause fainting spells (syncope). Unexplained fainting spells need to be evaluated by a doctor. You can check your heart rate by taking your pulse.
Many prescription and nonprescription medicines can cause lightheadedness or vertigo. The degree of lightheadedness or vertigo that a medicine causes will vary.
Vertigo occurs when there is conflict between the signals sent to the brain by various balance- and position-sensing systems of the body. Your brain uses input from four sensory systems to maintain your sense of balance and orientation to your surroundings.
- Vision gives you information about your position and motion in relationship to the rest of the world. This is an important part of the balance mechanism and often overrides information from the other balance-sensing systems.
- Sensory nerves in your joints allow your brain to keep track of the position of your legs, arms, and torso. Your body is then automatically able to make tiny changes in posture that help you maintain your balance (proprioception).
- Skin pressure sensation gives you information about your body’s position and motion in relationship to gravity.
- A portion of the inner ear, called the labyrinth, which includes the semicircular canals, contains specialized cells that detect motion and changes in position. Injury to or diseases of the inner ear can send false signals to the brain indicating that the balance mechanism of the inner ear (labyrinth) detects motion. If these false signals conflict with signals from the other balance and positioning centers of the body, vertigo may occur.
Common causes of vertigo include:
- Inner ear disorders, such as benign paroxysmal positional vertigo (BPPV), Ménière’s disease, vestibular neuritis, or labyrinthitis.
- Injury to the ear or head.
- Migraine-associated vertigo, which may or may not be associated with classic migraine symptoms such as headache or light and sound sensitivity
- Decreased blood flow through the arteries that supply blood to the base of the brain (vertebrobasilar insufficiency).
Less common causes of vertigo include:
- A noncancerous growth in the space behind the eardrum often causing infection (cholesteatoma).
- Brain tumors and cancer that has traveled from another part of the body (metastatic).
Alcohol and many prescription and nonprescription medicines can cause lightheadedness or vertigo. These problems may develop from:
- Taking too much of a medicine (overmedicating).
- Alcohol and medicine interactions. This is a problem, especially for older adults, who may take many medicines at the same time.
- Misusing or abusing a medicine or alcohol.
- Drug intoxication or the effects of withdrawal
See your doctor
Your ENT doctor in Los Angeles will talk to you about the history and symptoms of your vertigo and perform an ear and neurological exam. A Los Angeles hearing test and/or balance test may be ordered to diagnose the cause of vertigo.
Immediate medical attention is needed if vertigo occurs suddenly with a change in speech or vision or other loss of function. Vertigo that occurs with loss of function in one area of the body can mean a problem in the brain, such as a stroke or transient ischemic attack (TIA).
