Balance problems can cause you to feel dizzy, as if the space is spinning, unsteady, or lightheaded. You might feel as if the space is spinning or you are going to subside. These feelings can happen whether you're lying down, sitting or standing.
Many body systems — including your muscles, bones, joints, eyes, the balance organ within the internal ear , nerves, heart and blood vessels — must work normally for you to possess normal balance. When these systems aren't functioning well, you'll experience balance problems.
Many medical conditions can cause balance problems. However, most balance problems result from issues in your balance organ within the internal ear (vestibular system).
Signs and symptoms of balance problems include:
Ø Sense of motion or spinning (vertigo)
Ø Feeling of faintness or lightheadedness (presyncope)
Ø Loss of balance or unsteadiness
Ø Falling or feeling like you might fall
Ø Feeling a floating sensation or dizziness
Ø Vision changes, such as blurriness
Balance problems are often caused by several different conditions. The cause of balance problems is usually related to the specific sign or symptom.
Sense of motion or spinning (vertigo)
Vertigo can be associated with many conditions, including:
Ø Benign paroxysmal positional vertigo (BPPV). BPPV occurs when calcium crystals in your internal ear — which help control your balance — are dislodged from their normal positions and move elsewhere within the internal ear . BPPV is that the commonest explanation for vertigo in adults. You might experience a spinning sensation when delivering bed or tilting your head back to seem up.
Ø Vestibular neuritis. This inflammatory disorder, probably caused by an epidemic , can affect the nerves within the balance portion of your internal ear . Symptoms are often severe and protracted , and include nausea and difficulty walking. Symptoms can last several days and gradually improve without treatment. This is a standard disorder second to BPPV in adults.
Ø Persistent postural-perceptual dizziness. This disorder occurs frequently with other sorts of vertigo. Symptoms include unsteadiness or a sensation of motion in your head. Symptoms often worsen once you watch objects move, once you read or once you are during a visually complex environment like a mall . This is the third most common disorder in adults.
Ø Meniere's disease. In addition to sudden and severe vertigo, Meniere's disease can cause fluctuating deafness and buzzing, ringing or a sense of fullness in your ear. The cause of Meniere's disease isn't fully known. Meniere's disease is rare and typically develops in people that are between the ages of 20 and 40.
Ø Migraine. Dizziness and sensitivity to motion (vestibular migraine) can occur thanks to migraine. Migraine is a common cause of dizziness.
Ø Acoustic neuroma. This noncancerous (benign), slow-growing tumor develops on a nerve that affects your hearing and balance. You might experience dizziness or loss of balance, but the foremost common symptoms are deafness and ringing in your ear. Acoustic neuroma is a rare condition.
Ø Ramsay Hunt syndrome. Also referred to as herpes zoster oticus, this condition occurs when a shingles-like infection affects the facial, auditory and vestibular nerves near one among your ears. You might experience vertigo, ear pain, facial weakness and deafness .
Ø Head injury. You might experience vertigo thanks to a concussion or other head injury.
Ø Motion sickness. You might experience dizziness in boats, cars and airplanes, or on amusement park rides. Motion sickness is common in people with migraines.
Feeling of faintness or lightheadedness
Lightheadedness can be associated with:
Ø Hemodynamic orthostatic hypotension (postural hypotension). Standing or sitting up too quickly can cause some people to experience a big drop by their vital sign, leading to feeling lightheaded or faint.
Ø Cardiovascular disease. Abnormal heart rhythms (heart arrhythmia), narrowed or blocked blood vessels, a thickened heart muscle (hypertrophic cardiomyopathy), or a decrease in blood volume can reduce blood flow and cause lightheadedness or a fainting feeling.
Loss of balance or unsteadiness
Losing your balance while walking, or feeling imbalanced, may result from:
Ø Vestibular problems. Abnormalities in your internal ear can cause a sensation of a floating or heavy head and unsteadiness within the dark.
Ø Nerve damage to your legs (peripheral neuropathy). The damage can lead to difficulties with walking.
Ø Joint, muscle or vision problems. Muscle weakness and unstable joints can contribute to your loss of balance. Difficulties with eyesight also can lead to unsteadiness.
Ø Medications. Loss of balance or unsteadiness are often a side effect of medicines .
Ø Certain neurological conditions. These include cervical spondylosis and Parkinson's disease.
A sense of dizziness or lightheadedness may result from:
Ø Inner ear problems. Abnormalities of the vestibular apparatus can cause a sensation of floating or other false sensation of motion.
Ø Psychiatric disorders. Depression (major depressive disorder), anxiety and other psychiatric disorders can cause dizziness.
Ø Abnormally rapid breathing (hyperventilation). This condition often accompanies anxiety disorders and should cause lightheadedness.
Ø Medications. Lightheadedness can be a side effect of medications.
