what causes dizziness and weakness
The term "dizziness" is used to indicate a variety
of feelings, such as feeling weak, dizzy, faint, or unstable. Vertigo is a type
of dizziness where you unintentionally believe that you or your surroundings
are spinning or moving.
One of the more frequent conditions that send adults to the
doctor is dizziness. Your life can be profoundly impacted by frequent or
ongoing dizziness. However, feeling lightheaded infrequently indicates a
serious illness.
Depending on the cause and your symptoms, dizziness can be
treated. Although it frequently solves the issue, it might do it again.
Symptoms
Dizziness can be experienced as a variety of different
experiences, including some of the following:
- A fictitious feeling of motion or spinning (vertigo)
- A sense of faintness or dizziness
- Being unsteady or off-balance
- A sensation of weightlessness, wooziness, or floating
Walking, standing up, or moving your head may cause these
emotions to appear or become worse. You might feel sick along with your
dizziness, or it could come on suddenly or be so strong that you need to sit or
lie down. The event could last just a few seconds or for several days.
when to
visit the doctor
Traditionally, you should visit your doctor if you feel any
persistent, sudden, severe, or protracted vertigo or dizziness.
Seek immediate medical attention if any of the following
occur along with sudden, severe vertigo or dizziness:
- An unexpectedly bad headache
- chest pain
- Having trouble breathing
- Arms or legs that are numb or paralyzed
- Fainting
- dual perception
- irregular or fast heartbeat
- Slurred or confused speech
- stumbles or has trouble walking
- persistent vomiting
- Seizures
- An abrupt shift in hearing
- numbness or weakness in the face
Causes
There are several potential reasons of dizziness, such as
inner ear disturbances, motion sickness, and drug interactions. There are times
when an underlying medical problem, such as poor circulation, an infection, or
an injury, is to blame.
Your symptoms and triggers can give you information about
potential causes of dizziness. Your other symptoms and how long the dizziness
lasts all aid in determining the cause.
issues
with the inner ear that produce vertigo (vertigo)
The input from all of your sensory system's components
working together is what gives you a sensation of equilibrium. These comprise
you:
eyes, which
let you to see where and how your body is moving in space.
Sensory
nerves, which communicate with the brain regarding motions and
locations of the body
Sensors in the inner
ear, which also serve as a back-and-forth motion detector
The unfounded sensation that your surroundings are spinning
or moving is known as vertigo. When you have an inner ear issue, your brain
receives messages from your inner ear that don't match the signals coming from
your eyes and sensory nerves. As your brain tries to make sense of the jumble,
vertigo sets in.
harmless
recurrent positional vertigo (BPPV).
This disorder gives you an acute, fleeting, but deceptive,
sensation of movement or spinning. A sudden shift in head movement, such as
when you sit up, turn over in bed, or receive a hit to the head, sets off these
episodes. The most typical cause of vertigo is BPPV.
Infection.
Vestibular neuritis, a viral infection of the vestibular
nerve, can result in severe, ongoing dizziness. You might have labyrinthitis if
you also experience sudden hearing loss.
Meniere's
disorder.
This condition causes an excessive accumulation of fluid in
your inner ear. It is characterized by brief yet intense episodes of vertigo
that can last for several hours. Additionally, you can encounter variable
hearing loss, ringing in the ears, and the sensation of an ear plug.
Migraine.
Even when they are not experiencing a severe headache, those
who suffer from migraines may experience vertigo or other types of dizziness.
These vertigo episodes may be accompanied by headaches, light sensitivity, and
noise sensitivity, and they can last anywhere from minutes to hours.
Dizziness
is a result of circulatory issues
If not enough blood is being pumped to your brain, you can
experience lightheadedness, faintness, or unsteadiness. Several causes are:
blood
pressure decline
You may have momentary dizziness or a feeling of faintness
if your systolic blood pressure, which is the higher number in your blood
pressure reading, drops dramatically. When standing or sitting up too rapidly,
it can happen. Orthostatic hypo tension is another name for this disorder.
blood
circulation problems.
Dizziness may be brought on by diseases such cardiomyopathy,
heart attacks, heart arrhythmias, and transient ischemia attacks. Additionally,
a drop in blood volume could result in insufficient blood supply to your brain
or inner ear.
OTHER ROOT CAUSES OF DIZZINESS
neurological
disorders. Progressive loss of balance can be a symptom of some
neurological conditions, including Parkinson's disease and multiple sclerosis.
Medications. Certain
pharmaceuticals, including anti-seizure medications, antidepressants,
sedatives, and tranquilizers, can cause dizziness as a side effect. In
particular, if blood pressure-lowering drugs drop your blood pressure too much,
they could make you feel faint.
anxiety
conditions. Some anxiety problems can make you feel faint or wobbly,
which is sometimes referred to as dizziness. Panic attacks and a fear of
leaving the house or being in wide-open spaces are a few of them (agoraphobia).
low
levels of iron (anemia). Dizziness is just one of the indications
and symptoms of anemia; other signs and symptoms include weakness, pale
complexion, and weariness.
lower blood sugar (hypoglycemia). People with diabetes who use insulin are more likely to develop this illness. Sweating and nervousness may also accompany dizziness (lightheartedness).
poisoning
from carbon monoxide. The "flu-like" signs and symptoms of
carbon monoxide poisoning include headache, dizziness, weakness, upset stomach,
vomiting, chest discomfort, and confusion.
Dehydration
and overheating. You could have lightheartedness as a result of
overheating (hypothermia) or dehydration if you exercise in hot conditions or
if you don't drink enough water. Particularly if you take specific heart drugs,
this is true.
danger
signs
Your likelihood of feeling lightheaded could be affected by
the following factors:
Age. Medical
disorders that make people feel lightheaded, especially an imbalance, are more
common in older people. They are also more likely to take drugs that can make
you feel lightheaded.
an
attack of vertigo in the past. You are more likely to become
lightheaded in the future if you have previously felt lightheaded.
Common
complication
Your chance of falling and hurting yourself increases if
you're feeling dizzy. Driving a car or using heavy machinery while feeling
queasy increases the risk of an accident. In addition, delaying treatment of a
pre-existing medical problem that may be the source of your wooziness could
have long-term effects.
