What Can Cause Dizziness: Why Am I Dizzy

Vertigo (dizziness) is a very common symptom that is linked to many diseases. Trying to find the source of the problem can be very challenging, since this is a typical symptom that may be caused by innumerable underlying health conditions. Below you will discover a short list of disorders that are linked to intermittent or frequent vertigo.

Reasons For Dizziness

Medical professionals will begin the diagnosing process, by obtaining a thorough medical history and then followed up with a physical exam. You may need to undergo some diagnostic testing to get down to the root of the problem. One of the most common conditions that is linked to vertigo is otitis media (middle ear infection).

The middle ear is made up of the eardrum, incus, malleus stapes, and Eustachian tubes. Inflammation and fluid will build up in the middle ear, which can turn to infection, if not treated properly. Chronic otitis media is often caused by allergies and reoccurring ear infections.

  • Fever
  • Poor hearing
  • Pus or fluid drainage from affected ear
  • Vertigo
  • Poor balance

Causes For Dizziness

Benign Paroxysmal Positional Vertigo is one of the most common vestibular disorders. The condition normally begins in the inner ear sensory organs such as the Organ of Corti, which is located inside of the cochlea (hearing organ). The Organ of Corti houses microscopic hair cells that are the hearing nerve receptors.

Another sensory organ is the utricle, which is partially made up on otoconia (calcium carbonate crystals). These crystals can break loose from the utricle and become lodged in the semicircular canals. These canals are responsible for controlling balance and when they become altered by the loosened otoconia, the individual will experience vertigo.

There are many factors that are linked to BPPV disorder including:

  • Age
  • Trauma
  • Infection

The symptoms of BPPV can be triggered by sudden positional changes of the head. Sitting up too quickly can also trigger intermittent vertigo, lightheadedness, nausea/vomiting, and imbalance sensation.

What Causes Dizzy Spells

Meniere’s disease is another condition that may be the source of your vertigo. This condition is linked to fluid (endolymph) buildup in the labyrinth (holds organs of balance and the cochlea). When this occurs, the individual will experience a sense of imbalance, vertigo, and poor hearing.

Many medical researchers have other theories of Meniere’s such as constriction of blood vessels, which is often caused by migraines. Viral infections and allergies also may be linked to Meniere’s.

This vestibular disorder is hereditary and involves an abnormality of the endolymph regulatory factors. Symptoms of Meniere’s include:

  • Tinnitus (ringing in ears)
  • Temporary loss of hearing
  • Vertigo episodes, which may last for 1-20 minutes
  • Fullness sensation in the ear

Migraine

Migraines are classified as moderate to severe head pain, which may include a pulsating sensation unilaterally (one side of the head). Light sensitivity, nausea, vomiting, temporary vision loss, and vertigo are also other symptoms of this condition. Some factors that are linked to migraines:

  • Extreme anxiety and stress
  • Insomnia
  • Improper eating habits
  • Over-exposure to sunlight and bright lights
  • Female hormonal alterations

Constrictions of the blood vessels that are located in the head is often linked to migraines.

Causes Of Dizzy Spells

When experiencing a bout of intermittent vertigo, everyone will question dizzy spells causes, because they are very disturbing. Orthostatic hypotension, alterations in blood pressure levels, which are linked to quick positional changes. This is a very common disorder that is often treated with blood pressure medications, but the individual will also have to learn to make slow positional changes, especially, when standing and sitting up.

Dizziness And Cause

Cardiovascular disorders are also linked to vertigo, since these diseases can cause alterations in the blood volume that flows to the brain and inner ear. Myocardial infarction (heart attack), and arrhythmia (irregular heart beat). Mini-strokes (transient ischemic attack) are caused by ischemia (loss of blood flow).

Anemia is classified as low serum red blood cells, which are responsible for carrying oxygen to tissues throughout the body. This condition is often caused by recent surgical procedures, trauma, poor diet, bleeding ulcers, and specific medications that alter the production of RBCs.
