Sudden dizziness and nausea are often associated with vertigo. Vertigo isnot a life-threatening condition, but it may indicate a deeper health issue. Migraines, benign positional vertigo, poor circulation, overheating, and infection are all possible causes of the nausea and dizziness associated with vertigo.

Nausea and Lightheadedness Due to Migraines

Sudden Nausea and DizzynessPeople who frequently get migraines may also be prone to experience dizziness or vertigo. These incidences of lightheadedness can last anywhere from several minutes to several hours, and may also include:

  • Sensitivity to light and noise
  • Nausea or vomiting

This type of vertigo can be treated with prescription medication based on your medical history and the persistence and severity of your migraines. One at-home treatment is to lie down in a quiet, dark room with a cold wash cloth covering your forehead until the symptoms subside.

BPV Causing Nausea and Dizziness

Benign Positional Vertigo (BPV) is the most common cause of vertigo, and it has been linked to other vertigo causing conditions such as inner ear infections and injury trauma. The sudden nausea and dizziness caused by BPV usually lasts about 30 seconds, but symptoms can last for days, weeks, or even months.

You are most likely to experience BPV after a change in head positions, which can elicit symptoms such as:

  • Nausea and vomiting
  • Blurred vision
  • Dizziness and lightheadedness
  • Loss of balance and unsteadiness

The best ways to treat BPV are through prevention and awareness. Incorporate gentle lighting in your home and avoid positions that trigger your BPV. Remain aware of your surroundings and limitations when experiencing BPV symptoms to prevent more serious injuries caused by falls.

Meniere’s Disease and Dizziness

Sudden Nausea and DizzinessMeniere’s disease, though more rare than some other vertigo inducing causes, is much more serious. The disease is linked to an excessive buildup of fluid in the inner ear, causing sudden vertigo that can last several hours.

Other symptoms of Meniere’s disease include:

  • Loss of hearing
  • Constant ringing sound (tinnitus)
  • Blocked or full feeling in the ear
  • Loss of balance
  • Headaches
  • Nausea and vomiting

While Meniere’s disease is a chronic illness, there are several treatments and lifestyle changes that can be adopted to ease the symptoms. Vestibular rehabilitation exercises typically help improve your sense of balance and decrease sensations of uneasiness.
