Hypoglycemia has a variety of causes, including diabetes treatment, medications, alcohol abuse and medical conditions, explains Healthline. Low blood sugar levels often occur when diabetes patients inject too much insulin and do not eat enough food to compensate for it. Hypoglycemia often triggers sudden symptoms, such as blurry vision, unexplained fatigue, hunger and sweating.

Causes of low blood pressure, called hypotension, include dehydration, previous heart attacks and infections of the blood stream, as stated by Healthline. Orthostatic hypotension occurs when a person transitions from sitting or lying down to standing, which often causes a brief period of dizziness. Symptoms of low blood pressure may include nausea, clammy skin, depression and lightheadedness.

Labyrinthitis is an inner ear infection caused by a virus or bacteria, according to MedlinePlus. Factors that increase the risk of developing the condition include the flu, allergies, excess alcohol intake, stress and certain medications. Labyrinthitis causes the inner ear to swell, leading to symptoms such as loss of balance, ringing in the ears, hearing loss, nausea and vomiting.
