Dizziness and nausea may result from an injury or a health-related illness. According to Mayoclinic.com, dizziness and nausea can be caused by a concussion. People who suffer from vertigo or go into anaphylactic shock can also experience dizziness and nausea. If symptoms of dizziness and nausea do not stop or continue to get worse, contact a health-care provider.
Concussion
A blow to the head can cause the brain to shift violently inside the skull cavity often causing damage. When the brain becomes damaged due to a sudden impact or injury, swelling or bleeding can occur often leading to a concussion. According to the Mayoclinic.com, symptoms of a concussion include dizziness, nausea, feeling faint, fatigue and ringing in the ear. Other symptoms include sensitivity to light and noise, problems concentrating, memory problems and irritability. People who play sports or who are involved in any kind of rigorous activity can be more at risk for developing a concussion. The severity of a concussion can vary from mild to severe and people who suffer from them don’t always lose consciousness. The best treatment for a concussion is plenty of rest. Pain relievers may be taken to alleviate headaches.
Benign Positional Vertigo
Benign positional vertigo is a condition that exists when a person suddenly develops a sensation of spinning during normal movement of the head. It is one of the most common causes of vertigo. Benign positional vertigo occurs when a tiny piece of bone-like calcium breaks loose and floats within the canal of the inner ear, according to the University of Maryland Medical Center. This sends the brain confusing signals about the body's position, causing dizziness. Other symptoms include nausea and visual disturbances. The most effective treatment for benign positional vertigo is surgery in which the tiny bone fragment that is floating in the ear is removed. Medicines such as anticholinergic and antihistamines may be prescribed, but seldom prove very effective.
Anaphylaxis
People experience anaphylaxis when they come into contact with an allergen that severely irritates the body’s immune system. A bee sting, allergy to a specific food or medicine can cause anaphylaxis. FamilyDoctor.org states that foods such as eggs, peanut butter, shellfish or fruits can all cause an allergic reaction resulting in anaphylaxis. According to the Mayoclinic.com, when the body’s immune system senses a foreign invader--the allergen--it overreacts to the event and causes a high amount of various chemicals to be dumped into your system. These chemicals can cause the body to go into to shock, blood pressure to drop and the airways to constrict, making the condition life-threatening. Symptoms of anaphylactic shock include skin reactions--hives or rash--trouble breathing, wheezing, dizziness, nausea and fainting. If someone goes into anaphylactic shock, immediate medical attention is vital.
