Common Causes of Dizziness and Vomiting
Dizziness and vomiting are symptoms that can arise from a wide range of medical conditions. These symptoms often occur together and can be caused by problems in the nervous system, inner ear, cardiovascular system, metabolism, medications, infections, and psychological factors 1710.
Neurological and Central Causes
Central nervous system disorders are a significant cause of dizziness and vomiting. Conditions such as posterior stroke, vertebrobasilar insufficiency, and vertebral artery dissection can present with these symptoms, often alongside other neurological signs like ataxia, double vision, or weakness 2567+1 MORE. Older age, a history of stroke, diabetes, and the presence of ataxia or focal neurological symptoms increase the likelihood of a central neurological cause .
Peripheral Vestibular Disorders
Peripheral vestibular disorders, such as benign paroxysmal positional vertigo (BPPV), labyrinthitis, and vestibular neuritis, are among the most common causes of dizziness and vertigo. These conditions often lead to spinning sensations, unsteadiness, nausea, and sometimes vomiting 178. BPPV, in particular, is a frequent cause in the elderly .
Cardiovascular and Metabolic Factors
Cardiological issues, such as arrhythmias or low blood pressure, and metabolic disturbances, like low blood sugar, can also cause dizziness and vomiting. These are often accompanied by other symptoms such as fainting or weakness .
Medication Side Effects
Certain medications, especially those affecting the nervous system, can cause dizziness and vomiting as side effects. For example, the dopamine agonist ropinirole, used in Parkinson’s disease, has been associated with these symptoms due to its action on the brain’s vomiting center 37.
Infections and Foodborne Illness
Gastrointestinal infections and foodborne illnesses are common causes of dizziness and vomiting, especially when accompanied by nausea, diarrhea, and stomach pain. Outbreaks in settings like schools are often linked to contaminated food, such as meat products, and may be caused by bacteria like Salmonella .
Postoperative and Other Medical Conditions
Dizziness and vomiting are also common after surgeries, particularly abdominal procedures under general anesthesia. These symptoms can be managed and reduced with proper patient education and preventive strategies .
Psychological Causes
Psychological factors, including anxiety, depression, and panic disorders, can also manifest as dizziness and sometimes vomiting, especially when no physical cause is found 17.
Conclusion
Dizziness and vomiting are symptoms with many possible causes, ranging from benign inner ear problems and medication side effects to serious neurological or cardiovascular conditions, infections, and psychological issues. Accurate diagnosis relies on a careful medical history, physical examination, and sometimes specialized tests to identify the underlying cause and guide effective treatment 1710.
