Common causes of dizziness and vomiting are otolithiasis, Meniere’s disease, posterior circulation ischemia, anemia, and colds. Otolithiasis, also known as benign paroxysmal positional vertigo, is caused by the dislodgement and displacement of an otolith in the semicircular canal of the inner ear. It manifests as severe vertigo that lasts for a few seconds, accompanied by nausea, vomiting, panic, and other discomforts. Ménière’s disease is mostly caused by edema of the labyrinthine labyrinth of the inner ear membrane, and the dizziness lasts for a longer period of time, and may be accompanied by a feeling of stuffiness in the ear, nausea, and vomiting. Posterior circulation ischemia refers to the narrowing of the vertebral basilar artery, resulting in insufficient blood supply to the brainstem and cerebellum, which are closely related to the balance function of the body and are prone to dizziness and vomiting after ischemia. In addition, some systemic diseases, such as anemia, colds, and fluctuations in blood pressure, may also lead to symptoms of dizziness and vomiting. There are many causes of dizziness and vomiting, so it is recommended that patients seek timely medical attention to identify the cause and target treatment under the guidance of the doctor.
