Dizziness, nausea and vomiting may be due to motion sickness, Meniere’s disease, vestibular neuritis, and benign paroxysmal positional vertigo. Treatment needs to be based on the cause of the disease to choose different methods. 1. Motion sickness: When the organism travels by boat, airplane, elevator or ship, the vestibular end receptors in the inner ear will be stimulated. The organism will show dizziness, nausea and vomiting, and pallor. Symptoms can be relieved with the use of theobromine and scopolamine. 2. Ménière’s disease: the cause of Ménière’s disease is still unclear, and it is considered to be related to the imbalance of lymphatic uptake and endolymph production. Patients may present with vertigo, hearing loss, nausea and vomiting. It can be treated with benadryl and betahistine. 3. Vestibular neuritis: Vestibular neuritis may be caused by viral infection, bacterial infection and vascular lesions. Patients may have symptoms such as vertigo, nystagmus, nausea and vomiting. Methylprednisolone and hydrocortisone can be used to improve vestibular function. 4. Benign paroxysmal positional vertigo: It is characterized by strong rotational vertigo that occurs due to the change of head position, and may be accompanied by symptoms of autonomic dysfunction such as nausea and vomiting. The otolith can be reset by a specialized doctor to relieve the symptoms. 5. Others: Dizziness, nausea and vomiting may be caused by acoustic neuroma, high blood pressure, carbon monoxide poisoning, refractive error and so on. It is necessary to carry out targeted treatment according to the cause of the disease. It is recommended that patients with dizziness, nausea and vomiting should consult a doctor in a timely manner to identify the cause and choose appropriate measures under the guidance of the doctor. The above drugs should be taken strictly in accordance with the doctor’s instructions, and should not be used blindly, so as not to cause adverse consequences.
