What department should I go to for dizziness, nausea and vomiting in pregnancy?

You should consult the appropriate department according to the different symptoms. For example.
If only dizziness with nausea and vomiting is present and the symptoms are mild, they can be observed at home by themselves first.
If there is tinnitus, ear swelling, hearing loss, blurred vision, etc., the patient should consult the otorhinolaryngology department because of the lesions in the vestibular organs.
(b) Patients with oedema, hypertension and convulsions in mid- to late-pregnancy should be alerted to hypertensive disorders of pregnancy and may be seen in the emergency obstetrics department.
If vomiting is more violent and there is impaired consciousness or even coma, the patient should be sent to the emergency clinic immediately.
