Many causes can lead to a sudden urge to vomit and dizziness and general weakness, which should be analyzed in relation to the triggers and underlying diseases that caused the patient’s onset. For example, elevated blood pressure can lead to these problems. Patients with coronary artery disease may also experience sudden vomiting, dizziness and general weakness when they have arrhythmias that cause cardiac insufficiency of blood supply to the brain, or patients with cerebral arteriosclerosis or cerebral vascular stenosis may experience severe dizziness, vomiting and general weakness when they have vasospasm. There are also peripheral vertigo, such as Meniere’s disease, vestibular paroxysm, vestibular neuronitis, etc., which can cause such symptoms in patients. Therefore, when patients have these problems, it is recommended that they visit a hospital for examination and treatment in a timely manner.
