Dizziness and regurgitation in patients may be caused by the following aspects:1. If patients stay in the air-conditioned environment for a long time, it will lead to cooling of the spleen and stomach, which will lead to cooling of the cerebral blood vessels, and spasms and contractions of the cerebral blood vessels, which will lead to dizziness and regurgitation in patients.2. If patients have high blood pressure and cerebral arteriosclerosis, the lack of cerebral blood supply will stimulate the patient’s sympathetic nerves when the patient’s blood pressure fluctuates to a higher level, causing symptoms of dizziness and regurgitation. If the patient has high blood pressure or cerebral arteriosclerosis, the insufficient blood supply to the brain will stimulate the sympathetic nerves of the patient and cause dizziness and regurgitation, which can be clarified by blood pressure measurement and transcranial Doppler examination.3. When the patient suffers from acute cerebrovascular disease, the symptoms of dizziness and regurgitation will also appear, for example, the patient suffers from infarction of cerebellum and brainstem, which, in addition to the symptom of neurological deficits, can also play a stimulating effect on the sympathetic nerves of the patient, which can cause regurgitation, or even nausea and vomiting. 4, vestibular organ diseases, such as Meniere’s disease, vestibular neuronitis, can lead to severe dizziness, accompanied by nausea, regurgitation symptoms, and in severe cases, it will also be accompanied by cold sweating, tinnitus, ear boring symptoms.
