Dizziness, mild nausea. What's going on?

If the primary disease is dizziness, it may cause sympathetic excitation due to dizziness, resulting in increased heart rate, nausea and vomiting, and even incontinence, mainly including Meniere syndrome, hypertension, cervical spondylosis, colds, sleep disorders, etc. If nausea or vomiting causes increased intra-abdominal pressure, it may also cause reflexive head discomfort, such as dizziness, headache, dizziness, transient amaurosis, visual rotation, etc. No matter what the cause is, you can first choose to lie still and rest. If the symptoms do not improve, you can use some painkillers. If you still do not improve, you must go to the neurology department or gastroenterology department of the hospital for diagnosis and treatment.
