What causes dizziness, lightheadedness and slight nausea?
Yes, you should see a doctor
Hello and Welcome
I appreciate your concern
Dizziness, palpitations and nausea can be related to neurologic , metabolic or cardiac causes. Blood sugar, B.P and neurological exam should be done, primarily. If there is hypotension or shortness of breath then an EKG should be done primarily to rule out a cardiac cause e.g arrhythmias, heart block etc. Sensations of dizziness and vertigo are often confused and should be elicited clearly as dizziness requires a cardiac workup whereas vertigo is treated more on neurological lines. If all the above are normal then betahistine dihydrochloride ( serc 16 mg ) and metoclopramide can be prescribed for the dizziness and nausea. In short, it would be preferable to see a doctor.
Wishing you best of health
