Nausea and metformin: Metformin can cause lactic acidosis, a condition which can present as nausea. One also gets nausea with metformin if one is not taking it with protein. The other medications, lisinopril and hctz, (hydrochlorothiazide) a diuretic can cause dehydration, which can cause low potassium, dizziness, and nausea. See your physician and have your electrolytes checked. In the meantime, eat a banana and hydrate.
