Are you on diabetes or blood pressure medication? If so do you take a “water” pill (diuretic)? I am a coach at an endocrinologist office. When a dieter with blood pressure meds or diabetes meds start experiencing dizziness we have to adjust their medications and that solves the problem. You need to consult with your coach or your primary care Dr if you do. Your dr or the clinic dr are the only ones who can make those changes.
