Weight loss

If you're getting dizzy, I'd suggest you talk with your doctor. Another option would be to look up, or ask your pharmacist, whether dizziness is a known side effect of any of your medications. If so, discuss that with your doctor.

Sometimes, when people try to lose weight, they try to lose weight too fast for their current body size, cut calories too far, and that can make some people weak or dizzy. I don't know whether that could be true for you, or not. Sometimes seriously sub-ideal nutrition can do the same thing, for some people. People with particular health conditions can have dizziness episodes with a change in eating habits - that's another doctor question.

Yes, call your medical provider. Also read the pharmacy papers for drug side effects, and if possible keep a written log of blood pressure readings you take at home or in a pharmacy blood pressure kiosk -- you can give your medical provider the log. Good luck!
