Hello Practo user ,
according to your query it can be stated that you might be on the lower side of some of the vital vitamins , proteins or minerals (reason can be life style related diet)for that you need to get yourself a complete body checkup (vitB12,CBC etc..) and consult a doctor nearby your place(Ayurvedic or Allopathic your choice).
This dizziness with generalised weakness problem of yours can be due to many reasons like workload ,
vitamin deficiency which need not taken lightly.
I would personally suggest you to visit a Physician as soon as possible to avoid further deteoration in your health condition.Feel free to contact for further assistance.
Regards,
