Hello Michele, The symptoms as mentioned in your post can be due to: 1. Any pathology in the vestibular apparatus in inner ear (it is associated with maintenance of body posture & balance) & Cerebro-pontine angle 2. Any fluctuation in blood pressure levels such as Hypotension 3. Decrease in blood sugar levels (Hypoglycemia) 4. Deficiency of certain nutrients like Iron, Vitamin B 12, Calcium, etc. which also interferes with blood formation & nerve conduction. 5. Long term use of certain medications. Investigations like complete blood count, estimation of blood pressure and blood sugar levels will be helpful in clinching the diagnosis. So, it will be better to consult an ENT specialist & get a proper physical examination done. Based on that appropriate management steps could be taken. Meanwhile, maintain adequate hydration, take a healthy balanced diet & avoid stress. Also, make sure that you do not get up or bend down suddenly. Take some time, it prevents peripheral accumulation of blood & reduces the symptoms of dizziness & light-headedness. Wishing you a good health. Thanks & take care.
