<bot>: Hello dear, The symptoms as mentioned in your post can be due to:1. Any pathology in the Vestibular apparatus in the inner ear, which maintains posture & balance.2. Any fluctuation in the blood pressure or blood sugar levels.3. Inadequate HY Chat Doctor. 4. Deficiencies of certain nutrients like Iron, vitamin B 12, Folic acid, etc. which helps in blood formation & nerve conduction.5. Hormonal & metabolic causes.6. Stress, inadequate sleep, etc. So, kindly consult your Physician and discuss regarding this. Investigations like complete blood count, estimation of blood pressure & blood sugar levels, CT scan of brain will be helpful to rule out any pathological cause for the symptoms. And it is also needed that certain precautions regarding diet & lifestyle should be taken, such as:1. Take soft, plain, non-spicy foods2.
