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 hydration status & electrolyte balance of the body.
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 foods
2. Drink lots of water to maintain adequate hydration
3. Avoid fast food.
4. Avoid smoking & alcohol.
5. Keep away stress..think positive.
6. Exercise regularly & practice
meditation.
Wishing your brother a Good Health.
Thanks & take care.
