Hi,
There can be various reasons for
dizziness. It can be due to anemia,
low blood sugar, prolonged fasting or vitamin deficiencies. Even stress and anxiety can also lead to such symptoms.
Besides it can be due to problems related to ear(infections,swelling , neuritis or benign positional vertigo), neck(
cervical disc disease), heart(
arrhythmia)or brain(infection or swelling in the brain.
So I feel that first of all focus on his diet.Eat plenty of fruits and vegetable, and drink plenty of water.
Maintain proper posture especially while sleeping or working on computer.Regularly monitor your bp.Relax.Let him have a good night's sleep.
Also if still your symptoms persist then go for some investigations like
complete blood count,FBS,tsh, xray neck,ECG and MRI brain.This will give you a proper diagnosis and then treatment can be planned.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr. Milinda Gupta
