Hi,
There can be various reasons for your episodes of dizziness and
lightheadedness. It can be due to disorders of brain (infections or swelling), heart disorders (usually arrhythmia - rhythm disturbances) or disorders of ear (benign positional vertigo, infections of ear - labyrinthitis, swelling of the nerves- neuritis). Even sometimes
cervical spondylosis (neck problems) can also cause such symptoms. Besides this anemia, hypoglycemia (
low blood sugar), hypotension (low blood pressure), prolonged fasting, lack of sleep,
electrolyte imbalance (abnormal salts in the body).
I feel that, first of all, you can take care of your lifestyle, take good balanced diet, have proper sleep and maintain proper posture. But along with that do go for some investigations like
complete blood count, TSH, electrolytes, ECG and MRI (brain). This will help us to make exact diagnosis and then plan proper treatment.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Milinda Gupta, Internal Medicine Specialist
