What Causes Brief Lightheadedness?
It could be transient.
Detailed Answer:
Hi,
Welcome to HCM,
I have read your query and understand the concern regarding lightheaded.
Usually, symptoms like this is transient and do not cause problems. Mostly it could be due to variety of causes like vasovagal or stress or anxiety. But there is no need to worry if this has happened for the first time since the likely cause could be work related stress in your case, the first possibility comes in mind after going through your query.
Let me know if you have any other symptoms apart from feeling lightheaded?
Since you are feeling better now we need not address it. Until then take proper hydration (drink lot of water) and electrolyte balance (fruit juices) with some symptomatic antihistamines treatment like cinnarizine 25 mg (stugeron). Do not panic.
But in case, if the lightheaded persists even after symptomatic treatment, I would suggest you to see a doctor at the earliest and get evaluated further.
Hope this helps.
Regards,
Dr.Sandip Kabra
