Could be due to blood pressure changes

Detailed Answer:
Hello XXXXXXX

Thanks for posting on XXXXXXX

It seems to me you have supplied limited information as regarding your age and medical history. I am afraid that specific causes of lightheadedness mostly depend on age, underlying medical problems and nature of occupation. If you are suffering from dizzy spells or vertigo that could be related to high blood pressure or postural orthostatic hypotension. Light-headedness can be simply (and most commonly) an indication of a temporary shortage of blood or oxygen to the brain due to a drop in blood pressure, rapid dehydration from vomiting, diarrhea, or fever, or from playing a wind instrument. Other causes are low blood sugar, hyperventilation, panic attacks, and anaemia. It can also be a symptom of many other conditions, some of them serious, such as heart problems (including abnormal heart rhythm or heart attack), psychosocial problems, respiratory problems such as pulmonary embolism, and also stroke, bleeding, and shock.
Well just listing possible causes given that you did not provide any other useful background information.
Treatment will depend on underlying cause. If this persist after a couple of days of bed rest, then you will need to seek medical assistance.

Hope this helps and wish you the best.
