Hi my dear, I am glad to know that your vital were fine. Apart oscillations in blood pressure, there might be other causes to feeling light headed: - oscillations in blood sugar (especially if you skip your meal/breakfast) - being dehydrated (not enough water consumptions, as you teach you need more water to wet-up your mouth throat dried from keep talking) - stress/work overload - spondyloarthrosis (arthritis of the spinal cord of neck level) - hormonal disbalance at your age due to pre/menopause I suggest to: - keep monitoring your blood pressure and sugar, record the results for further evaluation - although your vital were fine, you should do an EKG, cardiac echo and holter monitoring to exclude heart problems - do an abdominal ultrasound - run urine analysis, complete blood profile and measure electrolytes and hormonal levels - do X-ray of neck and chest Based on lab results, further treatment is prescribed specifically. All the best! Dr.Alba
