Hello. Welcome to HCM and thank you for your question. I carefully read your query.
Lightheadedness, and especially loss of equilibrium, has some origins, but I would recommend to confirm or exclude only two of them. First, it can come from the heart conduction system disturbances, and usually are accompanied with darkening of the vision, and episodes of near-
fainting or clear-cut fainting. I recommen you to do an EKG and, then, if judged appropriate by your consulting cardiologist, a 24-hour rhythm monitor registration. Second, this is a common symptom of
inner ear disturbances, where is located a small organ responsible for balance. I recommend you to consult an otorhinolaringologist (the ENT doctor) about this or first try a course with betaserc 24 mg x 2 tb/d for 10 days. This drug helps also in differential diagnosis, i.e. if the episodes do not occur while under this drug, then we can confirm, with highest probability, that these epsodes' origin is in the inner ear.
As about the
high blood pressure, the figures you provides are within normal range, as worldwide population standard normal blood pressure figures are 100-139/60-89 mmHg. Therefore, my opinion is that there is nothing to worry about regarding this.
Wish you a good health. I hope I was helpful.
Best regards,
Dr. Meriton
