Thank you for posting your query on HCM.
well it may be due to plane anxiety
only. but whatever history you give hyperthyroidism
needs to be ruled out by getting complete thyroid profile done . Aliskiren doesnt not lead to such effects but can lead to metabolic abnormalities which can give this kind of picture .
I advise you to visit a physician to get yourself thoroughly evaluated and all routine tests done to look out for the cause .
If you have any further queries feel free to ask .
Hope it answers your query.
Take care .
