You're asking a medical question of a random Internet forum, IMO that's not a good start. Particularly since you don't live in the US so it's likely that simply asking a doctor a question isn't going to financially destroy you and your family.
If any sort of worrisome medical condition just "randomly" shows up for no apparent reason, that's reason to go check with a professional.
Ya know that's irrelevant to the point being made, right?
Whatever you may personally think about those products they're very profitable now.
