Thai health insurance is not regulated like in Switzerland: Premiums go up considerably with age, and sometimes also after making any claims.
Moreover, any new policy will likely exclude any pre-existing conditions, have $ limits on annual coverage, and lifetime caps on amounts reimbursed per condition.
Anyway, I hope that the cost of insurance in Switzerland isn't the only reason to consider moving to Thailand... Living here is very different from taking a holiday here.
