a medical spa trend

When was the last time you got a full medical check done? This year, last year or earlier than that? I got a brochure of a medical facility that was advertising it's plans for health checks and I was surprised to see several add ons such a spa treatments and many optional items such as checks for colon etc, including a spa treatment with things like a colon cleanse to really improve the way your body handles waste. I do know that many people use it as a way to lose weight but I wonder how effective it really would be or how long term. The trend of making medical checks more glamorous and therefore combining them with spas is getting rather popular.
