You are targeting a term which looks quite competitive in the SERPs, so it is not going to be easy to rank well and will take some time.
Having a quick glance at your page it it clear that it is over-optimised as Sandip points out.
Running a quick on-page report with SEOMoz for the term gastric band hypnotherapyand your page it is clear you are **keyword stuffing with 51****occurrences **of the term on your page. You need to look at making our page more natural as over-optimization is something that has been under scrutiny of late with Google.
I would also look at your link profile for this page - running your page through opensiteexplorer.org it is clear that you have over done the use of anchor text with 7 linking root domain and 271 links containing the specific keyword anchor text - gastric band hypnotherapy.
Essentially you need to look at re-doing your on-page optimization to make it more natural. You also need to look at diversifying your link profile in terms of anchor textas it is clear too targeted at the moment.
I hope this helps Diane.
