Get rid of the ads at the top. You have about 1.5 seconds to make an impression on the reader - and the theme is confusing as well as the title (perhaps not to medical folk) but regardless - you need to "invite" the reader to become engaged in your content. The ads put me off straight away sorry
i like the template, but you have free domain, buy [.com] domain, reg to Google adsense, and you have $$$$ from your blog
