Wonderful Things: Gastric Band

We’ve all seen those celebrities who’ve been household names for decades, who appear to be comfortable in their non- size-zero bodies. Then, lo and behold, one day, they appear with new sleek, svelte figures.

 How do they do it? Simple: a bit of prosthetic surgery and hey presto, goodbye spare tyre! I am of course, talking about gastric banding which has been in use since the mid 1980s.

A gastric band helps reduce the amount of food you eat. It simply acts like a belt around the top portion of your stomach, creating a small pouch. It restricts the amount of food that can fit into your stomach, meaning that you feel full after eating a small amount of food, resulting in weight loss.

According to The British Obesity Surgery Patient Association, on average, people lose between 50–65% of their excess weight in the two years after placement of a gastric band. Long before they reach that stage, they start to feel the benefits, especially if they also have any of the obesity–related diseases such as diabetes, heart disease or high blood pressure. They also have a much greater capacity for physical activity and more self–confidence; not like this gentleman in the public health poster below!

Having a gastric band is regarded as major surgery as patients undergo a general anesthetic. This presents some very real risks, side-effects and complications. Each operation costs the NHS around £8,000, but only those who fit specific criteria qualify to receive the surgery.

Is gastric banding an easy way to lose weight without having to diet or exercise as much? 

Would knowing someone who has had a gastric band change your perception/opinion of them? 

Is obesity a problem that humans inflict on themselves?

Should the NHS (and taxpayers) pay for gastric band surgery for very obese patients? What about if someone just wants to lose a few pounds?

Films, films galore!

When running a classroom discussion, it’s important to kick off with a starter that is engaging as well as informative, something that can help your students form an opinion on the issue and give them some knowledge to bring to the discussion.

Stimulus materials can be anything from relevant objects, news clippings, films, even witty songs. Planning a discussion around nanotechnology? Show your students this great new Punk Science film – Nanotechnology song!  And in Healthy Living, Punk Science explore the neurotransmitters that make us happy (and raise questions about fair testing!)

And if you want to get a few ideas for making your science pop, check out How to Punk your science… Having perfectly messy, artfully tousled hair is not a prerequisite.

Finally, we invited a group of scientists to try out our Mystery Boxes activity- see what they thought about it in this film.
