The rise of antibiotic resistance means that we need alternatives to fight infections - and some healthcare professionals are turning to maggot therapy to help clean up wounds. They might be treating people living with diabetes who can experience a loss of sensation in their feet because of high blood sugar levels. Damage to their blood vessels can also slow down healing. Melanie Rix Taylor from Swansea has type 1 diabetes and had a quarter of her foot amputated because of an infection. When the skin around the wound started to die she was offered maggot therapy. After just a few days the larvae placed on her foot in a small bag - a bit like a teabag - digested the dead skin, helping to promote healing. Her Podiatrist at Morriston hospital Ros Thomas explains how she's used maggots hundreds of times, with great success.

The larvae of the greenbottle fly species Lucilia sericata are supplied to the NHS on prescription with an average cost of £200-£300 from BioMonde in Bridgend. James visits their fly room with entomologist Micah Flores, helping him to collect some of the fly eggs which are then thoroughly cleaned and prepared so they can then be used on patients. As well as consuming dead tissue, the larvae also produce anti-microbial secretions and help to promote healing. Professor Yamni Nigam from Swansea University - who's advised television programmes like Casualty about storylines on maggot therapy - is a big fan of the creatures which have a long history of being medically useful, long before scientists found the scientific proof to support their use. She wants to help people to get over their initial disgust so that they can be used more widely, instead of as a last resort.

Covid and other bugs have ripped through the Inside Health team, so we find out why everyone seems to be getting sick at the moment and if we will be facing a torrent of infections for months or even years to come. We see how easy it is to buy antibiotics online and why scientists are worried about it. And can ketamine and its mind-altering powers can help free people from addiction to alcohol?

It’s January. Christmas is a distant memory and nobody feels much like getting off the sofa, but luckily this episode can help. James Gallagher is on a mission to find out what is the least amount of exercise you can do to still stay healthy. James goes on a Ramblers wellbeing walk, uses a treadmill for the first time and takes a hot bath all to find out how lazy he can be. His guide Dr Zoe Saynor at University of Portsmouth explains this is the question everyone asks and offers simple tips about how little you can do.

James is in South Wales where he's wired up and locked inside a cryo-lab to discover the impact of cold on the human body. A temperature of 10C seems pretty mild doesn’t it - yet James is shocked at the profound stress it puts on his body. Today we discover why cold is a killer and what you can do about it if you’re struggling to heat your home.

Do you want to see your GP records at the touch of a button? That’s the plan in England, but doctors warn us freely opening them up to everyone is not safe. And we’ll explore a study that’s transforming our understanding of how cancers develop and bring clarity to the confusion around antidepressants after a study showed low serotonin levels were not the cause of depression.

Can you imagine moving out of the family home and watching your daughter grow up from a distance, all to avoid the threat of Covid? That’s the decision Shannon has taken because the drugs she takes for her lupus leave her immune system weak and vulnerable. She tells us what it’s been like shielding for 951 days (and counting) and we explore whether there are any solutions. Then we see why childhood vaccination rates have been falling for a decade and whether you should follow the health secretary’s example and share your antibiotics.

I think I might’ve dodged Covid. Like many others, I’m fully vaccinated but have never tested positive despite having had plenty of opportunities to catch it. I used public transport to get to work during the lockdowns and was exposed to the virus when my son came down with it. So what’s going on? Armed with my covid antibody test results, I ask immunologist Prof Mala Maini to clear up the confusion. And a new scale to determine skin colour which could improve how certain health problems are diagnosed and treated.

Maybe listen to this one BEFORE you eat… James is off to meet the sewage scientists trying to stop the next pandemic. He meets the teams that were monitoring 80% of people’s faeces during Covid-19 and finds out how sewage led to hundreds of thousands of children having an emergency polio vaccine. James needs to collect a sample at a water treatment works and then head to the laboratory… just be glad you can’t smell a podcast.

What do sweeteners do to our bodies? We force feed James cups of sweetened tea and find out with nutrition scientist Dr Sarah Berry from King’s College London. We then tackle something stronger - alcohol. Can a new supplement reduce the amount of alcohol getting into the body? And Rohin Francis gets frustrated at the shonky claims being made by health podcasts (not this one, of course, you’re totally in the right place).

Should friends and family be trained to give potent medications to those dying at home to relieve their symptoms?

We often say that we’d like to die peacefully at home when the inevitable happens. Yet people can be left in pain for hours waiting for a doctor or nurse to be free to visit and administer the medicines that ease our symptoms in our final days. James Gallagher speaks to Mark, who was trained to administer medicines to his mother to help keep her comfortable at the end of her life, and to palliative care doctor Marlise Poolman who is pioneering the programme across North Wales.
