Smitha Mundasad asks whether we will see waves of Covid – with infections going up and down and then up and down again - forever more. We speak to Elliot whose life has been transformed after a single shot of gene therapy to treat the inherited blood disorder haemophilia B. And Dr Margaret McCartney discusses the accidental discovery of Viagra and how sometimes researchers find new, surprising uses for old medicines.

Rashes, a runny nose and weird poos are all common in babies. Parents are sometimes told these symptoms mean their baby is allergic to cows milk and are prescribed low allergy formula or advised to avoid dairy if they are breastfeeding. Marijke Peters cut dairy out of her diet to try and help the gut problems her new baby Eva was having - but it made no difference and she's still trying to find out why she has blood in her poo.

Dr Robert Boyle sees babies with allergies in his clinic at St Mary's hospital in London. Those with a cows' milk protein allergy can safely drink low-allergy formula milk - but Dr Boyle thinks that more than the expected 1% of babies are being diagnosed with the allergy. So he looked at the number of prescriptions for these specialised formula milks dispensed in the UK, Norway and Australia. In the UK he says that ten times the number you'd expect to see are prescribed.

Professor Paula Moynihan who's Director of Food and Health at the University of Adelaide says these formula milks could pose a risk to children's teeth because they contain different sugars than the type found in milk - which bacteria in the mouth can feed on, making it more acidic and potentially damaging the teeth. She says that any babies given the dairy-free formulas should have their teeth brushed twice a day with a fluoride toothpaste and start seeing a dentist as soon as the first tooth appears.

Dr Margaret McCartney explains how long-Covid patients are going to extraordinary lengths to try unproven treatments in the hope that they will alleviate their symptoms. We hear how an investigation by the British Medical Journal uncovered how a special type of blood filtering called apheresis and hyperbaric oxygen therapy - costing thousands of pounds - are offered to long-Covid patients in European clinics but there is no evidence that they will help them. Margaret recommends instead signing up for NHS trials investigating potential treatments in a regulated way.

Gout is incredibly painful but many adults diagnosed with the condition aren't taking the recommended medication a year after they were told they had it. Dr Mark Russell from Kings College hospital in London found that only a third of people with gout were taking medication to help lower urate levels in their blood which can turn into crystals in the joints and organs like the kidneys if it is too high.

What do you think bendy joints has to do with the way the brain works? Well you may be in for surprise. Scientists have found a connection with autism, attention deficit and Tourettes. So what does this tell us about how our brain and body work? We’re asking whether we’re stuck with monkeypox forever now or do we still have the chance to stop it spreading? And has the pandemic left a permanent scar on children’s activity levels.

Does medicine have a language problem? We speak to Rachel who was made to feel like a 'naughty schoolgirl' by the terminology used around the birth of her child. We’ll find out how deep-seated blaming and belittling language in healthcare is, and why. We get sticky and sweaty discussing the dangers of heatwaves to the human body. And we take the confusion out of 'chemo brain' or cancer-related cognitive impairment, and explore why we rarely talk about it and how this is now changing.

Aaaaaaaaa-choo! If you have hay fever then you know that it can be a right pain in the… nose. This week Inside Health presents a complete guide to hay fever. Are we enduring the worst hay fever season? When was the disgustingly-named “summer catarrh” first identified as a medical condition? And what can we safely plant in the garden without setting off our symptoms? GP Navjoyt Ladher and immunologist Danny Altmann join James Gallagher in the park to talk causes and treatments, and to find out how close we are to having a cure.

This week James Gallagher finds out if the Power of the Dog is true. No not the movie, but the claim that dogs can make us live longer. He’s also doing press ups in the studio to see if small amounts of muscle building exercise can help boost our health no matter how old we are. Then, inspired by the last episode on long Covid, James goes in search of the lost art of convalescence.

It’s a long Covid reunion on Inside Health. We first met Jo, Neil and John in February 2021 when they were 12 months into the condition.

Another year on, we catch up with them to see if they are any closer to making a full recovery. We explore how a virus can cause such prolonged symptoms, with Dr David Strain from the NHS Long Covid Taskforce, and see if we are any closer to treating long Covid.

We get to the bottom of a medical mystery – what causes multiple sclerosis? A series of studies have compellingly pointed the finger at the virus behind glandular fever. We see if they stack up and assess what it means for the future of preventing and treating MS. Then nearly two years since the World Health Organization described Covid as a pandemic, James chats to Dr Maria van Kerkhove, who is the WHO's technical lead for its response to Covid, about the successes and failures of the past two years and where we’re all heading next?

How often do we need a smear test? It’s become controversial now as a new test means women and people with a cervix need checking less often. But in the future the answer might be only once a lifetime!

We hunt for the special blood that's in high demand, yet in short supply, for people with sickle cell disease. And could the disruption from the Covid pandemic be setting the stage for a large outbreak of measles?

James meets a record breaking doctor who is analysing DNA so quickly it is transforming treatment in intensive care and from one of his patients, Matthew, who discovered he needed a new heart. Then James has a disgusting confession as we discuss losing weight by getting more sleep. And can we get better therapies for all of us by copying the revolutionary trial that transformed the pandemic.?
