Hello and welcome to Health Check from the BBC.
I'm Claudia Hammond,
here for the next half an hour with the latest stories on health from around the world.
And my guest today is BBC health reporter Philippa Roxby.
Hello.
What do you have for us today?
Hi.
Yeah, we're going to be looking at the impact of weight loss, drugs on alcohol addiction.
And did you know that your heart actually responds to sweet things?
It's really intriguing, this.
I'm looking forward to that one.
And we'll hear from a clinic
in Uganda which tells me it is already having to turn away patients who need HIV medication due
to the fruit on aid from the US
and we'll be asking where you start
if you're trying to rebuild a health system destroyed by war.
Before that, Philippa, we wanted to start with what some are describing as a global oxygen crisis.
So medical oxygen can save your life if you're seriously ill,
keep you alive if you're having surgery,
and make life more bearable if you have a chronic respiratory problem.
