Dear Doctor,
About 5 years ago I had a clot in my ankle. since then I have been on warfarin to keep the blood thin. Can you tell me is there any reason whey I shouldn't start diving. I am 68 and it is something I have always wanted to do.

My dosage is about 7mg. I have not had any ongoing problems with this since I started taking the warfarin.

Thanks for the email.

Diving on warfarin does carry one or two risks. Obviously your blood will be thinned and so any cuts on coral, sharp pointy bits of wrecks etc. will bleed for longer and may get infected more easily. There is also a risk of DCI being made worse, if there is a bleeding component to it (eg. if you are unlucky enough to get a spinal hit).

That said, many divers who are well controlled on warfarin (with stable INR's) do dive safely. You'll need to tick a couple of boxes on the self-declaration form and so you may need to have a medical cert - check with the dive operator where you're going to dive and if you need a medical and you're in the London area, it's 0207 806 4028 for an appointment.
