I’m interested in taking a diving course. I have factor V Leiden in a heterozygous form. Is this a characteristic that prevents me from diving?

Under conditions of significant decompression stress with large amounts of circulating gas bubbles (dehydration, stress, exercise, debilitation), resistance to decompression stress may be reduced and haematological adverse events may be exacerbated, with an increased risk of platelet aggregation, leukocyte activation and triggering of the coagulation cascade. Your clinical situation is decisive and the haematologist’s opinion on the intrinsic risk of thrombosis, in normal life and under conditions of physical exertion, is important. If the thrombotic risk in normal life is considered low, diving may be possible, respecting low bubble-producing dive profiles, e.g. not exceeding 30m and typical recreational diving times, and using enriched mixtures (Nitrox) to further reduce the risk of decompression and inert gas (nitrogen) accumulation. A ‘Fit-To-Dive’ certificate issued by a diving and hyperbaric medicine specialist is recommended for diving activities.[/vc_column_text][/vc_column][/vc_row]
