Can I still go diving with high cholesterol?

Having high cholesterol is a major risk factor for having a heart attack or a stroke, both of which could be fatal underwater. For this reason it is important to consider high cholesterol levels as part of your overall cardiovascular health when diving.

If you have been diagnosed with high cholesterol on routine blood tests you may be controlling it with dietary measures, or you may be taking medication.

If you have been started on medication to lower cholesterol after a heart attack or stroke, please see the relevant ‘Can I dive with..?’ sections for more information.

Cardiovascular risk

Your cardiovascular risk (your risk of heart attack or stroke) is affected by many factors. These include obesity (measured using body mass index – BMI), your smoking status, blood pressure, cholesterol levels, whether you are diabetic, and your family history.

What do I need to do before diving?

You will need to submit your self declaration medical form and discuss your medical history with one of our doctors during a telephone consultation.

Our doctor may ask for further information. This normally includes an assessment of your other cardiovascular risk factors. If investigations are required (e.g. blood tests), your GP should be able to arrange these, as your cardiovascular health is not just important for diving.

Our doctor may sign your certificate remotely, or may ask you to attend for a Sports Diver Medical.
