What is Therapeutic Venesection?

Therapeutic venesection, sometimes called therapeutic phlebotomy, is a clinical procedure that involves removing a measured amount of blood from a vein. The process is similar to blood donation, however it is performed for medical reasons rather than for donation purposes.

By reducing circulating red blood cells or iron stores, venesection can form part of the management plan for certain medical conditions where blood parameters have become elevated.

Why Might Someone Need a Venesection?

Venesection may be recommended when blood tests show elevated red blood cell levels, increased haematocrit (HCT), excessive iron stores, or other abnormalities that require ongoing clinical management.

Raised Haematocrit (HCT)

Haematocrit represents the percentage of your blood made up of red blood cells. Elevated haematocrit can increase blood viscosity and is a common reason patients seek therapeutic venesection.

TRT-Related Erythrocytosis

Testosterone Replacement Therapy (TRT) can increase red blood cell production in some individuals. Where haematocrit rises beyond acceptable levels, venesection may be advised as part of a wider monitoring strategy.

Polycythaemia

Patients diagnosed with polycythaemia or secondary erythrocytosis may require periodic venesection to help manage elevated red blood cell levels under the guidance of their healthcare team.

Haemochromatosis

In hereditary haemochromatosis and other iron overload conditions, venesection can be used to help reduce excess iron stored within the body.

Venesection for TRT Patients

Many patients undergoing Testosterone Replacement Therapy monitor their haematocrit and haemoglobin levels as part of routine care. Testosterone can stimulate red blood cell production, leading to elevated haematocrit in some individuals.

If your TRT provider, doctor, or healthcare professional has advised venesection due to elevated haematocrit, we strongly recommend bringing recent blood test evidence to your appointment.

Please Note: Venesection should not be viewed as a substitute for proper TRT monitoring. If haematocrit remains elevated, your prescribing clinician may also need to review dosing, injection frequency, hydration status, sleep apnoea risk factors, smoking status, and other contributing causes.

How to Prepare for Your Appointment

Stay Well Hydrated

Please drink plenty of water before your appointment. Good hydration can make the procedure easier and may reduce the risk of feeling faint afterwards.

Eat Before Attending

We recommend having a meal or substantial snack before your appointment. Please do not attend on an empty stomach.

Bring Recent Blood Results

If your venesection is being performed due to a raised haematocrit, particularly while on TRT, blood test results from within the last month are required.

Allow Time to Recover

Avoid intense exercise, heavy lifting, alcohol consumption, sauna use, or strenuous activity immediately after the procedure.

Who Should Seek Medical Advice First?

Venesection may not be suitable for everyone. If you have a history of severe fainting, anaemia, significant cardiovascular disease, active infection, uncontrolled medical conditions, or are unsure whether venesection is appropriate for you, please seek advice from your GP, consultant, TRT provider, or another suitably qualified healthcare professional before booking.
