Erythrocytosis

Erythrocytosis, often referred to as polycythaemia, is a condition characterised by an elevated level of red blood cells in the bloodstream. This increase in red blood cells can lead to thicker blood, which may impede its flow through blood vessels and organs. While not everyone with erythrocytosis will experience symptoms, many individuals do. If you are experiencing ongoing symptoms associated with erythrocytosis, it is advisable to schedule an appointment with your GP. Common symptoms include:

Common symptoms:

Headaches

Confusion

Dizziness

Blurred vision

Tiredness

Red skin, particularly in the face, hands and feet – this may be more difficult to see on black or brown skin

High blood pressure

Discomfort in the tummy

Bleeding problems – such as nosebleeds and bruising

Gout – which can cause joint pain, stiffness and swelling

Itchy skin – especially after a bath or shower

When to seek medical help

Erythrocytosis can lead to the formation of blood clots, which may result in serious health issues such as pulmonary embolisms—a blockage in the blood vessel that transports blood from the heart to the lungs—and deep vein thrombosis (DVT), which occurs when a clot forms in the veins of your leg and can travel to other parts of the body. It's essential to seek urgent medical attention if you or someone nearby exhibits symptoms of DVT or a pulmonary embolism. These symptoms include: pain, swelling, redness, and tenderness in one leg; a heavy sensation in the affected area; warmth in the area of the clot; shortness of breath; pain in the chest or upper back; coughing up blood; feeling faint or dizzy; and fainting. Additionally, erythrocytosis raises your risk of other complications.
