Medical professionals have issued a critical alert regarding the dangers of blood clots, a condition that affects thousands of individuals each year and can be life-threatening without prompt treatment. The warning gained urgency following the recent death of actress Catherine O’Hara, who reportedly succumbed to a pulmonary embolism, a type of blood clot that lodges in the lung, during her cancer treatment. This incident has highlighted the importance of recognizing the symptoms associated with blood clots and seeking immediate medical attention.
Understanding Blood Clots and Their Risks
During an appearance on BBC’s Morning Live, Dr. Punam Krishan discussed the critical nature of blood clots and outlined how individuals can reduce their risk of developing this serious health issue. Each year, approximately 60,000 people in the UK require treatment for blood clots, and early detection can significantly enhance treatment outcomes.
Dr. Krishan explained, “When we hear the word ‘blood clot’, immediately it sends a fright, and not all clotting is bad. Our bodies are naturally designed to clot to stop bleeding. It’s there to protect us; the problem is when you end up with a clot somewhere it should not be.” She emphasized that one of the most common locations for problematic clots is in the deep veins of the legs, often affecting just one leg.
The most severe complication occurs when these clots dislodge and travel to the lungs, resulting in a pulmonary embolism, which Dr. Krishan described as “potentially life-threatening.”
Identifying High-Risk Groups
While blood clots can affect anyone, certain populations face a heightened risk. Dr. Krishan identified several key groups, including individuals who are:
- Over the age of 60
- Overweight
- Regular smokers
- Taking oral contraceptives or hormone replacement therapy (HRT)
- Undergoing cancer treatment
- Having a family history of heart failure, varicose veins, or previous blood clots
Additionally, Dr. Krishan noted that temporary risk factors can elevate the likelihood of developing blood clots. For instance, women who have recently given birth remain at increased risk for several weeks postpartum. Long journeys exceeding three hours, whether by train, plane, or car, can also contribute to elevated risk due to restricted mobility. Blood clots are particularly prevalent during hospital stays, following surgical procedures, or during extended periods of bed rest.
The NHS offers guidance on how to prevent blood clots and respond in emergencies. Recommendations include maintaining regular movement, walking frequently, staying well-hydrated, avoiding prolonged sitting, and quitting smoking.
If individuals experience symptoms such as leg pain, swelling, chest discomfort, or breathing difficulties, they should seek immediate medical assistance by calling 999 or going to an accident and emergency department.
“A blood clot is not life-threatening by itself. However, sometimes it can move out of position and travel, blocking the blood supply to your lungs. This type of blood clot is called a pulmonary embolism (PE) and can be life-threatening,” cautioned the NHS.
Symptoms that warrant urgent medical attention include:
- Chest pain
- Shortness of breath
- Feeling sweaty and unwell
- Fainting
- Coughing up blood
Symptoms can vary based on the location of the clot, but generally may include pain, swelling, tenderness, warmth, and redness in the affected area. In cases of pulmonary embolism, warning signs may include sudden breathlessness, sharp chest pain, and a rapid heartbeat. The NHS strongly advises people to seek emergency help if they develop these concerning symptoms.
Common medications, such as apixaban and rivaroxaban, which serve to thin the blood and prevent additional clots from forming, are typically prescribed for those diagnosed with blood clots.
As awareness grows regarding the implications of blood clots, it is crucial for individuals to recognize the signs and take proactive steps toward prevention and treatment. Understanding the risks and being vigilant can save lives.
