Smoking is a well-known risk factor for a variety of health problems, including lung cancer, Heart diseaseand chronic respiratory conditions. However, one of the lesser-known dangers of smoking is that it significantly contributes to the formation of cancer. blood clotsWhich can lead to life-threatening conditions such as deep vein thrombosis (DVT), pulmonary embolism and stroke. Cigarette smoke damages the lining of blood vessels, increasing the risk of blood clots.
Hence, it is essential to know the warning signs and strategies to manage it to minimise the risk of blood clots. We got in touch with Dr Meet Kumar, Director and HOD- Hemato-Oncology. bone marrow Transplant, Marengo Asia Hospital Gurugram who shares hints and effective tips.
Symptoms of a blood clot
It is important to recognise the warning signs and symptoms of blood clots as these conditions can turn into life-threatening emergencies. Dr Meet Kumar explains that blood clots can occur in various parts of the body, leading to conditions such as deep vein thrombosis (DVT) or pulmonary embolism (PE), both of which require immediate attention.
Deep vein thrombosis (DVT) occurs in the deep veins of the legs, although it can also develop in other areas of the body. Symptoms of DVT in the affected limb include warmth, redness, pain, and swelling. These symptoms often appear in the calf or thigh and may worsen over time. DVT can occur after prolonged periods of inactivity, such as during long flights or prolonged periods of bed rest, so awareness of risk factors is essential.
Pulmonary embolism (PE), a more serious complication of blood clots, occurs when the clot travels from the deep veins to the lungs, blocking blood flow. The symptoms of a PE can be sudden and frightening, including rapid breathing, severe chest pain, coughing up blood, and a rapid heartbeat. These signs indicate that the body’s ability to supply oxygen to vital organs has been reduced, which can be fatal if not treated promptly.
Strategies to Reduce Blood Clot Risk
Given the link between smoking and blood clots, it’s important to adopt strategies to reduce the risk. Here are some evidence-based approaches:
1. Quit smoking
The most effective way to reduce your risk of blood clots is to quit smoking. Quitting smoking can significantly reduce your risk of blood clots in just a few weeks. A study published in The Lancet found that people who quit smoking had a 50% reduced risk of recurrent VTE after just one year, compared to those who continued to smoke.
2. Be active
Regular physical activity improves blood circulation and reduces the risk of blood clots. Exercise helps maintain a healthy weight, lowers blood pressure and reduces the chance of clots. The American Heart Association recommends at least 150 minutes of moderate-intensity exercise per week.
3. Maintain a healthy diet
A balanced diet rich in fruits, vegetables, whole grains, and lean protein can help reduce the risk of blood clots. Foods rich in omega-3 fatty acids, such as salmon and flax seeds, have anti-inflammatory properties that may reduce the risk of clot formation.
4. Manage long-term conditions
Conditions such as high blood pressure, diabetes, and high cholesterol can increase the risk of blood clots. Managing these conditions through medication, diet, and lifestyle changes is essential to reduce the overall risk.
5. Stay hydrated
Dehydration can cause blood to thicken, which increases the risk of clots. Drinking plenty of water throughout the day helps keep blood flowing smoothly.
6. Avoid long periods of inactivity
Sitting or lying down for long periods of time, such as during long flights or while on bed rest, can increase your risk of blood clots. Taking regular breaks to move around and stretch can help prevent clots.
