What Should Seniors Know About Blood Clots and DVT?
Deep vein thrombosis, or DVT, is a blood clot forming in a deep vein, usually in the leg. DVT is dangerous because clots can break loose and travel to the lungs, causing life-threatening pulmonary embolism. Understanding DVT risk and prevention helps seniors avoid this serious condition.
Understanding DVT
Blood clots form when blood flow slows, vein walls are damaged, or blood clotting tendency increases. Deep veins in the legs and pelvis are common sites. Clots block blood flow, causing swelling and pain in the affected limb.
The greatest danger is pulmonary embolism, when clot fragments travel through the heart to the lungs. PE can be rapidly fatal. DVT and PE together are called venous thromboembolism, a leading cause of preventable hospital death.
Risk Factors for Seniors
Age itself increases DVT risk as blood becomes more prone to clotting with age. Immobility from illness, surgery, or long travel allows blood to pool and clot. Hospitalization significantly increases risk, especially with surgery.
Cancer and cancer treatment increase clotting risk through multiple mechanisms. Heart failure slows blood flow. Previous DVT or PE strongly predicts recurrence. Family history of clotting disorders increases risk.
Obesity, smoking, hormone replacement therapy, and certain medications increase risk. The more risk factors present, the greater the cumulative danger.
Recognizing DVT
DVT symptoms include leg pain often starting in the calf, swelling of the affected leg, warmth over the affected area, and red or discolored skin. Symptoms typically affect one leg, not both. However, some DVTs cause no symptoms.
Pulmonary embolism symptoms include sudden shortness of breath, chest pain worsening with deep breathing, rapid heart rate, coughing up blood, and lightheadedness. PE is a medical emergency requiring immediate care.
When to Seek Emergency Care
Seek immediate medical attention for symptoms suggesting PE including sudden shortness of breath, chest pain, and rapid heartbeat. Call 911 rather than driving yourself. PE can deteriorate rapidly.
Seek prompt evaluation for leg symptoms suggesting DVT. While not immediately life-threatening, DVT requires diagnosis and treatment to prevent PE. Ultrasound can confirm or rule out DVT.
Prevention
Move regularly to maintain blood flow. During long sitting periods, flex feet and walk periodically. After surgery or illness, resume activity as soon as medically permitted. Avoid prolonged bed rest when possible.
Stay hydrated. Adequate fluid intake maintains blood flow and reduces clotting tendency. This is particularly important during air travel and illness.
Compression stockings reduce DVT risk during high-risk periods. Graduated compression promotes blood return from legs. Stockings are often recommended after surgery or during hospitalization.
Blood thinners are prescribed for high-risk patients. These medications prevent clot formation but carry bleeding risk. Follow medication instructions carefully.
Getting DVT Prevention Support
All Seniors Foundation provides education about DVT prevention and supports safe recovery from conditions increasing DVT risk. Prevention is far better than treating this dangerous condition. Contact us if you have questions about blood clot prevention.
