What lifestyle changes help during treatment?
Lifestyle changes are a fundamental part of recovering from a blood clot and preventing recurrence. While anticoagulant medication stops the clot from growing, physical and habit-based adjustments help improve circulation, reduce swelling, and address the underlying factors that led to the clot in the first place. In the UK, the NHS emphasizes a balanced approach focusing on safe movement, hydration, and weight management to ensure the best long-term outcomes after a diagnosis of deep vein thrombosis (DVT) or pulmonary embolism (PE).

Safe movement and circulation
One of the most effective lifestyle changes is staying mobile. In the past, patients were often told to remain on bed rest, but modern medical advice has shifted. Moving helps the calf muscles act as a pump, pushing blood back toward the heart and preventing it from pooling in the lower legs. For those recovering from a DVT, short, frequent walks are recommended as soon as the initial pain allows.
If your job involves sitting for long periods, it is essential to incorporate ‘circulation breaks’ every hour. Simple movements like ankle pumps or stretching while seated can make a significant difference. However, it is important to avoid high-impact sports or activities with a high risk of falling while on blood thinners, as these medications increase the risk of internal bleeding if an injury occurs.
Hydration and blood health
Staying well-hydrated is a simple but vital change. When the body is dehydrated, the blood can become more concentrated and ‘sticky’, which potentially reduces the effectiveness of your natural clotting balance and the circulation of your medication. Aiming for approximately 1.2 to 2 litres of water a day is standard advice in the UK.
You should also be mindful of alcohol and caffeine. While moderate amounts are generally safe, excessive alcohol can lead to dehydration and increase the risk of falls. Furthermore, for those on warfarin, large changes in alcohol intake can interfere with how the liver processes the medication, leading to fluctuations in your INR levels.
Smoking cessation and vascular integrity
Stopping smoking is perhaps the most significant long-term lifestyle change a patient can make. Smoking damages the endothelium (the inner lining of the blood vessels) and increases the levels of fibrinogen in the blood, both of which are major contributors to clot formation. By quitting, you allow your vascular system to begin healing and significantly lower your risk of a second clot or a stroke.
The NHS provides extensive support for quitting, including nicotine replacement therapies and local support groups. Because the damage from smoking is cumulative, quitting at any stage of your DVT or PE treatment will provide immediate benefits to your circulatory health and improve the efficiency of your recovery.
Causes of clotting influenced by lifestyle
Many of the underlying causes of venous thromboembolism are exacerbated by lifestyle factors. For instance, chronic venous insufficiency where the veins struggle to send blood from the limbs back to the heart is worsened by a sedentary lifestyle. By addressing these habits, you are treating the ‘environment’ in which the clot formed.
Lifestyle-related causes include:
- Obesity: Which increases intra-abdominal pressure and slows blood flow from the legs.
- High blood pressure: Which can stress the vascular system over time.
- Chronic inflammation: Often linked to a diet high in ultra-processed foods.
- Prolonged immobility: A primary cause for those in office-based roles or frequent travellers.
Triggers and habit modification
Triggers are the specific events that can cause a clot to develop. Habit modification involves identifying these triggers in your daily life and creating a ‘safety plan’ to mitigate them. For example, if you know you have a long car journey or flight approaching, you can modify your habits to include wearing compression socks and performing seated exercises.
Common triggers to manage include:
- Long-distance travel: Planning for breaks every two hours to walk around.
- Starting new medications: Discussing the clotting risk of any new hormones or treatments with your GP.
- Periods of illness: Ensuring you stay mobile and hydrated even when feeling unwell.
- Occupational risks: Using standing desks or footrests to improve ergonomics and blood flow.
Differentiation: Diet and medication types
It is important to differentiate lifestyle advice based on the type of anticoagulant you are taking. If you are on a Direct Oral Anticoagulant (DOAC) like apixaban, there are very few dietary restrictions. However, if you are on warfarin, your diet must be consistent. This is because Vitamin K found in green leafy vegetables like spinach and kale works against warfarin.
You do not need to avoid these healthy foods, but you must keep your intake stable. A sudden increase or decrease in Vitamin K can cause your blood-thinning levels to become too high or too low. Always discuss major dietary changes with your anticoagulant clinic to ensure your dose remains safe and effective.
Conclusion
Lifestyle changes are a powerful tool in your recovery journey, working alongside your medication to restore vascular health. By staying active, hydrated, and smoke-free, you are not just recovering from your current clot, but actively protecting yourself against future episodes. Small, consistent adjustments to your daily routine are the key to a safe and sustainable recovery.
If you experience severe, sudden, or worsening symptoms, call 999 immediately.
‘When can I start exercising properly again?’
Most people can return to gentle walking immediately. More vigorous exercise should be discussed with your doctor, usually after your first follow-up appointment.
‘Can I still drink coffee while on blood thinners?’
Yes, moderate caffeine intake is generally fine, but ensure you are also drinking plenty of water to avoid dehydration.
‘Should I change my diet if I am on apixaban?’
No specific dietary changes are required for apixaban, but a heart-healthy diet low in processed salt and sugar is always beneficial for circulation.
‘Is it safe to go to the gym?’
Light gym work like a stationary bike or elliptical is often fine, but avoid heavy weightlifting or contact sports until cleared by a specialist.
‘How much weight do I need to lose?’
Even a small, gradual weight loss can reduce the pressure on your leg veins. Your GP can provide a referral to a weight management service if needed.
‘Can I use a sauna or steam room?’
Heat can cause your blood vessels to dilate and may lead to dizziness if you are on certain medications. It is best to wait until your symptoms have stabilised.
‘Do lifestyle changes mean I can stop my medication earlier?’
No. Medication duration is based on the risk of recurrence. Lifestyle changes reduce that risk, but you must complete the full course as prescribed.
