Those with DVT or taking blood-thinning medications for DVT may need to avoid certain activities, medications, foods, or lifestyle factors.
People will need to avoid certain factors that may increase the risk of blood clots in the veins or interfere with blood thinners.
This article looks at what people will need to avoid with DVT.
It also discusses helpful tips and when to see a doctor.
A 2022 systematic review notes that exercise is safe for those with DVT. Additionally, a
However, the National Blood Clot Alliance advises people to avoid high-risk sports, such as contact sports, which may result in injury. This is because blood thinners can increase the risk of serious bleeding complications.
People should also wear protective safety gear during certain activities, such as a helmet when cycling.
What exercise can a person with DVT take part in?
Any moderate exercise, such as walking or swimming, may be beneficial. Aerobic exercise can also help to improve lung function if a person has had a pulmonary embolism.
Those with DVT who take warfarin — a type of blood thinner — may need to be cautious about their vitamin K intake.
Suddenly increasing vitamin K intake alongside warfarin can cause blood clots, and a sudden decrease may cause serious bleeding.
The ODS states that people taking warfarin should consume roughly the same amounts of vitamin K each day from food or supplements.
Sources of vitamin K in foods include green leafy vegetables, such as:
Other sources of vitamin K include:
- vegetable oils
- certain fruits, including blueberries and figs
People will also need to limit their intake of certain drinks that
- cranberry juice
- grapefruit juice
If people have any concerns about vitamin K consumption, they should speak with a healthcare professional. There are other types of blood thinners a person can take to treat DVT that does not require them to monitor their vitamin K levels.
Lifestyle factors to avoid include:
- Smoking: People will need to avoid smoking with DVT. Smoking increases the risk of heart attack, stroke, and other conditions. These can increase the risk of blood clots occurring in the veins.
- Being too sedentary: Regular movement is important during recovery and to prevent a repeat DVT. People can speak with a healthcare professional about the right levels of physical activity.
- Having overweight or obesity: Aiming for and maintaining a healthy weight is also important in managing DVT because having obesity is a risk factor for blood clots reoccurring.
- Stress: Avoiding stress as much as possible is also an important factor in lowering the risk of blood clots. Stress can increase the risk of certain conditions, such as stroke or heart attack, which may cause VTE.
- Bleeding risks: Small cuts or injuries may bleed more than normal with blood thinners. People can use a soft toothbrush, take care when cutting nails, and avoid going barefoot.
People with DVT should let a doctor know if they are taking any medications, as well as any herbs or supplements.
Certain medications can interact with warfarin and
- other types of blood thinners
- nonsteroidal anti-inflammatory drugs (NSAIDs)
- antiplatelet medications
- anti-arrhythmic drugs
Hormone therapies can increase the risk of serious blood clots in people with a personal or family history of blood clots. During menopause, people with a history of blood clots will need to take blood thinners alongside hormonal therapy.
