Even though you are well enough to leave hospital, you are still at risk of developing a Deep Vein Thrombosis (DVT) or Pulmonary Embolism (PE). This risk will continue until you return to your usual level of mobility.
What is a DVT?
A DVT is a blood clot that forms in a vein. It is possible for a DVT to form in any vein but it most commonly occurs in the leg.
What is a PE?
A PE is a blood clot in the lungs, caused when part of a DVT breaks off and travels in the bloodstream to the lungs.
What can I do to reduce my risk of getting a DVT or PE?
- Stay as mobile as possible. If walking is difficult, exercise your legs and feet by flexing your knees and ankles, rotating your feet and wriggling your toes. Do this as often as you can.
- Drink plenty of fluids, as dehydration increases the risk of getting a DVT or PE (Renal patients, please check your fluid allowance with your renal clinical team).
- If you have been given stockings or injections to reduce the risk of getting a DVT or PE, please use them as instructed.
- Eat a healthy diet and maintain a healthy weight.
- Don’t smoke.
How do I know if I have a DVT or PE?
Signs of a DVT include:
- Pain.
- Swelling.
- Discolouration of the skin (red, purple, or blue).
Signs of a PE include:
- A cough with or without blood-stained phlegm.
- Breathlessness - more than usual for you.
- Chest pain. Collapse (this is an emergency - phone 999).
If you develop any of the symptoms of either a DVT or PE, please get medical advice the same day. Phone 111 or your GP surgery, or go to the nearest A&E Department.
