Tired legs are a fairly common symptom with a variety of underlying factors. You may have an increased risk for tired legs if you are female, overweight, or older. Tired legs can also occur in people who regularly sit or stand for extended periods of time.
A variety of factors can cause tired legs. Tired legs may be accompanied by pain, soreness, or cramping. Tired legs are not usually a cause for concern, but it is still important to pay attention to your body when tiredness occurs. This is especially so if you have other symptoms.
Here are some possible causes for tired legs:
Overuse
If you have recently used your legs more than normal, they may feel tired. Make sure you are getting enough rest and working within the limits of your body. This will help you avoid stress, strain, and injury.
If you frequently use your legs while working, take plenty of breaks throughout the day.
Underuse
Not using your legs can also cause leg tiredness. If you have to sit for extended periods, make a point to stand and be active for at least five minutes every hour.
If you are spending an extended amount of time in bed, do simple leg-raising exercises and stretches each hour. Elevate your legs on pillows.
Muscle cramps
Overuse of your legs can lead to muscle cramps. Muscle cramps can cause your legs to feel tired.
Allow your legs and body plenty of time to rest until your symptoms subside. See your doctor if cramping becomes severe. Here are more ways to stop leg muscle cramps.
Hypokalemia
Hypokalemia occurs when you have low levels of potassium in the bloodstream. This can cause:
- fatigue
- weakness
- cramping in the legs
- constipation
- Certain medications or conditions may cause hypokalemia. See your doctor to determine the underlying cause and best treatment option for you.
Varicose veins
You may have tired, heavy, or aching legs if you have varicose veins. These occur when your veins do not work properly and begin to collect blood. This causes your veins to enlarge and swell.
Usually self-care measures, such as exercise, elevation, and compression stockings, can help alleviate these symptoms. See your doctor if your symptoms do not improve.
Poor circulation
Your legs may feel tired or fatigued if your blood is not circulating through your body properly. Poor circulation often affects the lower part of your body since it is harder for blood to flow upward toward your heart. Sometimes blood can collect in your legs, ankles, and feet.
You may be able to improve poor circulation by:
- moving more
- avoiding tight clothing
- managing underlying conditions, such as diabetes
See your doctor if you have taken steps to improve your circulation but have not seen improvement. Your doctor may prescribe medication to improve your circulation.
Pregnancy
Swelling in pregnancy can be caused by:
- hormones
- fluid retention
- increased pressure on veins
Your legs may feel tired and uncomfortable as a result. You may experience cramping and varicose veins.
Sleeping on your left side can help reduce some of the pressure from the vein that circulates blood from your lower body to your heart. You can also try these five exercises.
See your doctor if you experience any sudden or severe swelling. This could be a sign of preeclampsia.
