What causes heavy and weak legs?

In general, leg weakness or difficulty lifting the legs may be caused by prolonged standing, lack of exercise, anemia, synovitis, lower extremity varicose veins, and other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under a doctor's guidance. Specific analyses are as follows:

1. Prolonged standing: Maintaining the same posture for extended periods, such as standing, can keep leg muscles in constant tension, leading to muscle fatigue and a feeling of weakness. Regular breaks, changing postures appropriately, and performing leg stretching exercises can help improve blood circulation.

2. Lack of exercise: Long-term physical inactivity can lead to decreased muscle strength and endurance, making the legs feel weak more easily. Daily activity levels should be gradually increased through aerobic exercises such as walking, swimming, or cycling to enhance muscle strength and endurance.

3. Anemia: Low hemoglobin levels in the blood result in insufficient oxygen and blood supply to organs, causing symptoms such as dizziness and generalized weakness. Patients should follow medical advice to take medications such as ammonium ferric citrate vitamin B1 syrup II, polysaccharide-iron complex capsules, or Shengxuebao mixture.

4. Synovitis: Inflammation affecting the synovial membrane in the hip joint can restrict joint movement and cause pain, thereby impairing walking ability. Symptoms may include hip pain, swelling, and limited mobility. Patients may take medications such as methylprednisolone tablets, ibuprofen capsules, or celecoxib capsules as directed by a physician.

5. Lower extremity varicose veins: Prolonged sitting or standing can lead to varicose veins, impairing blood circulation in the legs and causing leg pain, heaviness, and difficulty lifting the legs. Other possible symptoms include darkened skin on the lower limbs, visible bulging veins, and edema. Medications prescribed by a doctor may help relieve symptoms; commonly used drugs include diosmin tablets, sodium aescinate tablets, and dicoumarol tablets.

Adequate rest should be maintained in daily life, and strenuous exercise should be avoided. A diet rich in fresh vegetables and fruits with sufficient nutritional intake is beneficial for recovery.
