Leg weakness may be caused by myasthenia gravis, hypokalemia, lumbar intervertebral disc herniation, anemia, etc. There is no way to recover the fastest, and medication or surgery can be applied to treat the cause of the disease.
1. Myasthenia gravis: autoimmune disorder produces antibodies against acetylcholine receptors, resulting in the inability of acetylcholine at the neuromuscular junction to bind to the postsynaptic membrane receptors, resulting in neuromuscular transmission disorders and leg weakness. Neostigmine, prednisone and other drugs should be applied, and intravenous immunoglobulin or plasma replacement therapy should be given if necessary.
2. Hypokalemia: after the decrease of serum potassium ion concentration, the excitability of nerve cells will be reduced, and the nerve conduction obstacle will cause leg weakness. Potassium citrate, potassium chloride and other drugs need to be applied for treatment.
3. Lumbar intervertebral disc herniation: after lumbar intervertebral disc herniation, the adjacent spinal nerve roots are compressed, resulting in the dysfunction of the nerves that innervate the movement of the lower limbs, so the legs are weak and feeble. It can be treated by traction, massage, etc., and if necessary, surgery to relieve nerve compression.
4. Anemia: insufficient red blood cells and hemoglobin caused by various reasons, leading to severe ischemia and hypoxia of tissue cells, and leg weakness after involving the skeletal muscles of the lower limbs. According to the condition into the degree of blood transfusion treatment, and pay attention to supplement protein, iron, vitamin B and other nutrients, for the cause of anemia treatment.
Weakness of the legs may be related to a variety of factors, it is recommended to consult a doctor to clarify the diagnosis. Pay attention to the use of medication under the guidance of a physician.
