Clause. Fourth, disuse muscle atrophy, this situation is most common in patients who have been bedridden for a long time, or patients who sit and work for a long time, do not exercise, and do not move.

If the muscle weakness is not caused by the disease, it can be considered whether it is a lack of nutrition and exercise.

3. Deficiency of qi and blood. Some patients need to stay in bed for a long time, and their legs become less mobile, weak, and even muscle atrophy. Long-term illness or serious illness will lead to a deficiency of qi and blood, which will not only cause weakness in the legs, but also cause other uncomfortable symptoms.

2. Cervical intervertebral disc herniation and lumbar intervertebral disc herniation can cause muscle weakness in the lower limbs, and the symptoms will be significantly aggravated after the patient walks for a certain distance, and the discomfort symptoms can be reduced after rest.

Weakness in the legs is due to the slow flow of qi and blood in the legs, resulting in the lack of qi and blood energy support in the leg muscles and bones, which will gradually degenerate, reduce the endurance, become weak, and make it difficult to walk.

It is either weak in its own body, insufficient qi and blood, or its own body and leg meridians and blood vessels are blocked by junk substances, toxins, cold and dampness, resulting in the slowing down of qi and blood.

To restore it, it is necessary to strengthen the physique, nourish enough qi and blood, enhance the body's energy and yang qi, speed up the flow of qi and blood around the body and legs, unblock the blockage of the body and legs, through the heat and sweating in the body, you can discharge the garbage and cold and dampness in the body with sweat, and over time, the qi and blood in the body and legs run smoothly, and sufficient qi and blood can nourish the leg muscles and muscles and bones, becoming strong and powerful.

Diabetes is the most common cause of fatigue. Patients are prone to fatigue, weakness, thirst, emaciation, polyphagia, polyuria and other symptoms due to abnormal glucose metabolism, reduction of high-energy phosphate bonds, negative nitrogen balance, water loss and electrolyte imbalance.

Anemia also often causes fatigue, and severe cases include chronic anemia, iron deficiency anemia with a sudden onset, acute hemorrhagic anemia, acute hemolytic anemia, etc., and these patients have fatigue. Patients with chronic nephritis also often feel tired and fatigued, and because they need to eat a low-salt or salt-free diet for a long time, and are prone to potassium deficiency, fatigue, insomnia, and backache are often their main complaints when they seek medical treatment.
