What causes limb weakness?

With the continuous development of science and technology, people's living standards have been greatly improved. However, due to various reasons in work and life, many office workers feel very tired and weak in their limbs. Generally speaking, if we have such a feeling, many people will think that it is caused by being too tired from work. In fact, this idea is incorrect.

Weakness in the limbs is just a simple symptom, not a disease. There are many reasons that cause weakness in the limbs, such as malnutrition and lack of sleep. Therefore, we should not take it lightly when we feel weakness in the limbs. Below, let us take a detailed look at the reasons that cause weakness in the limbs.

1. Diabetes is the disease that most often causes weakness in the limbs. Due to abnormal glucose metabolism, reduced high-energy phosphate bonds, negative nitrogen balance, water loss and electrolyte imbalance, patients are prone to fatigue, weakness, thirst, weight loss, polyphagia and polyuria.

2. Anemia also often causes fatigue. Severe cases include chronic anemia, sudden onset iron deficiency anemia, acute hemorrhagic anemia, acute hemolytic anemia, etc. These patients all experience weakness in the limbs.

3. Patients with chronic nephritis also often feel tired and weak in the limbs. Moreover, because they need to eat a low-salt or salt-free diet for a long time, they are prone to potassium deficiency. Therefore, weakness in the limbs, insomnia, and low back pain are often their main complaints when they seek medical treatment.

4. Many endocrine diseases cause weakness in the limbs. Weakness in the limbs is the first symptom of patients with hypothyroidism and is also a common symptom of patients with hyperthyroidism.

5. The most obvious fatigue and weakness are seen in patients with myasthenia gravis. Due to the patient's neuromuscular conduction disorder, their skeletal muscles are easily fatigued. After a little activity, they quickly become weak. Continuous and rapid movements are more likely to cause fatigue. The feeling of fatigue is often lighter in the morning and heavier in the evening. Supplementing with potassium chloride can relieve the weakness of the limbs.

6. Leukemia patients often feel weak in their limbs because they also suffer from anemia. In addition to leukemia, many malignant tumors often manifest as weakness in the limbs in the early stages, but are also accompanied by other common symptoms of the tumor. For example, lung cancer often has symptoms such as cough, hemoptysis, chest pain, etc.

The above are the causes of weakness in the limbs. We can see that there are many causes of weakness in the limbs. In addition to congenital reasons, endocrine, leukemia and other reasons can cause it. Therefore, when we feel frequent weakness in the limbs, we need to go to the hospital for examination and treatment in time.
