What is the cause of weakness in the limbs joints

Weakness in the joints of the limbs may be a sign of illness, especially now that many people are susceptible to diabetes, anemia, chronic nephritis and endocrine diseases, and the typical symptoms of these diseases are also weakness in the joints of the limbs.

1. Diabetes

Diabetes is the disease most often causing 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

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. Chronic nephritis

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. Endocrine diseases

Many endocrine diseases present with 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. Myasthenia gravis

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 extremely easy to fatigue. 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

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.
