What causes weakness in the limbs

It is important to understand the causes of limb weakness, because for many people it is caused by certain diseases in the body, especially people with diabetes, chronic nephritis, and some endocrine diseases, who are prone to these symptoms.

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.

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.

2. 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.

3. 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.

4. 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.
