The man's limbs are weak and his legs are limp.

When the hands and feet are weak, the first thing to do is to check the body, because if you blindly follow the trend of treatment without confirming the cause, the harm caused by medication will be greater. You should pay attention to the diabetes test and the blood sugar level test, because diabetics and anemic patients are very likely to have this symptom. Let's discuss what causes men's weakness and sore hands and legs?

1. Diabetes is the most common symptom that causes weakness in the limbs. Due to glycolysis disorders, reduced high-energy phosphate bonds, negative nitrogen balance, dehydration and electrolyte imbalance, patients are prone to fatigue, weakness, dry mouth, weight loss, polyphagia, and polyuria.

2. Anemia also often causes fatigue. More serious forms include chronic anemia, iron deficiency anemia with a more rapid onset, subacute hemorrhagic anemia, and subacute hemolytic anemia. Patients with these conditions all experience weakness in their limbs.

3. Patients with chronic nephritis often feel tired and weak in the limbs. 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 presenting medical history when they seek medical treatment.

4. Many endocrine diseases are manifested by weakness in the limbs. Weakness in the limbs is the initial symptom of patients with weakened thyroid cyst function, and is also a common symptom of patients with more hyperactive thyroid cyst function.

5. The most obvious fatigue is common in patients with myasthenia gravis, because the patient's neuromuscular transmission is blocked and the skeletal muscles are easily fatigued. After a little activity, fatigue will quickly appear. Continuous and rapid posture is more likely to cause fatigue. The fatigue is usually lighter in the morning and heavier in the evening. After supplementing with potassium chloride, the weakness of the limbs will be relieved.
