Why can't I use my hands?

I believe that many people have problems with weak arms and inability to exert strength. This physical problem is mainly caused by two types of reasons. One is physiological reasons, such as malnutrition, excessive fatigue, etc., which can lead to arm weakness. The other is pathological problems, such as diabetes, anemia, chronic nephritis, endocrine diseases, postpartum hemorrhage, myasthenia gravis or leukemia, which can cause arm weakness.

1. Physiological reasons:

Malnutrition, overwork, and depression are all physiological reasons. The limb weakness caused by these reasons is mostly temporary and does not require treatment with medication. As long as you supplement nutrition and pay attention to rest, this phenomenon will gradually disappear.

2. Pathological causes:

Limb weakness is one of the common complications of liver disease, diabetes, chronic nephritis, and leukemia.

1. Diabetes

Diabetes is the most common disease causing fatigue. 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 fatigue.

3. Chronic nephritis

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

4. Endocrine diseases

Many endocrine diseases present with fatigue. Fatigue is the first symptom of patients with hypothyroidism and is also a common symptom in patients with hyperthyroidism.

5. Postpartum hemorrhage

Sheehan's syndrome caused by shock due to postpartum hemorrhage is mainly manifested by fatigue, amenorrhea, and weight loss, which is due to hypopituitarism. Patients with acromegaly caused by hyperpituitarism also often feel fatigue and weakness in the limbs.

6. 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. Fatigue can be relieved after supplementing with potassium chloride.

7. Leukemia

Leukemia patients often feel weak because they also suffer from anemia. In addition to leukemia, many malignant tumors often manifest as fatigue symptoms 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.
