What causes sudden leg weakness in the elderly, and what should be done?

Generally, sudden leg weakness in elderly individuals may be caused by physiological factors or pathological conditions such as anemia or cerebral infarction. Appropriate treatment should be based on the specific cause. The details are as follows:

I. Physiological Factors

If elderly individuals frequently have irregular eating habits or insufficient sleep, it may lead to inadequate energy in the body, resulting in sudden feelings of leg weakness. Symptoms usually improve with better nutrition and adequate rest, and no special treatment is required.

II. Pathological Factors

1. Anemia

Anemia is relatively common in the elderly. Severe anemia can impair oxygen supply to the body, leading to symptoms such as leg weakness and general fatigue. It is recommended that patients maintain a balanced diet, consume more high-protein and high-vitamin foods, and engage in appropriate physical activity, which generally helps improve the condition.

2. Cerebral Infarction

This is a common cerebrovascular disease referring to ischemic necrosis or softening of localized brain tissue due to impaired cerebral circulation, causing ischemia and hypoxia. Patients often experience sensory disturbances, nausea, vomiting, and may suddenly feel leg weakness. It is recommended that patients take medications such as enteric-coated aspirin sustained-release tablets and clopidogrel hydrogen sulfate tablets as prescribed by a physician.

In addition, other possible causes include intracerebral hemorrhage, Parkinson's disease, multiple sclerosis, lumbar disc herniation, and myasthenia gravis. Individuals experiencing discomfort should seek timely medical attention to avoid delays in treatment. Additionally, maintaining a light diet and ensuring adequate rest in daily life are also important.
