What causes sudden dizziness and leg weakness in a 70-year-old elderly person, and what should be done?

A 70-year-old elderly person suddenly experiencing dizziness and leg weakness may be due to physiological factors, or pathological causes such as iron deficiency anemia or hypertension. Treatment can involve general management and medication. Specific details are as follows:

1. Physiological Factors

If the elderly individual has recently experienced insufficient sleep, it may lead to excessive fatigue in both the brain and body, resulting in symptoms such as headache and generalized weakness. It is important to get adequate rest and avoid overexertion.

2. Pathological Factors

1) Iron Deficiency Anemia

Iron deficiency anemia is caused by insufficient iron and is characterized by microcytic hypochromic anemia. This condition leads to cerebral hypoxia, causing symptoms such as dizziness and limb weakness. Under medical guidance, treatment may include oral medications such as protein succinic acid iron solution or ferrous succinate tablets.

2) Hypertension

Hypertension is typically a cardiovascular syndrome primarily characterized by elevated systemic arterial pressure. In elderly patients with a history of hypertension, poor blood pressure control may result in symptoms such as leg weakness and nausea. Under medical supervision, medications such as nifedipine controlled-release tablets or clopidogrel hydrogen sulfate tablets may be prescribed for treatment.

In addition to the above causes, dizziness and leg weakness could also result from insufficient cerebral blood supply, cerebral hemorrhage, or cerebral infarction. Attention should be paid to dietary adjustments, including increased intake of protein-rich foods. Individuals experiencing these symptoms should seek timely medical evaluation and follow standardized treatment under a physician's guidance to promote recovery.
