What should be done if an elderly person's blood pressure drops below 60?

Generally, hypotension refers to a systolic blood pressure below 90 mmHg or a diastolic blood pressure below 60 mmHg. In elderly individuals, low blood pressure may be caused by physiological aging, unbalanced diet, orthostatic hypotension, anemia, hypothyroidism, or other factors. It can be managed through general measures and medication. If discomfort occurs, timely medical consultation is recommended. Specific causes are analyzed as follows:

1. Physiological Aging

With advancing age, the cardiovascular system in older adults gradually deteriorates, including weakened myocardial contractility and reduced vascular elasticity. These changes may lead to decreased blood pressure. Maintaining a balanced diet and engaging in moderate physical activity can help preserve overall vitality.

2. Unbalanced Diet

An unbalanced diet lacking sufficient vitamins and minerals in older adults may result in reduced blood volume, leading to hypotension. It is advisable to develop healthy eating habits and consume fruits and vegetables rich in vitamins and minerals, such as apples, tomatoes, and carrots.

3. Orthostatic Hypotension

Due to diminished vascular regulatory function, elderly individuals may not quickly adapt to postural changes—such as suddenly standing up from a lying or sitting position—resulting in reduced venous return and a consequent drop in blood pressure. It is recommended to avoid prolonged standing or sudden changes in posture; rising from bed or standing should be done slowly.

4. Anemia

Chronic malnutrition can lead to anemia, reducing the blood's oxygen-carrying capacity and causing tissue and organ hypoxia, which may result in hypotension. Symptoms may include fatigue, palpitations, and shortness of breath. Consuming iron-rich foods such as spinach and pork liver is beneficial. Under medical guidance, medications such as ferrous sulfate tablets, ferrous fumarate tablets, or compound ejiao syrup may also be used to improve symptoms.

5. Hypothyroidism

Long-term iodine deficiency may lead to hypothyroidism, resulting in weakened myocardial contractility, slowed heart rate, and reduced cardiac output, thereby causing hypotension. Symptoms may include cold intolerance, excessive sleepiness, and memory decline. Ensuring adequate sleep—7 to 9 hours per day—is recommended. Under a doctor’s advice, medications such as levothyroxine sodium tablets, thyroid tablets, or prednisolone acetate tablets may be prescribed for treatment.

In daily life, it is important to maintain balanced nutrition, engage in moderate exercise, follow regular作息 (sleep-wake cycles), and avoid prolonged standing or sudden postural changes.
