Why Do Elderly People Feel Weak, Lethargic, and Easily Tired?

Physical and mental fatigue in elderly people may be caused by insufficient sleep, osteoporosis, diabetes, and other factors.

1. Insufficient Sleep

If elderly people frequently stay up late and experience excessive mental stress, resulting in insufficient sleep at night, it usually leads to fatigue and lethargy during the day.

2. Osteoporosis

As people age, their bones gradually lose density, leading to osteoporosis. At this stage, due to low bone strength and increased brittleness, it may cause weakness. Moreover, after the onset of osteoporosis, the body's water-electrolyte balance becomes disturbed, causing systemic fatigue.

3. Diabetes

When blood sugar levels rise in elderly people, the body's glucose metabolism becomes disrupted. At this point, energy conversion is limited. When the body's energy supply is insufficient, it can cause systemic discomfort, drowsiness, and somnolence. If elderly people have malignant tumors, due to the rapid proliferation and spread of tumor cells in the body, normal cells will be affected and necrotic, consuming a large amount of energy and causing discomfort. Medical attention should be sought promptly to avoid delaying treatment.
