Dizziness and heavy eyelids in the elderly may be caused by physiological factors or pathological factors such as hypertension, insufficient blood supply to the brain and anemia. 1. Physiological factors: insufficient rest, overwork, emotional fluctuations, etc. can lead to dizziness and heavy eyelids, which can be relieved by resting. 2. Hypertension: When the elderly suffer from hypertension, unstable blood pressure will lead to dizziness and heavy eyelids. It is recommended to monitor the blood pressure and actively control the blood pressure to avoid too high or too low blood pressure. 3. Insufficient blood supply to the brain: When the blood vessels inside and outside the skull are narrowed or occluded, it may lead to insufficient blood supply to the brain, resulting in dizziness and heavy eyelids in the elderly. 4. Anemia: when the elderly have severe anemia, due to the reduction of blood volume and effective circulation, it may lead to insufficient blood supply to the brain, which will cause dizziness and heavy eyelids. It is recommended to go to the hospital in time and take targeted treatment under the doctor’s examination.
