Disease description:

My mother has had hypertension for a long time and has been managing it with antihypertensive medication. However, during her blood pressure checks over the past few days, we noticed something unusual with her readings. Could you please explain why her blood pressure appears to fluctuate markedly—alternating between high and low values?

Hypotension is primarily caused by low blood pressure, which may lead to symptoms such as dizziness, lightheadedness, fatigue, syncope, and dark circles under the eyes. Severe hypotension can even impair the ability to stand upright. However, most individuals with hypotension remain asymptomatic. Management typically involves increased physical activity to improve overall fitness, along with dietary modifications—such as consuming foods higher in fat and salt. In contrast, hypertension is primarily caused by elevated blood pressure. It may cause symptoms including headache, nausea, and vomiting; if severe or uncontrolled, it can lead to serious cardiovascular, cerebrovascular, and renal complications—such as intracerebral hemorrhage and renal insufficiency. Standardized antihypertensive drug therapy is essential for its management.
