Why might a patient with severe hypertension be advised to restrict physical activity?

Patients with severe hypertension are often advised to restrict physical activity primarily to reduce the risk of complications such as stroke or cardiovascular events. Severe hypertension can significantly increase the burden on the cardiovascular system, and engaging in strenuous activities can exacerbate this risk.

In cases of severe hypertension, the body may already be under stress, and additional strain from physical activity could lead to detrimental outcomes like hypertensive crises or organ damage. By limiting physical exertion, the patient can help stabilize their blood pressure and minimize the likelihood of acute complications, ensuring a safer environment both for themselves and their developing fetus.

This cautious approach is essential in managing hypertensive disorders in pregnancy, where maintaining optimal blood pressure levels is critical for maternal health and reducing risks associated with severe hypertension.
