hypertension in hypothyroidism

Hypothyroidism may result in hypertension due to the influence of low thyroid hormone levels on cardiac and renal functions, which can lead to elevated blood pressure. However, hypertension is not a universal symptom among individuals with hypothyroidism, as blood pressure variations are also influenced by other factors.

When thyroid hormone levels drop, the heart rate may decrease, and cardiac output may diminish, potentially increasing vascular resistance and consequently raising blood pressure. Additionally, thyroid hormones affect the kidneys by regulating sodium excretion; in hypothyroidism, the kidneys' sodium excretion capacity is reduced, leading to sodium and water retention in the body, which can also cause an increase in blood pressure. Therefore, it is crucial for individuals with hypothyroidism to monitor their blood pressure regularly and adjust their treatment plan under a physician's guidance.

Maintaining a healthy lifestyle is equally important for individuals with hypothyroidism to manage blood pressure. This includes adopting a healthy diet, limiting sodium intake, maintaining a healthy weight, engaging in regular physical activity, and abstaining from smoking and excessive alcohol consumption. Patients should also adhere to their doctor's recommendations, regularly checking thyroid hormone levels and blood pressure to ensure timely adjustments to their treatment regimen.
