Zestril contains the active ingredient lisinopril. The medication belongs to a class of drugs called angiotensin-converting enzyme inhibitors. It caters to people with hypertension-related problems. Adults can also use Zestril to treat congestive heart failure and to improve their survival after a heart attack.

Blood vessels are constrictive in response to certain chemicals. By decreasing those chemicals, it blocks the action of an enzyme that causes blood vessels to constrict. By inhibiting this process, Zestril relaxes and widens blood vessels, allowing smoother blood flow. In addition to lowering blood pressure, this mechanism fosters improved circulation, which benefits the heart and kidneys.

Hypertension

Hypertension refers to elevated blood pressure levels in the arteries. In the absence of treatment, this persistent increase in pressure against the artery walls can lead to severe health complications. Systolic blood pressure (higher value) and diastolic blood pressure (lower value) are measured in millimeters of mercury.

Hypertension, often called the “silent killer,” is characterized by minimal to no symptoms in its early stages. Due to this deceptive nature, regular health checkups and blood pressure monitoring are crucial. Heart attacks, strokes, and kidney complications can result from untreated hypertension if left untreated.

Several factors influence the development of hypertension. Lifestyle choices play a significant role; poor diet, lack of exercise, and smoking can raise blood pressure. Additionally, genetic predisposition plays a role since hypertension tends to run in families. It can also be caused by underlying medical conditions such as Chronic Kidney Disease and Hormonal Disorders.

In contrast to managing hypertension’s consequences, preventing it is far more beneficial. Healthy eating habits can include reducing sodium intake and eating a diet rich in fruits, vegetables, and whole grains. In addition to maintaining a healthy weight, regular physical activity helps maintain a healthy blood pressure. Preventing stress through techniques such as meditation and yoga is also possible.

Hypertension must be managed effectively for individuals who already suffer from it. The role of a healthcare professional is crucial, prescribing medications based on the needs of the patient under medical supervision.
