High blood pressure (Hypertension) can be a silent killer because most patients often show no warning symptoms. However, persistently high blood pressure can slowly damage blood vessels and vital organs. If left uncontrolled, this disease leads to life-threatening complications such as heart failure, stroke, and chronic kidney failure.
Understanding the disease and using antihypertensive medications correctly is, therefore, key to taking care of yourself.
Blood pressure is the force exerted by circulating blood against the walls of the body's arteries as the heart pumps and relaxes. Readings consist of the upper value (systolic), which is the pressure when the heart beats, and the lower value (diastolic), which is the pressure when the heart rests. Hypertension occurs when blood pressure is higher than 140/90 mmHg.
The causes of hypertension are divided into two main groups. Primary Hypertension (Essential Hypertension) is found in the majority of patients (more than 90%). Its specific cause cannot be identified, but it is believed to result from a complex interaction of genetic factors, environmental factors, and lifestyle behaviors. The second type is Secondary Hypertension, found in about 5-10% of cases. This is caused by other diseases or abnormalities in the body that directly affect blood pressure control. If the underlying cause is treated, blood pressure often returns to normal. Examples include chronic kidney disease, renal artery stenosis, adrenal tumors, certain thyroid diseases, and obstructive sleep apnea.
Regardless of the type, other factors act as catalysts that cause blood pressure to spike and become difficult to control. These include aging, which causes blood vessels to harden and become less elastic; family history, as those with parents or direct relatives with hypertension have a higher risk; and gender, where men generally have a higher risk, but women’s risk increases significantly after menopause.
Additionally, behavioral factors play a role, including obesity, which forces the heart to work harder to pump blood; high sodium intake (eating salty foods), which causes the body to retain water, increasing blood volume and pressure; heavy alcohol consumption, which damages the heart and raises blood pressure; and smoking. Nicotine in cigarettes accelerates the heart rate, constricts blood vessels, and damages vessel walls, leading to atherosclerosis. Lack of exercise and chronic stress are also significant risks; long-term accumulated stress can lead to permanent hypertension. Other chronic diseases like diabetes and high cholesterol also increase the risk, as they contribute to blood vessel damage.
Therefore, once diagnosed with hypertension, besides strictly taking medication as prescribed, changing risky behaviors is essential. Reducing smoking and alcohol, losing weight, controlling salt intake, treating other chronic diseases, and exercising appropriately are all vital for keeping blood pressure within target goals.
There are various groups of medications used to lower blood pressure, each with different mechanisms aimed at reducing pressure in blood vessels and protecting vital organs. All these medications must be used under a doctor's advice only. Patients must strictly not stop medication on their own. stopping medication without medical supervision can cause a severe rebound in blood pressure, leading to dangerous complications like a sudden stroke. However, if any side effects occur, consult a doctor or pharmacist immediately to adjust the medication. Using medication consistently, combined with disciplined diet and lifestyle control, ensures the most effective blood pressure management.
