The Silent Threat of Hypertension: Symptoms and Treatment Guide

Hypertension is a condition in which the force of the blood against the artery walls consistently stays above normal levels. Also known in the medical world as the "silent killer," this disease often progresses without any symptoms, potentially causing severe damage to vital organs such as the heart, brain, and kidneys. Through regular health check-ups, early diagnosis, and the right lifestyle changes, keeping high blood pressure under control and preventing life-threatening complications is entirely in your hands.

• In Brief:
• Hypertension is defined as a consistent blood pressure reading of 140/90 mmHg or higher.
• In the vast majority of cases, there may be no physical symptoms for years.
• If left untreated, it can lead to heart attacks, strokes, and chronic kidney failure.
• Reducing salt intake and exercising regularly play a critical role in prevention.
• Even if you have no symptoms, checking your blood pressure at least once a year is vital.

What is Hypertension (High Blood Pressure)?

As the heart pumps blood throughout the body, it exerts a certain amount of pressure against the blood vessel walls. This is called blood pressure. The pressure when the heart contracts and pumps blood is known as systolic (the top number), and the pressure when the heart relaxes is diastolic (the bottom number). Ideal blood pressure readings are generally considered to be below 120/80 mmHg. When these numbers consistently remain at or above 140/90 mmHg, it answers the question of what hypertension is.

During a recent blood pressure screening event at BHT CLINIC İstanbul Tema Hastanesi, three out of every five participants were found to have high blood pressure. What is even more striking is that a large majority of these individuals were completely unaware of their condition and had no complaints whatsoever. This picture clearly illustrates why the disease is called a silent threat. The continuous high pressure that damages the inner lining of the arteries eventually causes them to harden and narrow, putting the entire body system at risk.

Causes and Risk Factors of High Blood Pressure

The causes of high blood pressure are generally divided into two main categories in medical literature. In "primary (essential) hypertension," which accounts for about 90 to 95 percent of cases, there is no single, identifiable underlying cause. This type usually develops gradually over many years due to a combination of advancing age, genetic predisposition, and lifestyle factors. Individuals with a family history of hypertension are at a much higher risk of developing it.

The remaining 5 to 10 percent of cases fall under "secondary hypertension." This condition appears suddenly as a result of an underlying medical issue, such as kidney disease, thyroid gland problems, sleep apnea, or adrenal gland tumours. Leading risk factors include excess weight, a sedentary lifestyle, high stress, excessive alcohol and tobacco use, and high sodium (salt) consumption. Additionally, metabolic issues that directly affect vascular health, such as high cholesterol, are major contributors that pave the way for elevated blood pressure.

What Are the Symptoms of High Blood Pressure?

As specialists frequently emphasise, high blood pressure is a sneaky disease. Even if a person feels perfectly fine and goes about their daily tasks without issue, their blood pressure could be at dangerous levels. Most patients do not notice any difference until the blood pressure rises high enough to damage organs. For this reason, high blood pressure symptoms typically appear in the advanced stages of the disease or during a crisis when blood pressure suddenly spikes to very high numbers.

When symptoms do arise, the most common complaints include morning headaches starting at the nape of the neck, ringing in the ears (tinnitus), dizziness, and palpitations. In more severe cases, nosebleeds, shortness of breath, chest pain, and vision disturbances can occur. These symptoms are often dismissed and attributed to everyday causes like fatigue or stress. Vague pains or palpitations, especially in the chest area, must be taken seriously as they can also be a harbinger of other severe cardiological issues like silent heart disease (silent ischemia).

How is Hypertension Diagnosed?

Contrary to popular belief, hypertension is not diagnosed with a single measurement. Blood pressure can fluctuate throughout the day depending on stress, physical activity, or the foods consumed. Therefore, for an accurate diagnosis, the patient must have rested for at least five minutes and not consumed caffeine or tobacco products in the half-hour prior to the measurement. Your doctor will make an assessment by taking the average of repeated measurements done on different days.

One of the most reliable methods during the diagnostic process is the "24-Hour Blood Pressure Holter" monitor. This device is attached to the patient's arm and automatically takes measurements at regular intervals for a full day, creating a detailed profile that includes blood pressure readings during sleep. Once high blood pressure is confirmed, additional tests such as blood tests (kidney function, blood sugar, cholesterol), a urine test, and an ECG (Electrocardiogram) to show the heart's electrical activity are requested to determine if the disease has caused any organ damage.

Hypertension Treatment and Prevention Methods

Successful hypertension treatment requires a combination of medication and lifestyle changes. Your doctor will plan the most appropriate medication regimen based on your age, any accompanying illnesses, and the severity of your blood pressure. It is crucial to take your medications regularly at the same time every day and not to stop them without consulting your doctor under the assumption that you are "cured" once your blood pressure normalises.

Alongside medical treatment, the changes you make to your daily habits are the main key to keeping your blood pressure under control. You can integrate the following steps into your life to protect yourself from hypertension and lower your readings:

• Reduce daily salt intake to under 5 grams (about one teaspoon).
• Engage in aerobic exercises, such as brisk walking or swimming, for 30 minutes at least five days a week.
• Avoid processed foods and adopt a diet rich in vegetables, fruits, and whole grains.
• Reach and maintain your ideal body weight.
• Practice stress management techniques and maintain a regular sleep schedule.

Furthermore, environmental factors are known to affect blood pressure. For example, during the summer months, sudden temperature changes can cause blood vessels to rapidly constrict and dilate, leading to blood pressure fluctuations. It is important to be mindful of such external factors.

Complications and Risk Groups of High Blood Pressure

Uncontrolled high blood pressure eventually leads to atherosclerosis (hardening of the arteries) due to the constant mechanical stress it places on the vessel walls. This means that all organs in the body are deprived of healthy blood flow. Because the heart has to pump blood against high resistance, its muscles thicken, eventually tiring out and leading to heart failure. At the same time, narrowing in the coronary arteries significantly increases the risk of a heart attack.

Damage to the blood vessels in the brain can result in an aneurysm (ballooning of a blood vessel), brain haemorrhage, or a stroke caused by a blood clot. The destruction of fine blood vessels in the kidneys can lead to chronic kidney failure, while damage to the vessels at the back of the eyes can cause permanent issues leading up to vision loss. Diabetics, smokers, those struggling with obesity, and the elderly are in the highest risk group for these complications.

When to See a Doctor?

Even if you have no complaints, it is recommended that every healthy adult over the age of 18 gets their blood pressure checked at least once a year. If you have a family history of hypertension or heart disease, it is in your best interest to have these checks done more frequently. If you experience frequent headaches, a feeling of heaviness in the back of your neck, or unexplained fatigue in your daily life, you should visit a healthcare facility without delay.

In some cases, blood pressure can suddenly spike to highly dangerous levels (180/120 mmHg and above). This scenario, known as a "hypertensive crisis," requires immediate medical intervention. If you experience high blood pressure accompanied by severe chest pain, shortness of breath, a severe headache with confusion, sudden blurred vision, difficulty speaking, or numbness and loss of strength on one side of your body, you should immediately call 112 or go to the nearest hospital emergency room.

Frequently Asked Questions

How is high blood pressure lowered?

Lowering high blood pressure is achieved through the regular use of blood pressure medications prescribed by a doctor and lifestyle changes. Reducing salt intake, reaching an ideal weight, exercising regularly, and avoiding stress are the most effective methods for lowering blood pressure.

Do lemon juice or garlic lower blood pressure?

Foods like lemon juice, garlic, or pomegranate molasses may have mild, temporary relaxing effects on the blood vessels, but they are not a medical treatment. It can pose life-threatening risks for hypertension patients to stop their medications and rely solely on such foods.

Are blood pressure medications used for life?

Hypertension is generally a chronic condition, and its treatment is long-term. For most patients, medication use continues for life. However, thanks to significant and permanent improvements in lifestyle, medication doses may be reduced under a doctor's supervision.

Does stress cause high blood pressure?

Sudden and intense stress increases adrenaline secretion in the body, temporarily raising blood pressure. Continuous chronic stress, on the other hand, negatively affects vascular health, making it a significant factor that paves the way for the development of permanent hypertension.

What should the ideal blood pressure be?

For a healthy adult, the ideal blood pressure reading is generally below 120/80 mmHg. However, the target blood pressure value should be determined personally by a doctor based on the patient's age and any accompanying health issues, such as diabetes or kidney disease.

To protect your cardiovascular health and detect potential risks at an early stage, you should not neglect your regular check-ups. You can book an appointment with our specialist doctors for a comprehensive evaluation.
