What your heart is trying to tell you: signals you shouldn't ignore

Five signs that may indicate a heart problem

The heart does not always communicate loudly. Some symptoms are subtle and are easily attributed to stress, fatigue, or aging. However, there are recurring signs that deserve serious attention.

Pain or pressure in the chest. This is the most well-known symptom of a heart problem. The sensation can vary from a stabbing pain to a heavy, oppressive feeling in the middle of the chest. Not every chest pain indicates a heart attack, but you should always seek medical help for persistent or sudden symptoms.

Shortness of breath without a clear cause. If you become breathless during minor exertions that used to be effortless, this may indicate a heart that has to work harder than normal. In heart failure, fluid accumulates in the lungs, making breathing difficult.

Extreme fatigue. A constant feeling of exhaustion, even after sufficient sleep, is one of the most underestimated signs. The heart pumps insufficient blood and oxygen to the muscles, causing you to feel tired and weak.

Dizziness and fainting. A brief, sudden bout of dizziness or fainting can indicate an irregular heartbeat or temporarily reduced blood flow to the brain.

Swelling of the legs and feet. When the heart does not pump blood efficiently, fluid accumulates in the lower limbs. This phenomenon is called edema and is a typical feature of heart failure in a more advanced stage.

In practice, we see that people sometimes downplay these complaints individually. However, if several of these symptoms occur simultaneously, it is a reason to contact a doctor quickly.

Why women experience heart problems differently

There is a persistent misconception that heart disease is a "men's problem." That is not the case. Women get heart disease just as easily, but the symptoms sometimes present differently. This leads to women seeking help too late more often, or their symptoms being recognized less quickly.

In men, the classic, oppressive chest pain is central. In women, the symptoms of heart failure or a heart attack can be more subtle. Pain on the left side of the chest is certainly not absent in women, but women more frequently report symptoms such as nausea, pain in the jaw, neck, or back, extreme fatigue, and shortness of breath, sometimes without clear chest pain.

In addition, a persistent cough, sometimes with light pink or white sputum, can indicate fluid accumulation in the lungs as a result of heart failure. Cognitive changes, such as forgetfulness or a foggy feeling in the head, are also reported in women with heart problems. Sudden weight gain due to fluid retention is likewise a signal that should not simply be attributed to diet.

It is important for women to know: if you do not feel well and your own body indicates that something is wrong, that is reason enough to have it investigated. Do not wait until the symptoms feel "serious enough."

Atrial fibrillation: when the heart follows its own rhythm

Atrial fibrillation is the most common heart rhythm disorder. With this condition, the electrical signals in the atria of the heart become disrupted, causing the heart to beat rapidly and irregularly. This reduces pumping efficiency and increases the risk of blood clots, which in turn can cause a stroke.

People with atrial fibrillation often describe the sensation as palpitations, a pounding or vibrating feeling in the chest, or the feeling that their heart is skipping a beat. Shortness of breath during exertion, dizziness, and fatigue are also common symptoms.

What makes atrial fibrillation particularly difficult is that it is symptom-free in a significant proportion of patients. This is called silent atrial fibrillation. The rhythm disorder is then discovered incidentally during a blood pressure measurement or an ECG. That is what makes it so dangerous: even without symptoms, the risk of a stroke remains elevated. Early detection and treatment are therefore essential.

Risk factors for developing atrial fibrillation include advanced age, high blood pressure, obesity, thyroid disorders, and excessive alcohol consumption.

High blood pressure: the silent threat to the heart

High blood pressure, or hypertension, rarely causes immediate symptoms. You may feel perfectly fine while your blood pressure has been too high for years. Nevertheless, it damages the blood vessel walls and structurally increases the workload on the heart. In the long term, this significantly increases the risk of heart failure, a heart attack, and a stroke.

What is normal blood pressure? Normal blood pressure is around 120/80 mmHg. High blood pressure is defined as a value that persistently remains above 140/90 mmHg. That sounds like a number, but the consequences are concrete: damaged blood vessel walls lose their elasticity, the heart has to pump harder and becomes overloaded, and minor damage to the vessel wall invites fat deposits that can lead to atherosclerosis.

What should you do about high blood pressure? A single high reading is no reason to panic; blood pressure naturally fluctuates throughout the day. Therefore, measure a few times at different moments before drawing conclusions. If the value persistently remains above 140/90 mmHg, make an appointment with your GP. They look not only at the number but also at your broader risk profile: age, weight, and family history.

When is it dangerous and when should you take immediate action? Seek immediate medical help in case of very high blood pressure, especially in combination with symptoms such as severe headache, shortness of breath, chest pain, or blurred vision. This can indicate a hypertensive crisis, in which the heart and blood vessels become acutely overloaded.

How and when do you measure your blood pressure? Preferably measure in the morning, before eating and before caffeine, in a quiet environment and with your arm supported at heart level. A single measurement says little; a few measurements spread over several days provide a much more reliable picture than a single snapshot.

The good news is that lifestyle changes have a proven effect. Less salt, more exercise, quitting smoking, moderation of alcohol, and a balanced diet can noticeably lower blood pressure. But for this, you must first know that your blood pressure is too high. To measure is to know.

What can you do to protect your heart?

Heart problems are largely preventable, or at least detectable early. This requires awareness and an active attitude. Specifically, these are the steps that make the most difference: Have your blood pressure measured regularly, especially if you have a family history of cardiovascular disease or are over 40 years old. Check your cholesterol and bloedsuiker. Elevated values ​​are important risk factors, but rarely cause symptoms. A blood test provides a definitive answer. Exercise regularly. At least 150 minutes of moderate exercise per week has a proven protective effect on the heart. Limit salt and saturated fats in your diet and eat more vegetables, fruit, and whole-grain products. Stop smoking and limit alcohol consumption. Both are direct risk factors for heart disease.

Do not delay visiting your GP if you have persistent symptoms such as shortness of breath, chest pressure, palpitations, or unexplained fatigue. Early intervention is always better than treating later.

When to have blood values ​​checked?

A blood test can tell you a lot about the health of your heart, even if you (still) feel well. Some abnormalities are present for months or years before they cause symptoms.

Consider having blood values ​​measured if:

• you have one or more risk factors, such as high blood pressure, being overweight, diabetes, or smoking;

• cardiovascular disease runs in your immediate family;

• you are persistently tired or become out of breath more easily than normal;

• you experience palpitations or an irregular pulse;

• you are over 45 years of age and have never had a heart health check.

Relevant blood values ​​include total cholesterol and LDL/HDL-verhouding, fasting bloedglucose, schildklierfunctie (can influence atrial fibrillation), and C-reactief proteïne (CRP) as a marker for inflammation in the blood vessels. A general practitioner or medical laboratory can help you further with this.

Conclusion: listen to your heart, literally

The heart requires little attention as long as everything is going well. But when it gives a signal, that signal deserves serious attention. Whether it concerns fatigue that does not go away, shortness of breath during minor exertion, chest pain on the left side, or a heartbeat that feels like a flapping bird: take it seriously and have it investigated.

Cardiovascular diseases are the leading cause of death worldwide, but they are also one of the most modifiable. With the right information, a healthy lifestyle, and timely medical check-ups, you can significantly reduce your risk. Have a blood test show where you stand, and discuss the results with a doctor. Your heart works for you every day. It pays to work for your heart too.
