The heart works like an engine for the body. It keeps you alive by pumping blood to your organs and tissues.

But like any engine, it can encounter problems. Recognizing these signs of heart problems can help with earlier treatment and better health.

Here are 6 key signs that your heart may not be working properly:

Chest discomfort or pain.

One of the most common signs of heart problems is chest pain, also known as angina. It can feel like pressure, tightness, squeezing, or fullness in the center of the chest. This usually happens when the heart isn't getting enough oxygen-rich blood.

People sometimes ignore this symptom because it is not as dramatic as heart attacks in movies. But if you notice recurring chest pain—especially during exercise or stress and it disappears at rest—see a doctor immediately.

Shortness of breath

If your heart cannot pump enough blood, you may feel short of breath. This can happen when you walk, climb stairs, or even when you are resting or lying down.

Shortness of breath is a common symptom of heart failure, a condition in which the heart weakens and cannot pump blood as well. If you notice this symptom, especially along with chest pain or fatigue, consult a doctor.

Unusual fatigue

Feeling constantly tired, even after getting enough sleep, can be a warning sign. When the heart is not working properly, it does not deliver enough oxygen to the rest of the body, leading to feelings of exhaustion.

This is especially important to watch for in women, who are more likely to experience fatigue as the first sign of heart disease. If you constantly feel tired for no apparent reason, see a specialist.

Swelling in the legs, ankles, and feet

If your legs, ankles, or feet are swollen, the cause may be your heart. A weak heart can lead to fluid buildup in the body, a condition known as edema. Swelling in the lower body is a common symptom of heart failure. If you notice this along with fatigue or shortness of breath, it is important to see a doctor as soon as possible.

Irregular heartbeat

An irregular heartbeat, or arrhythmia, can feel like skipped beats, a racing pulse, or fluttering in the heart.

Sometimes these sensations are harmless, but if they happen often or are new to you, it could be a sign of heart disease. This is especially true if you also feel dizzy or nauseous. Don't ignore an unusual heartbeat.

Dizziness or lightheadedness

Dizziness or lightheadedness may mean that your heart is not sending enough blood to your brain. This could be due to a blockage in your arteries or a problem with one of your heart valves. If dizziness occurs suddenly, especially with chest pain or difficulty breathing, it is time to seek medical attention.

Monitoring these signs can help with early detection of heart problems. Don't wait until it's too late. Regular checkups and paying attention to your body's signals can significantly improve your health. | BGNES
