Heart Palpitations
Most of the time, you shouldn’t be aware of your heartbeat. When you do notice it—especially if it feels rapid, fluttering, or irregular—that sensation is called heart palpitations. While palpitations are common, they can be uncomfortable and even alarming.
What Causes Heart Palpitations?
Palpitations can occur for many reasons, ranging from lifestyle factors to medical conditions. Some of the most common causes include:
-
Physical activity: Exercising, fast walking, running, or cycling can make your heart beat faster.
-
Anemia: Low red blood cell levels can make your heart work harder.
-
Pregnancy: Hormonal and circulatory changes may trigger palpitations.
-
Medications: Certain drugs, including stimulants or asthma medicines, can affect heart rhythm.
-
Thyroid problems: Overactive or underactive thyroid can lead to abnormal heartbeats.
-
Arrhythmias: Irregular heart rhythms can make your heart flutter or skip beats.
-
Heart disease: Underlying heart conditions may increase palpitations.
-
Substance use: Caffeine, alcohol, nicotine, or recreational drugs can trigger palpitations.
-
Stress and mental health: Anxiety, depression, and panic attacks often manifest as awareness of the heartbeat.
When to Seek Medical Advice
Most palpitations are harmless, but if they are frequent, prolonged, or accompanied by chest pain, dizziness, or shortness of breath, it’s important to see a healthcare professional.
