Heart palpitations are often described as an unusual awareness of the heartbeat or a fluttering sensation in the chest. As a medical professional, I can tell you that there are several reasons why you might experience these sensations: 1. Stress and Anxiety: These are common triggers for palpitations. When you're stressed or anxious, your body releases stress hormones that can increase your heart rate. 2. Caffeine, Nicotine, and Alcohol: These substances can stimulate the heart and cause it to beat faster or irregularly. 3. Exercise: Intense physical activity can lead to an increased heart rate, which some people may perceive as palpitations. 4. Dehydration: Lack of fluids can affect your heart's rhythm and potentially cause palpitations. 5. Certain Medications: Some medications, including those for asthma or depression, can have heart palpitations as a side effect. 6. Underlying Health Conditions: Conditions such as anemia, thyroid problems, or heart-related issues can also cause palpitations. It's important to note that while palpitations can be alarming, they are often harmless and resolve on their own. However, if they are frequent, severe, or accompanied by other symptoms like chest pain, shortness of breath, or dizziness, it's crucial to consult with a healthcare provider to rule out any underlying health issues. read more >>
