Health Queries

My heartbeat is faster than normal when I go to sleep at night, what medicine should I take for this?

G.santoshini Reddy

M Pharmacy (Pharmaceutics)

Experiencing a fast heartbeat at night (palpitations) can be concerning, but you should not take any medication without a proper medical evaluation. Self-medicating can be dangerous. This symptom can be caused by simple things like stress, anxiety, caffeine, dehydration, or hormonal changes, but it can also indicate underlying heart or thyroid issues. I highly recommend consulting a doctor. They may perform an ECG or recommend a heart monitor to find the exact cause and prescribe the correct treatment, such as beta-blockers, if necessary. Meanwhile, avoid caffeine, alcohol, and heavy meals before bed, and practice deep breathing to help calm your heart.

My heart starts beating very fast when I think about my past or worry about the future, even though my blood pressure is usually normal. Is this something serious, and how can I manage it?

Vikas Singh

M Pharmacy

A fast heartbeat when thinking about the past or future is often due to anxiety or stress triggering your body?s response, even if your blood pressure is normal. Try simple calming methods like slow deep breathing or grounding yourself in the present moment when it starts, and keep a routine with proper sleep and light daily activity to stabilise your body. Reducing tea, coffee, and long screen time can also help, and sharing your thoughts with someone you trust may ease the mental load. Practising short relaxation or mindfulness exercises daily can make these episodes less frequent. If episodes become more intense, more frequent, or accompanied by dizziness or chest discomfort, consult a doctor to assess and guide you in managing them effectively.

I have been getting short episodes of increased heartbeat for the past six months. Is this serious, and how can I manage it?

Vikas Singh

M Pharmacy

Short episodes of rapid heartbeat over months are often due to palpitations caused by stress, caffeine, poor sleep, or minor rhythm changes. Try reducing tea, coffee, and energy drinks, and keep a regular sleep routine so your heart rhythm stays stable, and practise simple relaxation like slow breathing to calm the body during episodes. Stay well hydrated and avoid skipping meals, as this can trigger palpitations; include light daily activity, like walking, to support heart health. Try to note when these episodes happen and what you were doing at the time. If you experience chest pain, dizziness, or fainting, seek medical attention. Consult a doctor to check the cause and guide proper care.
