Hi,
There are several potential causes for a racing heart and nausea, including:
* Anxiety or stress: These emotions can cause physical symptoms such as
rapid heart rate, nausea, and a
metallic taste in the mouth.
* Medication side effects: Some medications, including cold medications like DayQuil, can cause side effects like a racing heart and nausea.
*
Hormonal imbalances: Changes in hormone levels, such as those that occur during
pregnancy or due to thyroid problems, can cause physical symptoms.
* Dehydration: Not drinking enough water can cause a variety of symptoms, including a racing heart and nausea.
* Heart problems: Certain heart conditions, such as arrhythmias or
heart disease, can cause a racing heart and other symptoms.
It's important to see a doctor if you are experiencing these symptoms regularly or if they are severe. Some tests may be needed to rule out underlying medical conditions. They may also ask about your medical history, lifestyle, and any medications you are taking to determine the cause of your symptoms.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
