Heart attacks are caused by a lack of blood reaching the heart.
Without enough blood, the heart could become seriously damaged – and it may even be life-threatening.
A heart attack could also be a symptom of coronary heart disease, which is where fatty deposits build up in the arteries, which limits the amount of blood reaching the heart.
You may be at risk of a heart attack if you feel unusually nauseous.
“A heart attack doesn’t just affect your heart — you can actually feel the effects throughout your whole body,” said Penn Medicine.
“Waking up in a cold sweat, feeling nauseated, and vomiting may be symptoms of the flu, but they can also be signs of a silent heart attack.
“You may know what the flu feels like because you’ve had one before, but when your gut is telling you that these flu-like symptoms are something more serious, listen.
“Don’t chalk these symptoms up to the flu, stress, or simply feeling under the weather — they may be much more serious than that.”
But just because you feel nauseous, it doesn’t necessarily mean that you’re having a heart attack.
Most people feel sick at some point in their lifetime, and it may be caused by a variety of different reasons.
Some people develop nausea due to an infection, acid reflux, or even a migraine.
Your nausea is more likely to be caused by a myocardial infarction if it’s accompanied by more common heart attack symptoms.
The most common heart attack signs include severe chest pain, having a radiating pain in your arm, and suddenly feeling very dizzy.
But you can lower your risk of a heart attack by making some small diet or lifestyle changes.
Eating a healthy, balanced diet will lower your chances of fatty deposits in your arteries.
If you think you, or someone you know, may be having a heart attack, it’s crucial that you dial 999 straight away.
