Some of the other signs are quieter, but can warn you sometimes days before the attack.
Feeling tired for no apparent reason can be an early warning signal of an impending attack.
If you’re feeling unexplainable fatigue, or have a general sense of just not feeling “right,” these can be warnings from your body that something is wrong.
If this feeling goes on for more than one day, and there’s no illness or other visible reason for it, you should be checked out by your doctor.
This is especially true if you have any known risks for heart attack.
Of course, you should also consult a doctor if you have a history of heart attacks in your family.
Even if it turns out that you’re just run down from stress, knowing for sure can lessen overall stress and help prevent stress from triggering an attack.
The primary cause of non-illness related fatigue is actually your diet and exercise habit. If you know you aren’t 100% on point in these areas, that’s something else you should consider.
