Heart attacks often seem to happen suddenly, but in many cases the body gives warning signs weeks before the event occurs. Surprisingly, some of these signals may appear in your feet.
Your circulatory system plays a major role in heart health, and when the heart is struggling, blood flow throughout the body can be affected. Because the feet are farthest from the heart, they can sometimes reveal early clues that something isn’t right.
Here are six possible signs your feet may show weeks before a heart attack.
1. Swelling in the Feet or Ankles
Swelling in the feet and ankles, also known as edema, can occur when the heart has difficulty pumping blood efficiently. This causes fluid to accumulate in the lower parts of the body.
If swelling appears suddenly or becomes persistent, it may be worth discussing with a doctor.
2. Cold Feet
Poor circulation can cause your feet to feel unusually cold even when the rest of your body feels normal.
When blood flow is reduced, the extremities like feet and toes may become colder than usual.
