5. Nausea, Cold Sweats, Dizziness, or Sudden Weakness
Some heart attack symptoms can feel like the flu, stomach trouble, or a sudden drop in energy. Possible warning signs include nausea, cold sweating, lightheadedness, dizziness, sudden weakness, or feeling faint.
These symptoms are more concerning when they happen suddenly, feel unusual, or appear with chest discomfort, shortness of breath, or pain spreading to the arm, jaw, neck, or back.
The source article warns that sudden unexplained sweating combined with chest discomfort should not be ignored.
Heart Attack Symptoms Can Differ Between Men and Women
Men often report more obvious chest pressure or chest pain, sometimes with left arm discomfort. Women may be more likely to report symptoms such as unusual fatigue, nausea, shortness of breath, jaw pain, or back pain.
Because these symptoms can seem unrelated to the heart, they may be recognized later. That delay can be dangerous.
