7 Signs That May Indicate Your Heart Needs Urgent Attention

For example, you may find yourself struggling to:

• Walk your normal route
• Carry groceries
• Climb stairs
• Complete household tasks
• Exercise at your usual levelp

You may also feel exhausted even after getting enough sleep.

Fatigue has countless possible causes, including poor sleep, stress, infections, anemia, thyroid disorders, medication effects, and many other conditions.

Nevertheless, new and unexplained fatigue combined with breathlessness, chest discomfort, dizziness, or reduced exercise tolerance deserves medical evaluation.

5. Dizziness, Fainting, or Feeling Like You Might Pass Out

Your brain needs a continuous supply of blood and oxygen.

If blood pressure drops significantly or the heart rhythm becomes abnormal, you may experience dizziness or feel as though you’re about to faint.

Some people actually lose consciousness.

Occasional lightheadedness can have relatively simple explanations, such as dehydration or standing up too quickly. But unexplained fainting—particularly during exercise or when accompanied by chest pain or heart palpitations—should never be casually dismissed.
