Learn to recognize the early, subtle signs of Congestive Heart Failure (CHF), a condition affecting millions in the U.S. Key symptoms include progressive shortness of breath, especially during activity or when lying down, and persistent swelling in the ankles and feet. Overwhelming fatigue, a persistent cough, and unexplained rapid weight gain from fluid retention are also major red flags. Be aware of changes in heart rhythm, increased nighttime urination, and subtle cognitive shifts like confusion. These symptoms often appear gradually and worsen over time, forming a pattern that should not be ignored. Understanding your personal risk factors, such as high blood pressure or a history of heart disease, is crucial. Early medical evaluation is essential for effective management and to preserve your long-term health and quality of life.
