Early signs of heart failure can be subtle and are often overlooked. Symptoms such as unusual fatigue, shortness of breath during routine activities, sudden weight gain, or waking up at night gasping for air may be warning signs. A simple at-home test, where a dent remains in swollen skin after gentle pressure for several seconds, can indicate fluid retention known as pitting edema. While swelling can result from various causes, persistent or worsening symptoms, especially when combined with other signs, should prompt a medical evaluation. Early recognition and consultation with a doctor are crucial for timely diagnosis and effective treatment.
