Unexplained Shortness of Breath
Shortness of breath is a classic sign that your heart is facing difficulties. The inadequate blood circulation of a weak heart results in fluid accumulation in your lungs. You will experience breathing difficulties when you walk or climb stairs, and during other everyday activities. At night, you might experience sudden gasping episodes, or you may need to sleep with extra pillows because lying flat causes breathing issues.
Constant Fatigue and Weakness
Endless tiredness which persists even after resting serves as an indication that your heart function is weak. The inadequate delivery of oxygen-rich blood from your heart to your body’s organs and muscles creates both exhaustion and weakness. The process of climbing stairs or carrying groceries now requires excessive effort that exceeds your previous abilities.
Swelling in Legs, Ankles, or Feet
A failing heart fails to efficiently pump blood, which results in fluid accumulation throughout the body. Edema appears as swelling throughout the body, with increased prominence in the feet, ankles, and legs. The swelling in your legs becomes more noticeable after periods of standing or sitting and produces discomfort along with a heavy sensation in your lower extremities.
Dizziness, Lightheadedness, or Fainting
The heart’s poor blood pumping function causes your brain to receive reduced oxygen supply. The insufficient oxygen supply to your brain can lead to dizziness, lightheadedness, or fainting. Your body feels weak along with confusion and shakiness, particularly when you get up from rest or finish any physical activity.
Irregular or Fast Heartbeat
The pattern of heart rhythms reveals valuable information about heart wellness. A weak heart tends to develop irregular heart rhythms (arrhythmia) or abnormal fast heart rates. The irregular heart rhythm produces skipped beats which create fluttering and pounding sensations inside your chest, despite the absence of pain.
