With the increasing cases of heart attacks, it has become essential to know more about the warning signs your body gives before something major happens. It is therefore important to stay alert to anything that seems off from your routine, such as extreme tiredness, unrest, poor sleep, and more.

5 warning signs your heart needs attention

Shortness of breath


When normal activities cause unusual breathlessness, consider it a sign. Your body may not be pumping oxygen as well as it should. “Breathing heavily while climbing stairs, walking, or even lying down? Your heart may be struggling to circulate oxygen efficiently.”

Unusual fatigue


Excessive tiredness even after waking up and during routine tasks should not be treated lightly. “Feeling tired even after resting? If daily tasks suddenly feel exhausting, your heart may not be pumping efficiently enough, causing low energy levels.”

Irregular heartbeats


An irregular heartbeat can indicate an underlying problem, especially when accompanied with other symptoms. “Skipping beats, fluttering, pounding, or sudden changes in rhythm? These subtle changes can sometimes signal underlying heart stress.”

Poor sleep or restlessness


Disturbed sleep does more harm than you can imagine, and if it becomes a pattern, then it’s best to seek medical attention. “Waking up frequently, gasping for air, or struggling to sleep flat can also be linked to cardiovascular strain.”

Swelling in feet or ankles


When your heart struggles to pump blood, it can cause fluid buildup in the legs and lead to swelling. “Fluid retention in the ankles, feet, or legs can indicate that the heart is not circulating blood well, leading to fluid buildup.”
