Health experts warn of cardiovascular and respiratory warning signs

Medical professionals are highlighting specific physical symptoms that may serve as early indicators of heart or lung disease.

According to cardiologists, changes in the lower extremities can signal circulatory issues. Because the legs are the furthest part of the body from the heart, symptoms such as swelling, pain, skin discoloration, or cold feet may appear when the cardiovascular system struggles to deliver oxygenated blood efficiently. Gravity complicates this process, as the heart must work harder to return blood from the legs.

Additionally, shortness of breath during physical exertion, such as climbing stairs, can be a significant warning sign. While often attributed to aging or poor fitness, sudden or worsening breathlessness may indicate underlying conditions including heart failure, coronary artery disease, arrhythmia, asthma, or chronic obstructive pulmonary disease (COPD). Experts advise seeking medical attention if these symptoms are new or worsening.
