Persistent Cough and Sudden Shortness of Breath: Causes, Warning Signs, Treatment, and Prevention
Introduction
Respiratory diseases are among the most common health problems worldwide and include symptoms such as persistent cough and sudden shortness of breath. Although these symptoms may seem simple at first, they can sometimes indicate serious conditions affecting the lungs, heart, or respiratory system.
Many people tend to ignore cough or breathing difficulties, assuming they are temporary, which can delay the diagnosis of serious conditions such as asthma, pneumonia, or pulmonary embolism.
What is the Respiratory System?
The respiratory system is responsible for delivering oxygen to the body and removing carbon dioxide. It consists of:
Nose
Pharynx and larynx
Trachea
Bronchi
Lungs
Any dysfunction in these parts may lead to symptoms such as coughing, shortness of breath, or chest pain.
