Hello, the color of your phlegm can provide clues about underlying health conditions. If you notice pink-tinged sputum accompanied by shortness of breath or rapid breathing, this may indicate a pulmonary issue. Green-colored sputum often suggests bronchial pathology, such as bronchitis, bronchiectasis, or infection. We hope this information is helpful to you. Wishing you good health and happiness!
