When it comes to problems with the lungs, most people immediately think of lung cancer but other respiratory conditions and diseases are just as damaging. Here are seven early warning signs of respiratory problems that can lead to dangerously failing lungs.
1. Cough with increased mucus
Coughing is natural reaction to blocked airways due to irritants such as cigarette smoke or phlegm. When coughs become severe or more frequent than usual with mucus yellow, green or red in color, this may be an early warning sign of respiratory problems.
2. Wheezing and shortness of breath
Low blood oxygen levels usually cause breathlessness as it takes more effort for the lungs to move air in and out. Often times, the shortness of breath is accompanied by wheezing during light physical activity or even when at rest, according to Healthline.
3. Restlessness or difficulty sleeping
Often times, the restlessness and difficulty in sleeping are caused by the shortness of breath experienced at night. Sleep disturbances is definitely a warning sign of a respiratory problem or condition .
4. Morning headaches
Headaches upon waking up in the morning mean inadequate breathing at night, according to Natural News. Low oxygen levels while sleeping can cause a buildup of carbon dioxide in the blood, which can cause a throbbing headache by morning.
5. Swelling feet, ankles and legs
Any swelling in the feet, ankles or legs is linked to problems of the heart or lungs. Fluids tend to build up in the body and often pool in the feet and ankles instead of being expelled.
6. Changes in nails and lips
When a person does not get enough oxygen to the body, a bluish tinge can start around the nail beds and lips known as cyanosis. These changes are signs of low oxygen levels, which is an early warning sign of respiratory problems.
7. Worry
This behavioral symptom may not be as easy to detect but feeling anxious or panicked is an early warning sign of respiratory problems. In most cases, muscles tend to get tense, which makes it even harder to breathe.
