Have you ever experienced breathlessness even after carrying out your day-to-day activities? Or have you been frequently experiencing wheezing or coughing fits? If your answer to either of the questions is yes, you might want to get yourself checked out. These can be considered signs of weak lungs that aren’t functioning optimally. Lungs have a crucial role to play in purifying the blood and supplying the body with oxygen.

Shortness of breath
Breathing difficulty or shortness of breath is among the most common signs of poor lung health. This does not mean calling the doctor’s clinic after you have run a marathon. But, if a short brisk walk or climbing a flight of stairs leaves you breathless, it could be a red flag you need to pay attention to. This sign could indicate conditions like asthma, chronic obstructive pulmonary disease, or lung cancer.

Chronic cough
Some infections or flu can leave you with a cough that lasts weeks after the fever has abated. However, a chronic cough that has managed to stick around for more than eight weeks can be a sign you need to see a doctor. It could indicate underlying conditions such as asthma, COPD, tuberculosis, or lung cancer. If left untreated, it could be a cause for concern and may lead to the development of further complications.

Wheezing
Ever noticed the high-pitched whistling-like sound you sometimes make when breathing? That is wheezing. This happens when the airways narrow down due to allergies, COPD, or asthma. Occasional wheezing isn’t necessarily a concern. However, frequent and prolonged wheezing should be considered a sign of some underlying condition.

Blue lips
Everyone knows that blue lips are not something you take lightly. Blue lips or fingernails indicate a lack of oxygen. This could be because of some obstruction or poor lung function. This is also something that should not be overlooked. If you come across anyone with blue fingernails or lips, make sure they are taken to the doctor immediately. It could be an indication of a serious underlying condition.

Fatigue
Fatigue is a symptom that can be associated with numerous health conditions. Some as common as the flu and as serious as cancer can all lead to the patient being fatigued. Poor lung health is also one of these conditions. If your fatigue is coupled with other symptoms like shortness of breath, consult a doctor about underlying conditions like COPD or other infections.

Difficulty exercising
If any kind of physical activity ends up making you feel out of breath, it might be a red flag indicating poor lung health. The compromised lungs could be a sign of underlying health concerns like asthma and COPD. If you experience breathlessness or other exercise issues, you might want to consult a doctor.

Frequent infections
Frequently contracting lung infections is yet another sign of poor lung function. It can further weaken the lungs and other organs of the respiratory system. This could be a result of tuberculosis, bronchitis, or pneumonia. The infections can cause greater harm in the long run if left untreated.
