An 18-year-old male who does not smoke has a carbon monoxide level of 7 in the lungs. What should be done?

Hello, doctor.
I am currently an 18-year-old male, non-smoker, non-drinker, and have no history of tuberculosis.
During a university health check, I underwent a carbon monoxide test for my lungs using a handheld device with a digital display.
The values before blowing into the device were all normal (1-3) for a non-smoker.
However, my result was 7, which seems to fall into the moderate smoking range.
Should I be concerned about any underlying disease? I am quite anxious and would like to know if I need to seek immediate medical attention.
Thank you, doctor.

More Info

Based on the information provided, it appears that you are an 18-year-old male who does not smoke or drink alcohol and has no history of lung diseases such as tuberculosis. You recently underwent a carbon monoxide (CO) test during a university health check-up, which showed a level of 7 parts per million (ppm). You are understandably concerned about this result, especially since it seems to fall into a range that could indicate moderate smoking habits, according to the chart you referenced.

Firstly, it is important to clarify that a CO level of 7 ppm is generally considered to be on the lower end of the spectrum for non-smokers. The typical range for non-smokers is indeed between 1-3 ppm, but levels can fluctuate due to various factors. Environmental exposure, such as being in a car with heavy traffic, being near industrial emissions, or even exposure to secondhand smoke, can elevate CO levels temporarily. Additionally, physical exertion can also lead to increased CO levels in the bloodstream.

Given that you do not smoke and have no significant health issues, it is unlikely that a CO level of 7 ppm is indicative of a serious health problem. However, it is always wise to monitor your health and be aware of any symptoms that may arise. If you experience any respiratory issues, persistent cough, or other concerning symptoms, it would be prudent to consult a healthcare professional for further evaluation.

In terms of immediate action, there is no need for alarm. The recommendation would be to follow up with your healthcare provider for a routine check-up, especially if you have any ongoing concerns or symptoms. They may suggest retesting your CO levels or conducting additional assessments to ensure that there are no underlying issues.

Moreover, if you are feeling anxious about your health, it might be beneficial to discuss these feelings with a healthcare professional. Anxiety can often exacerbate concerns about health, and having a clear understanding of your situation can help alleviate some of that stress.

In summary, while a CO level of 7 ppm is higher than the typical range for non-smokers, it is not necessarily a cause for immediate concern, especially given your non-smoking status and lack of significant health issues. It is advisable to monitor your health and consult with a healthcare provider if you have any further questions or if symptoms develop. Remember, maintaining a healthy lifestyle, including regular exercise and a balanced diet, can also contribute positively to your overall well-being.
