I have A1AT deficiency. Can lifestyle changes help my lungs?

Question

Hello doctor,

I am 35, recently diagnosed with alpha-1 antitrypsin deficiency after my spirometry showed FEV1 at 55 % predicted. My serum A1AT levels are 52 mg/dL, and genetic testing revealed a ZZ phenotype. I have had chronic shortness of breath and mild wheezing for the past year.

My doctor suggested augmentation therapy, but I am concerned about its effectiveness and whether it slows disease progression. So, I need your opinion on the following -

Are there any lifestyle changes or inhaler therapies that can improve lung function?
Also, should my family get screened since this is hereditary?

I want to understand the long-term outlook and whether early treatment can prevent severe COPD or liver problems.

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Since you have alpha-1 antitrypsin deficiency with the ZZ type (Z allele homozygous), your risk of developing lung problems like COPD (chronic obstructive pulmonary disease) and also the chances of getting liver disease are higher, so regular monitoring is important.

Augmentation therapy can help by slowing down the worsening of lung function, but it will not reverse the damage that has already happened, which is concerning. Based on your concern about using inhalers, bronchodilators, or steroid sprays may help control symptoms like wheezing and shortness of breath, though they do not change the underlying condition. So lifestyle choices make a big difference.

I suggest you follow these tips for a better outcome -

Completely avoiding smoking and going to polluted environments.
Keeping up with vaccines.
Exercising within your limits
Maintaining good nutrition.

Because this condition runs in families, your close relatives should be tested to see if they also carry the gene. The long-term outlook depends on how early it is managed, but starting treatment and follow-up now can help slow the disease and reduce the chance of severe lung or liver problems in the future.

I hope this helps you. Always feel free to reach out to me at any time. I am always here to help.

Thank you and take care.
