At 35, can smoking worsen my alpha-1 antitrypsin deficiency?

Question

Hello, Doctor,

I am 35 years old female. I have been recently diagnosed with alpha-1 antitrypsin deficiency after years of being told my breathing issues were only asthma-related. Looking back, symptoms seemed mild for a long time and then became more obvious in my thirties. I am confused why a genetic condition present since birth would start causing noticeable problems later instead of much earlier. Please tell me,

Why does adult-onset alpha-1 often begin showing symptoms around age 35 or beyond?
Does smoking or environmental exposure accelerate when the disease appears?
Can earlier diagnosis actually slow progression through better management?

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

The thing is, the absence of the enzyme alpha 1 antitrypsin exposes the lungs to damage from many harmful factors, including

Infections.
Allergens.
Pollution.
Smoke.

For some time, the body can compensate for this deficiency, but there is a limit to how much protection it can provide.

This disease is usually progressive rather than sudden. Early on, the lungs still have some ability to cope with the deficiency, but later, when the damage exceeds a certain level, it becomes irreversible, and the body starts showing symptoms.

Important factors that worsen lung damage include:

Smoking, which is one of the biggest co factors and, greatly increases airway damage.
Secondhand smoke, which can also be very dangerous.
Air pollution and environmental irritants may severely affect the airways.

Diagnosis is often delayed because many patients are mistakenly diagnosed with asthma, and there may also be inadequate awareness among some physicians. However, if the diagnosis is made early, it can help significantly because patients may benefit from specific treatment such as augmentation therapy.

I hope this information helps you.

Feel free to ask further queries.

Thank you.
