Pulmonary function in former alcoholics

C Emirgil, B J Sobol

    Chest
    |July 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Former alcoholics often show abnormal lung function, including obstructive issues, particularly women. While some lung function impairments may reverse with sobriety, obstructive changes may persist due to past alcohol consumption.

    Area of Science:

    • Pulmonary Medicine
    • Addiction Research

    Background:

    • Alcoholism is associated with various health issues, including potential pulmonary complications.
    • Understanding the long-term effects of alcohol on lung function is crucial for patient care.

    Purpose of the Study:

    • To evaluate pulmonary function in former alcoholics without other known lung or heart diseases.
    • To investigate the reversibility of alcohol-induced lung function abnormalities with abstinence.

    Main Methods:

    • Pulmonary function tests were conducted on 44 former alcoholics with varying abstinence periods.
    • Participants were members of Alcoholics Anonymous and screened for cardiac or specific pulmonary disease.

    Main Results:

    • 64% exhibited abnormal expiratory flow rates, and 39% had an elevated residual volume to total lung capacity ratio.

  • 16% showed abnormal single-breath diffusing capacity. A high incidence (77%) of obstructive phenomena was noted in women.
  • Abnormalities were not attributed to smoking or prior infections.

    • Conclusions:

    • Past alcohol intake contributes to obstructive lung changes, which may not be reversed by abstinence.
    • Impairment in diffusing capacity appears to be reversible with sustained sobriety.
