To study and compare the spirometric changes in patients with subclinical hypothyroid with euthyroid controls.
Thirty diagnosed cases (3 male, 27 female with mean age of 40 ± 7 years) of subclinical hypothyroidism (SCH) and thirty age and sex matched healthy controls underwent spirometry test in order to determine if respiratory functions are effected or not. Medical history, physical examination, blood pressure on two different occasion and chest radiogram were performed for all participants. The data of two groups was compared.
The characteristics of SCH patients and control cases were similar with regard to age, sex, and body mass index (BMI). Serum thyroid stimulating hormone levels (TSH) were significantly higher in SCH patients than the controls (P < 0.001). There is a significant reduction of spirometric function in all Schs patients when compared to control subjects.
The present study highlights the importance of spirometry test in patients of subclinical hypothyroidism, as an important diagnostic procedure to screen asymptomatic patients for potential respiratory abnormality.
