Evaluation of Pulmonary Functions in Patients with Hypothyroidism Who Are on Conservative Management
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2014, Vol 2, Issue 2
Abstract
Hypothyroidism is a state in which the thyroid gland does not produce enoughamountsof the thyroid hormonessuch as thyroxine (T4) and triiodothyronine (T3).Iodine deficiency is often cited as the most common cause of hypothyroidism worldwide but it can be caused by many other factors. It can result the lack of activity of thyroid gland or from iodine-131 treatment, and can also be associated with increased stress. Aim of the Study was to Determine the Pulmonary Function Test parameters and Efficiency of lung Performances among the hypothyroidism Subjects. A total number of 40 patients with clinical hypothyroidism (n=20) group I and (n=20) group II healthy subjects without pre and past history of hypothyroidism served as a control group. Pulmonary functions test were evaluated byusing simplespirometer. Pulmonary Function Test parameters such as FVC, FVC%, FEV1, FEV1%, FEV1/FVC, FEF25-75, FEF25-75%, were assessed. Biochemical parameters such as free triiodothyronine (FT3), free thyroxin (FT4) and thyroid stimulating hormone (TSH) levels were measured in all subjects to know the hypothyroidism state among the subjects of both the groups. From our study we concluded that the pulmonary function test parameters showed a lesser value in hypothyroidism group I when compared to normal subjects group II. Spirometer evaluation of the respiratory function revealed significantly lower values for FVC (L) P<0.05, FVC (%); P<0.05, FEV1 (L) P<0.05 and FEV1 (%) P<0.05. Hypothyroidism affects the respiratory system, which in turn reduces the efficiency of respiratory system. Regular monitoring of pulmonary function test among the subjects may rule out the possible outcomes among the hypothyroidism subjects who are on regular therapy.
