A study of thyroid dysfunction among elderly in a tertiary care hospital

Abstract

Introduction and Aim: The prevalence of thyroid disorders all over the world is on the rise. However, the diagnosis is complicated among the elderlies due to factors such as non-specific clinical manifestations and interacting medications. The aim of the study is to estimate the prevalence and type of thyroid dysfunction among the elderly.
 Materials and Methods: The cross-sectional study was undertaken in the Department of General Medicine of a tertiary care teachinghospital. The study included 100 subjects aged above 60 years, of both genders. Data for clinical examination and biochemical tests such as T3, T4, TSH and lipid profile were collected. Reports of USG/FNAC, performed in cases of thyroid nodule, were also checked.Results:The prevalence of thyroid disorders was 22% of the study population. Overt and subclinical hypothyroidism were observed among 4% and 17% respectively, with 1% having hyperthyroidism. Subclinical hypothyroidism was more common among women. No specific trend was observed with increasing age.TPO antibodies were positive among 73% of the cases. Patients with thyroid dysfunction had higher values of triglycerides, total cholesterol and LDL. The proportion of dyslipidemia was significantly higher among elderly with thyroid dysfunction as compared to people with no thyroid dysfunction (90.90% Vs 24.35%, P value < 0.001).
 Conclusion: Thyroid dysfunction in the elderly is common. Strong clinical suspicion of thyroid diseases in elderly patients presenting with non-specific symptoms is needed. This would aid in the diagnosis of thyroid disorders among the elderly.
