Background:
Thyroid dysfunction is frequent in adult outpatient practice and may coexist with major metabolic abnormalities.
Objective:
To assess the pattern of thyroid dysfunction and its association with metabolic parameters among adults attending a General Medicine clinic.
Methods:
This cross-sectional observational study included 100 adults attending the General Medicine clinic at Government Medical College, Nizamabad, Telangana, India, from January to December 2025. Demographic details, anthropometry, thyroid profile, fasting plasma glucose, HbA1c, and lipid profile were recorded. Participants were classified as euthyroid or having thyroid dysfunction. Metabolic parameters were compared using the independent t-test and chi-square test.
Results:
The mean age was 43.8 ± 12.6 years, and 58.0% were females. Thyroid dysfunction was observed in 38.0%; subclinical hypothyroidism was most common (20.0%), followed by overt hypothyroidism (10.0%), subclinical hyperthyroidism (5.0%), and overt hyperthyroidism (3.0%). Thyroid dysfunction was more frequent among females than males (46.6% vs. 26.2%; χ²=4.28, p=0.039). Compared with euthyroid adults, those with thyroid dysfunction had higher BMI (28.1 ± 4.5 vs. 25.3 ± 3.8 kg/m², p=0.002), waist circumference (94.2 ± 11.1 vs. 86.8 ± 9.6 cm, p=0.001), HbA1c (6.5 ± 1.1% vs. 5.9 ± 0.8%, p=0.006), total cholesterol (207.8 ± 42.5 vs. 178.4 ± 34.6 mg/dL, p<0.001), triglycerides (181.9 ± 61.8 vs. 142.6 ± 52.4 mg/dL, p=0.001), and LDL cholesterol (130.6 ± 35.4 vs. 104.8 ± 28.7 mg/dL, p<0.001). Metabolic syndrome was more frequent with thyroid dysfunction (60.5% vs. 24.2%; χ²=13.20, p<0.001).
Conclusion:
Thyroid dysfunction, mainly subclinical hypothyroidism, was common and significantly associated with adverse metabolic parameters.
Recommendations:
Thyroid screening should be considered in adults with obesity, dysglycemia, dyslipidemia, or metabolic syndrome.
