*Sheme ZA,1 Huda AK,2 Akhter L3
Abstract
Background: Diabetes mellitus (DM) and thyroid dysfunction are two of the most prevalent endocrine disorders that frequently coexist. Both conditions share several pathophysiological pathways that may influence each other’s progression and management.
Objectives: To analyze the relationship between thyroid stimulating hormone (TSH) levels and glycemic control in patients with type 2 diabetes mellitus (T2DM).
Methods: This cross-sectional analytical study included 50 diabetic patients attending the Department of Medicine, Rangpur Medical College Hospital, between January 2024 to December 2024. Demographic data, fasting blood sugar (FBS), HbA1c, and serum TSH levels are recorded.
Results: Among 50 patients (28 males, 22 females; mean age 52.3 ± 9.4 years), 34% had abnormal TSH levels. Hypothyroidism was more common (26%) than hyperthyroidism (8%). Poor glycemic control (HbA1c > 8%) was significantly associated with elevated TSH (p < 0.05).
Conclusion: Subclinical hypothyroidism is frequent among T2DM patients and correlates with poor glycemic control. Routine screening for thyroid dysfunction is recommended for better management of diabetic patients.
