Abstract:
Diabetes Mellitus and Thyroid Disorder, both are the most common endocrine
diseases to be familiar in clinical practice. Thyroid hormones are involved in all the
metabolic pathways including carbohydrate metabolism. On the other hand, there are
variable degrees of glucose production, insulin secretion and insulin resistance. Hence there
is imbalance in carbohydrate metabolism particularly, in both Type 2 DM and Thyroid
Disorder. Diabetes Mellitus is responsible for large number of deaths worldwide and
Diabetic Patients are at risk of having other autoimmune diseases including thyroid
abnormalities. Both type 2 diabetes and hypothyroidism are highly prevalent disorders in
the community. Since the thyroid hormones are involved in regulation of carbohydrate
metabolism, it is expected that their abnormal levels would disrupt carbohydrate
homeostasis. Thyroid hormones are significant regulators of glucose metabolism. In Type 2
DM, the most common type of thyroid dysfunction is hypothyroidism that’s why the aim of
this study to investigate the relationship between serum thyroid profile and glycemic
variability in Type 2 diabetic patients and compare the TSH levels in type 2 diabetic
patients and non-diabetic subjects. The study type was case control, conducted at National
medical center in Karachi, Pakistan from October 2022 to May 2023. A total of 144
subjects were selected, out of which 72 patients were diagnosed with type 2 diabetes
mellitus and 72 were non-diabetic volunteers in the study. Diabetic status and its severity
will evaluate by fasting and random blood sugar and hba1c while thyroid function test was
done by analyzing serum levels of thyroid profile and then compare in both cases and
control. Significant increase in thyroid-stimulating hormone concentration can be another
risk factor for the progression of type 2 diabetes mellitus with unknown thyroid status and
there is high prevalence of subclinical hypothyroidism among type 2 diabetes patient
compared to non-diabetic subjects. This study shows the thyroid dysfunction in type 2
diabetes mellitus signifying that the thyroid condition gets worse with diabetic severity. On
assessment of thyroid dysfunction in type 2 diabetes mellitus patients shows large
variations amongst different strategies, the quality of life and morbidity in type 2 diabetic
patients can be improved in this way
