Objective: To estimate the level of fibrinogen in patients with type 2 diabetes mellitus.Methods: We conducted a hospital based study of 100 random patients, divided into 4 groups, 25 in each group and compared serum fibrinogen between the group during the study period from November 2019 to April 2021.The patients will be sub classified into four groups:•Patients with type 2 diabetes mellitus without complications (Group – A).•Patients with type 2 diabetes mellitus with microvascular complications (Group – B).•Patients with type 2 diabetes mellitus with macrovascular complications (Group – C).•Patients with type2 diabetes mellitus with both microvascular and macrovascular complications (Group – D).Results: The difference between serum fibrinogen levels among 4 groups were statistically significant (p
