Background: Neuropathic pain (NP) is one of the most common complications of type 2 diabetes mellitus (DM). The frequency of NP in population living with type 2 DM is unclear. Objective: To determine the frequency of NP symptoms in patients with type 2 DM. Materials and Methods: This cross-sectional study recruited 250 type 2 DM patients attending the outpatient diabetes clinic of the Lagos University Teaching Hospital (LUTH) over a period of 4 weeks. Demographic data and data regarding current DM treatment, prior diagnosis of NP, and current treatment of NP were obtained using a structured questionnaire. Glycaemic status of the patients was assessed measuring fasting blood glucose and glycosylated hemoglobin level. Presence of NP was documented using the painDETECT questionnaire (PDQ). Results: NP was present in 54 out of the 250 type 2 DM patients studied giving a frequency of  21.6%. Out of 54 patients 36 (66.7%) were females and 18 (33.3%) were males giving a male: female ratio of 1:2 (P < 0.05). The mean age of type 2 DM patients with NP was significantly higher than the mean age of type 2 DM patients without NP (62.4 ± 10.9 years vs 58.9 ± 11.7 years; P = 0.05). Glycaemic status and disease duration did not differ among DM patients with or without NP. Only 10 out of 54 (18.5%) patients were treatment naοve at the time of study; however, out of the 44 patients receiving treatment only 9 (20.5%) were on appropriate treatment compared to international guidelines on treatment of diabetic NP. Conclusion: NP was present in 21.6% of type 2 DM patients attending the LUTH.
