Introduction: Diabetes Mellitus is a chronic disease that has serious effects on the morbi-mortality. Diabetes type 1 is less prevalent, representing 5–10% of the total cases. Data collected in Africa are scarce, and prevalence and incidence at sub - Saharan Africa are about 3-12/100,000 and 1.1–2.1/100,000 people, respectively. The Angolan reality is not known.

Objective: To show the casuistic of diabetes type 1 obtained from the ambulatory consultation of Endocrinology for the year 2015.

Methods: We performed a retrospective study of the available clinical files in digital and physical support. The diagnosis of type 1 diabetes was according to the diagnostic criteria defined by the WHO. Parameters that have been studied: sex, age, A1c, clinical onset, duration of the disease.

Results: In the year 2015, 1630 patients have been observed at the Endocrinology Ambulatory Service. Only 1539 process were considered for analysis. Among these patients, 1159 (75.3%) were diabetic, being 19 of them (1.63%) type 1 diabetics. The distribution by sex was: 9 (47.4%) men and 10 (52.6%) women. The age spread from 4 to 40 years with a mean of 23 years. Diabetic ketoacidosis (63.11%) was the clinic presentation found at the time of the diagnosis. The time of evolution of the disease varied from 6 months to 15 years of age with an average of 4.6 years. The average glycosylated hemoglobin (HA1c) was 8.86%.

Conclusion: The epidemiology of diabetes is not known, and we cannot advance conclusions from the data collected by our team. Most of the patients observed in endocrinology (75.3%) had the diagnostic of Diabetes Mellitus. The fact that type 1 diabetes is more prevalent among women is in accordance to the international data. It is important to highlight that significant number (63%) of the patients have been diagnosed in the status of diabetes ketoacidosis.
