Abstract: According to the World Health Organization (WHO), the primary component of patient-centered treatment is self-management practices, which serves as the foundation for the management of diabetes mellitus. Purpose: to examine the effect of self- directed management implementation on short-term complications among patients with type II diabetic patients. Design: Quasi Experimental design. Setting: The outpatient medical clinic of Menoufia University Hospital in Egypt. Sampling: A consecutive sample, which included 240 diabetic persons with Type II Diabetes Mellitus, the sample was selected randomly to assign them into of  120 in each group; 120 in control group, while study group was divided into subtype groups (study1 and study2) 60 patient in each group. Instruments: Three instruments used to collect the current data; Instrument (I): Diabetes Mellitus Structured Questionnaire; Instrument (II): Bio physiological measurements. Instrument (III): Patient's self-practices in management. Results: the existing outcomes recorded that; study2, who implemented self- directed management practices with olive oil have been associated with better improvement in all lab investigations as blood glucose 146.33± 25.74, while 167.17 ± 46.28 & 266.94± 63.27 respectively; in study1 and control group; furthermore high density (HDL) in study2  65.90± 2.72 if compared with 62.68 ± 4.04& 65.90± 2.72 respectively; in study1 and control group, also decreasing in low-density lipoprotein (LDL) in study2 than other groups (94.63± 3.31, 96.40 ± 3.35&153.39± 13.99) respectively; highly significance difference among studied groups in short term diabetes complications frequency after application of self-management practices (study2 better than study1&control group). Conclusion: The existing study concluded that implementing of directed self-management practices with olive oil as part of a health dietary plan is likely to produce better Type II Diabetes Mellitus outcomes and reduce short term complications when combined with physical exercise. Recommendation: Replicate the study in another setting and using a larger sample size to generalize the search results. Self- management program can be applied as a hospital routine care for patient with diabetes.
