Diabetes is a chronic illness that occurs when the pancreas stops producing insulin or when the body cannot use the produced insulin. Insulin is a hormone produced by the pancreas that helps glucose from meals enters the body's cells for energy. The overall goal is to assess diabetes patients' knowledge, attitudes, and behaviors about prevalent diabetic complications. This research used a descriptive qualitative methodology to assess diabetes complication knowledge, attitude, and practice. Ninety-eight diabetic patients were visiting the Egyptian Hospital in Mogadishu for four weeks. The data was collected using questionnaires. Finally, SPSS 20 was utilized for analysis. The research was performed from May to July 2020 with a non-probability sample size of 98 diabetics. The bulk of responders were aged 40 -60 (36.7%). Type 2 was the most common (47.96%). 44.9% of respondents had diabetes for more than ten years. 60.2% had regular checkups, and 54.1 percent had therapy. 52% of participants were on a diet. 63.3% of respondents do not exercise often. However, most responders know the common issues (75%). Less than half of those polled had problems (41.8%). 22% incidence of Diabetic ketoacidosis. 78.6% of respondents know variables that decrease diabetes complications, whereas 22.4% do not. 37.8% of respondents saw a doctor for diabetes problems, whereas 62.2% did not. Diabetic patients' knowledge, attitude, and practice were satisfactory for fundamental illness entanglements and self-testing. These findings may also be due to patient notification and, therefore, long-term illness that leads them to get acquainted with things alone.
