Diabetes is a significant public health problem and one of the causes of death and disability globally. One of the main problems with diabetes control is the lack of adherence to therapeutic regimens in people with diabetes. This study investigates the experiences and views of the Iranian people with diabetes to identify the challenges of the process of adherence to treatment.

A grounded theory research design was used, incorporating in-depth interviews to collect the data. Using purposeful sampling, 28 people with type 2 diabetes (9 men, 19 women) from different places were included in the study. Constant comparative analysis was undertaken to identify key categories.

The main challenge in this process is losing the golden time of preventing the complications of the disease that occurs for the following reasons: cultural habits and values, religious beliefs (believing diabetes was God’s will), resistance to change due to age, job conditions, lack of harmony in the family, and non-shared decision-making in the health system.

People with diabetes go through trial and error in order to achieve awareness and insight, and consequently, adherence to treatment. Therefore, they need help and support to achieve insight and adherence to treatment faster and without complications. In fact, if the care plan is designed to encourage active patient participation by the treatment team in the shortest possible time, the time to achieve compliance will be shorter and will have the least side effects for these people.
