Chronic illnesses such as diabetes, high blood pressure, and heart disease are becoming increasingly common among older adults in Oman, affecting their health, mobility, and independence. Managing these conditions requires taking medications regularly, eating healthy foods, and staying physically active. However, many older adults face challenges such as limited access to healthcare, medication shortages, and a lack of practical health education. This study explored how older Omani adults manage chronic illnesses in their daily lives and what helps or hinders their efforts. Through interviews with 19 participants, the study found that family support, religious faith, and guidance from healthcare professionals play a vital role in helping older adults maintain healthy routines. Yet many also struggle with long clinic wait times, transportation difficulties, and cultural expectations that sometimes conflict with medical advice. For example, some felt social pressure to eat traditional foods that were not suitable for their condition, while others depended on family members for transportation because public transport was limited. Improving self-management requires collaboration between healthcare providers, policymakers, and families to make healthcare more accessible and health education more practical. Encouraging the use of simple, user-friendly digital tools could also help older adults track medications and monitor their health. By addressing these barriers and empowering older adults with appropriate support, Oman and the wider GCC region can foster healthier, more independent aging and reduce the burden of chronic illness.
