This study assessed the constraints that militate against the wellness seeking behavior among adults in Abia and Imo States, Nigeria. The study employed a descriptive survey design using a quantitative approach, targeted at adults who were recruited through multistage and simple random sampling across Abia and Imo States in Nigeria. A semi-structured questionnaire was used to collect data. Descriptive statistics were used, and linear regression model was used to test for associated factors while t-test and z-test were used to test for significant differences between the two states. All data analysis were done at 5% level of significance. The study revealed that the main constraints to wellness seeking behavior were financial problems, dislike of modern medicine, large family size; belief of not getting sick, being too young, and wellness activities are unnecessary. Hence, it was concluded that there is a need for targeted public health interventions. These interventions should focus on improving access to health facilities and resources and addressing the competing demands that limit engagement in wellness activities in Nigeria.
