Diabetes mellitus, sometimes called “sugar disease”, has grown into a major public health
problem in Nigeria, especially in places where people’s cultural ideas about illness shape how
they think about disease and what they do for treatment. This study basically described how
diabetes is explained and how these explanations relate to diet compliance among residents of
Bayelsa State, Nigeria. In particular, the study focused on local understandings of the aetiology
and nature of diabetes, and explored the ways in which local understandings of diabetes impact
upon the perception of medical advice and diet adherence, as well as the difficulties
encountered by diabetes patients as they juggle local dietary practices and medical advice. The
Health Belief Model (HBM) was used as the guiding theoretical framework. In terms of design,
the study used a descriptive survey approach. The study population involved diabetes patients,
diabetes care takers, healthcare workers, nutritionists, traditional healers, and community
elders in the area. A total sample size of 400 respondents was arrived at using Taro Yamane’s
formula. A multi-stage sampling process that basically used random, cluster, systematic and
purposive sampling was also taken to select Oporoma, Peremabiri, Aleibiri, Eniwari, Kaiama
and Okoloba communities. Structured questionnaires were employed to collect primary data,
while descriptive statistics such as frequencies, percentages, mean scores, as well as tables
and charts were used to analysed the data. The findings suggested that diabetes is strongly
influenced by cultural beliefs. This is because many respondents linked diabetes to too much
sugar intake, spiritual attacks, and hereditary causes. The study further showed that the
traditional explanation of diabetes has a meaningful effect on how patients view medical
guidance and whether they stick with dietetic practices. In fact, some patients chose herbal,
spiritual remedies over hospital-based care. The study highlighted the need for increased
public health education, culturally appropriate health interventions, and cost-effective dietary
support programs to help patients manage their diabetes and adhere to dietary guidelines.
