Cultural and Molecular Factors Predisposed to Non-Alcoholic Fatty Liver Disease and Type 2 Diabetes Mellitus.

There is an exponential increase in the global prevalence of non-alcoholic fatty liver disease (NAFLD) in all populations. The objective of this review is to examine how different cultures and molecular entities influence the progression of NAFLD. Research databases, including PubMed, Scopus, the American Diabetes Association, the American Liver Foundation, and Diabetes UK, were used to retrieve information. Our data analysis showed that cultural norms shape the perceptions of health, illness, and mortality, thus influencing how individuals view themselves and express their experiences and may also affect decisions related to treatment and healthcare. Cultural competence, the ability to understand and navigate cultural differences, is essential for eliciting patient and practitioner perspectives and integrating this understanding into diagnostic and treatment plans. By acknowledging and respecting a patient's cultural background, healthcare providers can foster trust, improve care quality, enhance acceptance of diagnoses, and boost treatment adherence. Although cultural factors play a crucial role in the progression of NAFLD, the disease is also shaped by genetic predispositions, molecular mechanisms, and comorbidities. Molecular pathways involved in the development and progression of NAFLD include alterations in lipid metabolism, insulin signaling, insulin resistance, oxidative stress, defective gut microbiome, and inflammation. This study concludes that a combination of cultural preferences and molecular factors has contributed to the worldwide exponential rise in the prevalence of NAFLD, which in turn has led to an increase in the prevalence of comorbidities such as cardiovascular diseases, diabetes mellitus, and metabolic syndrome.
