Ramadan fasting and liver diseases: A review with practice advices and recommendations

Abstract

Ramadan fasting is obligatory for Muslim healthy adults. However, there are many exemptions from fasting; including patients, whose diseases will be aggravated by fasting. Muslim patients with different liver diseases are frequently seen in the clinics discussing their intent to fast this month with their treating physicians. To answer our patients’ inquiries about the expected benefits and/or risks of fasting and delivering them the best care, we carried out this review and we draw advices and recommendations based on the available evidence. A web-based search, combining multiple keywords representing different liver diseases with Ramadan fasting had been carried out. To answer the research question: Do adult Muslim patients with different liver diseases who fast the month of Ramadan have had a deleterious effect on their health in comparison to those who did not fast? Relevant publications were retrieved. No randomized controlled trials were focusing on Ramadan fasting and liver diseases in the filtered databases, eg Cochrane library. Consequently, non-filtered databases, eg PubMed, Google Scholar and Egyptian Knowledge Bank searched and full-text high-quality research articles were carefully analysed to draw recommendations. Other relevant publications with low quality of evidence like case studies and short communications were also reviewed to address practice advices. Although Ramadan fasting was found beneficial for patients with NAFLD, it was found deleterious to patients with Child B and C cirrhosis and patients with peptic ulcer. Patients with chronic hepatitis, Child A cirrhosis and those with non-complicated liver transplant can fast with prefasting assessment and strict follow up.
