Objectives Bangladesh is a densely populated country in south-east Asia with paucity of research in suicide. This systematic review was aimed at critical appraising various aspects of suicide in Bangladesh based on available literature and systematic search. Methods Extensive literature search was conducted in Scopus, PubMed, PubMed Central, Google, Google Scholar and BanglaJOL with searching key words without any date boundary and without any basis of types of studies, that is, all types of studies were scrutinised. The author focused on sources of suicide data along with epidemiological variables of suicides in Bangladesh such as suicide rate, gender of victims, methods of suicides, risk factors and prevention activities and role of media in suicide. Results After exclusion of repetitions, screening was performed, and finally, 35 articles were selected for review. Amongst the 35 articles, 16 articles were original contributions, 2 systematic reviews, 6 narrative reviews, 2 scoping reviews, 3 editorials, 3 case reports and rest correspondence article. The review revealed that the actual rate of suicide in Bangladesh is yet to come out and quality data is a real challenge. Women are dying more than the men, and early adulthood is the most vulnerable time of life. Discussion Suicide is a under attended problem in Bangladesh, as the country yet to reveal the actual rate of suicide along with the challenge of quality data. Prevention activities have been started but yet to be visualised. Decriminalisation of suicide in the legal criteria and establishment of suicide surveillance can be the top priorities in the country.
