Background: Fasting during the month of Ramadan provides researchers w
ith a good opportunity to study experimental hunger. Methods: The case
histories of patients brought to Ankara Numune Hospital and hospitali
zed there because of peptic ulcer complaints during the period 1987-92
were retrospectively studied. Results: The ratio of peptic ulcer comp
lications was in all the years of the study higher during Ramadan than
during the periods before Ramadan (0.05 > p > 0.01) and after Ramadan
(0.1 > p > 0.05). Female patients tended to develop more haemorrhage
and perforations during Ramadan. In the peptic ulcer perforation group
the average age of women was significantly higher during Ramadan, whe
reas it was significantly lower in men. Conclusions: A type of partial
hunger during Ramadan increased peptic ulcer complications.
