There was no difference in menstrual cycle abnormalities during Ramadan fasting between the respondents who started fasting in follicular phase or luteal phase (p > 0.05). However, for menstrual blood quantification, there was a significant difference between menstrual blood volume before and during Ramadan fasting marked by the increased mean in menstrual blood volume as much as 13.84 mL with p value < 0.001. Conclusion: During Ramadan fasting, there were changes in teenagers’ menstrual cycle especially in menstrual blood volume.
