Which of the following is a self-help measure for primary dysmenorrhea?

Regular exercise is an effective self-help measure for managing primary dysmenorrhea, which is characterized by painful menstrual cramps not associated with any underlying reproductive pathology. Engaging in regular physical activity helps improve blood circulation and can release endorphins, which are the body’s natural pain relievers. Exercise has also been shown to reduce the severity and duration of menstrual cramps for many individuals.

The other options are treatment modalities that do not fall under self-help measures. Antibiotic therapy is primarily used to treat infections and not indicated for dysmenorrhea unless there is a concomitant infection. Daily hormone injections are typically reserved for specific hormonal imbalances or conditions and are not self-administered. Intravenous fluids are used in situations of dehydration or severe medical conditions, not for primary dysmenorrhea. Regular exercise stands out as a practical, accessible, and empowering approach to alleviating menstrual discomfort.
