Background: During pregnancy, the rapidly rising hormones such as estrogen, progesterone, and prolactin change the maternal body into a suitable environment for the fetus and may cause some symptoms in the mother called as minor disorders. Minor disorders are effectively managed at home. Therefore, it is important that a mother should possess an adequate knowledge of the common minor disorders and their management. Objective: To find the effectiveness of a structured teaching program on the minor disorders for pregnancy and their home management. Materials and Methods: A quasi-experimental study with a quantitative approach was undertaken to obtain an error-free result. A total of 100 antenatal mothers were consecutively recruited from a selected setting. Result: Before the implementation of a planned teaching program, the antenatal mothers showed a poor knowledge of the common minor disorders (19.56 ± 12.73), whereas after the implementation, the knowledge significantly improved with the difference of 18.02 ± 0.742 revealing the effectiveness of the planned teaching program. Conclusion: Teaching about minor disorders of pregnancy and its home management helps the mothers to manage their minor disorders at home itself and continue their pregnancy more comfortably and securely.
