Background: Hemorrhoids, also called as piles are masses or clumps of tissues which consist of muscle and elastic fibres with enlarged, bulging blood vessels and surrounding supporting tissues present in the anal canal of an individual. It is a condition characterized by the prolapsed of an anal cushion that may result in bleeding and pain.1 Objectives: 1. To assess the knowledge regarding prevention of hemorrhoids. 2. To assess the effectiveness of planned teaching on knowledge regarding prevention of hemorrhoids. 3. To associate the findings with demographic variables. Material and Methods: Total 60 people, male and female were included in this study. Data regarding demographic and knowledge regarding prevention of hemorrhoids was collected based on planned teaching on knowledge regarding prevention of hemorrhoids. Results: There was a significant difference between pre-test and post test knowledge scores interpreting planned teaching on knowledge regarding prevention of hemorrhoids. Mean value of pre-test is 3.87 and post test is 15.55 and a standard deviation value of pre-test is 1.420 and post test is 2.715. The paired t test value is 0.214 and p value is 0.101. Hence it is statistically interpreted that the planned teaching on knowledge regarding prevention of hemorrhoids is effective. Hence, the findings of this study reveal that the research hypothesis (H1) is accepted and the null hypothesis (H0) is rejected. Conclusion: The actual cause of hemorrhoids remains unknown. But it is proposed to be caused by temperament, body habits, customs, passions, sedentary life, tight-laced clothes and climate. Patients with spinal cord injuries constipation, chronic diarrhoea, poor bathroom habits, postponing bowel movements, and a poor-fibre diet are also considered to be contributing causes. Imparting knowledge regarding hemorrhoids help them to live quality of life and to take preventive measures to avoid its complications.
