This study was conducted to assess the changes in hemoglobin (Hb) levels among students over a period of three months. A total of 70 students participated in the study. Hb levels were measured every month and categorized as increased, decreased, or not changed. In the first month, the majority of students showed a decrease in Hb level. During the second month, a gradual improvement was observed in some students. By the third month, a significant number of students showed an increase in Hb level. Overall analysis showed that 46.6% of students had increased Hb levels, 48.6% showed decreased levels, and 4.8% had no change. The results indicate fluctuations in Hb levels over time. Proper nutrition and awareness may help improve Hb levels. This study highlights the importance of regular monitoring of hemoglobin among students.
