How do you make an excuse letter for being absent in school because you have lbm and stomach ache?

To write an excuse letter for being absent from school due to LBM (loose bowel movement) and a stomach ache, start with your address and date at the top. Then, address the letter to your teacher or school principal, and clearly state your name, grade, and the dates of your absence. Briefly explain that you were unwell due to digestive issues and express your intention to catch up on any missed work. Finally, thank them for their understanding and support.
