Which abbreviation refers to an indicator of digestive health?

The abbreviation that indicates digestive health is BM, which stands for "bowel movement." Tracking bowel movements is a crucial aspect of assessing digestive health, as it provides insights into a person's gastrointestinal function. Regularity, consistency, and any accompanying symptoms related to bowel movements can help healthcare providers identify potential digestive issues or disorders.

While other abbreviations may pertain to different medical contexts—such as BKA for below-knee amputation, BOM which could refer to various things in medical terminology (often used to describe a medication order), and BLS for basic life support—they do not specifically relate to indicators of digestive health. This makes BM the clear choice in the context of monitoring and understanding digestive conditions.
