Poor disease management of cystic fibrosis can result in the following:
- Destruction of pancreatic tissue.
- Reduced enzymatic activity that causes nutrient malabsorption.
- Blockage of ducts leading to and from the pancreas.
Weight gain during infancy and childhood is typically not a result of poor disease management; in fact, children with cystic fibrosis often struggle with maintaining a healthy weight due to malabsorption issues and increased energy demands. Therefore, that option is not applicable in this context.
