What this Trial Is About
Researchers are investigating magnesium deficiency in people with gastrointestinal diseases such as Crohn's disease, ulcerative colitis, ileostomy, or bile acid diarrhoea. These conditions increase the risk of magnesium loss, which is important for functions like muscle movement, nerve signals, heart rhythm, and bone strength. The study aims to find how common magnesium deficiency is in these groups and to identify the best ways to measure magnesium levels in clinical care since standard blood tests may not accurately reflect true magnesium status.
