  • Diabetes mellitus type 1/type 2 (glucosuria) [renal magnesium loss].
  • Hyperaldosteronism [renal magnesium loss]
  • Hypercalcemia [renal magnesium loss due to inhibition of tubular magnesium reabsorption]
  • Hyperthyroidism (e.g., Graves’ disease) [renal magnesium loss]
  • Hypoparathyroidism (parathyroid hypofunction) [renal magnesium depletion]
  • Malnutrition
  • Metabolic acidosis (metabolic acidosis) [renal magnesium loss].

Infectious and parasitic diseases (A00-B99).

Liver, gallbladder, and biliary tract-pancreas (pancreas) (K70-K77; K80-K87).

  • Crohn’s disease – chronic inflammatory bowel disease; it usually runs in relapses and can affect the entire digestive tract; characteristic is the segmental affection of the intestinal mucosa (intestinal mucosa), that is, it may be affected several intestinal segments that are separated by healthy sections from each other
  • Non-infectious gastroenteritis, unspecified.
  • Celiac disease (synonyms: celiac disease; coeliac disease; indigenous sprue; gluten allergy; gluten-induced enteropathy; gluten-sensitive enteropathy; gluten intolerance) – chronic disease of the small intestinal mucosa due to hypersensitivity to the cereal protein gluten* .

Psyche – nervous system (F00-F99; G00-G99).

  • Alcohol abuse
  • Anorexia nervosa (anorexia)
  • Delir
  • Laxative abuse (misuse of laxatives).
