These deficiencies also may result from malabsorption syndromes
, rather than from a dietary deficiency.
The treatment of tuberculosis in the presence of malabsorption syndromes
Independent of UVB exposure, the following medical conditions can cause vitamin D deficiency: fat malabsorption syndromes
(Crohn's disease, cystic fibrosis, gastric bypass), kidney failure, significantly impaired liver function, and seizure disorders (not directly from the seizures but from long-term use of medications to treat seizures, such as phenobarbitol and phenytoin).
12] deficiency is unlikely to occur except under special circumstances, such as the presence of pernicious anemia, vegetarianism, malabsorption syndromes
, bacterial overgrowth, and other clinical conditions in which the function of the ileum is impaired (2, 3).
This chapter would have been improved with a brief mention of other malabsorption syndromes
such as intestinal lymphangiectasia, transporter defects such as oasthouse syndrome and enzyme deficiencies such a trehalase and sucrase isomaltase deficiency The section on anorexia nervosa seems to be predominantly a psychological overview.
However, Vitamin D deficiency can also be due to confinement in the home for medical or other reasons, diet, malabsorption syndromes
and liver or kidney disease.
Patients at increased risk for vitamin D insufficiency (for example, those who are nursing-home bound, chronically ill or over age 70) and who have gastrointestinal malabsorption syndromes
should receive vitamin D supplementation in addition to that provided in Fosamax Plus D.
those who are nursing-home bound, chronically ill, over the age of 70 years) and with gastrointestinal malabsorption syndromes
should receive vitamin D supplementation in addition to that provided in FOSAMAX PLUS D.
Gastrointestinal manifestations include a myriad of conditions, mostly malabsorption syndromes
and infectious diarrhea.

Inflammatory diarrhea Inflammatory bowel disease Infectious diseases Ischemic colitis Radiation colitis Neoplasia Secretory diarrhea Irritable bowel syndrome Laxative abuse Fecal incontinence Congenital syndromes (chloridorrhea) Idiopathic secretory diarrhea Bacterial toxins Drugs and poisons Disordered motility Neuroendocrine tumors Neoplasia Addison's disease Epidemic secretory (Brainerd) diarrhea
for treatment of malabsorption syndromes
, intestinal disorders, coronary
Because bacterial metabolism alters folic acid status and intestinal bacterial colonization is altered by nutritional factors and carbohydrate malabsorption syndromes
, dietary measurements should not rely solely on folic acid supplementation but should also consider carbohydrate malabsorption syndromes
, especially fructose malabsorption.
gt; Selection of therapeutic agent should be individualized based on patient-specific factors including fracture history, severity of osteoporosis (T-scores), risk for hip fracture, patterns of BMD, comorbid conditions (such as peptic ulcer disease, gastroesophageal reflux, malabsorption syndromes
, malignancy), cost, and other factors.
