Vitamin D is the principle regulator of calcium homeostasis (balance) in the body. This “vitamin” is really a prohormone, meaning it acts like a hormone but is not. Vitamin D does, however, contain cholesterol in its molecular structure like steroid hormones.
The physiological importance of vitamin D encompasses much more than the regulation of bone metabolism although this is a mighty function.
Q: How does vitamin D regulate bone metabolism?
A: In regulation of bone metabolism, vitamin D works in three ways: 1) enables active absorption of calcium from the small intestine, 2) enhances reabsortion of calcium by the kidneys that would otherwise be excreted in urine, and 3) plays an active role in skeletal development and bone mineralization. Mineralization gives strength to living bone tissue.
Vitamin D interacts with receptors within cells to effect transcriptional changes in many cell types including those in gut, bone, breast, prostate, brain, skeletal muscle, and the immune system.1
In regards to the essential role of vitamin D in muscle tissue, it has been recently shown that vitamin D regulates both muscle function and structure of primary myofibers.2
Vitamin D is converted in the body to a molecule that is biologically active. The active form is 1,25-dihydroxyvitamin D, usually referred to as vitamin D3. About 80% comes from sun exposure and the remaining from food.
Vitamin D3 is synthesized in the skin from 7-dehydrocholesterol via photochemical reactions requiring UV light (sunlight). That is, light that contains energy from the sun is incorporated into molecules of 7-dehydrocholesterol in the underlying dermis of skin to make this vitamin. This is why inadequate exposure to sunlight contributes to vitamin D deficiency.
Blood concentration of 25(OH)D is the best indicator of vitamin D status. It reflects vitamin D produced in the skin and that obtained from food and supplements and has a fairly long circulating half-life of 15 days.3

Hypomagnesemia means the level of magnesium in the bloodstream is too low to meet metabolic needs of the body for this mineral.
Q: What are the metabolic needs of the body for magnesium?
A: The metabolic needs of the body for magnesium are numerous which gives rise to very many distressing symptoms when this mineral is deficient.
A major function of magnesium is to stabilize the structure of an enzyme called adenosine triphosphate (ATP) within cells for the production of energy. In the brain, magnesium plays important roles in all the major metabolisms such as oxidation-reduction and regulation of ions (charged minerals).1

U rticaria is an immune based skin disorder characterized by multiple eruptions of well-demarcated edematous, intensely pruritic (itchy) plaques that may be small or reach the diameter of many centimeters with surrounding erythema (redness) each lasting less than 24 hours.1
Q: What is the immune reaction in hives?
A: Hives form when, in response to histamine, blood plasma leaks out of small blood vessels in the skin. Histamine is a chemical released from specialized cells along the skin’s blood vessels. Allergic reactions, chemicals in certain foods, insect stings, sunlight exposure, or medications can all cause histamine release.2
In many patients, in spite of extensive investigations, the cause remains elusive. The term idiopathic is often used to denote this category. Now it is known that autoimmunity is the cause of chronic urticaria in 50% of cases.
Treatment is generally started with nonsedating antihistamine in the daytime and sedating antihistamine in the night.3

Zincemia means the zinc level in blood plasma is too low to meet metabolic needs of the body for this mineral.
Q: How important is a normal blood level of zinc?
A: A low blood level of zinc is characterized by widespread alterations in energy metabolism, growth, hemoglobin, carbon dioxide transport, hormone activity, insulin storage, many enzyme activities, prostaglandin function, collagen production, male fertility, protein synthesis, and vitamin A metabolism.

Obnoxious gas, or flatus, is gas that is not only offensive when passed but also lingers in the air longer than ordinary gas does.
Gas is a natural digestive product within the colon that is composed mainly of hydrogen and carbon dioxide gases. These gases are given off in the necessary bacterial breakdown of undigested fermentable food entering the colon from the small intestine.
Q: What makes gas obnoxious?
A: The production of obnoxious gas depends on the type and quantity of undigested food residue that is passed into the colon from the small intestine, dysfunctional motility instead of normal peristalsis, and dysbiosis. Dysbiosis is the condition of having unhealthy or insufficient populations of microbes responsible for digesting (fermenting) foodstuffs in the lower gut or colon.
Gases produced by intestinal microbes may modulate intestinal motor function (muscle movement) in individuals with functional bowel disease. Methane, produced by enteric bacteria in the human gut, is associated with slowed intestinal transit and constipation.1

Methane is produced in the colon by intestinal methanogens (microbes) that metabolize hydrogen, one of the end products of normal anaerobic (meaning without oxygen) bacterial fermentation. Fermentation of the undigested starchy part of carbohydrates produces hydrogen in the intestine, which is the food for methane production by intestinal methanogens.
Hydrogen and methane are excreted in the flatus and in breath giving the opportunity to indirectly measure their production using breath testing. ((Triantafyllou K, Chang C, Pimentel M.

Gluten sensitive enteropathy is active celiac disease characterized by inflammation of the small intestinal mucosa that results from an inherited immunologic intolerance to ingested gluten.
Q: What does the inflammation do to the mucosa in the small intestine?
A: Inflammation is a cell level immune response to gluten that has these effects on the mucosa:
Damages the barely visible villi (multitudinous finger-like structures) by causing atrophy or loss.
Likely affects the structural support and microcirculation of the villus, leading to collapse of the villus.
Elongates the crypts between villi. The thickening of the crypt is not so much a response to loss of surface enterocytes but represents inflammation of the mucosa.1
Increases round cells in the lamina propria and surface epithelial cells leaving few, irregular microvilli (brush border) on the surface of villi.
Damage is most intense in the duodenum and decreases toward the large intestine.
The extent of the damage to the intestine determines the malabsorptive consequences of the disease. Both gastric and small intestinal permeability are disrupted in patients with celiac disease.2
Relationship between active celiac disease and intestinal permeability: There is a clear association between degree of mucosal damage and the intestinal-permeability ratio, and a normal ratio generally implies near-normal small intestinal structure. A raised intestinal permeability of the mucosal lining (leaky gut) could predispose to a high absorption of gluten and exacerbate an existing lesion and hence convert a latent to an overt enteropathy.3
Relationship between active celiac disease and tight junction proteins: A study of intestinal permeability showed that the expression of all junction proteins of the small intestinal lining (occludin, claudin 3, zonula occludens 1, and E-cadherin) was already decreased in early stage celiac disease when compared with non-celiac controls, showing leaky gut and confirming the above earlier study by Johnston et al. Junction protein expression correlated positively with mucosal villus structure and negatively with the number of intraepithelial lymphocytes (IELs), the intensity of small-intestinal autoantibody deposits, and serum autoantibodies. The expression of claudin 3 showed a negative correlation with diarrheal score.4
Relationship between active celiac disease and inflammation. In celiac disease there is an over production of inflammatory interleukin-15 (IL-15) which inhibits the correct removal of damaged intraepithelial lymphocytes caused by the reaction to gluten. Serum levels of IL-15 are directly correlated with the seriousness of tissue damage.5
Relationship between active celiac disease and gut microbiota. Results of a study investigating intestinal microbiota (normal bacterial residents) in patients with celiac disease suggest that with lower levels of the genus bifidobacteria, celiac patients have an imbalance in the intestinal microbiota even while on a gluten-free diet. This fact could favor the pathological process of the disorder. The concentration of bifidobacteria per gram of feces was significantly higher in healthy subjects (2.5 ± 1.5 x107 CFU/g) when compared to celiac patients (1.5 ± 0.63 x108 CFU/g).6
Relationship between active celiac disease and endoscopy technique. The most severe degree of villous atrophy was detected when distal duodenal biopsy specimens were taken in addition to a duodenal bulb biopsy specimen from either the 9- or 12-o’clock position (96.4% sensitivity; 95% CI, 79.7%-100%). The difference between the 12-o’clock position biopsy and the 3-o’clock position biopsy in detecting the most severe villous atrophy was 92% (24/26 patients) versus 65% (17/26 patients).7
Relationship between active celiac disease and diet adherence. Patients with consistent gluten free diet adherence experience symptomatic responses to dietary gluten (SRDG) faster and more severe in comparison to their prior gluten exposure possibly demonstrating an adept immunological response. Anxiety and depression also enhance the speed of symptom onset and co-existing visceral hypersensitivity is a risk factor for severe reactions to dietary gluten.8
Relationship between active celiac disease and atrial fibrillation: Patients with celiac disease, verified by intestinal biopsy, are at increased risk of atrial fibrillation. This observation is consistent with previous findings that elevation of inflammatory markers predicts atrial fibrillation.9
