What Is Chronic Constipation?

Chronic constipation is an intestinal motility disorder characterized by abnormal stool formation, consistency, and evacuation.

Motility disorder means the normal rhythmic movement of intestinal muscles, called peristalsis, that moves food matter through the gut is hampered or dysfunctional.

Studies show that methane gas present in the colon induces constipation by delaying transit time, which is the time it takes for stool to pass through the colon.

Researchers investigating the relationship between methane and constipation found that methane positivity was detected in 75% of patients with slow transit, 44% of patients with normal transit and and 28% of the patients who were controls. However, methane positivity was not related with stool consistency.1

Other researchers investigating the total amount of methane produced found that there was significantly more methane production in patients with constipation (21.1 ppm vs. 6.1 ppm, respectively) than in controls without constipation.2

Q. How does methane get into the colon?

A. 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 substrate (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. Methane is detected in 30%-50% of the healthy adult population worldwide.3

Other common causes of constipation include not getting enough exercise, not drinking enough fluids, not eating enough fiber in the diet, not eating foods that supply microbes needed by the colon (probiotics), not eating foods that nourish the good microbe population (prebiotics) and supply minerals needed for healthy movement of stool, and food sensitivities. Too much cows milk is a common cause of stool that forms into balls.

Who is Affected in the General Population? Chronic constipation is a remarkably common and costly condition that can negatively impact the quality of life and result in a major social and economic burden. Based on the definition, either self-reported or using Rome criteria, chronic constipation can affect up to 27% of the population. There is strong evidence that constipation occurs more frequently in women.4

Dementia

DementiaWhat Is Dementia?

Dementia is the term used to describe a group of symptoms that show significant deterioration of an individual’s intellectual and social abilities.

The deterioration in intellectual function is progressive and is characterized by memory and cognitive impairment involving deficits in reasoning, judgment, abstract thought, comprehension, learning, use of language, and task execution.

Some types of dementia can be reversed,  while most types of dementia are degenerative or nonreversible.

Q: What causes dementia?

A: There are  many differing causes of dementia.  Here are some causes according to nonreversible and reversible:

  • Nonreversible dementia may not be turned back due to these conditions:
  • Alzheimer’s disease is the most common type of degenerative dementia caused by abnormal protein structures in certain areas of the brain. 
  • Lewy body disease is a leading cause of dementia in elderly adults.
  • Vascular dementia due to many small strokes.
  • Medical conditions: Huntington’s disease, multiple sclerosis, infections that can affect the brain, such as HIV/AIDS and Lyme disease, Parkinson’s disease, Pick’s disease, and progressive supranuclear palsy.
  • Reversible dementia may be stopped or reversed if these conditions are found soon enough:
  • Brain injury.
  • Brain tumors.
  • Chronic alcohol abuse.
  • Changes in blood sugar, sodium, and calcium levels.
  • Changes that can occur with celiac disease, diabetes, thyroid disease, and other metabolic disorders.
  • Nutritional deficiencies.
  • Use of certain medications, including cimetadine and some cholesterol-lowering medications.1

What Is A Gastric Ulcer?

G astric ulcer is a painful stomach disorder characterized by an open sore involving the mucosa lining and deeper muscle layer of the stomach.

Gastric ulcer is associated with lymphocytic gastritis which is inflammation of the mucosal lining of the stomach. The thick mucosal lining normally protects the stomach from the erosive action of stomach acid.

Q: How do ulcers develop?

A: Ulcers develop if  hydrochloric acid secreted by the gastric glands of the stomach for the purpose of digesting food damages the normally resistant mucosal walls of the stomach. In the reverse, ulcers may be accompanied by achlorhydria (insufficient acid production).

Damage occurs when there is a predisposing factor that alters the health of the mucosal lining. The most common cause is infection with a bacteria called h. pylori bacter, stress and chronic use of the pain relievers aspirin and non-steroidal drugs like ibuprofen.

Smoking tocacco and consuming alcohol aggravate an ulcer but do not cause it to develop.

The most common location for ulcer formation is along the stomach antrum which is the area of the stomach before the pylorus, the lower region that empties liquid stomach contents into the small intestine.

What Are Erosions In The Second Part Of The Duodenum?

E rosions in the second part of the duodenum typically are superficial excoriations (sores) in the mucosal lining that do not penetrate into the muscle layer as does an ulcer.

Of note, most erosions develop in the first part of the duodenum rather than the second part.

Q: Are duodenal erosions serious?

A: Yes duodenal erosions are serious and can be life-threatening for the following reasons:

  • Duodenal erosions may occur together with gastric erosions, therefore they can jointly induce massive bleeding.
  • Duodenal erosions may be associated with duodenal ulcer but hemorrhage originates from the erosion and the ulcer itself does not bleed.
  • Duodenal erosion in itself might induce bleeding. The intensity of bleeding, if there is no hemorrhage from other places, is not so severe, as the one originating from gastric erosions.1

What Is Postbulbar Duodenal Ulceration/Stenosis?

P ostbulbar duodenal ulceration is a chronic inflammatory disorder characterized by thickening of the intestinal lining with excoriation penetrating the muscularis mucosae (muscle layer of the intestine) associated with villous atrophy.

The ulcer is well-defined. Stenosis due to thickening of the area narrows the hollow inside of the duodenum which impairs passage of foodstuffs and may lead to obstruction.

Q: Is postbulbar duodenal ulceration painful?

A: Postbulbar duodenal ulceration may not cause symptoms but usually causes gnawing pain that is relieved by eating food. After eating there develops nausea and bloating.

Complications include obstruction, bleeding, and perforation of the duodenal lining. Ulcers do not usually become malignant.

What Are Multiple Gastric Ulcerations?

M ultiple gastric ulcerations denote a stomach disorder that involves damage to the superficial mucosa characterized by many sores of the stomach antrum that are marked by inflammation, necrosis (death of the affected cells) and sloughing of destroyed tissue.

Q: Where is the stomach antrum?

A: The antrum is the lower region of the stomach before the pylorus which is nearest the duodenum (first part of the small intestine). The stomach and duodenum are separated by the powerful pyloric sphincter.

The stomach antrum propels food in the stomach against the pylorus which resists passage of food until it is turned into chyme. Chyme is highly acidic liquified food that has been thoroughly mixed with stomach juices.

Gastric ulcerations are typically associated with widespread gastritis (inflammation), inflammatory involvement of acid producing cells, and atrophy of acid and pepsin producing cells.1

The primary causes of gastric ulcerations are H. pylori infection, use of Aspirin and non-steroidal drugs (NSAIDS), and stress.1

What Is Collagenous Gastritis?

C ollagenous gastritis is a rarely reported stomach disorder characterized by the deposition of a subepithelial collagen band and accompanying inflammatory infiltrate in the stomach wall.

A subepithelial collagen band means that collagen, a tough fibrous protein, has abnormally accumulated under the surface layer of epithelial cells which form the mucosa lining the stomach.

The surface mucosa may remain intact and not show lymphocytosis and/or gastritis on endoscopic examination or it may become stripped off and bleed from entrapped capillaries. Biopsy is necessary to diagnose collagenous gastritis.1

Q: Why does collagen become deposited under the surface lining of the stomach?

A: It is thought that collagen deposition is preceded by inflammation and tissue damage. However, the natural history and pathogenesis of collagenous gastritis remain unclear.2

What Is Lymphocytic Colitis?

L ymphocytic colitis is a microscopic inflammation of the large intestinal mucosa with infiltration of lymphocytes (IELs)  that is characterized by non-bloody secretory diarrhea.

Secretory diarrhea describes bowel movements that consist of a large volume of liquid stool.

Q: What are IELs?

A: IELs is an abbreviation for intraepithelial lymphocytes, which are white blood cells that infiltrate within epithelial cells or between them. Epithelial cells form the surface mucosa of the large intestine also called the colon.

The histopathological criteria (biopsy) for lymphocytic colitis are a density of at least 20 IELs per 100 surface epithelial cells; chronic inflammatory infiltrate of mononuclear cells in the lamina propria; epithelial damage; and a subepithelial collagen layer of less than 10 µm. The increased collagen band consists basically of collagen type I and III, which are the subtypes produced by repair functions, indicating a reactive origin.1That is, the mucosa is reacting to some irritative substance.

Up to 10% of adults undergoing colonoscopy for investigation of chronic diarrhea and having visibily normal appearing mucosa may have lymphocytic colitis.2

Bile acid malabsorption has been shown to coexist in 60% of patients with lymphocytic colitis.1

Lymphocytic colitis (LC) is categorized as primary or secondary.  Primary LC is a clinical and histopathological disease of unknown cause. Secondary LC may develop as the result of iritating factors acting on the colon such as smoking or many medications.  In one study, the most common drug treatments as a percentage of the study group were corticosteroids (32.1%), proton pump inhibitors (26.0%), antidepressant drugs, specifically selective serotonin reuptake inhibitors (21.4%), angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists (18.3%), statins (17.6%), thyroid hormones (17.6%), and beta-blockers (16.0%).3

Secondary lymphocytic colitis is associated with several concomitant diseases including celiac disease. This is why lymphocytic changes must be interpreted with caution before considering them as a separate entity of autoimmune origin, instead of secondary reactions to ischemia and toxic stimulants. Efforts must be made to better classify and diagnose patients with real, primary lymphocytic colitis to avoid over-prescription of corticosteroids for treatment.3

Apathy

Cows Milk enteropathyWhat Is Milk Intolerance (Bovine Beta Casein Enteropathy)?

B ovine beta casein enteropathy is characterized by raised serum IgA antibodies to bovine beta casein found by blood testing and damage to mucosa of the jejunum found by biopsy.

The jejunum is the second section of the small intestine, between the duodenum and the ileum.

Mucosa damage is similar to damage caused by gluten.

Q: What is bovine beta casein?

A: Bovine beta casein is a protein found in cow’s milk.

An immune reaction to protein in milk is totally different from lactose intolerance. Lactose intolerance develops from deficiency of an intestinal enzyme called lactase which is required to digest lactose, the sugar in milk.
