[dropcap]L[/dropcap]ow stomach acid production is a common disorder in celiac disease and dermatitis herpetiformis that is characterized by lack of sufficient hydrochloric acid needed 1) to properly digest food, which results in malnutrition and subsequent nutritional deficiencies, and 2) to destroy swallowed bacteria and other microbes, which may allow infections to develop.
It is also common in the general population, as well, affecting 50% of people age 60 years and about 80% by age 85 years. Nevertheless, low stomach acid is not generally looked for as a cause of acute and chronic disorders that rob health with far-reaching effects.
[box type=”shadow” ]Understanding Stomach Acid Production and Function
The stomach digests incoming food into a liquid state, thereby releasing nutrients so they can be absorbed by the small intestine. Powerful stomach muscles churn food and mix it with gastric juice, dissolving and breaking it down.
Gastric juice is produced by gastric glands located in the stomach lining. These numerous, microscopic glands produce about 3 liters of juice a day. Gastric juice is composed of a high concentration of

[dropcap]L[/dropcap]ymphocytic gastritis is an inflammatory stomach disorder that is characterized by superficial inflammation of the stomach lining (mucosa) that mainly involves the gastric antrum in children.
Lymphocytic gastritis is defined by the recognition of more than 25 intraepithelial lymphocytes (IEL) per 100 surface epithelial cells lining the stomach wall.
Q: What are intraepithelial lymphocytes?
A: Intraepithelial lymphocytes in lymphocytic gastritis are a unique T-cell population of white blood cells that are interspersed between epithelial cells in the mucosa.

What Is Osteoporosis?
[dropcap]O[/dropcap]steoporosis is a metabolic bone disorder characterized by diminished bone mass (density) with normal cell appearance but fragile bone strength that prediposes to broken bones, and with high bone turnover.
This condition usually goes undetected until late when loss of height or a bone fracture occurs. In fact, each year 1.5 million fractures mainly of the hip, spine and wrist are attributed to osteoporosis. Compression fractures of vertebrae bones are the most common, accounting for 700,000 cases.
Bone is composed of specialized connective tissue called osseous tissue. Osseous tissue is made up of living bone cells (osteocytes) that are embedded in a hard matrix (framework) of calcified substance.
Bone matrix contains collagen fibers and the minerals calcium phosphate and calcium carbonate, which provide strength to bone. The copper enzyme, lysyl oxidase, is involved in the cross-linking of collagen in forming the framework for depositing calcium and other minerals to build and repair bone.
Q: How do osteocytes function in bone?
A: Osteocytes maintain the health of bone by their metabolic activity in regulating normal bone turnover. Bone turnover is the breaking down and removal of old or damaged bone and rebuilding or remodeling of healthy bone that is ongoing throughout life. The bone formation process takes about 3 months to complete.
Osteoporosis develops from failure of the body to maintain health and to provide bone tissue with adequate nutrition for proper function. Risk factors that can be modified include: low calcium intake, sedentary lifestyle, smoking, drinking alcohol excessively, eating a diet with excessive caffeine, protein, and phosphate, and taking certain medications over a long time such as steroids, thyroid preparations, the anti-convulsive drug phenytoin, aspirin, antacids, anticoagulants, some diuretics, and some chemotherapeutic drugs. See below for a fuller description.
In addition to celiac disease, osteoporosis is associated with advancing age, family history, nulliparity (no pregnancies) and post-menopause in females, certain disorders such as hyperthyroidism, hypogonadism, inflammatory bowel disease like Crohn’s disease, multiple myeloma, anorexia nervosa, and Cushing’s disease.
Bone strength is easily measured by testing bone mineral density (BMD). BMD is evaluated by DEXA scan (dual-energy X-ray absorptiometry). DEXA at the femoral neck and lumbar spine is considered the gold standard to confirm the diagnosis of osteoporosis. Results are expressed as T and Z scores. T scores compare the result with a 20 to 40 year old helathy person while Z scores compare the result with persons in the same age group. Both are measured in standard deviations (SD).
According to WHO criteria (World Health Organization), a T-score of -1 SD or greater denotes normal bone, a T-score between −1 to −2.5 SD denotes osteopenia, and a T-score of −2.5 or more denotes osteoporosis.1
Treatment is aimed to preserve and increase bone density, minimize symptoms for better quality of life and reduce risk of bone fractures.
What Is Osteoporosis In Celiac Disease and/or Gluten Sensitivity?
The cumulative effects of gluten-induced inflammation, treatment delay, and malabsorption result in lower bone density and bone fragility.2

[dropcap]M[/dropcap]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
