Atrophic gastritis is a process of chronic inflammation of the gastric mucosa of the stomach, leading to a loss of gastric glandular cells and their eventual replacement by intestinal and fibrous tissues. As a result, the stomach's secretion of essential substances such as hydrochloric acid, pepsin, and intrinsic factor is impaired, leading to ...
A lack of hydrochloric acid produced by the stomach is one of the most common age-related causes of a harmed digestive system. [6] Among men and women, 27% experience a varying degree of achlorhydria. US researchers found that over 30% of women and men over the age of 60 have little to no acid secretion in the stomach.
Stomach biopsy, to test for gastritis and other conditions [27] The OLGA staging frame of chronic gastritis on histopathology. Atrophy is scored as the percentage of atrophic glands and scored on a four-tiered scale. No atrophy (0%) = score 0; mild atrophy (1–30%) = score 1; moderate atrophy (31–60%) = score 2; severe atrophy (>60%) = score 3.
6% (< 60 years old), 20% (> 60 years old) [4] Vitamin B12 deficiency, also known as cobalamin deficiency, is the medical condition in which the blood and tissue have a lower than normal level of vitamin B 12. [5] Symptoms can vary from none to severe. [1] Mild deficiency may have few or absent symptoms. [1]
Reactive hypoglycemia, postprandial hypoglycemia, or sugar crash is a term describing recurrent episodes of symptomatic hypoglycemia occurring within four hours [1] after a high carbohydrate meal in people with and without diabetes. [2] The term is not necessarily a diagnosis since it requires an evaluation to determine the cause of the ...
Hiccups can also be a symptom of a medical condition. Pullins says that neurological conditions such as multiple sclerosis or Parkinson's disease, for instance, can cause one to experience hiccups ...
Gastric acid or stomach acid is the acidic component – hydrochloric acid of gastric juice, produced by parietal cells in the gastric glands of the stomach lining. With a pH of between one and three, gastric acid plays a key role in the digestion of proteins by activating digestive enzymes, which together break down the long chains of amino ...
Peptic ulcer disease is a break in the inner lining of the stomach, the first part of the small intestine, or sometimes the lower esophagus. [1][7] An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. [1] The most common symptoms of a duodenal ulcer are waking at night with upper ...
