Gastrointestinal metabolism

  1. Gastrointestinal bleeding
    Gastrointestinal bleeding is a problem that doctors in the USA often encounter (300 thousand hospitalizations annually). The degree of hemorrhage varies from small slow bleeding to life-threatening conditions that contribute to the development of iron deficiency anemia. Mortality from upper gastrointestinal tract in the USA is 8%. This indicator has not changed much.
  2. Gastrointestinal Lymphoma
    In systemic dissemination of non-Hodgkin lymphoma (see chapter 13), any segment of the gastrointestinal tract may be involved again. However, up to 40% of lymphomas develop not in the lymph nodes, but in other organs, among which the intestine is the most frequent localization. By the time of recognition of the primary lymphoma of the gastrointestinal tract, the tumor process does not affect either the liver or
  3. Gastrointestinal Tumors
    In the organs of the gastrointestinal tract (hollow organs, pancreas, liver, biliary tree), various types of tumors are much more common than in other systems of the body, and such patients have a much higher degree of probability of death. However, there is no single simple explanation for the etiology of tumors of the gastrointestinal tract. International studies
  4. Gastrointestinal tract, kidneys and liver.
    Changes in the gastrointestinal tract during pregnancy are associated mainly with the anatomical displacement of the enlarged uterus. The axis of the stomach changes its position from vertical to horizontal, which leads to an increase in intragastric pressure and a change in the angle of connection of the stomach with the esophagus. This in turn leads to relative insufficiency of the esophageal sphincter. If
  5. Gastrointestinal tract
    More than half of pregnant women have an increase in appetite, weight gain can reach 400 g per week, and by the end of pregnancy is 12 kg. Such a change in the regulation of feelings of hunger and satiety provides increased needs of the mother's body for energy and plastic materials. Often there are taste perversions and whims associated with a change in the secretory function of the gastrointestinal tract.
  6. Gastrointestinal diseases
    ANATOMICAL FEATURES OF THE GASTROINTESTINAL TRACT Features of the gastrointestinal tract determine the specifics of the clinical picture in pathological conditions. The oral cavity in the newborn is poorly developed, the mucous membrane is well vascularized, but relatively dry due to a small amount of saliva. The saliva of the newborn does not play a significant role in digestion, since it practically does not contain enzymes and
  7. Gastrointestinal diseases
    Conditions leading to dysphagia Causes: • tumor esophageal stricture; • ???? achalasia; • ???? diffuse spasm of the esophagus; • ???? medicinal esophagitis; • ???? hiatal hernia; • ???? collagenoses; • ???? chemical burn of the esophagus; • ???? diverticulum of the esophagus; • ???? esophageal infections (candidiasis). Features of anesthesia: • preoperative preparation is needed
  8. LOSING OF GASTRACTIVE TREATMENT JUICES
    Loss of juice in surgery plays a large role (vomiting, intestinal obstruction, fistulas of the gastrointestinal canal, diarrhea, exudation, etc.). In this case, a wide variety of violations occur (Table 18). If a pathological loss of juice occurred before admission to the hospital and targeted treatment, then the violations are eliminated in accordance with the principles set out in the chapter “The therapeutic plan
  9. Acute and chronic bleeding from the gastrointestinal tract
    There are many causes of gastrointestinal bleeding. Bleeding develops according to one of two primary mechanisms: 1. Violation of the integrity of the mucous membrane, leading to exposure of deep vessels, their erosion. For example, bleeding from a stomach ulcer, bleeding from the intestines during infectious or idiopathic processes, from the small and large intestines during ischemia. 2.
  10. STUDY OF GASTROINTESTINAL TRACT BODIES
    SURVEY ALGORITHM {foto29} Fig. 16. Algorithm for examination of the gastrointestinal tract. Examination of the gastrointestinal tract consists of examination, palpation, percussion and auscultation (Fig. 16). From the anamnesis we learn about the nature of food intake, diet, dependence of pain on the time of eating, etc. The main manifestations are bitterness in the mouth, bad breath. Swallowing (free,
  11. Digestion disorders in the gastrointestinal tract
    Protein digestion disorders can occur at the stage of gastric, intestinal, parietal digestion. In the stomach, peptide hydrolases cleave peptide bonds between aromatic and dicarboxylic amino acids. Protein digestion sharply slows down in hypoacid conditions, especially in case of achilia and total gastric resection (if the pH does not reach at least 5.0 units). Without
  12. Gastrointestinal nutrition and cancer
    Cancer of the transverse colon and rectum Many theories have been put forward about the role of nutrition in the development of colon cancer. The human diet includes a large number of substances with mutagenic and carcinogenic properties, as well as antagonists and blockers of these compounds. Therefore, it is very difficult to determine which of them has a damaging effect. Carcinogens that damage the upper sections
  13. Gastrointestinal Disorder Syndrome
    The leading symptom is loose stools (diarrhea). Etiology. The cause of the gastrointestinal tract upset syndrome in children is most often acute intestinal infections (AEI), AEI is a large group of diseases, the main clinical manifestations of which are loose stools, dyspeptic disorders, symptoms of intoxication and dehydration. Most acute respiratory infections in children have
  14. Bleeding from the upper gastrointestinal tract
    It is customary to talk about bleeding from the upper gastrointestinal tract (GIT) in cases where the source of bleeding is located either in the esophagus, or in the stomach, or in the duodenum (duodenum). Pathophysiology The most common causes of bleeding in adults are: duodenal ulcer; erosion of the stomach and duodenum; varicose veins
  15. NOSOCOMIAL INFECTIONS OF THE GASTROINTESTINAL TRACT
    According to a survey of nosocomial infections in the United States, gastroenteritis develops in approximately 10.5 people per 10 thousand received in medical institutions. The etiology of gastrointestinal infections can be established in approximately 97% of cases; of which bacteria account for 93%. The predominant bacterial pathogen is C. difficile - 91%, viruses (rotaviruses) account for 5.3%. Allocate
  16. Practical recommendations for the normalization of the gastrointestinal tract
    Now, having gotten a little acquainted with the technology of the gastrointestinal tract, one should act in accordance with it. So, practical recommendations. Do not drink plenty of fluids before meals. Enzymes are diluted and washed off into the underlying sections of the gastrointestinal tract. Do not drink plenty of fluids immediately after eating. Drinking liquid will not only dilute the digestive juices of the small intestine, but also wash it off
  17. GASTROINTESTINAL INFECTIONS
    CLASSIFICATION Gastrointestinal infections are classified according to their primary location, etiology, and clinical presentation. Among the diseases of bacterial etiology, there are infections of the orocervical region (not considered in this chapter), infections of the stomach (gastritis, peptic ulcer and duodenal ulcer), intestinal infections - acute diarrhea (enteritis and
