Download or read book Colonic Motility written by Sushil K. Sarna and published by Biota Publishing. This book was released on 2010-11-01 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three distinct types of contractions perform colonic motility functions. Rhythmic phasic contractions (RPCs) cause slow net distal propulsion with extensive mixing/turning over. Infrequently occurring giant migrating contractions (GMCs) produce mass movements. Tonic contractions aid RPCs in their motor function. The spatiotemporal patterns of these contractions differ markedly. The amplitude and distance of propagation of a GMC are several-fold larger than those of an RPC. The enteric neurons and smooth muscle cells are the core regulators of all three types of contractions. The regulation of contractions by these mechanisms is modifiable by extrinsic factors: CNS, autonomic neurons, hormones, inflammatory mediators, and stress mediators. Only the GMCs produce descending inhibition, which accommodates the large bolus being propelled without increasing muscle tone. The strong compression of the colon wall generates afferent signals that are below nociceptive threshold in healthy subjects. However, these signals become nociceptive; if the amplitudes of GMCs increase, afferent nerves become hypersensitive, or descending inhibition is impaired. The GMCs also provide the force for rapid propulsion of feces and descending inhibition to relax the internal anal sphincter during defecation. The dysregulation of GMCs is a major factor in colonic motility disorders: irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and diverticular disease (DD). Frequent mass movements by GMCs cause diarrhea in diarrhea predominant IBS, IBD, and DD, while a decrease in the frequency of GMCs causes constipation. The GMCs generate the afferent signals for intermittent short-lived episodes of abdominal cramping in these disorders. Epigenetic dysregulation due to adverse events in early life is one of the major factors in generating the symptoms of IBS in adulthood.

Download or read book Neuro Immuno Gastroenterology written by Cris S. Constantinescu and published by Springer. This book was released on 2016-05-24 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses important issues regarding the interaction between the nervous system, the immune system, and the digestive system. Gut flora has a profound influence on the shaping of the immune response, not only in the gastrointestinal system but also in the nervous system. Fascinatingly, manipulation of intestinal immune responses can be used to modulate neurological disease. Conversely, the nervous system and the psyche have significant effects on the functioning of the gut and liver. After introductory chapters on the neurology, the immunology and microbiology of the gut, the effects of the gut immune system and gut flora and its manipulation on neurological disease are discussed, followed by molecular mimicry and immune tolerance in neuroimmune diseases. Additionally, several chapters deal with gastrointestinal manifestations of neurological diseases. Neuro-Immuno-Gastroenterology is aimed at neurologists, gastroenterologists, and immunologists.

Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews the most recent knowledge in the field of gastrointestinal motility in health and disease. The topics addressed include basic as well as clinical data concerning the motor functions of the entire gut: the lower oesophageal sphincter and the gastro-oesophageal reflux; the gastric emptying and the role of the pylorus; the motility of the biliary tract and its disorders; the cyclic motor activity of the gut and intestinal transit; the colonic and ano-rectal motility. There are also impOltant contributions in physiology and pharmacology relating to the neurohumoral regulation of the gut, and the function of digestive smooth muscle. Several papers explore the nature of the linkage between brain and gut. a link which has long been deduced by clinicians but not, until recently, systematically explored by scientists. The individual papers, selected from a large number of submissions, have been subject to 'peer-review' by an inter national committee which includes both cliniCians and basic scientists. Therefore this book should serve as an up to date source of information for researchers concerned with basic sciences as well as for clinicians in gastroenterology, medicine and surgery. C.

Download or read book Functional Somatic Symptoms in Children and Adolescents written by Kasia Kozlowska and published by Springer Nature. This book was released on 2020-09-30 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book sets out the stress-system model for functional somatic symptoms in children and adolescents. The book begins by exploring the initial encounter between the paediatrician, child, and family, moves through the assessment process, including the formulation and the treatment contract, and then describes the various forms of treatment that are designed to settle the child’s dysregulated stress system. This approach both provides a new understanding of how such symptoms emerge – typically, through a history of recurrent or chronic stress, either physical or psychological – and points the way to effective assessment, management, and treatment that put the child (and family) back on the road to health and well-being.

Download or read book Eating Mindfully written by Susan Albers and published by ReadHowYouWant.com. This book was released on 2009-12-14 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: How common and effortless it is to eat in an uncontrolled, unaware, mindless manner. If you've ever continued to snack when you were full, cut calories despite being hungry, or used guilt to guide your eating, you've experienced mindless eating firsthand. Let's face it. Deciding what to eat is not an easy task. It's so tricky that in the United States eating concerns and weight obsessions have reached epidemic proportions, with serious health consequences for a large part of the population. What turns an everyday activity like eating into such an overwhelming process? The answer to that question is, of course, a complex one. Throughout the book, we will return to that question with some answers. But the bottom line is this: To make smart, healthy eating choices, your body and mind work together to send you essential clues about what you need and want to eat. These clues give you information about ''how much'' and ''what'' to eat. The sensations and emotions that signal when you're full, famished, or just wanting to eat something rich and delicious are a complex combination of bodily and emotional feelings. If you are attentive and responsive to these cues, your eating will be healthy, in control, and well regulated. Dieting and disliking your body are incredibly detrimental to your emotional, mental, and physical well-being. They inhibit your ability to accurately decode your body's messages and feedback. The dieting mindset is akin to taking a knife and cutting the connection that is your body's only line of communication with your head. The dieting mindset can skew your knowledge of healthy eating so badly that you have no idea of what to eat. Mindless eating is then manifested in two ways. You can either ''obsess'' or ''ignore'' internal feedback from both your body and mind, rather than responding thoughtfully to your hunger and to your concern about your health. In this book, you will learn how mindlessness unknowingly corrupts the way you eat a meal, and how it manifests in a variety of eating problems. You will gain insight into why mindfulness, which is, of course, the opposite of mindlessness, can provide you with valuable skills to control the way you eat.
