Heartburn
Heartburn is a burning sensation felt behind the breastbone. It is a symptom that is commonly linked to acid reflux and is often triggered by food, particularly fatty, sugary, spicy, chocolate, citrus, onion-based and tomato-based products. Lying down, bending, lifting, and performing certain exercises can exacerbate heartburn. Causes include acid reflux, gastroesophageal reflux disease (GERD), damage to the esophageal lining, bile acid, mechanical stimulation to the esophagus, and esophageal hypersensitivity. Heartburn affects 25% of the population at least once a month. Endoscopy and esophageal pH monitoring can be used to evaluate heartburn. Some causes of heartburn, such as GERD, may be diagnosed based on symptoms alone. Potential Differential diagnosis, differential diagnoses for heartburn include motility disorders, ulcers, Esophagitis, inflammation of the esophagus, and medication side effects. Lifestyle changes, such as weight loss, losing weight and avoiding fatty food ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acid Reflux
Gastroesophageal reflux disease (GERD) or gastro-oesophageal reflux disease (GORD) is a chronic upper gastrointestinal disease in which stomach content persistently and regularly flows up into the esophagus, resulting in symptoms and/or complications. Symptoms include dental corrosion, dysphagia, heartburn, odynophagia, regurgitation, non-cardiac chest pain, extraesophageal symptoms such as chronic cough, hoarseness, reflux-induced laryngitis, or asthma. In the long term, and when not treated, complications such as esophagitis, esophageal stricture, and Barrett's esophagus may arise. Risk factors include obesity, pregnancy, smoking, hiatal hernia, and taking certain medications. Medications that may cause or worsen the disease include benzodiazepines, calcium channel blockers, tricyclic antidepressants, NSAIDs, and certain asthma medicines. Acid reflux is due to poor closure of the lower esophageal sphincter, which is at the junction between the stomach and the esopha ...

Gastroparesis
Gastroparesis (gastro- from Ancient Greek – gaster, "stomach"; and -paresis, πάρεσις – "partial paralysis") is a medical disorder of ineffective neuromuscular contractions (peristalsis) of the stomach, resulting in food and liquid remaining in the stomach for a prolonged period. Stomach contents thus exit more slowly into the duodenum of the digestive tract, a medical sign called delayed gastric emptying. The opposite of this, where stomach contents exit quickly into the duodenum, is called dumping syndrome. Symptoms include nausea, vomiting, abdominal pain, feeling full soon after beginning to eat (early satiety), abdominal bloating, and heartburn. Many or most cases are Idiopathic disease, idiopathic. The most commonly known cause is autonomic neuropathy of the vagus nerve, which innervates the stomach. Uncontrolled diabetes mellitus is a frequent cause of this nerve damage, but trauma to the vagus nerve is also possible. Some cases may be considered post-in ...

Antacid
An antacid is a substance which neutralization (chemistry), neutralizes gastric acid, stomach acidity and is used to relieve heartburn, indigestion, or an upset stomach. Some antacids have been used in the treatment of constipation and diarrhea. Marketed antacids contain Salt (chemistry), salts of aluminum, calcium, magnesium, or sodium. Some preparations contain a combination of two Salt (chemistry), salts, such as magnesium carbonate and aluminum hydroxide (e.g., hydrotalcite). Medical uses Antacids are available over the counter and are taken by mouth to quickly relieve occasional heartburn, the major symptom of gastroesophageal reflux disease and indigestion. Treatment with antacids alone is Symptomatic treatment, symptomatic and only justified for minor symptoms. Alternative uses for antacids include constipation, diarrhea, hyperphosphatemia, and urinary alkalization. Some antacids are also used as an Adjuvant therapy, adjunct to pancreatic enzyme replacement therapy in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peptic Ulcer
Peptic ulcer disease is when the inner part of the stomach's gastric mucosa (lining of the stomach), the first part of the small intestine, or sometimes the lower esophagus, gets damaged. An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. The most common symptoms of a duodenal ulcer are waking at night with epigastrium, upper abdominal pain, and upper abdominal pain that improves with eating. With a gastric ulcer, the pain may worsen with eating. The pain is often described as a dyspepsia, burning or dull ache. Other symptoms include belching, vomiting, weight loss, or Anorexia (symptom), poor appetite. About a third of older people with peptic ulcers have no symptoms. Complications may include gastrointestinal bleeding, bleeding, gastrointestinal perforation, perforation, and gastric outlet obstruction, blockage of the stomach. Bleeding occurs in as many as 15% of cases. Common causes include infection with ''Hel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Esophagitis
Esophagitis, also spelled oesophagitis, is a disease characterized by inflammation of the esophagus. The esophagus is a tube composed of a mucosal lining, and longitudinal and circular smooth muscle fibers. It connects the pharynx to the stomach; swallowed food and liquids normally pass through it. Esophagitis can be asymptomatic; or can cause epigastric and/or substernal burning pain, especially when lying down or straining; and can make swallowing difficult ( dysphagia). The most common cause of esophagitis is the reverse flow of acid from the stomach into the lower esophagus: gastroesophageal reflux disease (GERD). __TOC__ Signs and symptoms The symptoms of esophagitis include: * Heartburn – a burning sensation in the lower mid-chest * Nausea * Dysphagia – swallowing is painful, with difficulty passing or inability to pass food through the esophagus * Vomiting (emesis) * Abdominal pain * Cough Complications If the disease remains untreated, it can cause scar ...

Proton-pump Inhibitor
Proton-pump inhibitors (PPIs) are a class of medications that cause a profound and prolonged reduction of gastric acid, stomach acid production. They do so by irreversibly inhibiting the stomach's H+/K+ ATPase, H+/K+ ATPase proton pump. The body eventually synthesizes new proton pumps to replace the irreversibly inhibited ones, a process driven by normal cellular turnover, which gradually restores acid production. Proton-pump inhibitors have largely superseded the H2-receptor antagonist, H2-receptor antagonists, a group of medications with similar effects but a different mode of action, and heavy use of antacids. A potassium-competitive acid blocker (PCAB) revaprazan was marketed in Korea as an alternative to a PPI. A newer PCAB vonoprazan with a faster and longer lasting action than revaprazan, and PPIs has been marketed in Japan (2013), Russia (2021), and the US (2023). PPIs are among the most widely sold medications in the world. The class of proton-pump inhibitor medication ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Esophageal PH Monitoring
In gastroenterology, esophageal pH monitoring is the current gold standard for diagnosis of gastroesophageal reflux disease (GERD). It provides direct physiologic measurement of acid in the esophagus and is the most objective method to document reflux disease, assess the severity of the disease and monitor the response of the disease to medical or surgical treatment. It can also be used in diagnosing laryngopharyngeal reflux. Background The importance of refluxed gastric contents in the pathogenesis of GERD was emphasized by Winkelstein who introduced the term " peptic esophagitis" and by Bernstein and Baker who reported the symptom of heartburn following instillation of hydrochloric acid in the distal esophagus in what then became known as the acid perfusion test. Formal measurement of acid in the esophagus was first described in 1960 by Tuttle. He used a glass pH probe to map the gastroesophageal pH gradient, and demonstrated a sharp gradient in normal subjects and a ...

Differential Diagnosis
In healthcare, a differential diagnosis (DDx) is a method of analysis that distinguishes a particular disease or condition from others that present with similar clinical features. Differential diagnostic procedures are used by clinicians to diagnose the specific disease in a patient, or, at least, to consider any imminently life-threatening conditions. Often, each possible disease is called a differential diagnosis (e.g., acute bronchitis could be a differential diagnosis in the evaluation of a cough, even if the final diagnosis is common cold). More generally, a differential diagnostic procedure is a systematic diagnostic method used to identify the presence of a disease entity where multiple alternatives are possible. This method may employ algorithms, akin to the process of elimination, or at least a process of obtaining information that decreases the "probabilities" of candidate conditions to negligible levels, by using evidence such as symptoms, patient history, and medi ...

Achalasia
Esophageal achalasia, often referred to simply as achalasia, is a failure of smooth muscle fibers to relax, which can cause the lower esophageal sphincter to remain closed. Without a modifier, "achalasia" usually refers to achalasia of the esophagus. Achalasia can happen at various points along the human gastrointestinal tract, gastrointestinal tract; achalasia of the rectum, for instance, may occur in Hirschsprung's disease. The lower esophageal sphincter is a muscle between the esophagus and stomach that opens when food comes in. It closes to avoid Gastric acid, stomach acids from coming back up. A fully understood cause to the disease is unknown, as are factors that increase the risk of its appearance. Suggestions of a Genetic disorder, genetically transmittable form of achalasia exist, but this is neither fully understood, nor agreed upon. Esophageal achalasia is an esophageal motility disorder involving the smooth muscle cell, smooth muscle layer of the esophagus and the lowe ...

Sleep Deprivation
Sleep deprivation, also known as sleep insufficiency or sleeplessness, is the condition of not having adequate duration and/or quality of sleep to support decent alertness, performance, and health. It can be either Chronic (medicine), chronic or Acute (medicine), acute and may vary widely in severity. All known animals sleep or exhibit some form of sleep behavior, and the importance of sleep is self-evident for humans, as nearly a third of a person's life is spent sleeping. Sleep deprivation is common as it affects about one-third of the population. The National Sleep Foundation recommends that adults aim for 7–9 hours of sleep per night, while children and teenagers require even more. For healthy individuals with normal sleep, the appropriate sleep duration for school-aged children is between 9 and 11 hours. Acute sleep deprivation occurs when a person sleeps less than usual or does not sleep at all for a short period, typically lasting one to two days. However, if the slee ...
