Enteritis
Enteritis is inflammation of the small intestine. It is most commonly caused by food or drink contaminated with pathogenic microbes,Dugdale, David C., IIII, and George F Longretc"Enteritis" MedlinePlus Medical Encyclopedia, 18 October 2008. Accessed 24 August 2009. such as ''Serratia'', but may have other causes such as NSAIDs, radiation therapy as well as autoimmune conditions like coeliac disease. Symptoms may include abdominal pain, cramping, diarrhoea, dehydration, and fever. Related diseases of the gastrointestinal (GI) system (including gastritis, gastroenteritis, colitis, and enterocolitis) may involve inflammation of the stomach and large intestine. Duodenitis, jejunitis, and ileitis are subtypes of enteritis which are localised to a specific part of the small intestine. Inflammation of both the stomach and small intestine is referred to as gastroenteritis. Signs and symptoms Signs and symptoms of enteritis are highly variable and vary based on the specific cause ...

Ileitis
Ileitis is an inflammation of the ileum, a portion of the small intestine. ''Mycobacterium tuberculosis'' infection may mimic Crohn's disease Ileitis. Ileitis may be linked to a broad range of illnesses, such as sarcoidosis, amyloidosis, ischemia, neoplasms, spondyloarthropathies, vasculitides, drug-related conditions, and eosinophilic enteritis.` Signs and symptoms When it comes to ileitis, the majority of cases are caused by an acute, self-limited form of lower right quadrant pain and/or diarrhea. However, other conditions, such as ''M. tuberculosis'' or vasculitis, can cause chronic, debilitating symptoms that are complicated by hemorrhage, obstructive symptoms, and/or extraintestinal manifestations. Unless symptoms indicate that additional testing is necessary, ileitis linked to spondyloarthropathy or nonsteroidal anti-inflammatory drugs A nonsteroidal compound is a drug that is not a steroid nor a steroid derivative. Nonsteroidal anti-inflammatory drugs (NSAIDs) are di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ileum
The ileum () is the final section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms posterior intestine or distal intestine may be used instead of ileum. Its main function is to absorb vitamin B12, vitamin B12, bile salts, and whatever products of digestion that were not absorbed by the jejunum. The ileum follows the duodenum and jejunum and is separated from the cecum by the ileocecal valve (ICV). In humans, the ileum is about 2–4 m long, and the pH is usually between 7 and 8 (neutral or slightly base (chemistry), basic). ''Ileum'' is derived from the Greek word εἰλεός (eileós), referring to a medical condition known as ileus. Structure The ileum is the third and final part of the small intestine. It follows the jejunum and ends at the ileocecal junction, where the wikt:terminal, terminal ileum communicates with the cecum of the large intestine thro ...

Gastroenteritis
Gastroenteritis, also known as infectious diarrhea, is an inflammation of the Human gastrointestinal tract, gastrointestinal tract including the stomach and intestine. Symptoms may include diarrhea, vomiting, and abdominal pain. Fever, lack of energy, and dehydration may also occur. This typically lasts less than two weeks. Although it is not related to influenza, in the U.S it is sometimes called the "stomach flu". Gastroenteritis is usually caused by viruses; however, gut bacteria, parasites, and fungus, fungi can also cause gastroenteritis. In children, rotavirus is the most common cause of severe disease. In adults, norovirus and ''Campylobacter'' are common causes. Eating improperly prepared food, drinking contaminated water or close contact with a person who is infected can #Transmission, spread the disease. Treatment is generally the same with or without a definitive diagnosis, so testing to confirm is usually not needed. For young children in impoverished countries, pre ...

Coeliac Disease
Coeliac disease (British English) or celiac disease (American English) is a long-term autoimmune disorder, primarily affecting the small intestine. Patients develop intolerance to gluten, which is present in foods such as wheat, rye, spelt and barley. Classic symptoms include gastrointestinal problems such as chronic diarrhoea, abdominal distention, malabsorption, loss of appetite, and among children failure to grow normally. Non-classic symptoms are more common, especially in people older than two years. There may be mild or absent gastrointestinal symptoms, a wide number of symptoms involving any part of the body, or no obvious symptoms. Due to the frequency of these symptoms, coeliac disease is often considered a systemic disease, rather than a gastrointestinal condition. Coeliac disease was first described as a disease which initially presents during childhood; however, it may develop at any age. It is associated with other autoimmune diseases, such as Type 1 d ...

Large Intestine
The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the Digestion, digestive system in tetrapods. Water is absorbed here and the remaining waste material is stored in the rectum as feces before being removed by defecation. The Colon (anatomy), colon (progressing from the ascending colon to the transverse colon, transverse, the descending colon, descending and finally the sigmoid colon) is the longest portion of the large intestine, and the terms "large intestine" and "colon" are often used interchangeably, but most sources define the large intestine as the combination of the cecum, colon, rectum, and anal canal. Some other sources exclude the anal canal. In humans, the large intestine begins in the right iliac region of the pelvis, just at or below the waist, where it is joined to the end of the small intestine at the cecum, via the ileocecal valve. It then continues as the colon ascending colon, ascending the abdomen, across t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crohn's Disease
Crohn's disease is a type of inflammatory bowel disease (IBD) that may affect any segment of the gastrointestinal tract. Symptoms often include abdominal pain, diarrhea, fever, abdominal distension, and weight loss. Complications outside of the gastrointestinal tract may include anemia, skin rashes, arthritis, uveitis, inflammation of the eye, and fatigue (medical), fatigue. The skin rashes may be due to infections, as well as pyoderma gangrenosum or erythema nodosum. Bowel obstruction may occur as a complication of chronic inflammation, and those with the disease are at greater risk of colon cancer and small bowel cancer. Although the precise causes of Crohn's disease (CD) are unknown, it is believed to be caused by a combination of environmental, Immunity (medical), immune, and bacterial factors in genetically susceptible individuals. It results in a Immune-mediated inflammatory diseases, chronic inflammatory disorder, in which the body's immune system defends the gastrointesti ...

Weight Loss
Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, by a mean loss of fluid, body fat (adipose tissue), or lean mass (namely bone mineral deposits, muscle, tendon, and other connective tissue). Weight loss can either occur unintentionally because of malnourishment or an underlying disease, or from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or increase in exercise is called cachexia and may be a symptom of a serious medical condition. Intentional Intentional weight loss is the loss of total body mass as a result of efforts to improve physical fitness, fitness and health, or to change Human physical appearance, appearance through slimming.

Vomiting
Vomiting (also known as emesis, puking and throwing up) is the forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose. Vomiting can be the result of ailments like food poisoning, gastroenteritis, pregnancy, motion sickness, or hangover; or it can be an after effect of diseases such as brain tumors, elevated intracranial pressure, or overexposure to ionizing radiation. The feeling that one is about to vomit is called nausea; it often precedes, but does not always lead to vomiting. Impairment due to alcohol or anesthesia can cause inhalation of vomit. In severe cases, where dehydration develops, intravenous fluid may be required. Antiemetics are sometimes necessary to suppress nausea and vomiting. Self-induced vomiting can be a component of an eating disorder such as bulimia nervosa, and is itself now classified as an eating disorder on its own, purging disorder. Complications Aspiration Vomiting is dangerous if gastric content e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nausea
Nausea is a diffuse sensation of unease and discomfort, sometimes perceived as an urge to vomit. It can be a debilitating symptom if prolonged and has been described as placing discomfort on the chest, abdomen, or back of the throat. Over 30 definitions of nausea were proposed in a 2011 book on the topic. Nausea is a non-specific symptom, which means that it has many possible causes. Some common causes of nausea are gastroenteritis and other gastrointestinal disorders, food poisoning, motion sickness, dizziness, migraine, fainting, low blood sugar, anxiety, hyperthermia, dehydration and lack of sleep. Nausea is a side effect of many medications including chemotherapy, or morning sickness in early pregnancy. Nausea may also be caused by disgust and depression. Medications taken to prevent and treat nausea and vomiting are called antiemetics. The most commonly prescribed antiemetics in the US are promethazine, metoclopramide, and the newer ondansetron. The word na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diarrhea
Diarrhea (American English), also spelled diarrhoea or diarrhœa (British English), is the condition of having at least three loose, liquid, or watery bowel movements in a day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed, however, are normal. What is diarrhea? How is it caused, treated and prevented? (see also script)The most common cause is an infection of the intestines due to a virus, bacterium, or parasite—a condition also known as gastroenteritis. These infections are often acquired from food or water that has been contaminated by feces, or directly from another person who is infected. The three types of diarrhea ...

Cramp
A cramp is a sudden, involuntary, painful skeletal muscle contraction or overshortening associated with electrical activity. While generally temporary and non-damaging, they can cause significant pain and a paralysis-like immobility of the affected muscle. A cramp usually goes away on its own over several seconds or (sometimes) minutes. Cramps are common and tend to occur at rest, usually at night (nocturnal leg cramps). They are also often associated with pregnancy, physical exercise or overexertion, and age (common in older adults); in such cases, cramps are called idiopathic because there is no underlying pathology. In addition to those benign conditions cramps are also associated with many pathological conditions. Cramp definition is narrower than the definition of muscle spasm: spasms include any involuntary abnormal muscle contractions, while cramps are sustained and painful. True cramps can be distinguished from other cramp-like conditions. Cramps are different from mus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abdominal Pain
Abdominal pain, also known as a stomach ache, is a symptom associated with both non-serious and serious medical issues. Since the abdomen contains most of the body's vital organs, it can be an indicator of a wide variety of diseases. Given that, approaching the examination of a person and planning of a differential diagnosis is extremely important. Common causes of pain in the abdomen include gastroenteritis and irritable bowel syndrome. About 15% of people have a more serious underlying condition such as appendicitis, leaking or ruptured abdominal aortic aneurysm, diverticulitis, or ectopic pregnancy. In a third of cases, the exact cause is unclear. Signs and symptoms The onset of abdominal pain can be abrupt, quick, or gradual. Sudden onset pain happens in a split second. Rapidly onset pain starts mild and gets worse over the next few minutes. Pain that gradually intensifies only after several hours or even days has passed is referred to as gradual onset pain. One can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
