Anorexia (loss of appetite), weight loss, and vomiting can be presenting symptoms of many diseases. (tripod.com)
Public awareness of eating disorders is high, and since few public awareness campaigns have mentioned medical illness being a cause of anorexia or vomiting, a young person experienceing nausea or anorexia may be quite secretive about it, fearing they have a psychiatric disorder. (tripod.com)
Listed below are several chronic conditions that may cause anorexia, weight loss, or vomiting. (tripod.com)
Why some patients develop anorexia while others vomit after meals is an area future research should focus on (see page on research suggestions ). (tripod.com)
Ansaid - eye drops, which are used to treat myosis during operations and prevention of the development of reactive postoperative inflammation of the eyes. (trusledtablets.com)
Psychiatric1
The CNS mediates vomiting that arises from psychiatric disorders and stress from higher brain centers. (wikipedia.org)
Esophagus4
Repeated or profuse vomiting may cause erosions to the esophagus or small tears in the esophageal mucosa (Mallory-Weiss tear). (wikipedia.org)
Intrathoracic pressure lowers (by inspiration against a closed glottis), coupled with an increase in abdominal pressure as the abdominal muscles contract, propels stomach contents into the esophagus as the lower esophageal sphincter relaxes. (wikipedia.org)
The stomach itself does not contract in the process of vomiting except for at the angular notch, nor is there any retroperistalsis in the esophagus. (wikipedia.org)
It is also used to promote healing of erosive esophagitis (damage to your esophagus caused by stomach acid). (fr.nf)
Excessive3
Prolonged and excessive vomiting depletes the body of water (dehydration), and may alter the electrolyte status. (wikipedia.org)
Generic Aciphex is used to treat symptoms of gastroesophageal reflux disease (GERD) and other conditions involving excessive stomach acid such as Zollinger-Ellison syndrome. (fr.nf)
Recurrent vomiting, such as observed in bulimia nervosa, may lead to the destruction of the tooth enamel due to the acidity of the vomit. (wikipedia.org)
Receptors on the floor of the fourth ventricle of the brain represent a chemoreceptor trigger zone, known as the area postrema, stimulation of which can lead to vomiting. (wikipedia.org)
A number of conditions involving balance such as motion sickness and vertigo can lead to nausea and vomiting. (explained.today)
Research1
Research on nausea and vomiting has relied on using animal models to mimic the anatomy and neuropharmacologic features of the human body. (explained.today)
it can therefore be stimulated by blood-borne drugs that can stimulate vomiting or inhibit it. (wikipedia.org)
Blood1
This may become apparent if fresh red blood is mixed with vomit after several episodes. (wikipedia.org)
Small1
Retroperistalsis starts from the middle of the small intestine and sweeps up digestive tract contents into the stomach, through the relaxed pyloric sphincter. (wikipedia.org)
Purging disorder1
Self-induced vomiting can be a component of an eating disorder such as bulimia, and is itself now classified as an eating disorder on its own, purging disorder. (wikipedia.org)
Chemoreceptor trig3
Receptors on the floor of the fourth ventricle of the brain represent a chemoreceptor trigger zone, known as the area postrema, stimulation of which can lead to vomiting. (wikipedia.org)
There are various sources of input to the vomiting center: The chemoreceptor trigger zone at the base of the fourth ventricle has numerous dopamine D2 receptors, serotonin 5-HT3 receptors, opioid receptors, acetylcholine receptors, and receptors for substance P. Stimulation of different receptors are involved in different pathways leading to emesis, in the final common pathway substance P appears involved. (wikipedia.org)
The vomiting act encompasses three types of outputs initiated by the chemoreceptor trigger zone: Motor, parasympathetic nervous system (PNS), and sympathetic nervous system (SNS). (wikipedia.org)
The patient often presents with chronic upper abdominal symptoms such as abdominal pain, nausea, eructation, voluminous vomiting (bilious or partially digested food), postprandial discomfort, early satiety, and sometimes, subacute small bowel obstruction. (medscape.com)
Anorexia1
Nausea is a vague, intensely disagreeable sensation of sickness or "queasiness" and is distinguished from anorexia. (mhmedical.com)
Respiratory2
Vomiting is dangerous if gastric content enters the respiratory tract. (wikipedia.org)
Vomiting often follows, as does retching (spasmodic respiratory and abdominal movements). (mhmedical.com)
Stress1
The CNS mediates vomiting that arises from psychiatric disorders and stress from higher brain centers. (wikipedia.org)
Food1
Increased liquid retention in the fundus and prolonged solid food retention in both the proximal and distal stomach occur in diabetic patients with gastroparesis, demonstrating altered intragastric distribution. (medscape.com)
Results1
A less frequent occurrence results from a vomiting of intestinal contents, including bile acids and HCO− 3. (wikipedia.org)
Patients1
For example, patients receiving chemotherapy may start vomiting in anticipation of its administration. (mhmedical.com)
