Coffee-ground-like vomit suggests less severe bleeding in the stomach because the gastric acid has had time to change the composition of the blood; Yellow or green vomit suggests bile, indicating that the pyloric valve is open and bile is flowing into the stomach from the duodenum. This may occur during successive episodes of vomiting after the ...
Nausea is a diffuse sensation of unease and discomfort, sometimes perceived as an urge to vomit. [1] It can be a debilitating symptom if prolonged and has been described as placing discomfort on the chest, abdomen, or back of the throat.
For example, there are many sensory conflicts that are associated with motion sickness and many that are not, but those in which canal stimulation occurs in the absence of normal otolith function (e.g., in free fall) are the most provocative. The vestibular imbalance theory is also tied to the different roles of the otoliths and canals in ...
Vomiting is a common condition affecting about 50% of pregnant women, with another 25% having nausea. [53] However, the incidence of HG is only 0.3–1.5%. [ 4 ] After preterm labor, hyperemesis gravidarum is the second most common reason for hospital admission during the first half of pregnancy. [ 16 ]
Diagnosis of contraction alkalosis is made by correlating laboratory data with clinical history and examination. Metabolic alkalosis in the presence of decreased effective circulatory volume, loop diuretic use, or other causes of intravascular depletion such as profound diarrhea should raise suspicion for contraction alkalosis as a likely etiology in the absence of other causes.
Nausea and vomiting can be extremely distressing for patients, and so is one of their major concerns. [10] Vomiting has been associated with major complications, such as pulmonary aspiration of gastric content, and might endanger surgical outcomes after certain procedures, for example after maxillofacial surgery with wired jaws.
Recovery phase is typically the phase where vomiting ceases, nausea diminishes or is absent, and appetite returns. "Cyclic vomiting syndrome (CVS) is a rare abnormality of the neuroendocrine system that affects 2% of children." [1] This disorder is thought to be closely related to migraines and family history of migraines. [2] [3]
The differential diagnosis can be complicated somewhat if the person exhibits only vomiting or diarrhea (rather than both). [1] Appendicitis may present with vomiting, abdominal pain, and a small amount of diarrhea in up to 33% of cases. [1] This is in contrast to the large amount of diarrhea that is typical of gastroenteritis. [1]
