Electrolyte imbalance. Diagram of ion concentrations and charge across a semi-permeable cellular membrane. Electrolyte imbalance, or water-electrolyte imbalance, is an abnormality in the concentration of electrolytes in the body. Electrolytes play a vital role in maintaining homeostasis in the body. They help to regulate heart and neurological ...
Lactic acidosis is a medical condition characterized by a build-up of lactate (especially L -lactate) in the body, with formation of an excessively low pH in the bloodstream. It is a form of metabolic acidosis, in which excessive acid accumulates due to a problem with the body's oxidative metabolism. Lactic acidosis is typically the result of ...
Gastroenterology. Cyclic vomiting syndrome (CVS) is a chronic functional condition of unknown pathogenesis. CVS is characterized as recurring episodes lasting a single day to multiple weeks. Each episode is divided into four phases: inter-episodic, prodrome, vomiting, and recovery. Inter-episodic phase (symptom free phase), is characterized as ...
Nausea. A 1681 painting depicting a person vomiting. Specialty. Gastroenterology. 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.
Metabolic alkalosis is an acid-base disorder in which the pH of tissue is elevated beyond the normal range (7.35–7.45). This is the result of decreased hydrogen ion concentration, leading to increased bicarbonate (HCO− 3), or alternatively a direct result of increased bicarbonate concentrations. The condition typically cannot last long if ...
The pancreas is a large organ behind the stomach that produces digestive enzymes and a number of hormones. [1] There are two main types: acute pancreatitis, and chronic pancreatitis. [1] Signs and symptoms of pancreatitis include pain in the upper abdomen, nausea and vomiting. [1] The pain often goes into the back and is usually severe. [1]
Metabolic acidosis can lead to acidemia, which is defined as arterial blood pH that is lower than 7.35. [6] Acidemia and acidosis are not mutually exclusive – pH and hydrogen ion concentrations also depend on the coexistence of other acid-base disorders; therefore, pH levels in people with metabolic acidosis can range from low to high.
Some patients may experience severe nausea and vomiting, which can lead to dehydration, as evidenced by orthostatic hypotension as well as acute renal insufficiency. Some patients with severe gastroparesis lose a significant amount of weight and suffer from nutritional deficiencies, necessitating small bowel feeding access to bypass the stomach ...
