Sucrose intolerance or genetic sucrase-isomaltase deficiency (GSID) is the condition in which sucrase-isomaltase, an enzyme needed for proper metabolism of sucrose (sugar) and starch (e.g., grains), is not produced or the enzyme produced is either partially functional or non-functional in the small intestine.
Causes Gastrectomy , gastric bypass surgery , diabetes , esophageal surgery , absent or inefficient pyloric sphincter , pyloric stenosis Dumping syndrome occurs when food, especially sugar, moves too quickly from the stomach to the duodenum —the first part of the small intestine—in the upper gastrointestinal (GI) tract .
Control of the digestive system is also maintained by ENS, which can be thought of as a digestive brain that can help to regulate motility, secretion and growth. Sensory information from the digestive system can be received, integrated and acted upon by the enteric system alone. When this occurs, the reflex is called a short reflex. [4]
Type 2 diabetes (T2D), formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. [6] Common symptoms include increased thirst , frequent urination , fatigue and unexplained weight loss . [ 3 ]
The body requires a relatively constant input of glucose, a sugar produced upon digestion of carbohydrates, for normal functioning. Glucagon and insulin are among the hormones that ensure a normal range of glucose in the human body. [18] Upon consumption of a meal, blood sugar normally rises, which triggers pancreatic cells to
The flat line is the optimal blood sugar level (i.e. the homeostatic set point). Blood sugar levels are balanced by the tug-of-war between 2 functionally opposite hormones, glucagon and insulin. Blood sugar levels are regulated by negative feedback in order to keep the body in balance.
The leading cause of hyperglycemia in type 2 diabetes is the failure of insulin to suppress glucose production by glycolysis and gluconeogenesis due to insulin resistance. [39] Insulin normally inhibits glycogenolysis, but fails to do so in a condition of insulin resistance, resulting in increased glucose production. [ 40 ]
Fructose (/ ˈ f r ʌ k t oʊ s,-oʊ z /), or fruit sugar, is a ketonic simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. It is one of the three dietary monosaccharides, along with glucose and galactose , that are absorbed by the gut directly into the blood of the portal vein during digestion .
