Reactive hypoglycemia, postprandial hypoglycemia, or sugar crash is a term describing recurrent episodes of symptomatic hypoglycemia occurring within four hours [1] after a high carbohydrate meal in people with and without diabetes. [2] The term is not necessarily a diagnosis since it requires an evaluation to determine the cause of the ...
Improvement in blood sugar level and symptoms is expected to occur in 15–20 minutes, at which point blood sugar is measured again. [3] [2] If the repeat blood sugar level is not above 70 mg/dL (3.9 mmol/L), the hypoglycemic should consume another 10–20 grams of a carbohydrate and with remeasurement of blood sugar levels after 15–20 minutes.
In North America a mild episode of diabetic hypoglycemia is sometimes termed a "low" or an "insulin reaction," [4] and in Europe a "hypo", although all of these terms are occasionally used interchangeably in North America, Europe, Australia and New Zealand. A severe episode is sometimes also referred to as "insulin shock".
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 .
If blood sugar levels remain too high the body suppresses appetite over the short term. Long-term hyperglycemia causes many health problems including heart disease, cancer, [5] eye, kidney, and nerve damage. [6] Blood sugar levels above 300 mg/dL can cause fatal reactions.
Dysgeusia is also often associated with ageusia, which is the complete lack of taste, and hypogeusia, which is a decrease in taste sensitivity. [1] An alteration in taste or smell may be a secondary process in various disease states, or it may be the primary symptom .
Impaired fasting glucose is often without any signs or symptoms, other than higher than normal glucose levels being detected in an individual's fasting blood sample.There may be signs and symptoms associated with elevated blood glucose, though these are likely to be minor, with significant symptoms suggestive of complete progression to type 2 diabetes.
Long-term complications from high blood sugar include heart disease, stroke, diabetic retinopathy, which can result in blindness, kidney failure, and poor blood flow in the lower-limbs, which may lead to amputations. [1] The sudden onset of hyperosmolar hyperglycemic state may occur; however, ketoacidosis is uncommon. [4] [5]
