Pancreatic insulin1

Syndromes1
- The mechanisms responsible for insulin resistance syndromes include genetic or primary target cell defects, autoantibodies to insulin, and accelerated insulin degradation. (medscape.com)
Cells in the pancreas1
- In response, beta cells in the pancreas step up the secretion of insulin to deal with the blood sugar spike, facilitating glucose transport through cell membranes and lowering blood sugar. (vitalitymagazine.com)
Markers of insulin resistance2
- The small HDL related metabolites also correlated positively with markers of insulin resistance at postpartum. (springer.com)
- Although many clinical physiology and epidemiology studies show an association between obstructive sleep apnea (OSA) and markers of insulin resistance, no causal pathway has been established. (atsjournals.org)
Contribute to insulin resistance3
- Dietary factors are likely to contribute to insulin resistance. (wikipedia.org)
- Considerable weight gain is a common side effect of atypical antipsychotic medications, and is also one of the many factors that can contribute to insulin resistance. (sciencedaily.com)
- Excess weight, lack of exercise, and a family history of diabetes all contribute to insulin resistance. (sciencedaily.com)
Liver3
- Accumulation of triacylglycerol in skeletal muscles and in liver is associated with insulin resistance. (cambridge.org)

Blood glucose levels2
- Diminished effectiveness of insulin in lowering blood glucose levels requiring 200 units or more of insulin per day to prevent hyperglycemia or ketosis. (news-medical.net)
- Prolactin does not seem to mediate the improvement on insulin resistance markers and blood glucose levels related to breastfeeding. (bvsalud.org)
Measure insulin resistance1
- There are multiple ways to measure insulin resistance such as fasting insulin levels or glucose tolerance tests, but these are not often used in clinical practice. (wikipedia.org)
Cardiovascular3
- Previous observational studies showed that insulin resistance was associated with an increased risk of cardiovascular diseases. (bmj.com)
- Mechanism underlying the association of insulin resistance with cardiovascular diseases requires further investigation. (bmj.com)
- Sample size a clustering of specific cardiovascular risk for a population of 208 000 was determined factors whose underlying pathophysiology as 384, assuming a margin of error of 5%, is thought to be related to insulin resistance with 95% confidence. (who.int)
Practice2
- How might these results change the focus of research or clinical practice? (bmj.com)
- The adoption of medical AI devices in clinical practice is still in its infancy, with uneven usage across procedures and locations in the USA, which underscores the inequities in its real-world implementation. (nature.com)
Pancreas4
- Insulin is released by the pancreas in response to carbohydrates consumed in the diet. (wikipedia.org)
- The pancreas tries to keep up with the demand for insulin by producing more. (sciencedaily.com)
- Eventually, the pancreas cannot keep up with the body's need for insulin, and excess glucose builds up in the bloodstream. (sciencedaily.com)
- But when blood sugar levels are chronically elevated, the pancreas becomes stressed and progressively more dysfunctional, unable to produce enough insulin to deal with the spikes. (vitalitymagazine.com)
Carbohydrates2
- Anyone whose diet is high in sugar and refined carbohydrates will eventually face insulin resistance. (vitalitymagazine.com)
- Out of those three macronutrients, carbohydrates will spike glucose and insulin the most. (apple.com)
Plasma glucose3
- This new ability to measure both plasma glucose and insulin concentration allowed the development of oral glucose tolerance testing ( 7 ) and the glucose clamp techniques ( 8 ). (basicmedicalkey.com)
- 1 Similar direct measurements have been accepted as estimates of insulin resistance including the frequently sampled intravenous glucose tolerance test, the steady state plasma glucose method, the oral glucose tolerance test, and the homeostatic model assessment (HOMA) 1 . (drugtopics.com)
- [ 2 ] The patient is instructed to fast, and plasma glucose, insulin, proinsulin, and C-peptide levels are measured every 6 hours until the plasma glucose level is less than 65 mg/dL, after which the testing frequency is increased to every 1-2 hours. (medscape.com)
Mechanisms2
- In this article, the molecular and cellular mechanisms underlying defective brain insulin signaling in AD are discussed, with emphasis on evidence that Alzheimer's and diabetes share common inflammatory signaling pathways. (jci.org)

Amount of insulin2
- In states of insulin resistance, the same amount of insulin does not have the same effect on glucose transport and blood sugar levels. (wikipedia.org)
- Thus, an abnormally large amount of insulin is required to achieve a biological response. (isciii.es)
