-
alias: FBG
-
glucose levels after not having calories for 8 hours
Insulin
-
source: Glucose
-
helps with glucose uptake
-
also has other functions (all cells have insulin receptors)
- eg. liver use insulin to help process glucose and fat
Conditions
Insulin Resistance
-
source: Glucose
-
potentially affects 88% of adults in the US
-
symptomps
- higher levels of insulin in blood
- insulin doesn't work as well in certain cells
- cells that still process insulin normally now get flooded with too much glucose
- this is what happens in polycystic ovarian syndrome (PCOS), most common cause of infertility in woman
- too much insulin causing ovaries to produce less estrogen
-
consequence
- heart disease
- diabetes
- infertility
- Alzheimer's
-
occurs when some cells don't respond to insulin
