phentermine and Polycystic Ovary Syndrome

phentermine has been researched along with Polycystic Ovary Syndrome in 1 studies

Phentermine: A central nervous system stimulant and sympathomimetic with actions and uses similar to those of DEXTROAMPHETAMINE. It has been used most frequently in the treatment of obesity.

Polycystic Ovary Syndrome: A complex disorder characterized by infertility, HIRSUTISM; OBESITY; and various menstrual disturbances such as OLIGOMENORRHEA; AMENORRHEA; ANOVULATION. Polycystic ovary syndrome is usually associated with bilateral enlarged ovaries studded with atretic follicles, not with cysts. The term, polycystic ovary, is misleading.

Matsuda Sensitivity Index Derived From the OGTT(SI OGTT)

The SI IOGTT is a measure of peripheral insulin sensitivity derived from the values of Insulin (microunits per milliliter) and Glucose (milligrams per deciliter) obtained from the OGTT and the corresponding fasting values. SI (OGTT) = 10,000/ [(G fasting x I fasting) x (G OGTTmean x I OGTTmean)], where fasting glucose and insulin data are taken from time 0 of the OGTT and mean data represent the average glucose and insulin values obtained during the entire OGTT. The square root is used to correct for nonlinear distribution of insulin, and 10,000 is a scaling factor in the equation. The higher value, the more sensitive to insulin. (NCT02635386)

Oral Disposition (Insulin Sensitivity-insulin Secretion) Index

An estimation of β-cell compensatory function, the insulin secretion-sensitivity index (IS-SI) will be derived by applying the concept of the oral disposition index to measurements obtained during the 2-h OGTT and calculated as the index of insulin secretion factored by insulin sensitivity (ΔINS/ΔPG 30 x Matsuda SIOGTT) from the OGTT. A higher score shows improved pancreatic insulin responsiveness relative to resistance. (NCT02635386)
