Hyperinsulinemia, or elevated blood insulin levels, is an endocrine disorder most often found in patients with Polyendocrine Metabolic Ovarian Syndrome (PMOS). PMOS, formerly known as PCOS, is characterized by irregular menstrual periods, hormonal imbalances, and the presence of an increased number of small follicles on the ovaries. PMOS occurs in varying in degrees. Some women with PMOS may also experience excessive hair growth, hair loss, acne, and obesity.
Hyperinsulinemia is believed to contribute to hormonal imbalance in the pituitary gland and ovary. This leads to an increased level of lutenizing hormone (LH). Increased levels of LH are then believed to cause ovulation disorders, menstrual irregularities and infertility.
