Summary Introduction
To examine: Whether the statement “Excess visceral fat and insulin resistance are shared characteristics among women with PCOS” is true or false.
Introduction: Polycystic ovary syndrome (PCOS) is connected with hormones related problems that are seen in some women in their childbearing years (ages 15 to 44). 2.2 to 26.7 % of women of this age are reported to have PCOS, most of them not having any relatable information about the condition. PCOS influences the ovaries, and estrogen and progesterone produced by the conceptive organs that manage the menstrual cycle. Ovulation is the release of an ovum from a mature follicle. The hormones luteinizing hormone (LH) and follicle stimulating hormone (FSH) control ovulation. FSH allows the ovary to create a follicle egg present in a sac and after that the egg is triggered by the LH and then the ovary discharges a developed egg.

- Daniel is a 52-year-old male with a history of obesity and diabetes. He had gastric bypass surgery 6 years ago and has been maintaining normal blood glucose levels and a BMI of 25 for the last 4 years. Daniel was able to stop taking medication for his diabetes but still takes a daily multivitamin. He has had symptoms of Irritable Bowel Syndrome intermittently for 6 months, including abdominal pain and constipation. Within the last week, he has developed new symptoms that are more severe than the abdominal pain in the past. Daniel’s pain radiates into his groin and interior to the ribs on his right side. The pain fluctuates in intensity but is so severe that it’s debilitating at times.
