In recent years, the field of obesity medicine has experienced remarkable growth, evolving into a certified specialty since its establishment in 2011. This advancement has brought forth a diverse array of prescription medications designed to aid patients contending with the challenges of hormonal weight fluctuations associated with Polycystic Ovary Syndrome (PCOS). Here, we explore five prominent medications backed by substantial evidence.
Phentermine/Topiramate, extensively studied among PCOS patients, has demonstrated its efficacy in enhancing fasting blood glucose levels, oral glucose tolerance test outcomes, insulin sensitivity, and facilitating weight loss ranging from 7-10% over a span of 24 weeks.
Originally developed to address diabetes and insulin resistance, Liraglutide carries the added benefit of promoting weight loss in numerous patients. In an investigation involving PCOS patients and comparing Liraglutide, Liraglutide/metformin, metformin alone, and orlistat, Liraglutide emerged as the most impactful in reducing waist circumference. However, it’s important to note that Liraglutide might not be well-suited for patients with a history of gallbladder or pancreatic issues. Additionally, its cost can be substantial, sometimes exceeding $1000 per month due to limited insurance coverage.
Metformin, primarily intended for diabetes management, has undergone extensive research within the context of PCOS. Given the frequent association of PCOS with insulin resistance, metformin’s correction of this sensitivity offers multiple advantages. Insulin resistance is believed to influence sex hormone binding globulin (SHBG) levels, thereby affecting the overall amount of circulating testosterone. By rectifying insulin resistance, many patients have found that this medication contributes to weight loss. Furthermore, metformin boasts minimal risk of side effects and is cost-effective.
Extensive research has also been conducted on Orlistat, an older medication, specifically for women with PCOS. Studies have revealed its significant capacity to reduce weight, insulin resistance, cholesterol levels, and testosterone when compared to a calorie-restricted diet alone.
It is essential to recognize that the response to different medications can vary among individuals. Adjustments in dosage, switching medications, or allowing several weeks for observation may be necessary. Every individual’s body is unique, emphasizing the need for a tailored approach to selecting weight loss medications for PCOS patients.
