HI, thanks for using healthcare magic Bigomet (trade name for metformin) is commonly used in PCOS. It helps reduce the insulin resistance associated with this condition and may also help with weight loss. Weight loss would definitely help with PCOS. It is one of the most important parts of treatment of this condition and causes the symptoms to improve. In terms of achieving weight loss, there are different diet plans available and you can choose one that best suits you. The main ones are the low fat/low calorie diets and the low carbohydrate diet. In addition to choosing on of these plans, you would also need to increase your level of physical activity. I hope this helps
