Hi, thanks for using healthcare magic It is possible to conceive with PCOS, it is just more difficult, but with the technology and procedures that exist today, conception is definitely possible. You are right in trying to lose weight , this would increase the chances of conception. It is easier to lose weight by modifying your diet because usually by altering a few things that are use calories can be reduced by 500 calories.It would take alot of exercise to achieve this same amount of calorie deficit. Exercise is important in general fitness and keeping weight off. To lose weight you would need to cut out all sodas and fruit drinks and use water instead. Use low carb fruits and vegetables as snacks. In terms of your other meals you can choose the low fat or low carb route.In the low carb route you would: Increase the amount of low carb fruits and/or vegetables that you use with your main meals and at the same time reduce the amount of carbohydrates to a minimum (pasta/rice/flour products/bread/biscuits/cereals/potatoes). There are lists of low carb foods available online. In the low fat route you would reduce fat used (fatty meats/frying/butter/certain oils/ high fat milk or cheeses or dressings/mayonaise), increase fruits and vegetables, use alot of water. Metformin has also been used in PCOS. This medication is used to reduce the insulin resistance associated with PCOS, help with weight loss and improve fertility.It is one of the most common drugs used in PCOS. You can consider speaking to your doctor about it. In addition, if with weight loss and metformin you still have difficulties, clomid can be used. This medication, again very widely available, helps with ovulation. If clomid does not work then there are other medications that assist with ovulation. You may want to consider visiting a fertility specialist. Hope this helps
