Thanks for writing in.
Losing weight with PCOS
can be a challenge. Metformin
helps people with PCOS lose weight. It also helps regularize their cycles. I think we should be looking at moderate physical activity for 50 minutes daily 5 times a week. Including functional training twice a week and weight training
twice a week would also help immensely. Also, dietary modification, a far more important component needs to be done. Eat 5-6 small meals a day. Drink 5-6 litres of water and have your dinner by 7:30 pm. Also, you must never miss your breakfast. Breathing exercises including pranayama can help you get over the yawning. The following link should provide the details
I think a visit to a gynaecologist would be worthwhile
Hope this helps
