hello, The ultrasound picture suggests that it is PCOD (polycystic ovarian disease). Its exact cause is not very well known in medical science ,most common causes are hormonal imbalances. You also need to get your thyroid hormone checked as it may also be an adding factor to the condition of your ovaries. it is serious because it effects one s fertility and the body also becomes resistant to insulin(which means your blood sugar rises despite of enough insulin) But to decrease your anxiety I would like tell you that it is very common and easily treatable. I would like to suggest you to keep a check on your body wt(BMI){I dont know how much you weigh, but mostly females who are obese suffer from this} If you have any more queries feel free to ask, Regards.
