Do multiple pregnancies present higher risks than singleton pregnancies?

Do multiple pregnancies present higher risks than singleton pregnancies?

Absotutely: Every risk in a singleton pregnancy is higher with twins. Risk of miscarriage, genetic abnormalities in a child, and even though small, the risk of one baby not surviving. Risks to mother of hypertension and diabetes are much higher. And the risk of early delivery is much higher. Even though twins generally do well, many twins do not. So it is always medically preferable to have a single pregnancy. ...Read more

Pregnancy 15 week, ultrasound report.,.. Turner syndrome with cystic hygroma and hydrops fetalis....., your advise required?

Pregnancy 15 week,  ultrasound report.,.. Turner syndrome with cystic hygroma and hydrops fetalis....., your advise required?

Your decision: in the end. These findings in the first trimester usually carry a poor outlook for survival of the baby but there have been many reports of resolution of both cystic hygroma and hydrops as pregnancy progresses. Turner syndrome will always be there. I cannot decide for you but suggest you consider re-evaluating by ultrasound in 3-4 weeks should you decide to continue the pregnancy, you will then know more about the prognosis for the baby and any associated problems such as congenital heart defect etc. see:http://www.turnersyndrome.org/#!child/c4ff ...Read more

Will a vanishing twin (lost at 7 weeks) affect the results of first trimester Down's syndrome blood testing?

Will a vanishing twin (lost at 7 weeks) affect the results of first trimester Down's syndrome blood testing?

Unlikely: These tests rely on the active production of various markers in the blood and so a demised twin this early on will be unlikely to affect the test. These tests however, should be interpreted in the setting of a screening ultrasound to help better understand the risk. That being said, no test is ever 100% accurate, though they are useful. Consultation with a genetic counselor will help. ...Read more
