Early Birth For Mom Who Lost 42 Lbs to Morning Sickness

Fiona Shaw promised she would eat healthy when she discovered she was pregnant.

She told her boyfriend she would give up fast food and eat fresh fruit and vegetables instead.

But 28 weeks into her pregnancy, Shaw’s morning sickness, also known as hyperemesis, was so bad that she lost 42 pounds and was forced to have an emergency Caesarean section, reports the U.K.'s Daily Mail.

Dr. Manny Alvarez, managing editor of health for FOXNews.com, said such a dramatic weight loss in a pregnant woman is almost unheard of.

"I have never seen anything like this and I deal with a lot of women with hyperemesis; it's a very common condition in the first trimester of pregnancy," said Alvarez, who specializes in high-risk pregnancies and is chairman of the Department of Obstetrics and Gynecology, and Reproductive Science at Hackensack University Medical Center in New Jersey.

Before the C-section, Shaw, 24, of Rotherham, England, was admitted to the hospital with dehydration and blurred vision. Doctors gave her medicine to combat the nausea, but to no avail, the Daily Mail reported.

Alvarez said one of the main concerns with morning sickness is dehydration and a loss of nutrients, both of which may affect the development of the baby. "Certainly if you lost this kind of weight and had a small frame to begin with, you could jeopardize the pregnancy and the health of the baby," he said.

An ultrasound at 28 weeks showed Shaw’s baby girl was not gaining any weight and had an abnormal heart rate. That’s when doctor’s decided to deliver the baby more than two months before her due date.

Baby Tianna was born weighing a meager two pounds, five ounces. Tianna’s underdeveloped lungs caught several infections, but she survived.

"Not knowing all of the facts, my questions would be, was this women seen early on and did early intervention occur and fail," Alvarez added, " or was she suffering in silence and only sought medical attention when things got out of control."

Today, baby Tianna weighs 15 pounds and both she and her mother are healthy.
