Women who underwent dramatic weight loss after bariatric surgery had fewer pregnancy and delivery problems and fewer newborn complications than obese pregnant mothers, according to a recent study.

The investigation, which analyzed the data from 75 clinical studies, discovered that pregnant women who had undergone weight-loss surgery (laparoscopic adjustable band surgery) experienced fewer complications than obese women. In particular, 0 percent of weight-loss women suffered from gestational diabetes, versus 22.1 percent of obese women, and 0 percent of weight-loss women had pre-eclampsia (pregnancy-induced high blood pressure), versus 3.1 percent of obese women. Also, women with bariatric surgery had less weight gain than the others. (Read more about Weight-Loss Surgery Helps Obese Moms' Pregnancies, Newborns)

Stomach banding is an important weapon in the war chest of the bariatric surgeon - but it typically requires five incisions and a considerable recovery time.

But a new technique just coming into use needs just a single incision to accomplish the task of gastric banding, that is, tying off the top portion of the stomach so that food flow is restricted and slowed down. When the small, top part of the stomach is full, it signals the brain, which tells the body it's no longer hungry. This can lead to large reductions in weight for the morbidly obese, who are the only category of patients allowed to undergo the surgery.

To understand more about the mystery of obesity, it's important to understand how fat cells are born, nurtured and matured. And the enlightenment that will flow from understanding obesity may sweep away mysteries relating to the generation of cardiovascular disease and diabetes, which seem to be so much more prevalent among people who are obese.

So it was with delight that scientists greeted a recent study identifying precursor cells that develop into full-blown fat tissue. The research, performed on "skinny" mice genetically modified to have no fat deposits, showed that injecting one particular type of cell into the mice caused them to form fat.

Each year, it is estimated that 8% of pregnant women in the US develop gestational diabetes, where hyperglycemia and insulin resistance develop as a result of pregnancy. The childhood obesity rate has doubled in the last two decades and it is estimated that 7 million overweight or obese children will grow into overweight or obese adults.

A study in the September issue of Diabetes Care has found the risk of childhood obesity increases in line with the pregnant mother's blood sugar levels. The research team of Kaiser Permanent Center for Health Research analyzed records of nearly 9,500 mother-child pairs who were members of the organizations health plan through the years of 1995 and 2000. The evidence found that diabetes in pregnant women resulted in an 89 percent higher risk of the child becoming overweight and an 82 percent higher risk of the child becoming obese between the ages of 5 and 7 years.

Obesity is on the rise, and so are associated health risks like diabetes, high blood pressure, cardiovascular disease, and sleep apnea. Although once believed to be a risky and rare procedure, bariatric surgery is becoming a prevalent option for people who suffer from morbid obesity. Over 175,000 patients underwent bariatric surgery last year and the number is expected to grow this year. Although there are risks in undergoing these procedures, the surgery death rate has fallen over the years as the technique becomes more sophisticated and less invasive.

According to a study in the New England Journal of Medicine, if someone in a social network becomes obese, those closely connected to them have a greater propensity for becoming obese as well. The strongest demonstration of this effect occurs among friends, not within a family or among those sharing a household. There was no apparent consideration of groups of otherwise strangers who come together in organized settings for the purpose of weight loss. With some diet programs, social support has been shown to be beneficial. (Read more about Obesity May Be Contagious)
