Anybody can be overweight, but most people do not recognize the far-reaching effects that this can have throughout a person’s life. For instance, you might unconsciously think that an overweight teenager or child is more likely to enjoy a healthy adulthood if they lose the excess weight before they turn 25 or 30. Unfortunately, this is not the case.
According to recent research findings, overweight teenagers are twice as likely to develop colorectal cancer once they hit middle age.
Researchers tracked the health of more than 239,000 men who had been conscripted into the Swedish army between the ages of 16 and 20 from 1969 to 1976.
At the time of conscription, around 12 percent of the men were underweight, more than 80 percent were of normal weight and five percent were moderately overweight.
Of the remainder, 1.5 percent were very overweight—with a body mass index of between 27 and nearly 30—and one percent were obese, with a BMI of more than 30.
The conscripts were regularly checked for colorectal cancer for next 35 years, during which 885 cases —501 colon cancers and 384 rectal cancers—were detected.

The study was carried out by researchers from the Harvard School of Public Health. It was unique because it was the first large-scale study examining the impact of being overweight in teenagers.
A later observational study carried out by doctors at the Brigham and Women’s Hospital in Boston. In this particular study, researchers found that women that were overweight when they were 18 years old were at greater risk of sudden cardiac death, regardless of their weight later on.
The study, in JACC: Clinical Electrophysiology, followed 72,484 women, generally healthy at the start, from 1980 to 2012. Over the period, 454 suffered sudden cardiac death.
Compared with those with a body mass index of 21 to 22.9 at age 18, those with a B.M.I. of 23 to 29.9 had a 33 percent higher risk for sudden cardiac death; those with a B.M.I. of 30 to 35.9 had twice the risk; and those with a B.M.I. higher than 35 nearly four times the risk. These risks remained after adjusting for age, smoking, physical activity, hypertension, diabetes and many other variables. A body mass index of 18.5 to 25 is generally considered normal. Via NY Times
Babies born to overweight mothers also tend to be at increased risk for being overweight and developing other weight-related health problems as well. In fact, the problem is so serious that researchers are now looking for ways to prevent babies born to obese mothers from developing the problem.
One group of researchers, for instance, want to give overweight pregnant women a hormone pill that will prevent their babies from being born obese. This medication is meant to be administered to the babies while in the womb, an approach that is raising quite the controversy. However, these researchers believe that this could improve the unborn child’s health even into his or her adulthood.
The controversial idea comes amid growing concern about the toll the obesity crisis is having on pregnancies.
Around half of British women of childbearing age are overweight and more than 15 per cent of pregnant women are obese.
Their babies are more likely than average to be fat themselves as children and are at higher risk of diabetes and heart disease in adulthood.
As a result, many experts believe that improving conditions in the womb could have lifelong benefits to health. Via Daily Mail
This theory has actually been tested in the US, where researchers gave pregnant obese mice a hormone called adiponectin. This hormone, which helps to process sugar, has been found to be low among overweight women. As expected, the mice that were treated with the hormone gave birth to pups of normal weight, while those that were not treated gave birth to overweight pups.
Critics of this approach argue that an easier and safer option would be for the mothers to simply diet. The researchers argue that based on realistic experience, many people do not lose weight based on the advice and assistance they receive on diet and exercise, leaving unborn children vulnerable.
What is evident here is that being overweight opens the door for a host of potential problems that you would much rather avoid. The best time to start dealing with weight problems is now.
