Is Fat the New Normal?

Are Americans Really Getting Fatter?

The rate of obesity has climbed dramatically in the past 20 years: A third of adults are obese today, compared to 23% in the late 1980s. But this trend may have reached a plateau. According to a new study in the Journal of the American Medical Association, the obesity rate has not changed significantly in the past few years.

That’s no reason to become complacent, Kushner says. “The prevalence of obesity is leveling off, but it’s leveling off at flood stage. So we need to turn that around."

Is Weight Gain Contagious?

How did we get to that “flood stage" of obesity? Maybe you should look around you.

“Our work suggests that weight gain spreads in social networks," says Christakis, who has researched the spread of obesity.

His findings, published in The New England Journal of Medicine in 2009, show that your odds of becoming obese rise by 57% if you have a friend who becomes obese and by 40% if your sibling becomes obese."We’re social animals," Christakis says. “We’re influenced by the choices and actions and appearance and behaviors of those around us."

In short, our social contacts — the people in our lives — have a big influence on what we eat, how much we exercise, and how we judge our own appearance. This may help explain why obesity rates are not the same throughout the country. In fact, there are what might be called obesity hotspots.

Obesity Hotspots

Jana Gordon Bunsic, DO, has seen evidence of this first-hand in her practice. She’s a board-certified family physician and clinical nutritionist in Morristown, Tenn. – a town in a state with one of America’s highest obesity rates.

“Upon moving my family and my medical practice to east Tennessee, I was immediately surprised by the prevalence of obesity in the area," says Bunsic, who used to live in south Florida. She cites a culture that’s fond of “biscuits and gravy," as well as too little exercise. “The society is quite rural, and few people walk or ride bikes from place to place."

With obesity being so common, Bunsic finds her patients have a skewed idea of what’s normal. “A 16-year-old patient came in with his mother the other day," she recalls. “By following my recommendation, he had lost 45 pounds… His mother was very concerned he was starting to become too thin" even though he was still overweight by medical standards.

Changing Perceptions

Skewed perceptions are not confined to Tennessee.

“It’s taking more and more weight as time goes by for people to judge themselves heavy," Christakis says. In a study using government data, he found that obese people generally knew they were obese 20 years ago. That’s not necessarily the case anymore. In 2007, a National Consumers League survey showed that although 34% of adult survey participants were obese, only 12% said they had ever been told that by a health care professional.

Contributing to these changing perceptions is a fashion trend known as vanity sizing. Manufacturers have made clothing sizes more forgiving over the years. “This is making women feel good about themselves," Kushner says, “but the bad thing is it’s supporting the weight increase in the population."

Pros and Cons of a New Normal

Kushner sees two positives in society’s changing views of weight. One is that overweight people “don’t tag so much of their self-esteem to weight," Kushner says. The other is that women of a healthy weight are less likely to see themselves as fat. With so much more of the population being truly overweight, those in the healthy category may feel slim by comparison.

But Kushner cautions that there is a downside, particularly for the obese. If people don’t recognize that they have a problem, they’ll be less motivated to lose weight, he says. And although the social norms may be changing, the health risks of obesity are not.

Health Risks of Obesity

“It’s clear that being overweight is bad for your health," Christakis says. This does not mean that everyone who is overweight will develop health problems, but the risks are well documented. Excess weight has been linked to diabetes, arthritis, heart disease, and some forms of cancer. And last year, a study found that weighing a third more than your ideal weight could take three years off your life.

“Many [patients] intuitively know their weight is a big part of their diabetes, hypertension, lower extremity swelling, and feeling poorly," Bunsic says, “but they have never had a doctor tell them that their weight was a root cause." To turn the situation around, she says doctors should counsel patients about the dangers of being overweight and help them develop accurate perceptions of what is normal.

Christakis agrees, but he says health professionals must handle the issue of weight delicately. “People could tell their patients, ‘When you make an effort to lose weight, it doesn’t just benefit you.'" The bottom line: Healthy habits tend to spread among social contacts. So when you make a positive change in your life, it may also affect the people you care about.

Is Fat The New Normal?

Imagine being 6’0 in Asia, you would obviously stand out in a crowd – maybe you would even be self-conscious. But step into North America or Europe, suddenly, you don’t seem so tall anymore. Your above-average height feels normal.

The same scenario — but with weight, not height — may be happening throughout the world. The Ministry of Health Malaysia (MoHM) found that 2 in 3 Malaysians are overweight or obese. 

Now that the average body weight tends toward plump rather than svelte, the perception of what’s normal may be sliding. And that may have health consequences that are flying under the radar.

The New Normal

The average American is 23 pounds heavier than his or her ideal body weight. If we equate “normal" with average, it’s not much of a stretch to say it’s normal to be fat.

“For children and for many adults who are overweight, they are starting to perceive themselves as the new normal," says obesity expert Robert F. Kushner, MD, MS. Overweight people may dismiss their weight, he tells WebMD, because they feel “everyone else looks exactly the same." Kushner is a professor at Northwestern University’s Feinberg School of Medicine and clinical director of the Northwestern Comprehensive Center on Obesity.

“It’s quite clear that people are changing their idea of what an acceptable body size is," says Nicholas Christakis, MD, PhD, of Harvard Medical School. As the average body weight goes up, there’s more acceptance of heavier body types. This, in turn, clears the path for even more people to put on weight, says Christakis, who is the co-author of Connected: The Surprising Power of Our Social Networks and How They Change Lives.

Symptoms of Hirshsprung’s Disease

Symptoms vary with age. Approximately 80% of children with the disease have symptoms in the first six weeks of their lives. However, children who only have a short segment of the intestine that lacks normal nerve cells may not exhibit symptoms for several months or years. For these children, their primary symptom is constipation.

Each child may experience symptoms differently, but some signs and symptoms to look out for include:

  • No bowel movements: If the newborn does not develop a stool or meconium within the first few days, you should be concerned. 
  • Bloody diarrhea: Hirschsprung’s disease may also induce enterocolitis, a life-threatening inflammation of the colon, as well as extreme diarrhea and gas.
  • Abdominal distention (stomach bloating)
  • Gradual onset of vomiting: Children with Hirschsprung’s disease may have green or brown colored vomit
  • Fever
  • Constipation or failure to pass regular bowel movements

Children who don’t have early symptoms may experience the following signs of Hirschsprung’s disease as they get older:

  • Constipation that becomes worse with time: Hirschsprung’s disease can cause chronic (ongoing) constipation in older children.
  • Loss of appetite
  • Fatigue
  • Delayed growth
  • Passing small, watery stools
  • Abdominal distention

Diagnosis of Hirshsprung's Disease

If your child exhibits these signs, you can contact your doctor right away. Hirschsprung's can be confirmed by a series of tests:

  • A contrast enema: It's also known as a barium enema, named for the compound used in the pigment used to coat and highlight the insides of the body's organs. Your child will be laid face down on a table while the dye is injected into the intestines through a tube from the anus. There is no need for anaesthesia (a drug that numbs or blocks pain). On X-rays, the pigment helps the doctor to see problem regions. The contrast enema is part of a series of studies on the gastrointestinal tract known as a “lower GI series."
  • An abdominal X-ray: This is a typical X-ray that the technician will take from various angles. Your doctor will be able to see if anything is obstructing your intestines.
  • A biopsy: A tiny amount of tissue from your child's rectum would be taken by your doctor. Hirschsprung's disease can be examined in the tissue. The doctor can use anaesthesia depending on your child's age and height.
  • Anorectal manometry: This test involves inflating a small balloon inside the rectum to see how the muscles react. Only older children are subjected to this evaluation.

Treatment of Hirshsprung's Disease

Hirschsprung's disease is a life-threatening illness. However, if detected soon, it can be able to assist your child in leading a relatively normal life.

Usually, surgeons will perform one of two forms of surgery:

  • Pull-through procedure: This procedure involves removing the section of the large intestine that contains the missing nerve cells. The remainder of the intestine is then immediately connected to the anus.
  • Ostomy surgery: This technique binds the intestine to a body opening. The doctor then puts an ostomy bag on the outside of the opening to store intestinal waste. Ostomy surgery is also used as a temporary solution before the infant is ready for the pull-through operation.

Any children can develop constipation, diarrhoea, or incontinence following surgery (lack of control over bowel movements or urination).

Enterocolitis may affect a small number of people. Rectal bleeding, fever, vomiting, and a swollen belly are all symptoms. Take your kid to the doctor right away if anything happens.

However, with good care, including a healthy diet and lots of water, these symptoms can ease, and most children should be able to resume regular bowel movements after a year of treatment. Other children will have gastrointestinal problems on and off throughout their lives. Hirschsprung's condition is a lifetime problem and can be controlled because it is congenital.

Risk Factors of Hirshsprung's Disease

Factors that may increase the risk of Hirschsprung's disease include:

  • Having a sibling who has Hirschsprung's disease. Hirschsprung's disease can be inherited. If you have one child who has the condition, future biological children could be at risk.
  • Being male. Hirschsprung's disease is more common in males.
  • Having other inherited conditions. Hirschsprung's disease is associated with certain inherited conditions, such as Down syndrome and other abnormalities present at birth, such as congenital heart disease.
