A new study found that 10 percent of all gallbladder, kidney, liver, and
colon cancers could be attributed to excess weight.
A whopping 41
percent of uterine cancers were tied to obesity, according to the study
published today in The Lancet.
More than 36 percent of Americans are now considered obese, according to the U.S. Centers for Disease Control and Prevention. An additional 34 percent are considered overweight.
Cancer
The Lancet study of 5.4 million people found that every 1-point
population-wide increase in body mass index or BMI would result in 3,790
additional cancers each year.
That’s worrying, considering that the
average BMI in the U.S. has risen nearly 2.5 points for men and almost
four points for women since 1971, according to a 2013 study.
The National Cancer Institute estimates that obesity contributes to
34,000 new cases of cancer in men and 50,000 in women each year. But if
every adult reduced their BMI by 1 percent – a loss of roughly 2.2
pounds – about 100,000 new cases of cancer could be avoided, according
to the agency’s website.
Migraines
A study published in the journal Neurology revealed what a real headache carrying extra weight can be.
Johns Hopkins researchers surveyed nearly 4,000 people to find that the
higher their body mass index, the greater their chances were of having
episodic migraines. Those who were obese were 81 percent more likely to
experience at least 14 migraine headaches each month compared to people
who were a healthy weight. Obese women over the age of 50 suffered from
chronic headaches the most.
Infertility
Overweight women have a harder time getting pregnant. One Indian study
of 300 morbidly obese women found that over 90 percent of them developed
polycystic ovarian disease, a condition associated with infertility,
over a three-year period.
As with cancer, the association between obesity and infertility isn't entirely clear.
"Obesity is an inflammatory state and that alone might decrease
fertility," noted Dr. Marc Bessler, director of the Center for Weight
Loss and Metabolic Surgery at New York Presbyterian Hospital at Columbia
University Medical Center. "It may also be the result of hormone
changes produced by the fatty tissue."
Bessler said that many of his heavier patients experienced difficulty
getting pregnant. And many infertility clinics don't accept female
patients with high body mass indexes given their diminished chances of
conceiving. However, Bessler said some of his patients become pregnant
just months after weight-loss surgery once they had dropped a few
pounds.
Premature Birth
For heavier women who do get pregnant, the worries aren't over. A study
in the Journal of the American Medical Association found that obesity
increases a woman's chance of having a pre-term baby, especially when
her body mass index is 35 or higher.
The study's authors speculate that having too much fat may inflame and
weaken the uterine and cervical membranes. Whatever the reason, it can
have devastating effects. Premature birth is the leading cause of infant
death and long-term disabilities.
Sleep Disorders
Sleep and excess weight do not make good bedfellows. Nearly 80 percent
of older, obese Americans report having problems with sleep, an American
Sleep Foundation survey found.
Poor sleep contributes to a host of diseases including diabetes, heart
disease and, ironically, obesity itself. Numerous studies link short
sleep to expanding waistlines, including the Harvard Nurses' Study,
which found that those who slumbered less than five hours a night were
15 percent more likely to gain weight than those who enjoyed at least
seven hours of sleep.
Dr. Donald Hensrud, a nutritionist and preventive medicine expert in the
department of endocrinology, diabetes, metabolism and nutrition at the Mayo Clinic, said one of the most immediate health dangers for many obese people is sleep apnea, a condition in which a person gasps or stops breathing momentarily while asleep.
"Sleep apnea can be caused by increased fat around the neck area that
presses down and closes off the soft tissues of the airways while a
person is lying down, especially on his back," Hensrud said. "This means
the person does not get good quality sleep, has less oxygen in the
blood stream, and the heart has to work harder."
Bullying
Though fat people are often the butt of the joke, obesity stigma is no laughing matter.
A Yale study found that weight is the number one reason people are
bullied at any age and those who are bullied have lower self-esteem,
higher levels of depression and increased risk of suicide.
The main source of ridicule, according to the Yale researchers: Loved ones.
"More than 40 percent of children who seek treatment for weight loss say
they have been bullied or teased by a family member," said the study's
lead author, Rebecca Puhl. "When we asked obese women who stigmatized
them the most, 72 percent said it was someone in their family."
Puhl said discussions with loved ones about their burgeoning weight
often come across as judgmental and derogatory, even when intentions are
good. However, offering support and encouragement is the most effective
approach to help someone struggling to drop off pounds.
Difficulty Finding Doctors
The number two source of stigma, after loved ones?
Puhl said her studies have found that 67 percent of overweight men and
women report being shamed or bullied in the doctor's office. And 50
percent of doctors found that fat patients were "awkward, ugly,
weak-willed and unlikely to comply with treatment" while 24 percent of
nurses said they were repulsed by their obese patients.
A negative reception from a healthcare provider is especially
detrimental to obese people, Puhl stressed, because they already contend
with a greater number of health problems than average.
"Besides jeopardizing discussions between patients and healthcare
providers, someone who is obese is more likely to avoid the doctor
altogether even when they have a problem," she said.
However Puhl noted that the knife cuts both ways. Her studies reveal
that people are less apt to follow doctor's orders and more likely to
switch to a new provider if their physician is overweight.
