If science doesn't lie, then obesity is unhealthy, expensive and it's a
rapidly growing problem. A study by government think-tank, Foresight,
suggests that half of Britons will be overweight by 2012. As the figures
rise, so do the associated health problems and accompanying medical
costs, estimated to be at nearly £4 billion annually in the UK. With
more than 24% of Brits currently obese, it's not going to stop anytime
soon. Let's start by talking about what it means to be overweight.
Everybody has a healthy weight range, but if you're outside of your
respective range, there can be significant physical consequences. The
degree to which you exceed the range determines whether you are
"overweight" or "obese.” Health practitioners say that weighing more
than 20% above your specified range is obese, while "overweight" is less
than 20% (but a number above 25 on Body Mass Index). While being obese
is associated with greater complications, being overweight can hold an
equal number of dangers.
We've established what it means to be overweight, so now let's discuss the specific dangers of being overweight.
Being overweight causes heart disease
The more weight you are packing, the greater your risk of an early death. Heart attacks are a leading cause of death for British men. The link between extra weight and an increased heart attack risk lies
in how the body responds to an increased fat intake. Naturally, the body
maintains a steady level of water, carbs, fat, and protein, along with
vitamins and minerals.
A higher overall fat concentration increases sodium levels and ups
cholesterol and triglyceride fats in your bloodstream. This consequence
is especially bad news because HDL cholesterol, a known risk-reducer of
heart disease, is replaced by "bad cholesterol.” The end result can be
coronary heart disease, which can lead to heart attacks.
Being overweight causes cancer
Hormones are the key link between an overweight person and an increased risk of cancer. The
New England Journal of Medicine
published a study that concluded that virtually all forms of cancer are
more prevalent in people with a higher body mass. Body mass wasn't only
linked to new cancer cases; it was also linked to cancer survival
rates, which were lower for heavier people. To solidify this argument,
The New England Journal of Medicine also pointed out that 15% of cancer deaths were tied to being overweight. These statistics are alarming, but how exactly does excessive weight
cause cancer? With increased body weight, the adipose fat tissue can
offset the body's natural hormonal balance, making the body an easier
host for tumours. Cancer is also related to the placement of fat on the
body. For example, a high amount of abdominal fat carries a greater risk
of colon cancer, and obesity-linked gastric reflux increases the
chances of esophageal cancer.
It sounds daunting, but the good
thing to know is that increased physical activity and a proper diet are
known to reduce cancer risks, so anyone can make a change for the
better.
Being overweight causes gallstones
The exact link between body
weight and gallstones isn't definitive, but gallstones do show up more
in overweight people, with the risk of developing gallstones being up to
seven times higher than for people of average weight. Gallstones are
firm particles in the gallbladder that lead to abdominal pain and
nausea. Although they aren't on the same scale of trouble as heart
disease and cancer, they can still require surgery, with the removal of
your entire gallbladder being the most effective procedure.
The information linking gallstones to body weight is based on the
composition of gallstones, which are made of bile pigments and cholesterol. The cholesterol component is based on excess cholesterol that the body doesn't need. Comparative studies between diets
show higher occurrences of gallstones in diets that are high in animal
fat and sugar and low in fibre and vegetable fat. The automatic reaction
to the gallstone scare might be to go on a swift diet, but losing
weight quickly can also increase your chances of developing them. A
better bet is a gradual weight loss, more exercise and an increase of
Vitamin C in your diet.
Being overweight causes strokes
Strokes remain among the top
five leading causes of death. When there’s an interruption in the
brain's blood supply, what follows is an immediate life-threatening risk
to the person in question. While there are many other risk factors in
play, strokes have also been linked directly to obesity and being
overweight, specifically where body mass is concerned. The
Archives of Internal Medicine
published a study showing that people who are overweight by 20% or less
carry a 50% increased probability of suffering a stroke. The study also
explained that being more than 20% overweight carried a risk that was
twice as high. Did you know that being overweight also puts you at risk of suffocation?
