What causes heartburn Rusha Modi

Just between your chest and abdomen

is where you’ll find one of the most
important muscles

you probably didn’t know you had:

the lower esophageal sphincter, or LES.

When functioning properly,

this ring of tissue plays a crucial
role in helping us eat.

But when the LES malfunctions,

it becomes the main player in heartburn

–a searing, sometimes sour-tasting
chest-spasm

that many people will experience
at some point in their lives.

We know that humans have
been battling heartburn

for hundreds, if not thousands of years.

But recently the incidence has risen,

making it a common stomach
complaint worldwide.

When the symptoms of heartburn become more
more regular and intense

—such as twice a week or more–

it’s diagnosed as Gastroesophageal
Reflux Disease, or GERD.

But what causes this problem,

and how can it be stopped?

Heartburn starts in an area called

the gastroesophageal junction,
where the LES resides.

This smooth, muscular ring of the LES

is moderated by an intricate
tree of nerve roots

that connect to the brain,
the heart, and the lungs.

After food enters the stomach
from the esophagus,

the muscle’s task is to stop it

from surging back up again.

The LES contracts, squeezing
the stomach entrance

and creating a high pressure zone

that prevents digestive acids
from seeping out.

But if the LES relaxes at the
wrong moment or gradually weakens,

it becomes like a faulty, ill-fitting lid,

causing the area to depressurize.

That allows burning stomach acid–

and even chunks of food–to spurt into the

esophagus, sometimes going
as far up as the mouth.

The cause of all this internal drama

has long been put down to diet.

Foods like caffeine and peppermint contain

ingredients that may have a
relaxing affect on the LES,

which makes it incapable of doing its job.

Other acidic foods,
like citrus and tomatoes,

can worsen irritation of the esophagus

when they leach out with stomach acid.

Carbonated beverages can similarly

bubble up in the stomach,

forcing open the valve.

But researchers have discovered
that food isn’t the only trigger.

Smoking poses a risk, because the nicotine
in cigarettes relaxes the LES.

Consuming excessive amounts of alcohol

may have a similar effect.

Pregnant women often experience
more heartburn

due to the pressure of a growing baby
on their stomachs.

and the levels of certain hormones
in their bodies.

Obesity can cause hernias that disrupt

the anti-reflux barrier of
the gastroesophageal junction

that normally protects
against heartburn.

Numerous medications,
including those for asthma,

high blood pressure, birth control,
and depression

can also have unintended
effects on the LES.

An occasional bout of heartburn isn’t

necessarily something to worry about.

But, if heartburn starts happening regularly,

it can weaken the LES muscle over time,

letting more and more acid escape.

And if it goes untreated,

this can cause bigger problems.

Over time, constant acid
leakage from heartburn

may form scar tissue which narrows the

esophageal tube, making it
harder to swallow food.

Ongoing reflux can also damage the cells

lining the esophagus–a rare
condition called

Barrett’s esophagus, which can elevate

the risk of esophageal cancer.

Luckily, heartburn is often treatable with

a range of medicines that can help

neutralize or reduce stomach acid.

In extreme cases, some people have surgery

to tighten the LES to
minimize their distress.

But we can often stop heartburn

before it reaches that point.

Reducing the consumption
of certain foods,

not smoking, and maintaining
a healthy weight

can all dramatically reduce reflux.

With proper care we can
help our LES’s keep

the chemical fountain of
our stomachs in proper order

and avoid having to feel the burn.
