The esophagus is the tube that carries food from the throat to
the stomach. Achalasia is a serious condition that affects your esophagus. The lower
esophageal sphincter (LES) is a valve that closes off the esophagus from the
stomach. If you have achalasia, your LES fails to open up during swallowing,
which it’s supposed to do. This leads to a backup of food within your esophagus.
This condition can be related to damaged nerves in your esophagus. It can also
be due to damage of the LES.
According to the Cleveland Clinic, achalasia affects about 3,000
people in the United States every year.
Achalasia can happen for different reasons. It can be difficult
for your doctor to find a specific cause. This condition may be hereditary, or
it may be the result of an autoimmune condition, which occurs when your body’s
immune system mistakenly attacks healthy cells in your body. The degeneration
of nerves in your esophagus often contributes to the advanced symptoms of the
Other conditions can cause symptoms similar to achalasia. Cancer
of the esophagus is one of these conditions. Another cause is a rare parasitic
infection called Chagas’ disease. This disease occurs mostly in South America.
Is at Risk for Achalasia?
Achalasia usually occurs later in life, but it can also occur in
children. Individuals who are middle-aged and older are at higher risk for the
condition. Achalasia is also more common in people with autoimmune disorders.
Are the Symptoms of Achalasia?
People with achalasia will often have trouble swallowing or feel
like food is stuck in their esophagus. This is also known as dysphagia. This
symptom can cause coughing and raises the risk of aspiration, or inhaling or
choking on food. Other symptoms include:
- pain or discomfort in your chest
- weight loss
- intense pain or discomfort after eating
You might also have regurgitation or backflow. However, these can
be symptoms of other gastrointestinal conditions such as acid reflux.
Is Achalasia Diagnosed?
Your doctor might suspect you have achalasia if you have trouble
swallowing both solids and liquids, particularly if it gets worse over time.
Your doctor may use esophageal manometry to diagnose achalasia.
This involves placing a tube in your esophagus while you swallow. The tube
records the muscle activity and makes sure your esophagus is functioning
An X-ray or similar exam of your esophagus may also be helpful in
diagnosing this condition. Other doctors prefer to perform an endoscopy. In
this procedure, your doctor will insert a tube with a small camera on the end
into your esophagus to look for problems.
Another diagnostic method is a barium swallow. If you have this
test, you’ll swallow barium prepared in liquid form. Your doctor will then
track the barium’s movement down your esophagus through X-rays.
Is Achalasia Treated?
Most achalasia treatments involve your LES. Several types of
treatment can either temporarily reduce your symptoms or permanently alter the
function of the valve.
The first line of treatment is often oral medications. Nitrates
or calcium channel blockers can help relax the sphincter so food can pass
through it more easily. Your doctors might also use Botox
to relax the sphincter.
To treat achalasia more permanently, your doctors can either
dilate the sphincter or alter it. Dilation typically involves inserting a
balloon into your esophagus and inflating it. This stretches out the sphincter
and helps your esophagus function better. However, sometimes dilation tears the
sphincter. If this happens, you may need additional surgery to repair it.
Esophagomyotomy is a type of surgery that can help you if you
have achalasia. Your doctor will use a large or small incision to access the
sphincter and carefully alter it to allow better flow into the stomach. The
great majority of esophagomyotomy procedures are successful. However, some
patients have problems afterward with gastroesophageal reflux disease (GERD).
If you have GERD, your stomach acid backs up into your esophagus. This can
Is the Long-Term Outlook?
The outlook for this condition varies. Your symptoms might be
mild, or they may be severe. Treatment can be highly successful. Multiple
treatments are sometimes necessary.
Surgery may be necessary if a dilation procedure doesn’t work the
first time. Usually, the chance of success decreases with each successive
dilation. Therefore, your doctor will probably seek alternatives if several
dilations are unsuccessful.
percent of patients who have surgery get some relief from symptoms.
However, you may develop some complications. These include issues related to
tearing of the esophagus, acid reflux, or respiratory conditions caused by food
traveling up your esophagus and into your windpipe.
