Achalasia Cardia

Achalasia cardia is a rare condition that affects the esophagus, the tube that carries food from your mouth to your stomach. It makes swallowing difficult and can cause discomfort. The lower esophageal sphincter (LES) is a muscular ring that opens to allow food and liquid to pass into the stomach and then closes to prevent stomach acid from flowing back into the esophagus.

In people with achalasia, the LES remains tightly shut, making it harder for food and liquid to pass into the stomach. Over time, this leads to food accumulation in the esophagus, causing difficulty swallowing (dysphagia) and other symptoms.

The exact cause of achalasia cardia isn’t completely understood, but researchers believe it occurs due to the gradual loss of nerve cells in the esophagus, particularly those controlling the muscles of the LES. Without proper nerve signals, the LES remains contracted.

Several factors might contribute to the nerve damage leading to achalasia, such as:

● Autoimmune Response: The immune system might mistakenly attack the nerves in the esophagus.

● Infections: Some viral infections, like the herpes virus, have been linked to the development of achalasia.

● Genetics: While rare, a family history of achalasia could increase the risk.

Symptoms of achalasia commonly include:

● Difficulty Swallowing (Dysphagia): This is the most common symptom. You may feel like food or liquids are stuck in your throat or chest.

● Regurgitation: Undigested food or liquid may come back up into the mouth, especially when lying down.

● Chest Pain: Some people experience discomfort or pain in the chest, which can mimic heart pain.

● Weight Loss: Difficulty eating may lead to unintentional weight loss and malnutrition.

● Heartburn: Although heartburn is more common in acid reflux, some achalasia patients also report it.

● Coughing at Night: Food backing up into the esophagus can cause coughing or choking, particularly during sleep.

If you experience persistent swallowing issues, it’s essential to consult a doctor. Early diagnosis can prevent complications like malnutrition and esophageal damage.

Achalasia symptoms can resemble other digestive issues, such as acid reflux or esophageal cancer. To confirm a diagnosis, your doctor may recommend the following tests:

● Esophageal Manometry: This is the most definitive test for achalasia. A thin tube is inserted into the esophagus to measure muscle function and LES relaxation.

● Barium Swallow Test: You’ll swallow a liquid containing barium (a contrast material) while X-rays are taken. This helps detect blockages and abnormal esophageal movement.

● Endoscopy: A thin, flexible tube with a camera is used to examine the inside of the esophagus and rule out other conditions like tumors.

While there’s no permanent cure for achalasia, several treatment options can help manage symptoms and improve swallowing. The goal is to relax or stretch the LES so food can pass into the stomach more easily.

● Pneumatic Dilation

This is a non-surgical procedure where a balloon is inserted into the LES and inflated to stretch the muscle. It can provide significant relief, though some patients may need repeat procedures.

● Medications

Medications like nitrates or calcium channel blockers can help relax the LES. These are often used for short-term symptom relief but may not be as effective as other treatments.

● Botulinum Toxin (Botox) Injections

Botox injections into the LES can temporarily relax the muscle, improving swallowing. However, the effects wear off after a few months, and repeat injections may be needed.

● Heller Myotomy

This is a surgical procedure where the muscles of the LES are cut to allow easier passage of food. It’s a highly effective treatment, often performed using minimally invasive techniques (laparoscopy).

● Peroral Endoscopic Myotomy (POEM)

POEM is a newer, minimally invasive procedure where an endoscope is used to cut the LES muscles from inside the esophagus. It has shown excellent results and is an alternative to surgery.

Your doctor will recommend a treatment based on your age, symptoms, and overall health.

In addition to medical treatments, some lifestyle adjustments can help manage achalasia symptoms:

● Eat Slowly and Chew Thoroughly: Taking small bites and chewing food well can make swallowing easier.

● Avoid Eating Before Bedtime: Lying down soon after eating can worsen regurgitation and night time coughing.

● Drink Water During Meals: Sipping water while eating may help move food into the stomach.

● Adjust Your Sleeping Position: Sleeping with your head elevated can reduce night time regurgitation.

If you experience persistent swallowing difficulties, unexplained weight loss, or frequent regurgitation, consult a healthcare provider promptly. Early intervention can help avoid complications and improve outcomes.
