Causes and Risk Factors for Achalasia (Cardiospasm)

Overview

Achalasia is a rare disorder that affects the esophagus (the tube that carries food from the mouth to the stomach), making it hard to swallow. It happens when the lower esophageal sphincter (LES), the ring-shaped muscle at the bottom of the esophagus, doesn’t relax properly, which prevents food and liquid from passing into the stomach. This causes food to back up in the esophagus, leading to symptoms like difficulty swallowing, chest pain, and regurgitation.

The exact cause of achalasia is not fully understood, but there are several theories about what might lead to the condition. Here are some key points to help explain the possible causes of achalasia:

  • One theory suggests that achalasia might be caused by the breakdown of a group of nerves called Auerbach's plexus, which helps control the movement of food through the esophagus.
  • Another theory suggests that damage to the nerves that control the throat, stomach, and other parts of the digestive system may contribute to causing achalasia.
  • The exact factors that damage these nerves and cause them to stop working are still unknown, but researchers believe genetics, autoimmune disease, and infections might play a role. While there are no clear patterns based on gender or race for who develops achalasia, it mostly affects adults between their 20s and 50s.
Risk Factors

The risk factors below increase the chances of developing achalasia. These include:

  • Age: Increasing age is a non-modifiable risk factor for achalasia. As people get older, their risk of developing achalasia increases.
  • Sex assigned at birth: Although the exact reason is not fully understood, studies have shown that being assigned male at birth may be a non-modifiable risk factor for achalasia. However, it is important to note that achalasia can affect people of all genders.
  • Genetics: Having a family history of achalasia can increase the risk of developing the condition. If someone has a close relative, such as a parent or sibling, who has been diagnosed with achalasia, their risk may be higher.
  • Race or ethnicity: While research on this topic is limited, there is some evidence to suggest that certain racial or ethnic groups may have a higher risk of developing achalasia. However, it is important to note that this does not mean other racial or ethnic groups are immune to the condition.
Reducing Risks

To prevent or reduce the chances of developing achalasia, there are several actions individuals can take to modify their risk factors. These actions include:

  • Maintaining a healthy weight: Being overweight or obese can increase the risk of developing achalasia. By maintaining a healthy weight through regular exercise and a balanced diet, individuals can reduce their risk.
  • Avoiding smoking: Smoking is a known risk factor for achalasia. Quitting smoking or avoiding exposure to second hand smoke can help lower the risk.
  • Managing stress: Chronic stress has been linked to various health conditions, including achalasia. Engaging in stress-reducing activities such as exercise, meditation, or hobbies can be beneficial.
  • Eating slowly and chewing food thoroughly: Eating too quickly or not chewing food properly can contribute to the development of achalasia. Taking the time to eat slowly and thoroughly chew food can help prevent this condition.
  • Avoiding trigger foods: Some individuals with achalasia may find certain foods worsen their symptoms. It's important to identify and avoid trigger foods that worsen symptoms.
  • Seeking treatment for acid reflux: Chronic acid reflux, also known as gastroesophageal reflux disease (GERD), is associated with an increased risk of achalasia. Managing GERD through lifestyle modifications and medications can help reduce the risk.
  • Discussing medication options with a doctor: Certain medications may increase the risk of developing achalasia. If you are taking any medications, it's important to discuss them with your doctor to assess their potential impact on your risk.

Remember, these actions are general recommendations and may not apply to everyone. It's always a good idea to consult with a healthcare professional for personalized advice and guidance on preventing or reducing the chances of developing achalasia based on your specific situation and medical history.
