What happens when lower esophageal sphincter pressure decreases?

Reduced lower esophageal sphincter pressure resulting in gastroesophageal reflux frequently coexists with impaired esophageal clearance of refluxed gastric contents due to diminished motility in the distal two thirds of the esophagus.

What is a hypotensive LES?

Hypotensive esophageal contractions are often associated with hypotensive LES. Hypotensive LES tone and weak distal esophageal contractions can lead to increased reflux and impaired esophageal acid clearance, respectively, thereby promoting the development of reflux esophagitis.

What are the symptoms of esophageal dysmotility?


  • Heartburn.
  • Regurgitation.
  • Chest pain.
  • Difficulty swallowing.
  • The feeling that food is stuck in the throat or chest.
  • Weight loss and malnutrition.
  • Recurrent bouts of pneumonia.

What is LES pressure?

Through rhythmic variations, the diaphragm influence lower esophageal sphincter (LES) pressure acting as an external sphincter. LES pressure recording is characterized by increased pressure in inspiration due to contraction of the diaphragmatic crura that involves the sphincter.

How can I improve my LES function?

Sleeping on your left side may help improve the flow of acid and other contents from the esophagus into the stomach. Eat smaller more frequent meals. Eat several smaller meals throughout the day rather than two or three large meals. Avoid eating high-calorie, high-fat meals in the evening.

How do I lower my LES pressure?

Limit high fat foods, e.g. fried foods, high fat baked goods, cream, ice cream, high fat cheeses, sausages, bacon, potato chips, etc. Fatty foods have been found to delay gastric emptying and decrease the LES pressure thereby prolonging the esophageal exposure time to stomach acid and the volume available for reflux.

What causes a loose LES?

Once the stomach is full, the LES closes to stop acid and bile from leaving the stomach. “In people with GERD, their LES is weak and either does not close completely or may open at inappropriate times,” says Dr. Purcell. “As a result, acid and bile can flow back up into the esophagus, especially while lying down.”

How do you diagnose LES?

Diagnosis and Tests The barium swallow will show a narrowing of the esophagus at the LES. Upper endoscopy: In this test, a flexible, narrow tube with a camera on it – called an endoscope – is passed down your esophagus. The camera projects images of the inside of your esophagus onto a screen for evaluation.

What causes the lower esophageal sphincter to fail?

Why your esophageal muscles fail to contract and relax normally is unknown. One theory is that achalasia is an autoimmune disease (your body attacks itself) that is triggered by a virus. Your immune system attacks the nerve cells in the muscle layers of the walls of your esophagus and at the LES.

What causes low LES pressure?

Decreases in LES pressure occurring after fat ingestion may explain a mechanism for many cases of fatty food intolerance. Pressure decreases after chocolate ingestion, after smoking, and after alcohol all have strong therapeutic implications in patients with chronic heartburn.

Why does LES weaken?

The fat in the stomach takes longer to be digested and moved into the intestines. This causes stagnation of food in the stomach. This increased pressure turns backwards and may weaken the LES.

How do you cure weak LES?

For the worst cases, surgeons may perform a laparoscopic procedure to tighten a weak L-E-S muscle. If you have occasional heartburn, antacid tablets can be used as needed. However! If you’re having heartburn more than 3 to 4 times a week, see your doctor & take the prescribed medication to prevent this condition.
