What Does LA Grade B Esophagitis Mean on My Endoscopy?

If your endoscopy report says “LA Grade B esophagitis,” it means the doctor saw visible breaks in the delicate tissue lining your esophagus. While these breaks are most commonly caused by stomach acid washing up into the esophagus (acid reflux), the LA grade itself simply describes the size and extent of the tissue breaks, not the underlying cause or the exact severity of your symptoms ^[1].

Grade B is a highly treatable finding that usually heals well with standard acid-suppressing medications ^[2]. However, it is clinically significant: under updated medical guidelines, it provides conclusive objective evidence that you have true Gastroesophageal Reflux Disease (GERD) ^[3].

The Los Angeles (LA) Classification System Explained

Gastroenterologists use the Los Angeles (LA) Classification system to grade the severity of mucosal breaks—areas where the esophageal lining has worn away, commonly due to erosive esophagitis ^[4]. The system grades the visible extent of the injury from A (mildest) to D (most severe) ^[4]:

• Grade A: One or more mucosal breaks that are 5 millimeters or smaller and do not stretch between the natural folds of the esophagus ^[4][5].
• Grade B: At least one mucosal break larger than 5 millimeters, but the breaks still do not connect across the natural folds of the esophagus ^[4][5].
• Grade C: Mucosal breaks that stretch across multiple esophageal folds, but cover less than 75% of the esophagus circumference ^[4][5].
• Grade D: Mucosal breaks that involve 75% or more of the esophageal circumference ^[4][5].

It is important to note that your LA grade does not always match how you feel. A person can have Grade B visible breaks with very few symptoms, while someone else might experience severe heartburn with no visible breaks at all ^[6].

What Grade B Means for Your Diagnosis

While Grades A and B describe less extensive tissue breaks than C and D, Grade B carries important diagnostic weight ^[7]. Under the Lyon Consensus 2.0 guidelines, having LA Grade B esophagitis is considered objective, conclusive evidence of GERD ^[3][8].

In many straightforward cases, this means your doctor does not need to order invasive pH testing to prove you have acid reflux ^[8]. However, this is not an absolute rule. If your symptoms are atypical, if they do not improve with treatment, or if you are considering anti-reflux surgery, your doctor may still recommend further reflux monitoring to ensure acid reflux is the true root cause of all your symptoms ^[3].

Healing and Treatment Steps

Grade B esophagitis is highly treatable. In most cases, these mucosal breaks heal successfully when treated with a proton pump inhibitor (PPI), a medication that strongly reduces stomach acid ^[2][9].

Typically, healing is attempted with a once-daily PPI taken before a meal for about eight weeks ^[10]. Do not stop taking your prescribed medication abruptly without speaking to your doctor. Once the initial healing period is complete, your doctor will discuss a long-term maintenance plan. Because erosions and symptoms can recur when treatment stops, your doctor will help you find the lowest effective dose ^[11]. Depending on your unique situation, complications, and preferences, this might mean continuing a daily pill, reducing the dose, or eventually taking it only “on-demand” ^[11][12].

When is Another Endoscopy Needed?

Grades C and D are severe forms of erosive esophagitis that warrant active, aggressive treatment ^[13]. For those severe grades, doctors typically require a follow-up endoscopy after treatment to confirm healing and to check for conditions like Barrett’s esophagus that may have been hidden by the extensive tissue inflammation ^[10][14].

For Grade B, a routine follow-up endoscopy is often not required if your symptoms completely resolve with medication ^[12]. However, your doctor may recommend a repeat endoscopy if your symptoms persist, if dysphagia (difficulty swallowing) remains, or if they suspect other issues like Barrett’s esophagus ^[12][14].

When to Seek Prompt Medical Attention

While Grade B esophagitis is manageable, inadequate treatment can permit complications like bleeding or stenosis (narrowing) over time ^[15]. You should contact your doctor promptly or seek urgent care if you experience “alarm symptoms” that could indicate complications or a different condition entirely ^[15]:

• Difficulty swallowing or pain when swallowing
• Food feeling stuck in your chest or throat
• Vomiting blood or material that looks like coffee grounds
• Black, tarry stools (a sign of bleeding)
• Unexplained weight loss or anemia (low iron)
• Persistent, severe chest pain (always seek emergency care for concerning chest pain)

Terms to Know

• Mucosal break: An area where the surface layer of the esophagus has worn away or eroded ^[4].
• Hiatal hernia: A condition where the top part of your stomach pushes up through your diaphragm into your chest cavity, which can worsen reflux symptoms ^[12].
• Barrett’s esophagus: A condition diagnosed by taking biopsies (tissue samples) during an endoscopy, where the normal tissue lining the esophagus changes, slightly increasing the risk of esophageal cancer ^[14].
