Throat Bleeding and Abdominal Pain After Upper Endoscopy

Upper gastrointestinal endoscopy, throat bleeding, abdominal pain?

Hello Doctor: I underwent an upper gastrointestinal endoscopy (esophagogastroduodenoscopy) on the afternoon of September 12th (I fasted from 00:15 on September 12th until after the procedure, and I was able to eat again at 20:30).
The next morning, I noticed some injuries and bleeding in my oral cavity and throat (specifically on the pharyngeal wall visible from the oral cavity).
Although there is no significant pain, I have experienced abdominal pain since the procedure, which has shown signs of gradual improvement by this morning.
Is this normal? Under ideal healing conditions, how long does it typically take for these wounds to heal?

During gastroscopy, throat pain may occasionally occur, but generally, it resolves within a few days.
As for whether abdominal pain is related to the procedure, further evaluation is needed.

More Info

After undergoing an upper endoscopy (esophagogastroduodenoscopy, or EGD), it is not uncommon to experience some throat bleeding and abdominal pain. These symptoms can arise from the procedure itself, which involves the insertion of a flexible tube with a camera through the mouth and into the esophagus, stomach, and duodenum.

Understanding Throat Bleeding
Throat bleeding post-endoscopy can occur due to minor trauma to the mucosal lining of the throat or esophagus during the procedure. The endoscope can cause abrasions or small tears, especially if the patient has a sensitive throat or if the procedure was particularly challenging. While some bleeding may be expected, it should be minimal and typically resolves on its own.
In most cases, the throat and esophageal mucosa heal relatively quickly, often within a few days to a week. However, if the bleeding is significant, persistent, or accompanied by severe pain, difficulty swallowing, or other concerning symptoms, it is essential to seek medical attention.

Abdominal Pain After Endoscopy
Abdominal pain following an upper endoscopy can also be a common occurrence. This discomfort may result from several factors:
1. Air Insufflation: During the procedure, air is often introduced into the gastrointestinal tract to provide a clearer view. This can lead to distension and discomfort post-procedure.

2. Instrumentation: The manipulation of the endoscope can cause temporary irritation or trauma to the stomach lining, leading to pain.

3. Underlying Conditions: If there were pre-existing conditions such as gastritis or ulcers, the procedure might exacerbate these issues, resulting in pain.

Typically, this abdominal discomfort should gradually improve over a few days. If the pain worsens, becomes severe, or is accompanied by symptoms such as fever, vomiting, or significant changes in bowel habits, it is crucial to consult a healthcare provider.

Healing Time
In an ideal scenario, the healing of minor abrasions in the throat and esophagus can occur within a week. The mucosal lining is resilient and tends to regenerate quickly. However, individual healing times can vary based on factors such as overall health, age, and the presence of any underlying conditions.

Recommendations
1. Monitor Symptoms: Keep an eye on your symptoms. If the throat bleeding persists or worsens, or if you experience increasing abdominal pain, it is advisable to return to your healthcare provider for further evaluation.

2. Hydration and Diet: Stay hydrated and consider a soft diet to minimize irritation to the throat and stomach. Avoid spicy, acidic, or very hot foods that could exacerbate discomfort.

3. Follow-Up: If symptoms do not improve within a few days or if you have concerns about your recovery, do not hesitate to reach out to your healthcare provider for a follow-up appointment.

4. Rest: Allow your body time to recover. Avoid strenuous activities that could exacerbate abdominal discomfort.

In summary, while some throat bleeding and abdominal pain can be normal after an upper endoscopy, it is essential to monitor your symptoms closely. Healing typically occurs within a week, but if you experience any concerning symptoms, seeking medical advice is crucial for your health and peace of mind.
