An endoscopy is a common medical procedure where a flexible tube with a camera, called an endoscope, is inserted through the mouth to examine the upper digestive system (esophagus, stomach, and duodenum). While generally safe, a sore throat is a common and temporary side effect of the procedure.
Causes of Throat Soreness
Throat soreness after an endoscopy primarily stems from the physical passage of the endoscope itself, which can mildly irritate or traumatize the sensitive tissues of the pharynx and esophagus. Air is also gently pumped through the endoscope to inflate the digestive tract for clear visualization. This air can contribute to a sensation of fullness or soreness in the throat.
The body’s natural gag reflex can also contribute to discomfort. Even with sedation, the endoscope’s insertion may trigger this reflex, causing muscle strain. Anesthesia or sedation can also leave the throat feeling dry or irritated as their effects wear off.
Duration of Discomfort
A sore throat after an endoscopy is typically short-lived, with discomfort subsiding within 24 to 48 hours. While some mild irritation may linger slightly longer, this temporary response is normal. It is not a cause for concern if the pain is mild and gradually improves.
Relief for a Sore Throat
Several simple, at-home remedies can help manage throat discomfort after an endoscopy. Sipping on cool liquids, such as water or herbal teas, can provide soothing relief and help keep the throat moist. Gargling with warm salt water is another effective method, as the salt can help reduce inflammation and promote healing. Consuming soft foods like yogurt, mashed potatoes, or soup is advisable, as these are less likely to irritate the throat compared to harder or rougher textures.
It is also beneficial to avoid irritants such as very hot or spicy foods, as well as acidic beverages, during the initial recovery period. Over-the-counter pain relievers, such as acetaminophen or ibuprofen, can be taken to alleviate soreness, provided there are no contraindications and they are used according to dosage instructions. Sucking on throat lozenges or using throat sprays containing ingredients like menthol or honey can also offer temporary relief.
When to Contact Your Doctor
While a sore throat is a common side effect, certain symptoms after an endoscopy are not typical and warrant immediate medical attention. Contact your healthcare provider if you experience:
- Severe or worsening throat pain that does not improve
- Difficulty swallowing liquids or solids
- Chest pain or trouble breathing
- Fever or chills
- Persistent nausea or vomiting
- Any signs of bleeding, such as bloody or very dark stools
These symptoms could indicate a complication requiring prompt evaluation and communication with your medical team.
