A capsule endoscopy is a non-invasive medical procedure utilized to visualize the small intestine, an area not easily reached by traditional endoscopy methods. This diagnostic tool involves swallowing a small capsule equipped with a camera. Many individuals express apprehension about swallowing the capsule due to its size, but the process is generally well-tolerated. Understanding its components and the process can help alleviate concerns.
Understanding the Capsule
The capsule is specifically designed for ingestion and passage through the digestive system. It is comparable in size to a large vitamin pill, typically measuring around 11 mm by 26 mm. Its smooth outer coating helps facilitate movement, minimizing discomfort during swallowing. The capsule’s construction ensures easy passage once ingested.
The Swallowing Process
Swallowing the capsule is similar to taking a large vitamin. Patients typically swallow it with a generous amount of water.
Healthcare professionals often provide specific instructions, such as moistening the mouth with sips of water first or tilting the head forward slightly to help position the capsule. Some individuals find that taking a large gulp of water with the capsule helps it go down smoothly.
While a momentary sensation of a lump in the throat may occur, the capsule rarely gets stuck or causes pain during this initial phase. For most patients, the swallowing process is quick and straightforward, often taking only a few seconds.
Preparing for a Smooth Swallowing Experience
Preparation is important for a successful and comfortable capsule endoscopy. Patients are typically advised to follow specific fasting guidelines before the procedure, such as refraining from eating or drinking for 10 to 12 hours prior. This ensures the stomach is empty for clear imaging and easier swallowing. Following a clear liquid diet the day before the procedure, as instructed by medical staff, also helps prepare the digestive tract. Patients are encouraged to remain calm and follow the guidance provided by the nursing staff, who are experienced in assisting with the swallowing of the capsule.
What Happens After the Capsule is Swallowed?
After swallowing the capsule, patients can leave the clinic and resume light daily activities. The capsule travels through the digestive tract, propelled by the body’s movements. Its tiny camera captures images of the intestinal lining, transmitting them wirelessly to a data recorder worn by the patient. The single-use capsule passes naturally out of the body with a bowel movement, usually within 24 to 72 hours, and does not require retrieval.
