Colonoscopy Preparation And What You Need To Know

Proper preparation is essential for a successful colonoscopy. Before undergoing a colonoscopy, patients are generally advised to stop taking iron supplements three days prior to the procedure. Starting a few days before the exam, it's recommended to consume a low-residue or semi-liquid diet. Foods high in fiber, such as certain fruits and vegetables, should be avoided. Instead, opt for items like milk, rice porridge, noodles, fish, egg whites, and bread.

The day before your colonoscopy is crucial for bowel preparation. Patients typically begin taking laxatives the night before the exam and may continue in the morning with medications such as mannitol or polyethylene glycol (e.g., Suprep or similar). Drinking plenty of clear fluids helps flush the digestive tract, aiming for yellowish or clear liquid stools, which indicates that the bowels are adequately cleansed for the procedure.

In some cases, a light enema might be performed up to two hours before the exam to ensure optimal visibility during the procedure. During the colonoscopy, patients are usually positioned on their left side with knees drawn toward the chest. Keeping the abdominal muscles relaxed and following the medical team's instructions regarding position changes can help minimize discomfort. If significant pain occurs during the exam, it's important to communicate this to the doctor immediately.

Post-exam care is equally important. After the procedure, rest is recommended. Mild bloating or cramping is normal, but severe abdominal pain, persistent discomfort, or unusual symptoms should prompt immediate medical attention. It's also wise to have a family member or friend accompany you to the appointment, especially if sedation was used.

If you haven't eaten on the day of the exam and feel lightheaded or experience signs of low blood sugar, drinking a sugary beverage like simple syrup water can help restore energy levels. For the first 24 hours after the procedure, avoid driving, cycling, or engaging in high-altitude activities, particularly if you were sedated.

Following these guidelines improves both safety and diagnostic accuracy. Adhering to dietary restrictions, completing bowel prep as instructed, and allowing adequate recovery time afterward ensures the best possible outcomes from your colonoscopy. Always follow the specific instructions provided by your healthcare provider for optimal results.
