Understanding Colonoscopy Preparation
A colonoscopy is a common screening procedure used to examine the lining of the large intestine (colon and rectum) for any abnormalities. It involves inserting a tiny camera on the end of a flexible tube into the anus to view the rectum and entire colon. For the gastroenterologist to get clear images and thoroughly examine the colon, it is vital that the bowel be completely emptied and cleaned before a colonoscopy.
The Importance of Colon Cleansing
Thorough cleansing helps get rid of all solid matter from the bowels. This ensures maximum visibility and enables the doctor to detect even small polyps or lesions for biopsy if necessary. That is why patients need to follow a strict colonoscopy prep diet for a few days leading up to the procedure. This preparation is necessary for a successful colonoscopy.
The colon prep causes diarrhea, which clears the bowel well. Newer preparations make the cleansing process relatively tolerable and more convenient than older preps.
Makeup Can Interfere with the Procedure
Since the colonoscope camera needs to get very close to the lining of the colon to capture images, any residual matter could obscure lesions or growths. This means all contents including stool, mucus, flakes of skin, germs etc. must be washed out.
Makeup products contain various chemicals, mineral oils, fillers, color pigments, and other ingredients that could contaminate the colon. Just a little makeup left inside the rectum or colon can obstruct vision. Eyeliner, mascara, lipstick, foundation and face makeup often contain materials that do not get digested or dissolved.
Waterproof Makeup is Especially Problematic
Waterproof cosmetics and long-lasting makeup are formulated not to smudge, streak or wash off easily. The polymers and special pigments cling tenaciously to the skin. While these properties keep them intact for hours despite exposure to oil, sweat, tears or moisture, they can linger inside the colon too.
The residue can potentially adhere to the wall or polyps and be difficult to wash off completely. Dermatologists recommend makeup remover wipes and cleansing oils to break down waterproof makeup effectively. No such dissolving agents can be introduced into the colon during the scoping procedure.
How Makeup Can Impact Colonoscopy Results
Any traces of makeup in the rectum or colon can have adverse effects on the accuracy of your colonoscopy results in the following ways:
1. Obscure abnormalities
The camera needs full visibility to capture clear and detailed images of the entire colon lining. Mascara particles, foundation, glitter crystals from eye shadow or any makeup residue floating in the colon can obstruct complete visualization. They could cling to delicate tissue surfaces and hide flat lesions, small growths or polyps.
2. Mimic suspicious lesions
Certain makeup compounds may coat the wall tissue and potentially resemble polyp lesions. For example, chunks of waterproof lipstick or eyeliner flakes could cling to folds in the colon lining. When examined through the colonoscope, these may display textural, color or structural characteristics suggestive of abnormal tissue growths. The gastroenterologist may then take unnecessary biopsy samples from healthy areas.
3. Cause equipment contamination
If makeup debris enters the inner channels or equipment tip, it could interfere with image transmission and light projection used for scoping. Delicate optics and electronics enabling the HD video colonoscopy could get contaminated by oily chemicals, pigments and dyes. This can negatively impact the examination and require additional disinfection procedures.
4. Increase infection risk
While rare, a colonoscopy does involve a slight risk of introducing infection or microbes into the bowel. Any germs on makeup brushes used near eyes or lips could potentially transfer inside via the lubricated scope. Makeup left on skin near the anus may also contamination the equipment tip. The residue can harbor bacteria that enter the colon, heighten infection risk after biopsy or polyp removal.
How to Prepare for a Colonoscopy without Makeup
Proper cleansing is vital before a colonoscopy so follow prep guidelines carefully for best results. Here are some makeup-related tips to help:
When scheduling your appointment
Schedule a morning procedure to use the night before for cleansing, avoiding makeup altogether that day. Also, ask if a dressing gown and hygiene kit are provided so you needn't carry personal toiletries.
A week before the colonoscopy
Discontinue using glittery eye makeup, waterproof mascara and long-wearing lip colors that are hard to remove. Stick to regular or organic makeup products that clean off more easily and completely. Stock up on makeup remover wipes suitable for sensitive skin.
A day before the examination
Use a gentle makeup remover cleanser followed by wipes to carefully remove every trace of makeup. Pay attention to areas around the eyes, lips, brows and nose. Use soft cotton pads soaked in micellar water or oil-based remover to gently wipe off any stubborn makeup residue.
Morning of the colonoscopy
Use a mild sulfate-free washcloth and water to wash your face. Avoid reapplying any makeup, lotions or sunscreens. Follow all pre-procedure instructions from your doctor. For toilet visits right before leaving home, remember to only use water and toilet paper.
Does a Colonoscopy Really Require Going Makeup-Free?
While skipping makeup may seem inconvenient, going without it is necessary when undergoing an internal examination like a colonoscopy. Traces of cosmetics inside the rectum or colon can impact accuracy of results.
The medical team needs a clear field of vision inside the lower bowel to detect any abnormalities. Cleansing properly by avoiding all makeup and following prep guidelines ensures an effective colonoscopy.
Remember, catching colon cancer early or finding and removing precancerous polyps leads to highly successful treatment. So a thorough, high-quality colonoscopy is well worth the small inconvenience of skipping makeup application temporarily!
