👀 Ever wonder what the scope actually looks like that’s used during your colonoscopy?

Dr. Nathanson gives you a closer look at the colonoscope, including just how thin and flexible it actually is!

And here’s the part patients love: before the procedure, you can get comfortable, pick out some music, and then it’s time for a little nap. 😴

Before you know it, you’re awake, the procedure is over, and you’ve got a snack waiting for you. 🍪🧃

Colonoscopy might not be at the top of anyone’s bucket list, but knowing what to expect can make the experience feel a whole lot less intimidating.

Colonoscopy prep doesn’t have to be as intimidating as you’ve heard! 👏

Dr.Nathanson is sharing a few simple tips that can make prep day a little easier:

🥶 Chill your prep—it often tastes better when it’s cold.

🥤 Drink it through a straw to help reduce the taste.

🫖 “Clear liquids” don’t have to be colorless! If you can see through it (think tea, lemonade, broth, or black coffee), it’s usually fair game. Just be sure to follow the specific instructions provided.

🍬 Need something to chew? Jell-O and even gummy bears (avoiding red, purple, and other colors your prep instructions tell you to avoid) can help make your clear liquid day a little more manageable.

✨ Dietitian Spotlight: Julie ✨

Meet Julie, one of our Registered Dietitians!
💙 Fun fact: Julie made a midlife career change and followed her passion into nutrition. Throughout her 20s and 30s she worked in advertising before deciding to go back to school, earn her master’s degree, and pursue the career she truly loved—and we’re so glad she did!

💬 We asked: “What’s an underrated gut-healthy food?”

Her answer: Basil seeds! 🌱

Julie describes basil seeds as similar to chia seeds—but with even more fiber, plus calcium and protein. They can be an easy way to add a little extra nutrition and support digestive health.

One of our favorite events of the year! 💙💚

Our team was honored to participate in the Crohn’s & Colitis Foundation’s Take Steps walk, celebrating the strength and resilience of the IBD community. Shout out to our very own Dr. Brett Riederman for delivering a fantastic speech on behalf of everyone here at CGH as the 2026 Honored Healthcare Heroes.

Every step represents hope—for better treatments, continued research, and improved quality of life for those living with Crohn’s disease and ulcerative colitis.

Thank you to our patients, families, friends, and colleagues who joined us. We are grateful to be part of such an inspiring community.

Swipe to the end to see one of our fave docs finish his run! 😄

Last year’s Take Steps walk was such a meaningful day for our team, and we’re excited to be back again this Sunday, June 14! 💙

This year is especially meaningful for us as CGH has been selected as the Honored Healthcare Heroes for the 2026 North Shore campaign with the Crohn’s & Colitis Foundation—something that reflects our continued commitment to supporting our IBD community both inside and outside the clinic.
We’re also incredibly grateful for the support that has helped our team raise over $15,000 so far.

If you’re free this weekend, we’d love to have you join us at Gallery Park East in Glenview for this family-friendly event alongside our team and community. Ribbon ceremony will be at 11:45am with the 1.5 mile walk immediately to follow.
