Why It Matters
Colonoscopy: What It Is and Why It Matters
A colonoscopy is a procedure in which a gastroenterologist uses a flexible camera (colonoscope) to examine the inside of your large intestine (colon). This allows us to detect and remove polyps, identify inflammation or tumors, and catch early signs of colorectal cancer.
Why does that matter? Early detection saves lives. Colon cancer usually starts as small polyps; if we find them early during a colonoscopy, we can remove them on the spot, preventing them from turning into cancer. The American Cancer Society now recommends starting routine colonoscopy screenings at age 45 (earlier if you have risk factors like family history). In fact, colonoscopy can reduce the risk of colon cancer by detecting precancerous growths before they cause problems. It's a safe, routine outpatient procedure and it can be truly life-saving.
We emphasize this to encourage our patients not to put off their colonoscopy. After all, a one-day prep and exam every 10 years is a small investment in your long-term health and peace of mind.
Patient Safety
Your safety is our top priority. Colonoscopies are performed under sedation in our AAAASF-accredited endoscopy suite, with an anesthesiology professional monitoring you throughout the procedure. We proudly serve patients from Forest Hills, Rego Park, Kew Gardens, Elmhurst, Jackson Heights, and all of Queens.
Timing
When Should I Have a Colonoscopy?
Use the situations below to gauge timing. Always confirm with your gastroenterologist.
When should I schedule a screening colonoscopy if I have no symptoms and no family history?
At age 45. Multiple professional society guidelines recommend routine screening colonoscopy starting at 45 for average-risk adults.
Schedule your screeningWhen should I start colonoscopies if a parent or sibling had colon cancer?
At age 40, OR 10 years before your relative was diagnosed, whichever comes first. Less common high-risk criteria should be discussed with your gastroenterologist.
Discuss your family history with usI have rectal bleeding or a recent change in bowel habits. Should I wait for screening age?
No. Rectal bleeding, unexplained weight loss, or new-onset constipation or diarrhea are red flags for a diagnostic colonoscopy now, regardless of age.
Call us at (718) 261-0900When should I repeat my colonoscopy if my last one was clean?
Typically 10 years if you are average-risk and no polyps were found. Your gastroenterologist sets the exact interval based on your individual history.
When should I have my next colonoscopy if polyps were removed?
Usually 3 to 5 years, depending on polyp type, size, and count. Your gastroenterologist sets the interval based on pathology results from your last procedure.
I am hesitant about the procedure. How do you make the colonoscopy comfortable?
We walk every patient through the prep and procedure step by step. Propofol sedation means you feel nothing, and our AAAASF-accredited suite focuses on safety and comfort.

Why Patients Choose Us
Why Choose Us for Your Colonoscopy?
Choosing a provider for your colonoscopy is important. Here's why patients in Forest Hills and across Queens trust us:
Experienced, Compassionate Specialists
Our colonoscopies are performed by Dr. Samuel Davidoff and our team of board-certified gastroenterologists. We have decades of combined experience and have successfully performed thousands of procedures, yet we treat every patient with individualized care and attention. You're never just a number to us.
Comfort-Focused Care
Your comfort and safety are our top priorities. We use modern sedation techniques (administered by anesthesiology professionals) so you'll be comfortably asleep during the exam and won't feel any pain. Nervous about the idea of a colonoscopy?
State-of-the-Art Facility
Our office features an AAAASF-accredited on-site endoscopy suite. This means you can have your colonoscopy right in our Forest Hills office, conveniently located for patients from Rego Park, Kew Gardens, Elmhurst, Jackson Heights, and across Queens, which meets the highest safety standards (the same as a hospital). Our equipment is modern, and we even use high-definition scopes and the latest polyp detection techniques to make sure nothing is missed.
Convenience & Personal Attention
Being a private practice, we offer prompt scheduling including early morning appointments on weekdays and even Sunday morning slots to fit your busy life. Unlike a big hospital or clinic, you'll consult directly with your GI doctor before and after the colonoscopy. We'll personally call you with results and next steps. Patients from Rego Park, Kew Gardens, Elmhurst, Jackson Heights, and throughout Queens choose us for this personalized experience. Continuity of care is a hallmark of our practice.
Comprehensive Digestive Health Approach
As our name suggests, we look at the whole picture of gastroenterology and nutrition. If your colonoscopy reveals any issues (like ulcerative colitis or polyps), we'll not only treat them but also counsel you on diet and preventive care going forward. Our aim is to keep your digestive system healthy for the long run, not just perform a one-time test.

The Colonoscopy Procedure
A colonoscopy is generally performed as an outpatient procedure. The patient is positioned on the left side and a sedative is administered intravenously.
Day-Of Walkthrough
What to Expect During Your Colonoscopy
Many patients are surprised how quick and simple the actual colonoscopy is compared to the prep. Here's an overview of what will happen on the day of your colonoscopy at our Forest Hills endoscopy suite
1
Before the Procedure
After check-in, you'll meet with our nursing team to review your medical history and allergies. You'll sign a consent form (if you haven't already) and change into a gown. We'll start an IV line, through which you'll receive fluids and later, sedative medication. You'll also meet your anesthesiologist or nurse anesthetist, who'll be monitoring you. In the procedure room, we'll have you lie on your left side on a comfortable stretcher. We attach small monitors for your blood pressure, heart rate, and oxygen. Safety is always paramount. Then we administer the sedation medication through the IV, which will make you drift off to sleep within a minute or two.
2
During the Colonoscopy
Once you're sedated, the gastroenterologist will gently insert the lubricated colonoscope into the rectum and slowly advance it through the colon. The scope is a thin, flexible tube with a tiny camera and light at the end. As we carefully navigate through your colon's curves, we may put a small amount of air (or carbon dioxide) inside to inflate the colon slightly. This gives us a better view of the colon walls. Don't worry, you won't feel this due to sedation (at most, some patients have mild cramping or pressure that they don't recall later). The camera sends high-definition video to a screen, allowing us to examine every segment of your colon. If we spot any polyps or abnormal tissue, we use miniature instruments passed through the scope to remove them or take biopsies. Polyp removal (polypectomy) is painless and done during the same session. Polyps are cut off using a wire loop or burned off safely, and the tissue is collected for lab analysis. The procedure usually takes about 20 to 30 minutes (it can be a bit longer if multiple polyps are found and removed, or shorter if everything looks normal). Throughout the exam, your vital signs are monitored continuously. Our team will adjust your position gently if needed (sometimes we reposition you to help the scope pass a tricky angle).
3
After the Procedure
When the colonoscopy is finished, the scope is slowly withdrawn and the exam is complete. We escort you to a recovery area, where you'll rest as the sedative wears off. Most patients wake up within 5 to 10 minutes after the procedure ends, but can be groggy for about half an hour. You might not even realize the colonoscopy happened. Many people say, “Are we done already?” because the sedation has an amnesia effect. We like to see a smile on your face when you hear it's all done! In the recovery area, you may feel bloating or cramping; this is normal and simply due to the air introduced into the colon. We encourage you to pass gas, yes, farting is expected! to help relieve the bloating. Nurses will monitor your blood pressure and make sure you're feeling okay. We'll also offer you something to drink as you wake up (your throat and mouth might be dry). Once you're fully awake and our doctor has spoken with you about initial findings, you'll be discharged to go home with your companion. From check-in to check-out, expect to spend around 2 to 3 hours at our facility.

Colon Polyp Removal During Colonoscopy
If polyps are found during your colonoscopy, Dr. Davidoff can typically remove them during the same procedure, a technique called polypectomy. Most polyps are removed painlessly in seconds using a small snare or forceps passed through the scope. Removed tissue is sent for pathology review, and results are shared with you at your follow-up. Catching and removing polyps before they develop into colon cancer is the core reason screening colonoscopy saves lives.
After the Procedure
Recovery from a Colonoscopy
Recovering from a colonoscopy is usually quick. There's no incision (everything is internal), so physical recovery mainly involves shaking off the sedation effects. Here's what to do and expect after you leave
Heading Home
You must not drive or return to work the same day because of the sedation. Go home and rest. Plan to take the remainder of the day off. Most people feel back to normal by the next morning. You might feel a bit drowsy or unsteady on your feet for a few hours, this is normal. Take it easy and let your body relax. Have a light meal when you feel up to it; start with something gentle on the stomach. You've been on clear liquids, so you may be hungry but it's wise to avoid a heavy, greasy meal as your first meal post-colonoscopy. Resume your normal diet as tolerated.
Side Effects
It's common to experience bloating or gas cramps for a few hours due to any remaining air in the colon. This should resolve by the evening. You might also notice a small amount of blood in your first bowel movement post-colonoscopy if a biopsy or polyp removal was done. A few drops on the toilet paper or a slight tinge in the stool is okay. However, call us if you have heavy rectal bleeding (more than a few tablespoons), severe abdominal pain, fever, or dizziness. These symptoms are very rare (<0.5% of cases) but we want to hear from you immediately if they occur. Our staff will provide you with a simple info sheet listing these signs to watch for, though significant complications are rare. Overall, colonoscopy is considered a very safe procedure.
Results Discussion
Before you go home, Dr. Davidoff (or your GI doctor) will let you know how things looked internally. We will tell you if we found polyps and whether we removed them, or if everything looked healthy. We send any removed polyps or biopsy samples to a pathology lab, those results take about 5-7 days to come back. We will call you with your pathology results as soon as they're available, and of course, we'll explain what they mean and if any follow-up is needed. If everything is normal and you have no risk factors, the standard interval for the next colonoscopy is 10 years. If we removed polyps or found something that needs sooner surveillance, we'll let you know the appropriate follow-up interval (e.g., 3 or 5 years).
Resuming Activities
Most patients are fully back to routine by the next day. That means you can return to work, exercise, and normal activities within 24 hours. The sedative medications are mostly out of your system after a good night's sleep. We do advise no alcohol, driving, or signing important documents for at least 24 hours post-procedure, since sedation can linger in subtle ways. Otherwise, focus on rehydrating (drink plenty of fluids to make up for the day before) and eating healthy meals. If we gave you specific post-care instructions (for example, if a large polyp was removed, sometimes we suggest avoiding aspirin/NSAIDs for a day or two), be sure to follow those. We're always here to answer questions even after the procedure, don't hesitate to call our office if you're unsure about anything during your recovery.
FAQ
Common Questions About Colonoscopy
We understand you may have concerns about your procedure. Here are answers to questions our Forest Hills patients frequently ask.
According to multiple professional society guidelines, the average patient without symptoms should start doing screening colonoscopies at age 45. Patients who are at an increased risk of colon cancer, those who have a first or second degree relative with colon cancer, should start doing screening colonoscopies at age 40 or 10 years prior to the age at which that relative was diagnosed, whichever comes first. There are other less common high-risk criteria, which should be discussed with your gastroenterologist.
Rectal bleeding, unintentional weight loss, new-onset unprovoked constipation or diarrhea, or any change in bowel habit.
The patient comes into the office, fills out some paperwork and goes to the changing room, where they change into a gown. We then bring the patient into the procedure room, where they lay down on the bed and the anesthesiologist inserts an IV that will be used to put them to sleep. We then ask the patient to lay on their left side. The anesthesiologist injects the sedative. After the patient is fully asleep we insert a flexible tube with a camera (the colonoscope) into the anus and pass it through the whole colon. Once we reach the “end” of the colon (the cecum) we start to slowly withdraw the colonoscope looking for polyps (growths that can turn into cancer); if we find a polyp, we remove it right there and then. When the procedure is over, the patient wakes up and is ready to go home within 30 minutes. The procedure itself takes an average of about 20 to 30 minutes.
We are an AAAASF certified facility using state of the art equipment. Our gastroenterologists, anesthesiologists, and medical assistants have a tremendous amount of experience in doing colonoscopies as well as endoscopies. Patient safety and comfort are our top priority.
Yes, the bowel prep is available in pill form. It is called Sutab.
You can make an appointment for a consultation usually the same week that you call us and we can schedule you for a colonoscopy soon thereafter.
Yes, we do endoscopies and colonoscopies on Sunday.
We accept the majority of commercial insurances, Medicare and the various types of Medicaids. Please contact us directly at 718-261-0900 for more details.
Colonoscopy cost depends on your insurance plan, the type of colonoscopy (screening or diagnostic), and whether polyps are removed. Under the Affordable Care Act, most commercial insurance plans cover screening colonoscopy at age 45 or older as a preventive benefit when performed in-network. Medicare covers screening colonoscopy at the same age. Actual cost share depends on your specific plan, deductible, and whether polyps are found and removed during the procedure (which can reclassify the procedure from screening to diagnostic). Our team verifies your benefits before the appointment and provides a personalized estimate for any expected out-of-pocket costs. Call 718-261-0900 for a coverage check.
At our AAAASF-accredited Forest Hills endoscopy suite, colonoscopies are performed under monitored sedation with an anesthesiology professional present throughout. The two most common options are monitored anesthesia care (MAC) with propofol for a deeper sleep and no memory of the procedure, and moderate conscious sedation for a lighter experience and quicker recovery. Dr. Davidoff discusses the best option for you during your pre-procedure consultation based on your health history and preferences.

Sí. Cuando es médicamente apropiado, nuestros gastroenterólogos pueden realizar una endoscopia superior (también llamada gastroscopia o EGD) y una colonoscopia durante la misma visita, usando una sola sedación. Combinar las dos pruebas significa una sola preparación, una sola sedación, y un solo día de recuperación. Su gastroenterólogo decidirá si combinar ambos procedimientos es lo correcto para usted según sus síntomas y antecedentes médicos.
El procedimiento en sí dura aproximadamente entre 30 y 45 minutos en total (la endoscopia superior toma de 5 a 15 minutos y la colonoscopia toma de 20 a 30 minutos). Planee pasar entre 2 y 3 horas en nuestra oficina, incluyendo el registro, la preparación con sedación, los procedimientos, y la recuperación. Necesitará que alguien lo lleve a casa después debido a la sedación. La mayoría de los pacientes regresa a sus actividades normales al día siguiente.
No. Usted hará la misma preparación de colonoscopia que haría si solo se realizara una colonoscopia, más un período de ayuno más largo para la endoscopia superior. Nuestro equipo le dará un solo conjunto de instrucciones que cubre ambos procedimientos. No necesita seguir dos protocolos de preparación separados.
Sí. Para la mayoría de las hemorroides internas, podemos realizar tratamientos como la ligadura con banda elástica, la coagulación infrarroja, o la escleroterapia durante su colonoscopia, sin necesidad de una sedación adicional ni una cita aparte. Las hemorroides externas y las hemorroides internas severas (Grado IV) generalmente requieren una evaluación separada. Mencione sus síntomas de hemorroides cuando llame para programar su colonoscopia para que podamos planificar la cita en consecuencia.
