As individuals age, the risk of developing colorectal cancer increases. This makes colonoscopy, a procedure used to examine the colon and rectum, an essential tool for early detection and prevention of this potentially life-threatening disease.

If you are over the age of 75 or caring for someone in this age group, understanding what to expect from a colonoscopy after 75 is crucial. This article aims to provide you with a comprehensive guide to help you navigate the process with confidence and ease.

Why is Colonoscopy Important After 75?

Colonoscopy is an important screening test for individuals aged 75 and above because the risk of developing colorectal cancer increases significantly in this age group.

According to the American Cancer Society, more than 90% of colorectal cancer cases occur in individuals aged 50 or older, making regular screenings vital for early detection and treatment.

By undergoing a colonoscopy after 75, you can:.

1. Detect Colorectal Cancer Early

Colorectal cancer often begins as small growths called polyps, which can be noncancerous or premalignant.

During a colonoscopy, the gastroenterologist can identify and remove these polyps before they have a chance to become cancerous, effectively preventing the disease altogether or catching it at an early stage when it is highly treatable.

2. Prevent Colon Cancer

A colonoscopy not only helps in detecting colorectal cancer but also serves as a preventive measure. Removing polyps during the procedure reduces the risk of these polyps developing into cancer.

This is particularly crucial for individuals aged 75 and above, as the likelihood of polyps and cancerous growths increases with age.

3. Assess the Health of the Colon

Besides checking for colorectal cancer, a colonoscopy provides valuable information about the overall health of the colon.

The procedure allows the gastroenterologist to evaluate the colon’s condition, identify any inflammation, ulcers, or abnormalities, and address them promptly. This not only aids in the early detection of potential diseases but also helps manage existing conditions such as inflammatory bowel disease (IBD) and diverticulosis.

4. Set a Baseline for Future Screenings

If you have never undergone a colonoscopy before, turning 75 is an ideal time to start. This initial screening will set a baseline for future screenings, allowing your healthcare provider to compare and monitor any changes in your colon over time.

Regular screenings are crucial in maintaining good colon health and detecting any early signs of cancer or other diseases.

What Happens Before a Colonoscopy?

Before a colonoscopy, there are several steps and preparations to follow. These typically include:.

1. Consultation with a Gastroenterologist

Schedule an appointment with a gastroenterologist who specializes in colonoscopies. They will assess your medical history and any current health concerns, review medications you are taking, and address any questions or concerns you may have.

2. Preparatory Instructions

Your gastroenterologist will provide specific instructions on how to prepare your colon for the procedure.

This usually involves dietary changes, such as consuming a clear liquid diet the day before the colonoscopy, and taking laxatives or prescribed bowel preparation medication to cleanse your colon thoroughly.

3. Medication Adjustments

Inform your gastroenterologist about any medications you regularly take, as some may interfere with the colonoscopy or its preparation process. They will advise you on whether to temporarily adjust or discontinue any medications.

4. Transportation Arrangements

As sedation is commonly used during a colonoscopy, it is crucial to arrange for transportation to and from the procedure, as you may feel groggy or drowsy afterward.

It is best to ask a family member or friend to accompany you or, if necessary, arrange for a taxi or ride-sharing service.

What Happens During a Colonoscopy?

During a colonoscopy, a gastroenterologist carefully examines the entire length of the colon using a colonoscope. Here is a general overview of what typically occurs during the procedure:.

1. Anesthesia Administration

Prior to the procedure, you will likely be administered anesthesia to keep you comfortable and relaxed throughout the colonoscopy. The type of anesthesia used can vary, and your healthcare provider will discuss the options with you.

2. Insertion of the Colonoscope

Once you are sedated, the gastroenterologist inserts a colonoscope, a flexible and thin tube with a light and camera attachment, into your rectum and slowly advances it through the colon.

This allows for a detailed and real-time visualization of the colon’s interior.

3. Examination and Polyp Removal

As the colonoscope is advanced, the gastroenterologist closely examines the colon’s walls, looking for any abnormalities, polyps, or signs of inflammation.

If polyps are discovered, they are typically removed using specialized tools or techniques to prevent them from developing into cancerous growths.

4. Biopsy (if necessary)

If any suspicious areas or abnormal tissue are identified, the gastroenterologist may perform a biopsy. This involves taking a small sample of tissue for further analysis. The results can help determine the presence of cancer or other diseases.

What Happens After a Colonoscopy?

After the colonoscopy, you will be moved to a recovery area where the effects of the anesthesia will wear off under observation. Here is what you can expect post-procedure:.

1. Recovery Time

The recovery time after a colonoscopy is usually brief. However, the duration may vary depending on factors such as your overall health, the type of anesthesia used, and the presence of any complications during the procedure.

2. Residual Air and Discomfort

It is common to experience some residual air in the colon, which may cause mild bloating or gas. This discomfort typically subsides within a few hours as the gas is naturally expelled from the body.

3. Fatigue and Drowsiness

The sedation administered during the colonoscopy can leave you feeling tired or drowsy for a few hours. It is advisable to rest and avoid any strenuous activities or driving until the effects wear off completely.

4. Post-Procedural Diet and Hydration

Your gastroenterologist will provide instructions regarding your diet and hydration after the colonoscopy. You may be advised to start with clear liquids and gradually reintroduce solid foods as tolerated.

Staying hydrated is crucial, especially after the bowel preparation for the procedure.

When to Seek Medical Attention

While rare, complications can arise after a colonoscopy. It is important to be aware of the following signs or symptoms and seek medical attention if they occur:.

1. Severe Abdominal Pain

If you experience severe or worsening abdominal pain that does not resolve or is accompanied by other concerning symptoms, contact your healthcare provider immediately.

2. Heavy Rectal Bleeding

If you notice heavy rectal bleeding or persistent bleeding after a bowel movement, it is crucial to seek medical attention promptly. Though mild bleeding is normal, heavy bleeding can be indicative of a more serious issue.

3. High Fever

If you develop a high fever following the colonoscopy, it may indicate an infection. Contact your healthcare provider to discuss your symptoms and determine the appropriate course of action.

4. Signs of Infection

Signs of infection, such as increased redness, swelling, or discharge around the site where the colonoscope was inserted, should be evaluated by a healthcare professional without delay.
