What preparations are needed before a rectal and colonoscopy examination?
Anorectal and colonoscopy examinations are common medical tests used to assess the internal condition of the intestines, helping doctors diagnose intestinal diseases. To ensure the accuracy and smooth progress of the examination, patients need to do some preparatory work before the test.
Anorectal and colonoscopy examinations are common medical tests used to detect the internal condition of the intestines and help doctors diagnose intestinal diseases. To ensure the accuracy and smoothness of the examination, patients need to do some preparatory work before the examination. Here are the preparatory matters before anorectal and colonoscopy examinations:
1. Dietary Adjustment
Three days before the examination, patients should mainly consume light and easily digestible foods, avoiding spicy, greasy, and hard-to-digest foods. The day before the examination, a low-fat, low-fiber diet is recommended, avoiding foods rich in fiber such as vegetables and fruits. On the morning of the examination, patients should fast and not eat.
2. Intestinal Cleansing
To observe the internal condition of the intestines more clearly, patients need to undergo intestinal cleansing before the examination. Usually, doctors will provide patients with oral cleansers, such as laxatives, to clear the feces from the intestines. Patients should take them according to the time and amount instructed by the doctor to ensure the intestines are fully emptied.
3. Medication Preparation
If patients are taking long-term medications, they should consult their doctor before the examination to see if they need to pause. This is especially important for anticoagulants, antiplatelet drugs, and non-steroidal anti-inflammatory drugs that may affect examination results or increase the risk of bleeding. Additionally, if patients have chronic diseases such as diabetes or heart disease, they should inform the doctor before the examination so that the doctor can assess the risks and adjust the treatment plan.
4. Clothing Preparation
On the day of the examination, patients should wear loose and comfortable clothing to facilitate the procedures during the examination. It is also recommended to bring a blanket or mat to keep warm during the examination.
5. Psychological Preparation and Informed Consent
Patients should understand the process, purpose, and risks of anorectal and colonoscopy examinations. If there are any questions or concerns, they should consult the doctor in a timely manner. Before the examination, patients need to sign an informed consent form, indicating that they fully understand and agree to undergo the examination.
6. Other Precautions
Before the examination, patients should avoid vigorous exercise and maintain good rest and sleep. If patients have symptoms such as fever or cough, they should wait until the symptoms subside before undergoing the examination. Additionally, female patients who are menstruating should wait until after their period is over before undergoing the examination.
In summary, the preparation before anorectal and colonoscopy examinations is an important step to ensure the smooth conduct and accurate results of the examination. Patients should follow the doctor's guidance and make all necessary preparations to ensure the examination proceeds smoothly.

Single-use visual endoscopes: A new trend in the medical industry
Explore the application and future development of disposable visual endoscopes in the medical industry, and understand the convenience and innovation they bring.
Single-use endoscopes are expected to make a leap in the Chinese market.
Endoscopes, known as the "eyes" of doctors. Since the 19th century, endoscopes have undergone multiple iterations and updates, from rigid endoscopes, flexible endoscopes, electronic endoscopes to capsule endoscopes, and so on. In recent years, a newer type of disposable endoscope has been applied in clinical settings, serving as a complement to traditional reusable endoscopes.
Endoscopes mainly enter the body through natural or surgically created small openings. They are equipped with optical lenses and mechanical devices, allowing for the observation of diseased tissues once inside the body. This type of instrument is collectively referred to as an endoscope in clinical settings, including bronchoscopes, colonoscopes, gastroscopes, hysteroscopes, cystoscopes, laparoscopes, and arthroscopes.
How will single-use endoscopes change the way you undergo health check-ups?
With the continuous advancement of medical technology, disposable endoscopes are changing the way we conduct health examinations. As an advanced medical device, disposable endoscopes bring innovation to health checks with their unique advantages. This article will explore how disposable endoscopes are impacting our health examination methods.
