COLONOSCOPY: WHAT YOU NEED TO KNOW





A colonoscopy remains one of the most effective ways to detect and prevent colorectal cancer before it becomes a serious threat. During the procedure, doctors can find and remove precancerous polyps, significantly lowering your chances of developing colorectal cancer later on. Studies consistently show that getting a colonoscopy every 10 years—recommended for most adults at average risk—not only saves lives but also costs less over time compared to other screening methods like yearly fecal occult blood tests (FOBT) (Annals of Internal Medicine).

Medical experts generally advise starting regular colonoscopy screenings around age 45 or 50, depending on your health history, and repeating them every decade if no issues are found. This timeline is supported by substantial evidence showing colorectal cancer rates stay very low within ten years of a clean colonoscopy (BMJ). If colorectal cancer or certain polyps run in your family, your doctor might suggest beginning screenings earlier or doing them more often (Gastroenterology). Since guidelines evolve with new research, it’s a smart move to regularly check in with your healthcare provider about what’s right for you (World Journal of Gastroenterology).

Colonoscopy plays a key role beyond just cancer prevention. For people with inflammatory bowel disease, it’s a vital tool to monitor the condition and catch any early warning signs of cancer (Arquivos Brasileiros de Cirurgia Digestiva).

Alongside these screenings, there are lifestyle choices you can make to protect your colon. Eating a diet rich in fruits, vegetables, whole grains, and lean proteins helps keep your digestive system healthy. Limiting red and processed meats, reducing alcohol intake, and quitting smoking all lower your cancer risk. Regular exercise and maintaining a healthy weight also contribute to colon health. If you’re unsure how to start making these changes, consider working with a health coach for personalized guidance. ProTime-Fitness.org offers solid resources to help.

If you’re nearing the recommended screening age or have risk factors, set up a time to talk with your doctor about colorectal cancer screening. Combining early detection through colonoscopy with healthy habits boosts your chances of staying cancer-free and enjoying better overall health down the road.

DIABETES: CAUSES, SYMPTOMS, MANAGEMENT, AND PREVENTION    Diabetes is a complex, chronic condition that comes in several forms, each with its own causes, risks, and best ways to manage it.  Diabetes alters how your body uses insulin, a substance produced in the pancreas, required by cells to absorb sugar in the form of glycogen. When glycogen is unavailable to your cells, they lack an energy source. The two most common types of diabetes are Type 1 and Type 2 diabetes. Type 1 is primarily an autoimmune issue—your own immune system mistakenly destroys the insulin-producing cells in your pancreas (Nature Reviews Disease Primers) There are rare, less-understood forms as well, often linked to genetics. Type 2 diabetes, which accounts for over 90% of all cases, develops when your body becomes resistant to insulin or doesn’t make enough of it (Nature Reviews Disease Primers; NY.gov). Symptoms can be similar to Type 1, but often develop more gradually and can also include blurred...

    Diabetes drugs may reduce the risk of Alzheimer’s. The study finds people taking the drugs have fewer biomarkers, slower cognitive decline. People taking certain drugs to lower blood sugar for type 2 diabetes had less amyloid in the brain, a biomarker of Alzheimer's disease compared to people with type 2 diabetes who are not taking the drugs and those without diabetes. The new study, published in the August 11, 2021, online issue of  Neurology , the medical journal of the American Academy of Neurology, also found people taking these drugs, called dipeptidyl peptidase-4 inhibitors, showed slower cognitive decline than people in the other two groups. In people with type 2 diabetes, the body no longer efficiently uses insulin to control blood sugar. Dipeptidyl peptidase-4 inhibitors, also known as gliptins, can be prescribed when other diabetes drugs do not work. They help control blood sugar when combined with diet and exercise. "People with diabetes have been shown to ...
