Cold weather doesn’t mean staying inactive. Winter walks, snowshoeing, indoor yoga, stretching, and light strength training can all help keep digestion moving and reduce bloating and constipation.

Staying active supports overall gut function and pairs well with hydration and a balanced diet during the winter months.

Who Should Have a Colonoscopy and How Often?

Most adults should begin colonoscopy screening at age 45, or earlier if there is a family history of colorectal cancer or certain risk factors. For individuals with normal results, screenings are typically repeated every 10 years.

Colonoscopies are one of the most effective tools for preventing colorectal cancer through early detection.

Fiber plays a vital role in digestion by promoting regular bowel movements, supporting gut bacteria, and helping reduce the risk of colon polyps and diverticular disease.

A fiber-rich diet can also improve cholesterol levels and blood sugar control. Many adults fall short of daily fiber needs, making nutrition counseling an important part of GI care.

Hepatitis refers to inflammation of the liver and includes several types.

Hepatitis A and B are preventable with vaccines, while Hepatitis C is now highly treatable with modern antiviral medications.

Early testing and treatment are key to protecting liver health and preventing long-term complications.

What Is an EGD and What Is It Used For?

An EGD, or upper endoscopy, allows gastroenterologists to examine the esophagus, stomach, and upper small intestine. It is commonly used to evaluate symptoms like chronic heartburn, difficulty swallowing, unexplained nausea, abdominal pain, or bleeding. This minimally invasive procedure helps diagnose conditions such as GERD, ulcers, and inflammation.

Colon Polyps – What They Are and Why They Matter

Colon polyps are growths that form on the lining of the colon. While many are harmless, some can develop into colorectal cancer over time. Risk factors include age, family history, smoking, obesity, and inflammatory bowel disease. Regular colonoscopy screenings allow polyps to be detected and removed early, significantly reducing cancer risk.

Ulcers – What They Are and Symptoms

Stomach and duodenal ulcers are open sores that develop in the lining of the digestive tract. Common symptoms include burning stomach pain, bloating, nausea, indigestion, and in some cases bleeding. Ulcers are often caused by H. pylori infection or long-term use of certain medications. Early diagnosis and treatment can prevent complications and relieve discomfort.
