• Pyloric Stenosis: While often diagnosed in newborns, understanding the risk factors for pyloric stenosis can help ensure early intervention and minimize the need for extensive surgical treatment.

Here are answers to some common questions about proactive Gastrointestinal care with Dr. Daniel Gassert:

What is a Gastroenterologist?

Dr. Gassert and our team are gastroenterologists, meaning we are specialists trained to diagnose and treat conditions related to your digestive system, including the esophagus, stomach, intestines, colon, liver, gallbladder, and pancreas. We also perform preventive screenings like colonoscopies.

When should I get my first screening colonoscopy?

For average-risk individuals, routine screening colonoscopies are now recommended to begin at age 45. However, individuals with a family history of colon cancer or other risk factors may need to start earlier. Dr. Gassert will determine the best, personalized screening schedule for you.

Is the preparation for a colonoscopy difficult?

Many patients have concerns about colonoscopy prep, but modern solutions are much easier to tolerate than in the past. A clean colon is essential for a thorough exam and to identify and remove polyps. This one day of preparation is a small investment for your long-term health.

What is H. pylori?

H. pylori is a common type of bacteria that can live in the stomach. In some people, it can cause gastritis and ulcers. It can be easily detected with breath or stool tests and effectively treated with a course of antibiotics.

I have frequent heartburn. When should I be concerned?

While occasional heartburn is common, frequent or worsening symptoms (more than twice a week) warrant a consultation with Dr. Gassert. This could be a sign of GERD, which can lead to more serious problems if left untreated. Dr. Gassert can diagnose the cause and create an effective treatment plan.

What are gallstones?

Gallstones are small, hard deposits that can form in the gallbladder. Many people have them without any problems. They only become a concern if they cause blockages, leading to pain, which Dr. Gassert can help diagnose.

What is the difference between Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS)?

Inflammatory Bowel Disease (IBD), including Crohn's disease and ulcerative colitis, is an autoimmune condition causing inflammation and damage to the gastrointestinal tract. Irritable Bowel Syndrome (IBS), in contrast, is a functional disorder that causes symptoms like cramping and bloating without visible inflammation or damage.

What is the role of diet in managing IBS?

Diet plays a crucial role in managing IBS. Dr. Gassert can help identify trigger foods and recommend dietary approaches, such as the low FODMAP diet, to significantly reduce symptoms like bloating, gas, and abdominal pain.
