Here are answers to some common questions about proactive Gastrointestinal care with Dr. Nicholas Agresti:

What is a Gastroenterologist?

A gastroenterologist is a specialist physician who is highly trained in the health of the digestive system, including the esophagus, stomach, intestines, colon, liver, gallbladder, and pancreas. They are experts in diagnosing and treating digestive conditions and performing preventive screenings, such as 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, those with a family history of colon cancer or other risk factors may need to start earlier. Dr. Agresti will determine the best, personalized screening schedule for you.

I have frequent heartburn. When should I be concerned?

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

Can hemorrhoids be treated without surgery?

Yes, most hemorrhoids can be effectively managed with lifestyle and diet changes. For persistent internal hemorrhoids, Dr. Agresti can perform simple, painless in-office procedures like hemorrhoid banding.

What are some common signs of liver problems I should watch for?

Common signs of liver problems include jaundice (yellowing of the skin or eyes), persistent fatigue, abdominal swelling, and unexplained dark urine. If you experience any of these symptoms, please schedule a consultation with Dr. Nicholas Agresti for a thorough evaluation.

What is the role of diet in managing IBS?

Diet plays a crucial role in managing IBS. Dr. Agresti 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.

What is Celiac Disease?

Celiac disease is an autoimmune disorder where consuming gluten, a protein found in wheat, triggers damage to the lining of the small intestine. While gluten sensitivity shares some symptoms, a proper diagnosis from a gastroenterologist is crucial before adopting a gluten-free diet.

Are there non-colonoscopy options for colon cancer screening?

Yes, there are non-colonoscopy options like at-home stool-based tests. However, a positive result on these tests still requires a colonoscopy to confirm the findings and remove any suspicious polyps. Colonoscopy remains the gold standard for both detecting and preventing colon cancer.
