Conditions We Treat

GERD

It’s more than just heartburn.

Gastroesophageal reflux disease (GERD) is a serious form of acid reflux or acid regurgitation.

BARRETT’S ESOPHAGUS

Barrett’s Esophagus is a condition caused by intestinal metaplasia, when the tissue lining the esophagus is replaced by tissue that is similar to the lining of the intestine.

CELIAC DISEASE

Celiac disease is a digestive disease that interferes with the absorption of nutrients, and causes damage to the small intestine.

COLON POLYPS

A colon polyp is a growth on the surface of the large intestine, or colon. While some colon polyps are benign, meaning they are not cancer, other types of polyps may already be cancer or can become cancer later.

CIRRHOSIS

Cirrhosis is a condition in which the liver malfunctions due to chronic injury, and scar tissue replaces healthy liver tissue.

CROHN’S DISEASE

Crohn’s Disease, which may also be known as ileitis or enteritis, is a disorder that causes inflammation of the digestive tract.

PANCREATITIS

Pancreatitis is inflammation of the pancreas, a large gland behind the stomach.

FAQ

Frequently asked questions.

What happens during my first visit?

If you are a new patient, you can expect to have a complete physical exam. You will also be asked detailed questions about your current problems and your past medical history, your current medications, allergies, your family history and other pertinent medical information. If you are taking medications, please bring a completed medical history form with you to your appointment. Once the physician has reviewed your medical information and completed the physical examination, a plan of care will be developed. You may need to be seen again in the office, be referred back to your family physician for follow-up care, or require additional testing. If additional tests are needed, we will assist you in scheduling these tests.

What insurance do you accept?

We accept payment from most insurance companies including Medicare, Blue Cross/Blue Shield, Blue Care Network, Physicians Health Plan, Cofinity, Sparrow Professional Health Network, Medicaid, McLaren, Health Plus, and several others. Accepted insurances are subject to change at any time without notice.

If your insurance requires an authorization from your primary care physician, you may be asked to assist us in obtaining this authorization.

All patients are responsible for all copays and deductibles at the time of service.

How do I get test results?

We ask that you wait 10 to 14 days before contacting us for results. Often results come from several different sources. This information needs to be compiled and reviewed by your physician before you can be appropriately advised. You may contact our office at any time to be directed to a triage nurse.

What if I need to schedule an endoscopic procedure?

An endoscopic procedure allows the physician to visualize a part of your gastrointestinal tract with a special instrument called an endoscope. If your family physician has ordered testing, you will be contacted by telephone by one of our staff members. If one of our physicians orders testing and you are in the office, the procedure can generally be scheduled during the course of your visit. You will be given a date, time, and location for the test, as well as written instructions telling you how to prepare for the test. If you have any questions about the procedure, please feel free to ask one of our staff members or the physician.

What if I need to contact the doctor?

To contact your doctor during business hours please call our main number (248) 985-2962.

If you have an urgent need to speak with the doctor after hours, you will be directed to our answering service, and the doctor on call will be paged. In the case of a medical emergency please proceed directly to the nearest hospital emergency room.

I’ve been a patient of Dr. Weber for almost a decade. My husband for more than & it was he who recommended Dr. Weber. He’s knowledgeable & well experienced in his field. Plus he’s an all around kind & nice guy. And you’d like how the office & tech staff are trained to run the operation of this practice. Efficient, patient and helpful! I’d feel very comfortable recommending this practice.

I had a great time. Everyone was very friendly and professional. One nurse said I had nice eyes, which really helped my self esteem. Dr. Willie was fantastic. His concern about having magenta ink for the printer really shows what a caring man he is. The pictures turned out great. I framed them and hung them up on my wall at home. But, seriously the experience was pleasant. Thank you to everyone involved.

Terry M.

Lord knows having a colonoscopy is zero fun. The prep nearly did me in. But after arriving at suite 270 every single person was pleasant and efficient. The attention to cleanliness in the office is very apparent and appreciated. Every employee introduced themselves by name, apologized for an IV that took two tries and made sure I was as comfortable as can be before I was ready to leave. However, I’m going to enjoy every minute of the five years before I need to return!

Marie C.

I have been here several times and have always been treated great. The receptionist are so kind and the nurses are wonderful so is the anesthesia person are so kind and answers any concerns you might have. My Dr Bologna is awesome. This is the place to go if you need endoscopy or colonoscopy. Thank all the staff for being so kind
