Food Intolerance

Food intolerances may appear similar to food allergies, but they are different. A food allergy causes an immune system response, which can sometimes be severe or even life-threatening. A food intolerance, on the other hand, is typically less serious and involves some unpleasant digestive symptoms after the consumption of triggering foods.

Most of the time, when the body has a negative physical reaction to food, it is because of a food intolerance, rather than an allergy. In some cases, you may be able to consume small quantities of a triggering food without showing symptoms of food intolerance.

What causes food intolerance?

If you have a food intolerance, your body may lack an enzyme needed to digest certain foods. Digestive conditions like irritable bowel syndrome and celiac disease can also cause food intolerances. In some cases, ongoing stress or psychological issues can be linked to food intolerance.

What foods commonly cause intolerances?

Lactose intolerance is a common food intolerance, affecting about 10 percent of people in the United States. This food intolerance is a result of people being unable to digest the sugar in milk, causing an intolerance toward dairy products. People with celiac disease are intolerant to gluten, which is a protein found in wheat and grain products. Finally, some people may be intolerant to food additives, such as sulfites, which are found in wine, dried fruit, and canned goods, and others can even be intolerant to dyes and flavorings found in processed foods.

How can I treat a food intolerance?

If you notice that you commonly have a negative reaction after eating a certain type of food, you should see your doctor, who can help you to determine the cause and rule out a more serious issue like an allergy. A doctor can also help you to treat underlying issues leading to the food intolerance or come up with a plan to improve your digestion.

Common Symptoms

  • “After eating some processed foods, I become extremely bloated and gassy, and I get cramps in my stomach.”
  • “I have had to stop eating dairy products like cheese and ice cream, because when I do, I develop diarrhea, stomach pain, and heartburn.”
  • “When I consume wine, I feel nauseous, and I get a headache pretty quickly afterward.”

Beth M.
Awesome experience!!! Professional, friendly, comforting!!!! I was so nervous and every single person I encountered was wonderful… Thank you!!!😊
Cindy
Dr. Wille is a very caring, compassionate doctor! He looks you in the eye instead of typing on his computer while you talk, that is so important to me, it shows me that he is LISTENING to me and cares what I have to say. To get an appointment to see him in the office takes awhile, that's how popular he must be. I can see why. That is my only negative that I have encountered. He was timely once it was my appointment time to see him. I appreciated that since so many doctor's have you sit for awhile in the exam room waiting for the doctor to walk in. I would recommend Dr. Wille to anyone looking for a knowledgeable, caring, and compassionate gastroenterologist. Thank you Dr. Wille!
Sherry A.
Professional, kind staff. The waiting room was deceptive. Many people thought I'd be waiting a long time. In by nine, out by 11:00. Prep was the most difficult thing in a colonoscopy.

Edward J.
Dr Bologna and his staff are great. When I was called back to get prepped everyone made me feel good and relaxed. Dr Bologna popped in to check on me and explained what he was going to do. As soon as I was ready the Anesthesiologist come in and wheeled me to the surgical room while making me feel comfortable. Dr Bologna and his team were ready for me. After my procedure I woke up back in my private recovery room. Amy, my nurse, made sure I was comfortable as she got me ready to leave. The doctor came in and we had a nice chat about what he discovered and next steps.I give the whole experience a 5 out 5.
Rosemary H.

From the time you walk through the door, you're greeted with friendly people to check you in. Once you're called, you're greeted by a host of friendly people who will talk to you about what's going to happen step by step. You can ask questions and they are very knowledgeable about your procedure. When entering procedure room, your doctor and his staff introduce themselves and explain what's going to happen. Later in recovery, your driver is there and doctor explain everything to You both. Just a wonderful experience and I would request my family and friends to visit your facility whenever they need a colonoscopy. Dr. Weber is an excellent doctor. My husband sees him too and love him.
Marilyn A.
Everyone was very caring and attentive to my needs!
Matthew K.
Went in last month to get a routine colonoscopy with Dr. Nandi. He was incredibly professional and his staff was very caring and supportive. The procedure was explained to me in detail of what to expect and how long it would take. They administered the anesthesia and the next thing I knew, I was waking up in the recovery room! All I can say is this experience was the greatest 20 minute nap I’ve ever had!!Thank you Dr. Nandi and staff!!!

Dr. Donat and the entire staff are awesome. I've been a patient for over 10 years and have had the benefit of their services for two colonoscopy procedures, a barium small bowel series and an exploratory surgery consult. Each time I my experience was the same. Expert hands, caring doctor and staff, easy to schedule, consistent follow up before and after the procedures. Dr. Donat always makes time to see you, answer questions and spend as much time with you as needed. During the barium series at Beaumont Troy, the Beaumont staff expressed the love for the doctor as being the best. I agree. Thank you Dr. Donat!!

The entire staff from receptionist, medical assistant and procedure scheduler were great: Pleasant, thorough and efficient. Dr. Donat was very caring and explained everything to my complete satisfaction.
Gary S.
What an amazing surgery center with an exceptional team of consummate professionals! From the beginning with their high-tech but easy to use registration to the doctor’s time, empathy and obvious care, my colonoscopy was handled perfectly. Dr. Weber, Dr. Bakkan and their colleagues are incredible and at the top of their field. Everyone working there, including the pre- op nurse, the nurse anesthetist, the post op nurse, the reception desk and the person, who moved me, were all friendly, efficient and professional. I especially appreciated the respect for both my privacy and my time. They even beat their estimate on the time required. This was not my first colonoscopy and this surgery center experience was much better than my prior colonoscopy at a practice in a different state.I am judgmental on quality of health care as I work in a tangental field and a close relative is a surgeon. Not all doctors are high quality and patient-focused. Based on my personal experience, it is worth waiting to get an appointment with this practice.
Judith H.
Doctor was on time and staff was proficient..
DONG J.
All Staff were excellent Doctor, Nurses (information communication) A++ thank you

Chrissy C.
Dr J. Weber is an amazing Doctor. I know I'm in good hands with him. He has been my physician for many years and has always given me the best care. His staff plays a big part in my care to they all are wonderful. My procedure went well I was very confident and comfortable with the care I received. Thank you.
Kristin L.
Team is amazing. Friendly, efficient, caring and knowledgeable
Emily B.
I've said it before, and I'll say it again: Dr. Nandi is the best! I couldn't recommend him any more highly than I already do to anyone that'll listen! He has been my provider for 14 years, and I've only good things to say! Great bedside manner, incredibly skilled, caring, honest, knowledgeable, and helpful! After my last upper endoscopy, I started a new medication, Voquezna, and I am already feeling a gazillion times better. The med is super expensive, but the man works miracles, and it's being home delivered for $50 a month. That was the cheapest option, which can be expensive, but I had some samples to try out, and honestly, my gut health is worth it!! I was miserable before!Update: My prescription got covered and it is less than half of what I was paying before! A v
Marcy R.
Prep information and directions were clear and reviewed with me ahead of time. They gave me contact information if I had questions during and prior to prep. Excellent experience overall, knowledgeable team, kind warm and welcoming upon arrival and throughout. The check in Staff, spoke to me right away, very efficient and kind. Staff all made me feel as comfortable as possible in an uncomfortable situation. They got me in and out within a very reasonable time frame, little to no waiting. Dr. Willie was very friendly and had great bed side manners. Dr. Ben (anesthesiologist) was very comforting and explained everything well. My husband and I will refer our friends and family for their gastrointestinal needs. Great news, I don't have to return for 10 years, they were able to rule out my primary physicians possible concerns. I plan on returning to this location when needed. A special thank you to the entire team, including the guy with the super fun hair in the procedure room (sorry I didn't get your name)!
Steve L.
Excellent care facility. Everyone from walking in to walking out was very pleasant and helpful.
Ramona A.
I had a positive experience from the point of making my appointment through the procedure. I received reminder information before the procedure, as well as a call the day after my procedure to check on how I was doing. Thanks for caring and taking pride in what you do for others.
Steven R.
I went to the center of digestive health for a colonoscopy and Dr. Donat and his office staff and nurses were the best ! When I arrived the waiting room was packed .I had never been there before and feared a long wait . To my surprise in a few minutes they called my name to go back to pre op and the whole process from entering pre op to leaving home after my procedure was less than a hour !!’ I can not say enough on how well I was treated through my stay there !! I would highly recommend them !!
Jeanette M.
Saw Dr Willie NP and she was very professional and addressed my concerns. I would recommend Dr Willie and his staff
Michael J. Pal 5.
I've been coming here for years. I've had 3 colonoscopies and, on 10/29/24 a flexible sigmoidoscopy. In January 2024 Dr. Sante Bologna removed a precancerous polyp from my colon and now I have a clean bill of health. He has undoubtedly extended my life. Dr. Bologna and his staff are very knowledgeable and professional. All of my procedures have been very good experiences. I highly recommend Troy Gastroenterology.
Marie V.
I have been seeing Dr. Bologna for various reasons over the course of the past 25 years. He is kind and takes time to listen to a detailed medical history, and in fact, wants to know the complete story of what is going on with my health. He is a great diagnostitian and I have highly recommended him to family and friends.

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 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 a physician 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.

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. 

What insurances 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.

If you have any questions regarding your benefits or insurance coverage, please contact our Billing Department at 248-844-9710.

What if I need to contact the doctor?

To contact your doctor during business hours please call our main number 248-844-9710. If you have an urgent need to speak with the doctor after hours, you will be rerouted to our after hours answering service, and your doctor will be paged. In the case of a medical emergency please proceed directly to the nearest hospital emergency room.
