Hepatitis

Make An Appointment

Overview

Hepatitis means an inflammation of the liver. Inflammation causes painful, red swelling and occurs when tissues become injured or infected. The inflammation can cause organs to not function properly.

There are different kinds of hepatitis.

Hepatitis A usually gets better within a few weeks without treatment. Usually, getting lots of rest and avoiding alcohol will be sufficient, but if symptoms persist you should see a doctor.

Hepatitis B and hepatitis C are usually not treated unless they become chronic. If chronic hepatitis B or hepatitis C causes liver failure, a liver transplant may become necessary.

Liver Biopsy

 

What are the different types of hepatitis?

Hepatitis A is contagious and is caused by a viral infection. It typically results in a mild illness lasting a few weeks, but some cases may be severe and persist for months. People contract hepatitis A by coming consuming a food or beverage contaminated by an infected person’s fecal matter. Hepatitis B is also a viral infection, and it can be mild or chronic. Chronic cases can lead to liver cancer or liver failure and be life-threatening. The hepatitis B virus is spread through contact with blood, body fluid, or open sores from someone with the virus. Finally, hepatitis C is also caused by a virus, and it can lead to serious liver damage. Most people who contract hepatitis C, which also spreads through blood or body fluids, experience a chronic infection, which leads to complications like liver cancer and cirrhosis if not treated.

 

How can a person prevent hepatitis?

You can prevent hepatitis A and B through vaccination, but there is no vaccine for Hepatitis C. You can avoid catching this virus by refraining from sharing needles with others or from having unprotected sex. Practicing safe sex, wearing gloves when cleaning up after others, and avoiding sharing chewing gum with others are also protective measures for hepetatis B. Additional preventive measures for hepatitis A include washing your hands and avoiding raw food or tap water if you travel to a place with poor sanitation.

 

How is hepatitis treated?

There is no medication or formal treatment for hepatitis A, but your doctor may monitor your liver health to ensure that you are healing. While you are sick, it is important to rest and avoid alcohol. For hepatitis B, it is important to get treated as soon as possible after exposure, so a doctor can administer a vaccination and a hepatitis B immune globulin shot to help your body fight the infection. Your infection may go away, but if it becomes chronic, you may have to take medications to treat it. There is no treatment for acute cases of hepatitis C, but if it becomes chronic, there are also medications available to treat it. Medication is usually successful at treating hepatitis C, but if it is not, you may need a liver transplant.

 

Common Symptoms

  • “I felt extremely tired, and I had no appetite. I also began experiencing nausea and muscle pain without warning, and several days later, I had itchy skin and dark-colored urine. I had hepatitis A.”
  • “When I had hepatitis B, I had stomach and joint pain, and I had fatigue that lasted for months. I had no appetite, and my skin started to look yellow.”
  • “I started to experience dark urine, yellowing of the skin, and clay-colored poop, and I noticed that I felt tired all the time and had pretty severe stomach pain and nausea. My doctor told me I had hepatitis C.”

Hillbilly03 R.
Dr. Weber and the whole staff was super nice and on point. Hardly any wait. I also received a call later in the evening to see how i was doing.
Denise K.
I changed to Dr Willy because I wasn't getting any progress from my previous Dr. Things aren't going any differently here. He wants to schedule more tests that I've already had on more than one occasion. I had 17 ERCPs in 3 years with my previous DR. and now he wants another. I did the colonoscopy and EUS 2 years ago with Dr Willey. He said to make sure he didn't miss anything. If he missed something I don't want him as my Dr.!
Sean B.
Dr. Wille and his NP’s are Top Notch with regards to taking care of my gastrointestinal issues. I’ll be honest, I did have a bad experience with another Dr in the group and will never see him again.
Regarding Dr. Wille, he was my father’s GI doc and helped him live some 20 years after his colon cancer. As for me, I’m in my early 60’s and Dr. Wille is well aware of my family history, taking great care of me and has a great bedside manner.
I met Nicolette this week for the 1st time and she was easy to talk to (even if it is/was a difficult conversation).
Rochelle C.
The staff was very helpful and professional. The Doctor (Bakken) was very knowledgeable & very detailed in her examination and gathering my personal information & family history & events. Great experience overall!

annette E.
I recently had two procedures on June 26th, 2025. Upon arriving at the office, the staff was friendly and helpful. Check-in was seamless, and I barely waited before being called. The team efficiently gathered my information and assured me I’d be seen shortly. Within five minutes, I was in a room.

The nurse and CRNA gathered more information and then the CRNA promptly wheeled me to the procedure room. Both the assistant and doctor were already there, ready and kind. The CRNA and assistant quickly got me all set up, and before I knew it, I was awake and ready to go.

A kind staff member even escorted me to my car afterward. Overall, it was a 5-star experience!
Joann K.

Overall experience with this physician and group was exceptional. Timeliness of appointment and scheduling was flexible and an unexpected work conflict requiring a reschedule was easily accommodated. Checking in and intake were low key and the two women I worked with helped me relax. I was treated respectfully and kindly by all care extenders and the physician. Follow up call in the afternoon was appreciated.
“Senior pix” are not fun - having a great group to work with made it far easier.
Jill S.
Hands down no better doctor than Dr. Nandi. You will always know you are getting the best treatment and he always makes you feel comfortable and keeps you laughing to ease any nerves you may have.

George K.
I had a procedure this morning with Dr. Nandi at the Surgical Centers of Michigan located on Investment Drive. Dr. Nandi as always was the most professional and caring doctor that I have encountered.
But, what impressed me was the staff in the office. The TEAM (receptionist, the nurse who checked me and made me ready for the procedure, Anesthesiologist and nurse in the procedure room, the recovery room nurse, the PA who called me later in the day to check-up on me) showed me such care and compassion. It made me feel as if I was the most important patient that they would encounter.
It is obvious that these professionals love what they are doing. They love helping others. That made all the difference to me.
Thank you.
James P.
My colonoscopy with Dr. Nandi was outstanding as usual. The staff, nurses, prep crew and Doctor made the procedure go smoothly.

FAQs

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.
