Our Specialties

Services

Examples of the gastrointestinal disorders Dr. Shim treats.

Celiac disease

Celiac disease is an autoimmune disease involving the small intestine in which people cannot tolerate a protein called gluten.

Colon Cancer

More than 100,000 Americans develop colorectal cancer every year, and it’s the second-most common cause of cancer deaths among men and women combined.

Colonoscopy

Colonoscopy is a highly effective colon exam. In fact, it could save your life by detecting colon cancer early or removing potentially precancerous polyps.

Constipation

Virtually everyone suffers from constipation sometime during their life, but when it continues long-term and causes serious discomfort, it’s time to get help.

Crohn's Disease

Inflammatory bowel diseases like Crohn’s disease and ulcerative colitis affect as many as 1.6 million Americans.

Diverticular Disease

Diverticulosis refers to the presence of small out-pouchings (called diverticuli) or sacs that can develop in the lining of the gastrointestinal tract.

Early gastric cancer (EGC) screening

Cancer of the stomach, or gastric cancer, is a disease in which stomach cells become malignant (cancerous) and grow out of control, forming a tumor.

Endoscopy

An endoscopy is a minimally invasive procedure to examine your digestive tract for disease or irregularities.

Fatty Liver

Fatty liver disease is a common condition that can develop into serious inflammation, scarring, and liver failure.

Gastroesophageal Reflux Disease (GERD).

When you have weeks of acid reflux and heartburn and episodes more than twice per week, you may have developed gastroesophageal reflux disease (GERD).

Heartburn

Heartburn is associated with acid reflux, a condition in which stomach acid flows back up into your esophagus and causes burning in your chest.

Hemorrhoids

Hemorrhoids are swollen veins in the lowest part of your rectum and anus.

Hepatitis

Hepatitis is a disease that causes inflammation of the liver. It can be either acute (lasting less than six months) or chronic (lasting more than six months).

Peptic Ulcer Disease (Ulcers)

Peptic ulcer disease occurs when the stomach acid penetrates the stomach or intestinal lining and causes ulcers, an often painful sore in the lining.

Ulcerative Colitis

If your immune system goes into overdrive, it can trigger ulcerative colitis, a disorder causing cramps, diarrhea, and other uncomfortable symptoms.

Elaine Camin

I appreciate Dr. Shim's direct-yet-sensitive style of delivery. My appointments are very thorough and I have never felt rushed. I just told the office today she reminds me of an "auntie"

Pierre Restel

She has amazing bed side manners, a great staff, and she is very helpful and personable, and professional.  I need to leave her practice since I'm moving out of state and I will miss her as my gastroenterologist.  I have ulcerative colitis and felt completely secure in her and her staff's care.  I highly recommend her practice.
