  • What is Gastroenterology?

    Gastroenterology is a medical specialty area primarily focusing on the diagnosis and treatment of diseases and conditions in the digestive system. This includes organs such as the stomach, esophagus, colon, small intestine, rectum, gallbladder, liver, pancreas, and biliary system. Our doctors are all board-certified in gastroenterology so you can be sure you are in capable hands when you’re with us.
  • What is a Colonoscopy?

    A colonoscopy is a medical procedure whereby one of our skilled San Jose gastroenterologists is able to observe the lining of your rectum and colon. Our doctor will examine and look for polyps and signs of any potentially cancerous growths. Early detection of cancer can save lives as it could potentially allow us to remove the growth before it proliferates and affects other parts of your body.
  • What are Hemorrhoids?

    Hemorrhoids are blood vessels near the anus and lower rectum that are swollen and stretch under pressure, similar to varicose veins. The causes of hemorrhoids are numerous but often unknown. They could develop during strenuous bowel movements, pregnancy, stressful conditions, and more. They may also be located under the skin around the patient’s anus or inside the rectum. Hemorrhoids are typically uncomfortable, itchy, painful, and can bleed. They generally do not pose any serious health risks, but you should still consult a doctor to have them treated. Our doctors offer a variety of different treatment options for hemorrhoids, including hemorrhoid banding.
  • What is Colorectal Cancer?

    Colorectal cancer occurs when a malignant tumor grows on the inner wall of the rectum or large intestine. It is the third leading cause of cancer in both women and men in the United States. Several common risk factors for colorectal cancer include becoming older, being of African-American descent, having a genetic history of colorectal cancer, and developing colon polyps. Some colon polyps and early cancerous growths may not display any early warning signs, which is why it is important to get screened. Colorectal cancer can be diagnosed using colonoscopies or sigmoidoscopies. Treatment for colorectal cancer varies from patient to patient, though the most common treatment is surgery.

  • How often are colonoscopies needed?

    An average-risk patient is recommended to undergo colonoscopy every 10 years, beginning at age 50. Depending on the family history, prior colonoscopy results, and many other factors, then interval may be shorter.
  • Can heartburn be dangerous?

    Heartburn, also known as gastroesophageal reflux, or GERD, is very common that is usually bothersome, painful, and can contribute to a poorer quality of life. Very few who suffer from heartburn develop further complications, but only your physician can help decide the right treatment for you. These complications can include ulcers, bleeding, Barrett's esophagus (a "pre-cancerous" change in the esophagus) or cancer of the esophagous.
  • I have heartburn. Do I need an endoscopy?

    If you have had longstanding symptoms, difficulty swallowing, or other related symptoms, your physician may recommend this procedure.
  • How long does an EGD (esophagogastroduodenoscopy) take?

    The procedure itself takes approximately 15-20 minutes.
  • I can't drink the entire colonoscopy preparation. What should I do?

    If the bowel movements are clear or yellow, then you may have taken enough of the bowel prep and you may stop. If the stool is loose but dark, you could use an enema (such as Fleets). If there have been no change in the stool or if you have great difficulty, contact your physician and you will be transferred to the on-call doctor for guidance.
  • Why can't I drink any red fluids the day of the prep?

    It may cause some reddish discoloration within the bowel, and could be confused with blood.
  • Should I get screened for colon cancer?

    The standard medical guidelines state that a colonoscopy is recommended beginning at age 50. There are other indications for screening to begin at an earlier age, and these will be reviewed with your physician. There are special situations, such as in inflammatory bowel disease, in which patients are recommended to have colonoscopy, to help prevent cancer.
  • What is a hiatal hernia and do they require surgery?

    Hiatal hernias increase the likelihood of having symptoms of acid reflux. If this condition does not respond to medicine or if the hernia is larger than normal, surgery may be an option for particular patients. Most conditions are well-managed with changes to your diets and medications, however.
  • Is it safe to be on reflux medication long term?

    Yes, these medicines are quite safe and have been used for more than 25 years.
  • Which medication for acid reflux is the best?

    Usually, either over-the-counter or prescription antacids are sufficient for treating reflux. Your doctor can inform you of your best options based on your symptoms.
  • Do I need surgery for gallstones?

    If you do not have symptoms from gallstones, you usually will not require surgery. If, however, you have had multiple minor gallbladder attacks or a significant incident, you can greatly benefit from surgery.
  • What are common risks for developing stomach ulcers?

    A bacterial infection due to Helicobacter pylori accounts for nearly half of patients' ulcers. Other common risk factors include taking anti-inflammatory medication, the use of alcohol, and smoking.
