  • Are gallstones serious?

    The answer is yes, they can be serious. Most of the time, gallstones are asymptomatic meaning it does not cause any symptoms, in this case we leave them alone. They can cause significant inflammation of the gallbladder which is called cholecystitis and will require removal of the gallbladder. They can also called pancreatitis (inflammation of the pancreas) as well as obstruction of the passage of bile from the liver into the small bowel which can lead to infection. Your diet is very important. Should not be eating diet consistent with high fat. If you develop symptoms, you should see PCP or surgeon for further evaluation. READ MORE

  • How often should you have an endoscopy for GERD?

    EGD for GERD is typically only recommended for certain patients and unless you have Barrett's esophagus, there is no need for repeat Endoscopy. We perform EGD to exclude other causes of your symptoms such as ulcers, H pylori infections and to rule out Barrett's esophagus in patients with chronic reflux >10 years, obesity, diabetes, males over age 40, family history of Barrett's or esophageal cancer, weight loss, trouble swallowing. We can also perform Endoscopy in patients when GERD is not controlled on medications. In this case we can perform BRAVO testing in which, we attach a capsule in the lower esophagus, to measure how much acid you are having. If you have reflux and other symptoms, you should speak to a Gastroenterologist to see if you would require an EGD. READ MORE

  • How is gastritis caused?

    Gastritis means inflammation of the stomach. This has many causes. the main causes in a young patient are NSAID use ( ibuprofen, aleve etc). These can also cause ulcers. Other causes are Alcohol use, Helicobacter Pylori infection, autoimmune gastritis etc. This is usually seen on Endoscopy ( EGD) so if your symptoms are still persistent despite using proton pump inhibitors (omeprazole etc) for 4-6 weeks then I recommend you see a Gastroenterologist to see if EGD is needed.
