A colonoscopy is part of a broader category of procedures known as an EGD. It stands for esophagogastroduodenoscopy. It includes methods like upper GI endoscopies and deals with diagnosing conditions inside your digestive system. They are some of the safest and most common surgeries your Katy TX colon specialist performs.

While endoscopy is primarily concerned with your upper digestive system and enters the body through the mouth, a colonoscopy will diagnose problems in the colon and enters the body through the rectum. It consists of inserting a tiny camera on the end of a long, thin, and flexible tube into the body. The video camera can help us find what possible condition is causing your symptoms. We can sometimes use a scope in a colonoscopy to take polyps or a biopsy during the procedure. Otherwise, it is an essential tool for cancer screening.

Give us a call today to receive your diagnosis and treatment.

Because we sedate you during a coloscopy, we will ask you to bring a friend or family member with you to drive you home. The sedation leaves you with impaired judgment and drowsy, too much to drive a car. On top of that, we are going to give you a specific diet before the procedure.

GERD (Gastroesophageal Reflux Disease)

Gastroesophageal Reflux Disease simply refers to a severe form of acid reflux. GERD is defined as mild acid reflux twice a week or more or severe reflux once a week. GERD is common itself, and acid reflux is widespread enough that everyone has experienced it before. This repeated backwash of your stomach acid up through the esophagus is what can pose serious risks. It threatens to cause an ulcer in your throat, where you cannot afford an ulcer.

Most people’s GERD is mild enough that they can manage it relatively well through a simple change in diet and over-the-counter medications. However, if your GERD is severe as we defined it, then you should make an appointment with your Katy TX colon specialist. They will be able to prescribe you more potent drugs or suggest a different treatment plan.

Helicobacter Pylori Bacteria Infections

These infections are incredibly and surprisingly common throughout the world. Estimates posit that half of all people have H. pylori living in their stomachs. Most catch the infection during childhood, but they can go their entire lives without knowing it at all. It is during old age that Helicobacter pylori pose true threats.

If Helicobacter pylori infections go untreated for too long, then they can create peptic ulcers. These are holes in the lining in your stomach. If you start having black and tarry or bloody stools and vomit, then you should seek professional help from your Katy TX colon specialist today.

Your stomach doctor will likely prescribe you two antibiotics simultaneously. This will prevent the bacteria from growing resistance to either one. They will also give you a stomach acid-suppressing drug to give your stomach lining a chance to heal.
