Gastroenterology is the branch of medicine that concentrates on the diagnosis and treatment of the disorders of the digestive system. Included are disease affecting the gastrointestinal (GI) tract, that is the organs from mouth to anus, along the alimentary canal: esophagus, stomach, intestines, liver, gall bladder, pancreas. Proctology focuses on the lower GI tract, specifically on colonic, rectal and anal diseases.

Many gastroenterological diseases, often initially an inflammation or hemorrhoid problems, are easily and rapidly treatable or preventable if seen early by gastoenterologists. Yet other diseases such as GI tract tumors, that require immediate surgical intervention. Early detection and diagnosis is in all cases the best way to cure the disease.

You should seek a gastroenterologist's help with the following symptoms:

  • Digestion problems
  • Bad breath
  • Reflux or heartburn (it happens when the acid contents of the stomach splash back into the esophagus) and is accompanied by a painful burning feeling in your chest or throat.
  • Gallbladder problems
  • Abdominal distension (stomach bloating), sensation of feeling uncomfortably full often with the presence of abdominal rumbling sounds
  • Abdominal discomfort: pain, cramps, spasms
  • Constipation
  • Chronic diarrhea
  • Frequent bowel stimulus
  • Feeling of fullness (after eating)
  • Dizziness or faintness, nausea (vomiting)
  • Rectal bleeding (of bright red blood)
  • Blood in stool: black or tarry stool or dark blood mixed with stool any be sign of bleeding in the lower digestive tract. Bleeding in upper digestive tract may also cause bright red blood in vomit or vomit that looks like coffee grounds
  • Rectal problems such as rectal discharge, mucus, lumps or swelling
  • Burning, pain, itching, inflammation, swelling, irritation around the anus

You should see the doctor if you experience any of the following:

  • Diarrhea for more than 3 days
  • Severe pain in the abdomen or rectum
  • High fever
  • Blood in your stool or black, tarry stools
  • Signs of dehydration

Gastroenterological and/or proctologic examination

The aim of the examination is the detailed assessment of the patient's discomforts and symptoms, investigation of the causes and the efficient diagnosis, treatment and, where possible, prevention, of diseases of the GI tract. The examination includes full anamnesis (patient history), physical examination, including, where required, ultrasound and endoscopic imaging examination and laboratory tests, as necessary. The physical examination may include digital rectal exam and rectoscopy (the endoscopic examination of the rectum and anal cavity).

Our specialists will advise on lifestyle and dietary changes that can help prevent diseases.

Ultrasound imaging and rectoscopic examinations and procedure if required for screening or treatment of rectal disorders are performed in Coral Medical Center in ambulatory setting. This procedure is normally done to inspect for hemorrhoids or rectal polyps and might be mildly uncomfortable but not painful. Modern fiber-optic rectoscopes allow more extensive observation with less uneasiness. A local anesthetic will further ease discomfort.

Among our activities:

  • Diagnosis and treatment of GI diseases
  • Identification of risk factors and exacerbants and advise/treatment to reduce disease risk and help prevention.

Some of the diseases we diagnose and treat:

Gastro-esophageal reflux disease (GERD), a highly prevalent condition characterized by regular and frequent "heartburn" and/or acid regurgitation experienced after a large meal. The symptoms are usually pain, a sour taste in the mouth, and occasionally vomiting blood or blood in the stools (melena).

Gastric and duodenal ulcer. Extremely frequent, an ulcer occurs when the acidic digestive juices, which are secreted by the stomach cells, corrode the lining of these organs. Ulcers are caused by bacteria called "Helicobacter pyloricus" (H. pylori). Other causes include the chronic use of anti-inflammatory medications (NSAIDs or nonsteroidal anti-inflammatory drugs, including aspirin) and cigarette smoking.

Helicobacter Pylori treatment. H pylori is very common, infecting more than a billion people worldwide. H. pylori is found in more than 80% of patients with gastric and duodenal ulcers. It has been established that elimination of this bacteria heals ulcers and prevents recurrence. Treatment is important also because a H pylori infection seems to be the cause of most stomach cancers.

Inflammatory bowel diseases

Crohn's disease. Crohn's disease is an inflammatory bowel disease that causes swelling in the intestines, often accompanied by pain and diarrhea. Crohn's disease can affect any area of the GI tract but it is most common in the lower part of the small intestine, called the ileum.

Colitis Ulcerosa. It is another form of inflammatory bowel disease limited to the colon with the rectum involved in more than 95% of cases. Its causes are not known. With colitis ulcerosa, frequent episodes of rectal bleeding occur, with or without mucus. The characteristic feature is blood in each bowel movement.

Rectal diseases See more on these diseases in our Proctology page by following the Proctology link at the bottom of this page.

Hemorrhoids. The condition in which the veins around the anus or lower rectum are swollen and inflamed. Hemorrhoids may result from straining to move stool but can appear in other conditions such as pregnancy, aging, chronic constipation or diarrhea.

Rectal inflammation, also known as proctitis. It can occur at any age and is often accompanied by bleeding and pain. In severe cases, the inflamed rectum may release a pus or mucus discharge. Rectal inflammation can be caused by a variety of different factors, ranging from sexually transmitted diseases to autoimmune diseases.

Functional disorders The diseases called "functional" are those conditions in which either the muscles of the organs or the nerves that control the organs are not working normally, and, as a result, the organs do not function normally. This applies to muscular organs of the gastrointestinal tract-esophagus, stomach, small intestine, gallbladder, and colon. Doctors call "functional" those diseases in which – and as long as - the abnormal functioning of the organ involved cannot be seen with either the naked eye or the microscope. Making the diagnosis in these cases usually involves excluding other illnesses.

Dyspepsia (indigestion or non-ulcer dyspepsia). Symptoms of dyspepsia originate primarily the stomach and first part of the small intestine and include: upper abdominal pain, belching, nausea (with or without vomiting), abdominal bloating (the sensation of fullness), early satiety after a very small amount of food, and, possibly, abdominal swelling. Eating most often provokes the symptoms.

Non-cardiac chest pain. This pain may mimic heart pain, but it is not associated with heart disease but results from a functional abnormality of the esophagus.

Irritable bowel syndrome, or IBS (spastic colitis, nervous colon syndrome) presents with abdominal pain, bloating, irregular bowel habits with alternating diarrhea and constipation. Up to half of patients with IBS also have symptoms of dyspepsia. IBS is a common disorder that tends to be chronic and can cause chronic recurrent discomfort, but it does not normally lead to any serious organ problems.

Non-cardiac chest pain. This pain may mimic heart pain, but it is not associated with heart disease but results from a functional abnormality of the esophagus.

Chronic diarrhea. Prolonged diarrhea persisting for more than a couple of days may be a sign of a more serious problem and poses the risk of dehydration.

Constipation (medically speaking, constipation usually is defined as fewer than three bowel movements per week). Acute constipation requires urgent assessment because a serious medical illness may be the underlying cause. Constipation also requires an immediate assessment if it is accompanied by symptoms such as rectal bleeding, abdominal pain and cramps, nausea and vomiting, and involuntary loss of weight.

Diverticulosis of colon. This is the condition of having small pouches ("diverticula") in the lining of the colon, or large intestine that bulge outward through weak spots. Some people with diverticulosis may experience crampy pain or discomfort in the lower abdomen, bloating, and constipation. The pouches may become inflamed; the condition is called diverticulitis. The most common symptom of diverticulitis is sudden severe abdominal pain. Diverticulitis can lead to bleeding; infections; small tears, called perforations; or blockages in the colon, complications that always require treatment to prevent them from progressing and causing serious illness.

Liver, pancreas and gallbladder diseases, gallstones

Liver diseases can manifest in many different ways. Characteristic manifestations include jaundice (a yellowish discoloration of the skin and whites of the eyes), cholestasis (reduction or stoppage of bile flow), but symptoms may include fatigue, a feeling of unwellness, loss of appetite, and mild weight loss.

Pancreatitis. It is an inflammation of the pancreas, which may acute or chronic. It usually presents with abdominal pain and can cause nausea and vomiting. The acute inflammation occurs suddenly with severe abdominal pain. The condition requires immediate medical attention as it may lead to internal bleeding and infection. The most common cause of acute pancreatitis is blockage of the pancreatic duct by gallstones. Chronic pancreatitis is characterized by chronic or persistent abdominal pain develops gradually and its main causes are gall bladder disease and alcoholism.

Digestive system tumor screening and prevention

Tumors can develop throughout the digestive system. In Western countries, colorectal cancer (of the large intestine and rectum) is one of the most common types of cancer and the second leading cause of cancer death. Colorectal cancer grows slowly and does not cause symptoms for a long time. Early diagnosis therefore depends on routine screening. This is very important because colon cancer is most likely to be cured if it is surgically removed early.

Medex Screen Test breakthrough computerized diagnostics

Medex is an innovative, breakthrough medical device for early diagnosis and screening of diseases of internal organs, a fusion of medical science and hi-tech interpretive computer program.

An early diagnostic screening device, the Medex Test can detect numerous organ-related diseases, and functional disorders (including cancers) often, even before anatomical abnormalities appear.

It provides a highly accurate diagnosis of the internal organs in a non-invasive, non painful and X-Ray free, 20 minute examination. It is suitable for all age groups above six years.
