Gas and Bloating Gastroenterologists (GI Doctors) NYC

Gas and Bloating GI doctors nycYou always have some intestinal gas within your digestive tract.  Gas in your digestive tract (the esophagus, stomach, small intestine and large intestine) comes from two sources- swallowed air and the normal breakdown of certain undigested foods by harmless bacteria that are naturally present in the large intestine.

Air swallowing (aerophagia) is a common cause of gas in the stomach.  Everyone swallows small amounts of air when eating and drinking.  However, eating or drinking rapidly, talking while eating, chewing gum, smoking or wearing loose dentures can cause some people to take in more air.  Burping or belching is the way most swallowed air leaves the stomach.  The remaining gas moves into the small intestine where it is partially absorbed.  A small amount travels into the large intestine for release through the rectum and expelled as flatulence.If you suffer from excess gas, either trapped in your intestines or passed as flatulence, it can become uncomfortable. Stuck gas can cause abdominal pain and bloating. In truth, everyone passes gas several times a day. Even stuck gas is a normal part of the digestive process.

Gases are also  produced as a by product when certain food materials are digested by naturally occurring bacteria in the large intestine or colon.  These bacteria are responsible for digesting materials like complex carbohydrates (sugar, starches and fiber found in many foods) and cellulose, which are not normally digested in the upper gastrointestinal tract.   The quantity and mixture of gases depends on the types of bacteria in the colon.  Everyone has a unique assortment of bacteria from the time of birth.  These gases include hydrogen, carbon dioxide, and methane.  Trace gases, such as hydrogen sulfide, are responsible for the odor.

Symptoms and Causes of Gas and Bloating

The most common symptoms of gas are belching, flatulence, bloating and abdominal pain. The sensation of abdominal bloating can be a symptom of gas alone but can also be a symptom of several serious conditions such as ovarian cancer, diverticulitis and many other causes of abdominal pain in general which need to be taken seriously.

Patients with irritable bowel syndrome (IBS) can begin to experience symptoms of bloating, abdominal pain and motility changes to specific food components.  This may be due to the IBS condition itself which can cause  a change in the gut microflora, potential small intestinal bacterial overgrowth (SIBO) and visceral hypersensitivity.  Visceral hypersensitivity is the term used to describe an experience of pain within the inner organs  at a level that is more intense than normal.  This means that there may  be symptoms from a more intense than usual response to a normal amount of gas.

Celiac disease which (gluten sensitive enteropathy) is a digestive and autoimmune disorder that results in damage to the lining of the small intestine when foods with gluten are eaten.  The condition can cause  many gastrointestinal symptoms which including abdominal bloating but also can include pain, gas, diarrhea, and weight loss.  Non-celiac gluten intolerance may also play a role in patients with IBS.  There  is recent evidence that certain food components can contribute to symptoms through the effects of malabsorption of carbohydrates particularly lactose and fructose.   Identifying components of the diet which may not be fully absorbed such as lactose and fructose in particular may be helpful in minimizing these symptoms.  Further, identifying and treating patients with risk factors and symptoms of small intestinal bacterial overgrowth (SIBO) can also help with symptoms of bloating.  Small intestinal bacterial overgrowth (SIBO) simply is a disorder of excessive bacterial growth in the small intestine.

Diagnosing Gas and Bloating 

Gas and bloating is usually a temporary condition that resolves itself in a day or two. If gas and/or bloating become painful, however, you should see your doctor or a gastroenterologist like Dr. Khodadadian. If your gas and bloating is accompanied by other symptoms, such as diarrhea, bloody stools, vomiting, constipation, heartburn or unexplained weight loss, a visit to the doctor also is recommended.

During your office visit, Dr. Khodadadian will give you a physical exam and review your medical history and any recent dietary changes. Since gas and bloating sometimes can be symptomatic of a more serious condition, Dr. Khodadadian may order laboratory tests.

Many gastrointestinal disorders exhibit similar symptoms. Fortunately, hydrogen breath tests now are available to uncover the source of some gastrointestinal disorders. This procedure makes it easier for Dr. Khodadadian to diagnose certain medical conditions, such as:

  • Fructose intolerance
  • Lactose intolerance
  • Small intestinal bacterial overgrowth (SIBO)

The above conditions results from your body’s inability to absorb a dietary carbohydrate or from a condition that promotes abnormal bacterial growth in your digestive tract. These disorders create a specific chemical response that can be measured in your breath, leading to an accurate diagnosis.

Why You May Need Hydrogen Breath Testing

All three conditions listed above can cause gas and bloating, cramping, diarrhea and even nausea or vomiting in some people. These symptoms aren’t by themselves dangerous, but they can make daily life unpleasant, and if left untreated — or worse, if you have it and don’t know it — you continually place stress on your digestive system.

Since the symptoms caused by these disorders are the same as from many other medical conditions, diagnosis can be difficult. The hydrogen breath test helps Dr. Khodadadian pinpoint a more accurate diagnosis. The hydrogen breath test is not a wonder drug or a new electronic gizmo; it’s simple chemistry.

Treating Gas and Bloating

Treating gas and bloating depends on the seriousness of the diagnosis. If you smoke cigarettes, quitting can help resolve your gas and bloating. Reducing your stress also may help. Often, treatment simply means avoiding certain foods or medications. Although everyone reacts differently to food, here is a list of basic foods to avoid:

  • Beans and other lentils
  • Brussels sprouts
  • Broccoli and cauliflower
  • Cabbage and lettuce
  • Excessive bran and fiber
  • Certain fruits, like apples and pears
  • Chewing gum
  • Hard candy
  • Carbonated drinks, including beer

You also can try an assortment of over-the-counter products to reduce your gas and bloating, if it’s mild enough. These products can help you fully digest certain foods, especially if you know ahead of time that you’ll be eating them. Other products can help reduce the odor of your flatulence. These products are safe to use, but only address the symptoms, not the cause of your gas and bloating. Breath testing can be used to identify certain triggers of symptoms in the general population as well as patients with irritable bowel syndrome.
