Gas

Encyclopedia of Alternative Medicine by Paula Ford-Martin

Gas, or flatus, is produced when naturally occurring bacteria in the gastrointestinal tract begin to break down, or digest, food. When an excess of air builds up in the tract from swallowing air or a disorder that prevents digestion, it is released as gas. Gastrointestinal gases include methane, carbon dioxide, nitrogen, and hydrogen.

Gas production is an essential, normal function of the gastrointesinal tract, and most healthy individuals pass up to 1,200 cc (over 40 oz) of gas each day. However, when gas causes excessive pain and cramping (colic) then evaluation and treatment are appropriate.

Gastrointestinal gas production can be increased by certain foods, illnesses, and some medications. Common causes of excessive gas include:

• Gas-producing foods. Onions, beans, the cabbage family, and other fibrous foods can cause excessive gas or intestinal spasms in some individuals.
• Gastrointestinal diseases and disorders. Increased flatulence is a defining symptom of irritable bowel syndrome , diverticulitis, lactose intolerance, malabsorption problems, dysbiosis (digestive problems), and other gastrointestinal disorders.
• Air swallowing. Swallowing too much air while eating or chewing gum can introduce extra gas to the gastrointestinal tract.
• Medications. Certain prescription and over-the-counter medications may cause gas as a side-effect.
• Stress and food allergies can also cause gas.

Symptoms of excessive gas production include:

• flatulence
• belching, or burping
• abdominal cramping, or colic
• abdominal pain

A thorough medical and dietary history and physical examination performed by a healthcare professional can usually identify the cause of gas pains resulting from changes to diet or medication. Gas problems triggered by gastrointestinal disease may be harder to diagnose, and will typically require additional medical testing such as colonoscopy, barium enema, or an upper and/or lower gastrointestinal (GI) series.

For excessive gas caused by a particular food or beverage, adjustments to diet can relieve most symptoms. Gas caused by air swallowing can be alleviated by eating more slowly and avoiding gum chewing.

An herbalist or naturopathic healthcare professional may recommend a preparation of a carminative (gas reducing) herb such as valerian (Valeriana officinalis), or peppermint (Mentha piperita), which may be helpful in eliminating discomfort and gas-related bloating.

Homeopathic remedies for excessive intestinal gas include Carbo vegetabilis, Nux vomica, and Chamomilla. The prescription of a specific homeopathic remedy will depend on an individual's overall symptom picture, mood, and temperament, and should only be prescribed by a qualified homeopathic physician.

Hydrotherapy, acupressure, acupuncture, yoga, reflexology, and mild exercise can also help to relieve the pain and discomfort of excessive gas.

Over-the-counter preparations of the enzyme alpha-D-galactosidase (Beano) can alleviate gas symptoms caused by ingestion of certain foods in some individuals. These preparations are typically available in liquid or tablet form. Other non-prescription medications such as Gas-X, Phazyme, and Mylanta contain the ingredient simethicone, which can reduce gas bubbles within the gastrointestinal tract.

Mild excess gas is typically easy to treat, especially that triggered by dietary causes. Gas caused by gastrointestinal disease may be more difficult to manage, and successful treatment depends on the type and severity of the disorder.

Avoiding fermented foods, drastic increases in fiber intake, and excessive air intake can prevent gas in some individuals. Lactose intolerant individuals should avoid dairy products.
