Deflation, an economic inconvenience or a serious problem

Economic deflation refers to a decline in general price levels, often caused by a reduction in the supply of money or credit.

Deflation can also be brought about by direct contractions in spending, either in the form of a reduction in government spending, personal spending, or investment spending.

Deflation has often had the side effect of increasing unemployment in an economy, since the process often leads to a lower level of demand by people for products in the various economic areas.

flatulence (noun) (non countable)
1. Excessive gas, or air, in the stomach and intestines.
2. The production of a mixture of gases or air in the digestive tract of mammals or other animals that are byproducts of the digestion process.

Such a mixture of gases is known as flatus, and is expelled from the rectum in a process colloquially referred to as "passing gas".

Under certain circumstances, food particles from the small intestine may pass undigested through the large intestine (the area where the fermentation process is facilitated). When the bacteria present in the colon attacks these undigested materials, the resulting gas gives the flatus its characteristic odor.

Causes of Stomach and Intestinal Gas

  • Excessive belching which takes in more air than is expelled.
  • Consumption of abnormal amounts of carbonated beverages.
  • Swallowing air while eating.
  • Bacterial action on ingested foods.
  • Air which is swallowed and forced into the intestinal tract by peristalsis (wavelike muscular contractions in organs of the digestive system; such as, the esophagus and the intestines).

Peristalsis is characterized by alternate contraction and relaxation, which pushes ingested food through the digestive tract towards its release at the anus.

flatulency (s) (noun), flatulencies (pl)
1. Windiness in the stomach; air generated in a weak stomach and intestines by imperfect digestion, occasioning distension, uneasiness, pain, and often belchings.

3. Airiness; emptiness; vanity.

flatulogenic (adjective), more flatulogenic, most flatulogenic
Tending to cause, or to produce gas that is trapped in the digestive system: "Certain foods can be considered as flatulogenics or "gassers"."

"Some foods are flatulogenic, earning them the reputation of being the top flatus producers; including, beans, bran, broccoli, Brussels sprouts, cabbage, cauliflower and onions. For some people, beer, carbonated beverages, and milk can also be flatulogenic."

There are some foods that are mildly flatulogenic; such as, apples, apricots, bananas, carrots, celery, all citrus fruits, cucumbers, eggplant, lettuce, potatoes, prunes and raisins, radishes, soybeans and spinach can all be classified under these flatulogenic groups."

flatulogenous (adjective), more flatulogenous, most flatulogenous

2. Expelling of gas, or air, from a body orifice; especially, the anus: "The passing of flatuses may average a dozen a day in some people and up to a hundred times in others."

"The foul smell usually is caused by small traces of gases; such as, hydrogen sulfide, ammonia, and methane."
