draw water from a well; draw water for a bath; the wound drew blood. Bible, John iv. 11 The woman saith unto him, Sir, thou hast nothing to draw with, and the well is deep. George Cheyne (1671-1743) Spirits, by distillations, may be drawn out of vegetable juices, which shall flame and fume of themselves.
There are two main causes of gas: swallowed air and the normal breakdown of undigested food -- especially sugar, starches, and fiber. Your body expels this gas through burps and farts. Everyone does it. In fact, when your body is healthy, it's normal to pass gas 14 to 23 times a day. Bloating can be caused by too much gas in the intestines, although you can also feel bloated and have a normal amount of gas.
It is very natural to release intestinal gas. On average, a normal adult does it as many as 15 times daily, producing anything between one pint and three pints of gas every day. However, when we say normal, it does not essentially denote being at ease. In fact, for some people even passing the standard quantity of gas may result in uneasiness, while in other people the occurrence of flatulence as well as the quantity of gas released is generally more than usual.
