A pattern of gas and bloating may be an indication that a tumor is growing, especially if it worsens or is accompanied by bleeding.

The more general term glucose syrup is often used synonymously with corn syrup, since glucose syrup is in the United States most commonly made from corn starch.
Corn Syrup: Corn syrup is extracted from corn starch and is made into glucose. Some recipes call for corn syrup as a sweetener and it is sold in grocery stores, often under the brand name Karo. High-Fructose Corn Syrup: HFCS goes through additional processing. Three different types of enzymes are added, one after the other, to change the corn starch into first glucose and then into fructose.
