Here is something interesting I got from Wikipedia. I also looked up cholic and the Mayoclinic said it's when your baby cries. However, if you look up horse cholic you get a better article.
"Gas and spasmodic colic[edit]
Gas colic, also known as tympanic colic, is the result of gas buildup within the horse's digestive tract due to excessive fermentation within the intestines or a decreased ability to move gas through it.
[6] It is usually the result of a change in diet, but can also occur due to low dietary roughage levels, parasites (22% of spasmodic colics are associated with tapeworms),
[7] and
anthelminthic administration.
[6][8] This gas buildup causes distention and increases pressure in the intestines, causing pain.
[6] Additionally, it usually causes an increase in
peristaltic waves, which can lead to painful spasms of the intestine, producing subsequent spasmodic colic. The clinical signs of these forms of colic are generally mild, transient,
[8] and respond well to spasmolytic medications, such as
buscopan, and
analgesics. Gas colics usually self-correct,
[8] but there is the risk of subsequent torsion (volvulus) or displacement of the bowel due to gas distention, which causes this affected piece of bowel to rise upward in the abdomen.
[6]
Abdominal distention may occasionally be seen in adult horses in the flank region, if the cecum or large colon is affected.
[6] Foals, however, may show signs of gas within the small intestines with severe abdominal distention.

So I'm a horse.
