It depends. Colic caused by blockage of feed (like grain) happens when the horse doesn't chew the food well enough for it to be properly digested.
If your horse is experiencing stomach pains after eating too much grain you should call your equine Veterinarian immediately as the horse is showing signs of colic and could possibly develop Laminitis.
Nope. just use a handful of bran
Spasmodic colic is believed to be the most common cause of intestinal colic. Spasmodic colic can be caused when a hot horse drinks cold water. It can also be caused by fear or stress, therefore flighty, nervous, high-strung horses are more susceptible to spasmodic colic than a calmer, more laid back, "bomb proof" horse. Impaction colic is very common as well. It can be caused by the horse eating a lot of feed or roughage such as hay and/or grass and not having enough water to drink. It can be caused by bad or moldy feed or the horse not chewing its food properly (another reason to keep your horses teeth checked) There is also Flatulent Colic, also known as Tympanic colic. It's more the indigestion type colic which causes a lot of gas and pain, normally caused from eating too much grain or grass or eating moldy or bad feed.

Spasmodic colic is thought to be the most common colic. It can be caused by a hot horse drinking cold water or too much water, which is why exercised horses should be cooled off before being allowed to drink. It can also be caused by eating too much grass or grain or eating bad or moldy food. It can also be caused by fear or stress, therefore nervous or high strung horses are more susceptible to spasmodic colic than calmer, more laid back horses.
I would suspect colic. This can kill horses. Get him to the vet. Now.

To cure colic, you need to give your horse antispasmodic medicine which can be bought from the shop. If your horse is under or overweight, it will be at greater risk of colic.
In real life, feeding a horse directly after riding can result in colic. Since colic is a very serious disorder that can result in death, feeding right after riding is not recommended. Neither is giving too much water after riding.
Colic or founder. Depending on the symptoms. In horse isles case the answer is founder.
YES YES YES YES! They can colic which often leads to surgery and even in some cases death! Eating too much of anything can cause colic. Some horsees colic easier than others but it is a HORRIBLE thing to go through.
The most important survival adaptation is that they can survive on the grain that is fed to them by humans. Horses are not meant to eat grain, but grass or hay, and that's why some horses have problems with ulcers and colic.
