The organ that chili affects is mainly your gastrointestinal tract, most specifically your mouth, stomach, esophagus and intestines.
The Capsaicin in chili is what mainly affects your gastrointestinal tract, including your mouth, intestines, esophagus, stomach and intestines.
The capsaicin triggers the body's pain and heat receptors, which creates the burning sensation on your tongue and mouth and signals that brain that you're overheating, which can result in sweating and even a runny nose.
As you swallow, the chili, the capsaicin in the chili and chili peppers triggers receptors along the chest area, which causes a burning sensation or discomfort that is often referred to as and known as acid reflux or heartburn.
Moderate amounts of chili and chili peppers and capsaicin can also increase your metabolic rate temporarily as well as temporarily boost production of mucus.
But excessive consumption of chili and chili peppers and capsaicin can irritate your stomach lining, which can lead to nausea, cramping or aggravated stomach ulcers.
The capsaicin in chili peppers and other spicy foods also speeds up motility of the gut, which helps digestion or ease constipation in some people, although it can also result in diarrhea or a burning sensation during bowel movements in some people.
And your liver acts as a central organ in metabolizing and detoxifying the capsaicin, which has protective and anti-inflammatory and anti-oxidant properties for liver health.
If you have any conditions like GERD or acid reflux, or irritable bowel syndrome, IBS, then you're much more sensitive to the effects of chili on these organs.
Spicy foods are good for you in moderation, but too much spicy foods can be bad for your health.
So you should consume spicy foods including spicy chili in moderation or if you're sensitive to the spices you can leave out the hot spices.
