When I eat spicy food I feel bad but my stress is relieved. So, on stressful days, many people reach for spicy food. After I train my tongue and sweat a lot, I feel like my stress is relieved. However, even if stress is relieved at mealtime, the problem arises later. If you eat too much spicy food, you may experience not only stomach pain but also burning pain and burning in the anus. Why does my anus hurt the day after eating spicy food?

The brain perceives spicy flavors as pain. Our tongue can only perceive sweet, salty, sour and bitter taste. The reason food tastes spicy is due to capsaicin, which binds to the vanilloid receptor (TRPV1), also known as the capsaicin receptor, on the tongue. These receptors serve to transmit stimulation to the brain, and our brain recognizes this stimulation as pain caused by heat. That’s why you feel a tingling sensation on your tongue.
Spicy ingredients in the seasoning, such as red pepper and black pepper, are not absorbed by the digestive system and are excreted through the feces. The problem is that the nerves around the anus are similar to those in the mouth. Therefore, after eating spicy food, you feel a burning sensation in the anus. The small amount of capsaicin contained in peppers etc. it is completely absorbed in the large intestine and is not excreted through the anus. However, in foods like Buldak or Maratang, which are rich in capsaicin, the capsaicin that is not absorbed in the large intestine is excreted through feces. At this time it binds again to the capsaicin receptor in the anus. Just like when you eat it, you feel pain due to the heat. In other words, you feel a burning sensation in the anus because the area of pain has changed from the tongue to the anus.
Additionally, acidic substances generated during the digestion of spicy food can irritate the anus, causing a hot sensation. These irritations can inflame the tissues around the anus or irritate the skin, causing burning and pain.
The amount and distribution of capsaicin receptors vary from person to person. People who eat spicy foods well have fewer capsaicin receptors, so less pain is transmitted to the brain. Additionally, some people feel no pain because their anus has fewer capsaicin receptors. This means that not everyone feels a burning sensation in the anus when eating spicy foods.
Meanwhile, spicy food actually helps relieve stress. This is because the brain that feels pain secretes endorphins. Endorphins are hormones that relieve pain and stress and their secretion increases as pain increases. However, spicy foods damage the gastric mucosa. Therefore, if you are a person with a weak digestive system, it is better to avoid too spicy foods and wait about 3 days.
