Eating too much spicy and irritating food can lead to a hot and painful anus the next day, which is a relatively common phenomenon in life. Because the active ingredient of chili peppers is capsaicin, capsaicin can make the nerves secrete more dopamine after eating, producing a more exciting and refreshing feeling. However, capsaicin cannot be completely digested in the intestine, and will remain in the stool the next day and be discharged from the anus with the stool, which will stimulate the skin and mucous membrane around the anus and produce a hot and spicy feeling when defecating. If you have this feeling, it is because eating chili peppers exceeds the body’s tolerance level, so it produces this feeling. If you can’t bear it, it’s best to eat a little less chili and less spicy and irritating food. If the pain is unbearable, you can apply hemorrhoid cream externally and keep using it for about two days to get good relief.
