If the diarrhea is caused by allergic diarrhea due to allergy to sweets, it is generally not recommended to consume, so as not to aggravate the diarrhea symptoms; if one is a diabetic, usually with a blood sugar of 7.8-11.1 mmol/L 2 hours after meals, it is also not recommended to consume, so as not to affect the health with high blood sugar. In addition, except for the above special circumstances, most normal people can consume sweets in moderation after diarrhea occurs. In general, most sweets are rich in nutrients, such as starch, protein, vitamins, fat, etc. After moderate intake of sweets, they are absorbed by the digestive system and can be used as energy to replenish the body’s consumption. However, if too much sweet food is consumed, in addition to replenishing human consumption, the rest of the excess will be turned into liver glycogen in the liver, mostly from carbohydrates to fat, and stored in the body; at this stage, it may cause indigestion and gastrointestinal disorders in the body, which may easily aggravate human consumption, make patients lose appetite and gain weight, and may even aggravate diarrhea.
