When eating watermelon, there is always a small amount of watermelon seeds accidentally swallowed into the stomach, generally no effect on human health, but if a large number of watermelon seeds accidentally eat may have an impact on human health. Watermelon seeds have a hard shell that is not easily digested by the body, and the surface is accompanied by a layer of mucus, which will stick very closely to the intestinal fluid after contact. A small amount of watermelon seeds can be discharged through the gastrointestinal tract after peristalsis and will not affect the human body. If a large amount of watermelon seeds are mistakenly consumed, the mucus on the surface of watermelon seeds and intestinal fluid will be tightly bonded and cannot be expelled through gastrointestinal peristalsis, which may form intestinal obstruction. This condition may prevent other foods from being absorbed through the gastrointestinal tract and expelled from the body, resulting in symptoms such as abdominal pain, anal cessation of defecation and constipation. If you have gastrointestinal disorders such as indigestion, especially in children with an incompletely developed gastrointestinal tract, mistakenly consuming watermelon seeds will put a certain burden on the gastrointestinal tract and may aggravate existing gastrointestinal disorders, causing symptoms such as bloating and belching. The possibility of intestinal obstruction is greater for this group of people who accidentally eat watermelon seeds than for ordinary people, and can even induce intestinal perforation in severe cases. If you accidentally eat a lot of watermelon seeds and become uncomfortable, it is recommended that you seek medical attention promptly. After laboratory and imaging examinations, the disease can be clarified and the treatment plan of medication or surgery can be chosen according to the severity of the disease.
