Conventional wisdom tells us that increasing the intake of green vegetables is usually beneficial to one's health. But a Taichung citizen in his seventies was recently sent to the hospital because of his frequent consumption of these healthy food items. So what is the problem here? Our next story explains.

This old man experienced vomiting and severe stomach pain and in the end, he could not eat anything.

After four days he sought medical treatment with an X-ray finding a round object in his duodenum requiring endoscopic removal.

It turned out to be dehydrated vegetable matter, a hard bezoar.

Twenty years of medical practice, and this doctor said it's the first time he has heard of such an incident.

He has heard of persimmons, celery, grapes and cordia leaves causing a vegetable bezoar stuck in the duodenum, but it is really rare.

Mr. Wu likes to eat leaf mustard and sometimes doesn't cut it up finely and eats quickly leading to lots of fiber and slow gastrointestinal motility leading to difficulty in digestion and absorption,

potentially leading to this bezoar.

Physicians remind people that this can happen to everyone from the elderly, to children and adults.

They say that in severe cases vomiting should lead to medical treatment, and in some cases, death may occur because of malnutrition, or gastrointestinal perforation, or sepsis.
