Whenever i eat celery sometimes i feel like i'm going to gag on the celery and today when i ate celery i gaged on the celery what does this mean. ?

Fibrous: Celery is very fibrous; break a stalk in half and you will see "strings". It is those string that may be causing the gagging. If you still want to eat celery I suggest taking smaller bites and chewing more vigorously. Otherwise there are many other crunchy veggies to try such as carrots, radishes, jicama, fennel and cucumbers, just to name a few. Best wishes.
