Are random single hiccups throughout the day considered persistent hiccups? It is only one hiccup at a time and comes at different times throughout the day. Probably about 10-15 times a day but always just a single hiccup. The hiccups are also silent. I have been having them every day, for the last three weeks. I do have acid reflux & anxiety. I am an otherwise, healthy and active 23 year old female. I would really like to know if a single hiccup multiple timea a day is considered persistant?
