It's not bad to get up in the middle of the night to pee as long as it's only 1 or 2 times per night.
I get up in the middle of the night to pee sometimes at least 1 time and there's nothing wrong with me but if you're getting up to pee more than a couple times per night then it could be a health issue that needs looking into.
You may have an overactive bladder, or if you're a man you could have an enlarged prostate which there are medications for.
Having an enlarged prostate is not a serious health issue but medication and surgery can help with the enlarged prostate.
When you take the enlarged prostate medication it will help stop you from having to wake up in the middle of the night to pee.
But if you're only going pee 1 or 2 times through the night then it's likely nothing to worry about.
My husband only needs to pee in the morning when he wakes up and when he does wake up in the morning he really, really needs to pee really bad.
He has a large bladder and can hold it for hours but not me.
I have to go pee a lot sooner than him.
