In brief: Yes
In fact, you can have too much of a good thing.
If you drink too much water (we are talking an immense amount) or try to hold your bladder, you can retain too much water in your body. This can cause a problem with the salt concentrations in your body which can lead to a host of problems. This can include heart problems and problems with the signals of your nerves and to your muscles.

In brief: Usually not
If you are a healthy person drinking water can rarely hurt.
Your kidneys are quite efficient and removing excess water unless you overwhelm them by drinking several liters ( like 15 or more) a day. Having said that, if you have heart, kidney or liver problems, that's a whole different situation. You maybe restricted in those situations.

It is possible to drink too much water. You would have to drink well over the recommended amount of water to do this though.
This can cause the electrolytes in your blood to become dilute and can cause organs like your heart to function poorly. Drinking excess water is not known to cause weight gain unless you have kidney or heart problems that affect your ability to clear the excess water.
