If it's just one fixture, both cold and hot water; Pull the aerator off the end of the spout and see how clogged up it is.
If it's one fixture and its either hot OR cold; You have either a rubber washer working loose on the stem OR the stop valve below the fixture on that
line has the same problem.
If it's multiple fixtures within one room, but only cold or hot; look for bad valves on the water line going to that room.
If it's multiple fixtures with both cold and hot, in multiple rooms; either the pressure reducing coming into the house is bad OR the main shut off
valve is partially blocked OR the screens on the meter set have been partially clogged.
Let us know what you find....
