Unusual Gurgling Sounds from Kitchen Sink

Over the last few days, I’ve noticed something unusual happening with the plumbing in my house. Whenever water is used in the bathroom, I can hear gurgling sounds coming from the kitchen sink, which never happened before. It doesn’t seem to affect functionality yet, but the sound is definitely new and a bit concerning. The house isn’t brand new, so I’m wondering if this could be related to ventilation or a developing blockage. Has anyone experienced similar symptoms and figured out what was causing it?
