Is it always a sign that you're hungry?
Often, it's your gut making the noise
A growling stomach isn't always due to hunger. The sound frequently comes from your intestines, where digestion is actively moving food and gases through your system. This explains why rumbling can persist even after eating—your gut is simply doing its job.
Your stomach can rumble too
The stomach churns food, mixing it with gastric juices to prepare it for the intestines. When empty, it contracts around air and gases, producing those familiar gurgles. Eating introduces solids that dampen the noise during kneading.
