Why does my stomach gurgle when I’m not hungry?

Stomach gurgling when you’re not hungry is usually normal. The sound is called borborygmi, and it happens when the muscles of your digestive tract move food, liquid, gas, and digestive juices through your stomach and intestines.

Common reasons include:

1. Normal digestion and peristalsis

Wave-like muscle contractions called peristalsis push contents through your digestive system. As they move through narrow sections of the gut, they can make rumbling, bubbling, or gurgling sounds.

2. Gas in the digestive tract

More gas can make the sounds louder. Gas can come from:

• Swallowed air — from eating quickly, drinking through a straw, chewing gum, or talking while eating
• Bacterial fermentation — gut bacteria break down certain foods, especially some high-fiber or hard-to-digest carbohydrates, and produce gas

3. The fasting “housekeeping” cycle

Between meals, the digestive system has a cleaning pattern called the migrating motor complex (MMC). This can create noticeable rumbling even when you don’t feel hungry.

4. Stress or anxiety

Stress can affect the gut-brain connection and change how your intestines move, which may make gurgling more noticeable.

5. Food intolerances or triggers

Some foods can increase gas or speed up digestion, such as:

• FODMAPs like onions, garlic, beans, and some fruits
• Lactose if you’re sensitive to dairy
• Carbonated drinks like soda or sparkling water

If the gurgling is occasional and not paired with other symptoms, it’s usually not a concern. But you should see a doctor if it comes with persistent pain, severe bloating, nausea, vomiting, diarrhea, constipation, blood in the stool, or unexplained weight loss.
