Hunger Pangs Explanation: Causes and Why They Occur
Stomach rumbling and hunger pangs are common sensations that many of us have experienced at some point in our lives. While these feelings are often associated with hunger, they can also be caused by a variety of other factors.
Hunger pangs, characterized by a gnawing or rumbling sensation in the stomach, can feel like abdominal pain, a feeling of emptiness in the stomach, and painful contractions in the stomach area. These sensations occur due to the release of the hormone ghrelin when the stomach is empty, causing contractions in the muscles of the stomach and intestines [1].
Stomach rumbling, on the other hand, is the noise produced by the movement of gas and fluids in the digestive system, caused by the contraction of the muscles in the stomach and intestines. This noise is usually harmless and is a normal part of the digestive process [1]. However, if the noise is coming from the lower part of the abdomen, it may be the food passing through the small and large intestines and making that noise.
However, it's important to note that stomach rumbling and hunger pangs can also be caused by factors unrelated to true hunger. For instance, swallowing air, drinking carbonated beverages, or having an empty stomach can all contribute to these sensations [1].
Dehydration can also cause hunger pangs as the body may mistake thirst for hunger. Therefore, it's essential to stay hydrated, especially during a fast or when dieting [2]. When dieting, it's crucial to ensure you're eating enough protein and consider protein-based diets [3].
Certain medications can cause stomach pain or upset, leading to hunger pangs. Consuming a diet mostly consisting of processed foods may not be nourishing the stomach as well as thought, leading to hunger pangs [4].
Stress can trigger hunger pangs, and irregular eating patterns, poor diet, sedentary habits, high stress levels, and other lifestyle factors can affect gut motility and function, contributing to digestive discomfort and rumbling noises regardless of actual hunger [5].
Gastrointestinal and digestive issues, such as lactose intolerance, celiac sprue, constipation, or irritable bowel syndrome (IBS), can cause hunger pangs. If you're experiencing new or unusual hunger pangs, it's important to seek medical attention to rule out any underlying medical conditions [6].
If the source of stomach grumbling is due to hunger, there's no way to stop the sounds, and the best remedy is prevention: Plan ahead and eat at least one to two hours prior to any important events. However, if the grumbling persists or is accompanied by concerning symptoms like shortness of breath, constipation or diarrhea, blood in stool, vomiting, nausea, headache, weakness, difficulties sleeping, rapid fluctuations in weight, or any other symptoms that don't feel right, it's crucial to consult a healthcare provider [7].
In summary, stomach rumbling and hunger pangs without true hunger are often caused by digestive processes like gas movement, incomplete food digestion, gut motility patterns, swallowed air, functional or structural GI disorders, and lifestyle factors rather than actual caloric need [1][3][5]. If accompanied by concerning symptoms (pain, weight loss, persistent nausea), medical evaluation is advised [4].
So, the next time you feel hunger pangs and any loud rumblings, remember to give your body what it needs: A nice balanced meal and regular exercise. Eating slowly, mindfully, and at similar times each day can help manage these sensations. But if they persist, don't hesitate to consult a healthcare provider.

- A protein-based diet can be beneficial when dieting, as it ensures you're eating enough protein to aid in good health and muscle recovery, but it's important to do so while maintaining a balanced diet for overall wellbeing.
- Stress, irregular eating patterns, poor diet, sedentary habits, high stress levels, and other lifestyle factors can affect gut motility and function, contributing to digestive discomfort and rumbling noises that may result in hunger pangs. Incorporating health and wellness practices, such as a balanced diet and regular exercise, can help mitigate these effects.
