Being too hungry can cause feelings of nausea. Eating certain types of food may help. But nausea can also occur with other health conditions that may need medical treatment.
Yes. Not eating can make you feel nauseous.
This may be caused by a buildup of stomach acid or stomach contractions caused by hunger pangs.

To help break down food, your stomach produces hydrochloric acid. If you don’t eat for a long period of time, that acid can build up in your stomach and potentially lead to acid reflux and nausea.
Hunger pangs are rarely caused by a medical condition. They’re usually attributed to your stomach being empty.

If you tend to feel nauseous when your stomach has been empty for a long period of time, consider eating at shorter intervals.
It’s not completely proven if a diet with six small meals a day is healthier than one with three larger meals. But eating smaller amounts of food with less time in between those meals may help prevent nausea.
However, Tufts University warns that if you eat a higher number of meals throughout the day, you should be eating less at each sitting compared to what you would eat if you ate less meals per day.
Tufts also noted that eating less than three times per day may make it harder to manage your appetite.
Try experimenting with the frequency of meals and the amount consumed at those meals.
It’s likely you’ll be able to find a plan that suits your lifestyle, keeping you satisfied, energized, and at a healthy weight while avoiding nausea from hunger.
Your healthcare provider or a dietician can help you create a diet and complementary meal plan based on your needs.
