What We Commonly Think About Nausea?

Everyone roughly has an idea about what nausea is. Most describe it as abdominal discomfort and an urge to vomit.


If you think that nausea occurs only due to contaminated food, then you’re not alone. It’s a common misconception that nausea and vomiting are triggered by bad food.

Many cases of nausea and vomiting happen after taking questionable food. But that’s not the only cause. There are many reasons why you might feel nauseous. And oftentimes, these have nothing to do with your food intake. So, these can trigger vomiting on an empty stomach. For example, nausea can happen due to drug side effects, central nervous system disorders, metabolic disorders, GI tract disorders, etc.

Besides these reasons, nausea can also be triggered due to an empty stomach. Let’s see how this works.

Feeling Hungry and Nauseous at the Same Time – What Are the Causes?

So, how does an empty stomach trigger nausea? There are a few possible factors that we can consider to explain this phenomenon. Let’s take a look at these:

Stomach Acid

You’ve probably heard by now that there is a type of acid in your stomach. There is a particular type of cell in the innermost layer of your stomach. These cells are called parietal cells. These parietal cells can make a powerful acid called hydrochloric acid.


This hydrochloric acid helps break down the food that you eat. This acid also kills most of the harmful bacteria in the food. So, this acid is very important for your body’s normal function.

But, this acid is harmful to the cells of your stomach too. To protect itself, there are cells in your stomach that secrete mucous fluid. This creates a thick mucous layer that protects the normal cells.

Normally, the acid that your stomach makes works against the food. But when you’re on an empty stomach, the acid can be too much for the mucous layer. Then, the acid can damage the cells of your stomach.
When you’re nauseous, the lower esophageal sphincter might loosen up. The lower esophageal sphincter is sort of a guard at the junction between the esophagus and the stomach. This sphincter prevents stomach contents from going to the esophagus.

Now, if this is loose, the stomach acid can go to the esophagus. The cells of the esophagus will be damaged if that happens. All of these factors can stimulate the nerves in the stomach and the esophagus. And this can ultimately lead to the feeling of nausea.


Hypoglycemia may be another cause of nausea with an empty stomach. ‘Hypo’ means low, ‘glyc’ means glucose and ‘emia’ means in the blood. So, hypoglycemia means low blood glucose.

When you’re on an empty stomach for long periods, you can sometimes get hypoglycemia. This is very dangerous. Because your brain runs on glucose. Low blood glucose can hamper the brain’s normal function.


So, your body tries to correct hypoglycemia by itself. So, hypoglycemia normally doesn’t happen among healthy individuals. There are other ways your body can make glucose in the absence of food.

One of those ways is through the activation of the sympathetic nervous system. This can help in increasing the glucose content of the blood. But, overactivity of the sympathetic nervous system can lead to nausea.

Other Causes of Nausea in an Empty Stomach

So, you can feel nauseous just for having an empty stomach. But nausea can be due to causes unrelated to your food intake. So it is possible that you’ll feel nauseous due to these conditions even on an empty stomach. In these cases, there are other symptoms. So, let’s take a look at a few:

Medication Side Effect

Nausea and vomiting are common side effects of many medications. Nausea and vomiting are complex responses with many pathways. Different drugs can activate different parts of these pathways and cause nausea.

So, if you’ve recently started on a new medication, then it can be responsible for your nausea.


Morning sickness is a common phenomenon in pregnancy. You’ll feel nauseous and may even vomit early in the morning. So, if you suspect that you might be pregnant, it’s best to take a test to be safe.

Motion Sickness

Motion sickness occurs when the movement of a vehicle you’re riding stimulates your vestibular system. Your vestibular system can sense movement and helps you keep balance. So, If you’re feeling nauseous when you ride any vehicle, then this might be the cause.


Gastrointestinal Disease

Gastrointestinal infections are the most common cause of nausea. However, these are associated with taking bad food. Other than these, there are a few gastrointestinal conditions that can cause nausea on an empty stomach. These are:

Metabolic Disorders

These are conditions where the hormonal balance of the body is often disturbed. These conditions can cause nausea too. Some of the causes are:

  • Adrenal diseases like Addison’s disease
  • Diabetic ketoacidosis
  • Hyper or hypothyroidism
  • Paraneoplastic syndrome

Central Nervous System Conditions

You might feel severe nausea if you have any condition affecting your brain. The nausea is very sudden and severe in this case. And you might feel severe headaches too. Some of them are:

  • Head injury
  • Raised intracranial pressure
  • Brain tumor
  • Cerebral hemorrhage

But rest assured, these causes are not as common as the others mentioned above.

Other Conditions

Nausea is associated with a few other conditions as well. For example, some psychiatric disorders like anorexia, bulimia, stress disorders, etc. can be associated with nausea. Other miscellaneous causes include glaucoma, heart attack, nephrolithiasis, etc.

What to Do if You Feel Hungry and Nauseous at the Same Time?

As you’ve read that nausea can sometimes be caused by some serious conditions. So, if you suddenly feel too much nausea on an empty stomach, it’s best to see a doctor.

This can help rule out any serious conditions. You might also consider paying a visit to the doctor if you have other symptoms with nausea.

  • If you’re just feeling nauseous, then you can try some of these steps at home:
  • You can try eating at smaller time intervals. That way, you’re stomach will not be empty for too long.
  • Staying hydrated is key to avoiding nausea
  • You can try consuming ginger, peppermint, fennel powder, cinnamon, etc. These are known to reduce nausea.
