Feeling sick in the morning but not pregnant

During the early stages of pregnancy, fatigue and nausea are common.

They can take a pregnancy test if there is any risk that a person could be pregnant. They can see their doctor if they are not pregnant to ascertain the source of their morning nausea.

Feeling nauseous upon waking up could simply be the product of the night before, bad sleep or an upset stomach. It may also indicate a more chronic underlying health concern, however.

Fatigue and nausea after eating

It’s fairly natural for the energy levels of a human to dip after eating. This is because, to help break down food in the stomach, the body redirects blood to the digestive system.

Since the body has more food to digest, consuming too much can cause a significant drop in energy levels. Overeating can also cause feelings of nausea or fullness.

Fatigue symptoms and nausea after eating can also signify a digestive problem. Some potential digestive disorder signs include:

When to see a doctor

It is not necessarily a cause of concern to encounter fatigue and nausea. These signs are often the result of poor lifestyle habits. Changing these habits should lead to symptoms improving or decreasing.

However, if they have serious, persistent, or worsening episodes of fatigue and nausea, people should see a doctor.

For fatigue and nausea that are followed by any of the following symptoms, it is necessary to seek immediate medical attention:

  • chest pain or pressure
  • difficulty breathing
  • slurred speech
  • persistent confusion
  • continuous or repeated vomiting
  • fever
  • yellowing of the skin or eyes
  • suicidal thoughts

A severe underlying medical condition requiring immediate medical attention may be suggested by the symptoms above.


The outlook depends on the underlying cause of these symptoms for individuals suffering combined fatigue and nausea.

Fatigue and nausea are not always a source of concern. This combination of symptoms often goes away after necessary lifestyle modifications, such as improvements in eating , sleeping, or exercise patterns.

However, episodes of fatigue and nausea that are extreme, prolonged, or chronic can suggest an underlying medical condition that needs treatment. It can take time for a physician to diagnose and treat the cause in certain cases. An individual can usually find relief from these symptoms once a doctor has developed a diagnosis and a treatment plan.


Both causes of fatigue and nausea may not be preventable. The following factors can, however, reduce the risk of a person experiencing these symptoms:

  • staying hydrated
  • limiting alcohol and caffeine intake and avoiding either before bedtime
  • avoiding large meals and eating late at night
  • getting plenty of sleep each night
  • following basic personal hygiene to help prevent infections
  • eating a healthful diet and exercising regularly to reduce the risk of health conditions that can cause fatigue and nausea
  • alleviating stress through one or more of the following:
    • mindfulness meditation
    • breathing exercises
    • yoga or tai chi
  • seeking therapy for mental health issues, such as anxiety or depression


Symptoms that usually occur together are fatigue and nausea. They are the effect of lifestyle patterns, such as insufficient sleep or diet, or lack of exercise, in some cases. They can, in other cases, signify an underlying problem of mental or physical health that needs care.

Sometimes, after using home remedies to help sleep, relieve stress, or improve nutrition, a person can experience symptom relief. However, a person should see their doctor if these changes do not lead to an improvement in symptoms.

A medical diagnosis and care should be pursued for anyone who experiences extreme, persistent, or repeated symptoms of fatigue and nausea. Many patients will experience an improvement in their symptoms following appropriate treatment.
