Food Poisoning

Unfortunately, food can sometimes be contaminated with bacteria, which lead to food poisoning. Nausea and a lack of appetite are usually symptoms felt with food poisoning. You might also experience stomach cramping or fever. 

Food poisoning is not contagious and can often be managed at home. It is important to try to replace any fluids lost through vomiting or diarrhea. Try taking small sips of water throughout the day or drinking oral rehydration solutions can be helpful to keep you hydrated.

It is when you are at risk for dehydration that you should seek care at an urgent care center. Other reasons to seek immediate care can include: 

  • A fever
  • Blood in your stools
  • Diarrhea lasting more than three days
  • Persistent vomiting


Norovirus is a very contagious virus that can cause symptoms of nausea, vomiting, lack of appetite and diarrhea. 

How is norovirus spread? Often through direct contact with someone who is infected. Sometimes contaminated food or water is found to cause norovirus. Finally, if you touch contaminated surfaces and do not wash your hands properly you can contract norovirus. 

Norovirus is common and can often be treated at home. By using good hygiene and washing surfaces in the home well, you can help to slow the spread to other family members.

Certain medications have side effects that can cause nausea or a lack of appetite. Common medications that cause these symptoms include: 

  • Antidepressants
  • Antibiotics
  • Blood Pressure Medications
  • Chemotherapy

Sometimes taking medication with some food can help with nausea. Still, if the side effects are affecting your wellbeing, your doctor may need to reassess the medication dosage or explore other treatment options. 

Stress or Anxiety

Loss of appetite and nausea are often experienced under stressful situations or chronic anxiety. Nausea is often one of the most common symptoms of anxiety. Other common symptoms can include shaking, a rapid heartbeat, and difficulty breathing. 

Therapy and medication can help address feelings of anxiety. You can also take an inventory of what is causing stress in your life to see what changes can be made.


Nausea and lack of appetite are common symptoms in early pregnancy. Usually, once the pregnancy has reached 14 weeks, the symptoms subside. 

Obstetricians recommend the following to help with nausea early in pregnancy: 

  • Eat small but regular meals that are tolerable to you
  • Drink small sips of fluid regularly throughout the day
  • Try drinking beverages that include ginger, including ginger ale or tea
  • Eat dry crackers right away in the morning before getting out of bed

Suppose you are unable to drink fluids and are at risk for dehydration. In that case, it is essential to report this to your obstetrician as soon as possible or visit urgent care if you need immediate hydration therapy.
