What Are the Causes of Sudden Nausea & Diarrhea?

Nausea and diarrhea often accompany each other. Their frequency varies depending on the individual, and typically these symptoms are not serious. However, nausea and diarrhea may signal a more serious condition, and a doctor's advice should be sought.

Viral Infections

• A virus may be responsible for these symptoms. Severity can range from minor to very serious.

Food Poisoning

• Bacteria in food that has expired or that has not been well prepared can often cause the stomach to react with diarrhea and sometimes vomiting.

Medication Side Effects

• Some medications can irritate the stomach. These side effects should be listed on the medication container, and symptoms should not be severe.

Bowel Disorder

• Sometimes a medical disorder in the bowels can cause diarrhea. If you think you might be suffering from a disorder within your intestines, talk to a doctor about what can be done.

Traveling

• Drinking the water from other geographical areas may cause sudden diarrhea. This is because bacteria in the water may be unfamiliar to you.
