If you’re sick to your stomach, you may wonder if you have food poisoning or the stomach flu. The symptoms are so closely related, it can often be difficult to discern. Let’s start with some basics.

What is the stomach flu?

First of all, the “stomach flu” is actually known as gastroenteritis by your health care professional. It is a result of an inflammation of your gut (your stomach and intestines).

The stomach flu (or gastroenteritis) is caused by a virus.

What is food poisoning?

While food poisoning can also be caused by a virus, other culprits include parasites and bacteria, with bacteria being the most common causative agent.

Additionally, food poisoning is much more common than the stomach flu. It is estimated that roughly 48 million people experience food poisoning each year.
