Can allergies make you have nausea?

Yes, allergies can make you have nausea. When you have an allergic reaction, your body releases chemicals called histamines. Histamines can cause a variety of symptoms, including nausea, vomiting, and diarrhea.

If you have a history of allergies and you are experiencing nausea, it is important to see a doctor to rule out an allergic reaction. Your doctor can also recommend ways to manage your allergies and prevent future reactions.

In addition to nausea, allergies can also cause other symptoms, such as:

* Sneezing

* Itchy eyes

* Runny nose

* Congestion

* Difficulty breathing

* Hives

* Swelling

* Anaphylaxis (a severe, life-threatening allergic reaction)

If you are experiencing any of these symptoms, it is important to see a doctor to get a diagnosis and treatment.
