When to seek medical help

If you believe that you have consumed a toxic substance or if you are very dehydrated, you should seek medical assistance as soon as possible.

If you have been unable to eat or drink for more than 12 hours due to your sickness, you should consult a doctor. If after trying over-the-counter therapies for nausea for 24 hours, it has not subsided, you should make an appointment with your primary care physician.

If you have any reason to believe that you are having a medical emergency, you should never hesitate to seek medical attention.

How is nausea treated?

The treatment for nausea is contingent on the underlying reason.

For instance, those who suffer from motion sickness may find that sitting in the front seat of a car provides some relief. Medications such as dimenhydrinate (Dramamine), an antihistamine, or the application of a scopolamine patch can be helpful in the treatment of motion sickness. Scopolamine patches can also be used to treat seasickness.

Medications that target the underlying cause of nausea can also be helpful in treating the symptom. For instance, drugs that decrease stomach acid are used to treat gastroesophageal reflux disease (GERD), and medications that alleviate pain are used for severe headaches.

After your nausea has subsided, making sure you drink enough water can help you avoid being dehydrated. This includes consuming frequent, tiny sips of transparent liquids, such as water, or a beverage containing electrolytes, such as a sports drink.

When you start to reintroduce food, it is advisable to keep to the BRAT diet (bananas, rice, applesauce, and toast) until your stomach is more settled. This diet consists of bananas, rice, applesauce, and toast.
