Nausea and vomiting can make you feel miserable. But it's important to remember that these are not diseases. Rather, they are symptoms of many illnesses.
Nausea is a feeling of uneasiness in the stomach often tied to an urge to vomit. Nausea doesn't always lead to vomiting, though. Vomiting is the emptying of the contents of the stomach through the mouth.
These are some of the more common causes of nausea and vomiting:
Gastroenteritis, an inflammation of the digestive tract most often caused by a viral or bacterial infection
Medicines or medical treatments, such as chemotherapy
Hormonal changes, such as those that lead to morning sickness during pregnancy
Food poisoning or food intolerance
Poisons, toxins, or chemicals in the blood, such as alcohol
Stress and excitement in children ages 2 to 6
These are less common causes:
Blockage of the bowel
Pancreatitis, or other inflammation in the abdomen such as diverticulitis and appendicitis
Inflammatory bowel disease
Delayed stomach emptying
Here are ideas on how to ease nausea:
Drink clear or ice cold beverages.
Sip beverages slowly.
Eat saltine crackers, plain bread, and other bland foods.
Don't eat foods that are fried or sweet.
Eat smaller meals.
Wait a while after eating before exercising or doing other vigorous activity.
Don't brush your teeth right after a meal.
If these tips don't ease your nausea, talk with your healthcare provider.
Children become dehydrated more quickly than adults do. If your child is vomiting, ask your healthcare provider how to help your child feel better.
If you are vomiting, try these tips:
Take a break from solid food, even if you feel like eating.
Stay hydrated by sucking on ice chips or frozen fruit pops. Try drinking sips of water, weak tea, clear soft drinks without carbonation, noncaffeinated sports drinks, or broth. Sugary drinks may calm the stomach better than other liquids.
Temporarily stop taking oral medicines. These can make vomiting worse.
Slowly add bland foods. If you've been able to drink some fluids and haven't thrown up for 6 to 8 hours, try eating small amounts of foods such as bananas, rice, applesauce, unbuttered toast, dry crackers, or dry cereal.
Once you're back on solid food, eat small meals every few hours. This helps your stomach digest food slowly.
Stay away from strong odors, such as tobacco smoke, perfumes, or cooking smells.
Stay away from dairy products, tobacco, and alcohol. They may irritate your stomach.
Get plenty of rest.
Vomiting that is caused by medicines, surgery, or radiation therapy may be treated by taking a different medicine. Medicines are also available to treat vomiting in pregnancy and other conditions. Talk with your healthcare provider about what’s best for you.
