When to Seek Help?

Usually, nausea and vomiting are not serious and are common symptoms that can be managed in adults. But, consult a doctor if:

  • There is associated fever or abdominal cramping or pain.

  • It follows a head injury or fall.

  • If there is a new or recurring episode of a severe headache or a migraine.

  • If you vomit blood, be it fresh (bright red) or old (brown/dark red).

  • You are known to have a medical condition involving the heart, kidney or liver.

  • There is severe fatigue or dehydration.

  • If your neck is stiff.

  • If you are exhibiting mental confusion and rapid pulse.

For a child who is below 6 years of age, seek emergency care if he or she has:

  • Projectile vomiting.

  • Wrinkled skin, reduced consciousness, and a weak pulse, as these are signs of dehydration.

  • Been vomiting for around 2 to 3 hours.

  • Not urinated in the last 6 hours.

  • A fever of above 100°F (38°C).

For a child who is above 6 years of age, seek emergency care if he or she has:

  • Vomited for more than 12 hours.

  • Been showing symptoms of dehydration.

  • Not urinated in the last 6 hours.

  • A fever of 102°F (39°C) or higher.

When Can Vomiting Become Dangerous?

The following situations can be potentially life-threatening.

1) If vomiting is because of severe conditions such as head injury, meningitis, brain tumor, and appendicitis, then it should be taken seriously.

2) Dehydration is the most crucial complication of vomiting, especially in kids. It is rare in adults because the symptoms of dehydration in adults, such as increased thirst and dry mouth, make them drink water. But as kids cannot communicate and identify these symptoms, dehydration can become severe and also fatal. So if your kid’s lips are dry or they become irritable or confused, give them oral fluids immediately. For infants, less urination and a sunken fontanelle, which is the soft spot on the baby's head, can be considered signs of dehydration.

3) Some pregnant women can develop a serious condition called hyperemesis gravidarum, where the woman vomits continuously, which can potentially endanger her and her unborn child’s life.

4) In some rare patients, excessive vomiting can lead to Mallory-Weiss tear, which is a tear in the lining of the esophagus. This is a medical emergency.

How Does a Doctor Diagnose the Cause of Nausea and Vomiting?

Once you seek a doctor's advice, they will find the cause based on your associated symptoms and history. In some cases, a few investigations may be necessary to rule out certain disorders:

  1. Blood tests.

  2. Upper GI (gastrointestinal) endoscopy.

  3. Ultrasound scan.

What Are the Treatment Options for Nausea and Vomiting?

1) Home Remedies:

Nausea and vomiting can be managed at home with these tips:

  1. Ginger is known to help ease the queasy feeling. So, are citric fruits. Include ginger in lemonade if ginger tea is not agreeable to you.

  2. Have bland foods such as crackers, toast, or wheat rusk on an empty stomach to keep nausea at bay.

  3. Avoid hot, greasy, and spicy foods until you get completely alright.

  4. Keep yourself hydrated with fresh juices, yogurt drinks, or green tea. Sip only a little fluid at a time.

  5. Eat what you feel like whenever you are comfortable. Do not force yourself to eat your regular meal on schedule at this point.

  6. Although the symptoms seem to come from the stomach, nausea and vomiting are controlled by the brain. So, relax your mind and distract yourself.

  7. Surround yourself with pleasant sights and smells.

  8. Get ample rest.

  9. Take antiemetics as prescribed by your doctor.
