Nausea and vomiting, although common symptoms, can cause a lot of distress when it is persistent. It is important to find out the cause and treat it accordingly.

When to Seek Expert Advice for Nausea and Vomiting?

Nausea is an unpleasant feeling in the stomach that often precedes vomiting. It may or may not be followed by actual vomiting. Vomiting is the forceful throwing up (expelling out) of contents of the stomach through the mouth.

Both nausea and vomiting are commonly caused by different conditions. Both are not diseases per se but non-specific symptoms of various illnesses or disorders.


Some common causes of nausea and vomiting are:

  • Food poisoning.
  • Alcohol intoxication.
  • Drug side effect.
  • Head injury.
  • Repulsive sights and smells.
  • Travel sickness (especially by car or airplane).
  • Early pregnancy.
  • Chemotherapy.
  • Overeating.
  • Migraine.
  • Liver disorders.
  • Inner ear disturbances.


Here are some signs to watch out for in case of persistent vomiting:

  1. Choking.
  2. Dehydration.
  3. Increased thirst.
  4. Dryness of lips and mouth.
  5. Throat irritation.
  6. Severe tiredness.
  7. Weight loss.
  8. Concentrated urine.

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.

When to Seek Help?

Usually, nausea and vomiting are not serious and are common symptoms which can be managed. 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.


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 endoscopy.
  3. Ultrasound scan.


There are many groups of antiemetics which may be prescribed based on the cause. Some commonly prescribed drugs include:

  • Diphenhydramine.
  • Dimenhydrinate.
  • Metoclopramide.
  • Promethazine.
  • Ondansetron.
  • Domperidone.
  • Doxylamine.
