What causes nausea or vomiting?

  • Nausea is an upset stomach that often occurs before vomiting. Vomiting is the forced emptying of the contents of the stomach through the mouth (“vomiting”).
  • What causes nausea or vomiting?
  • Nausea and vomiting are not diseases, but they are symptoms of many diseases, such as:
  • Motion sickness or seasickness
  • Early stages of pregnancy (nausea occurs in approximately 50%-90% of all pregnancies; vomiting occurs in 25%-55%)
  • Vomiting caused by drugs
  • Severe pain
  • Emotional stress (such as fear)
  • Gallbladder disease
  • Food poisoning
  • Infections (such as “stomach cold”)
  • Overeating
  • Reaction to certain odors or odors
  • heart attack
  • Concussion or brain injury
  • Brain tumor
  • ulcer
  • Certain forms of cancer
  • Bulimia or other mental illness
  • Gastroparesis or slow gastric emptying (this can be seen in diabetic patients)
  • Ingestion of toxins or excessive alcohol
  • intestinal obstruction
  • appendicitis
  • The cause of vomiting varies with age. For children, vomiting is usually caused by viral infections, food poisoning, milk allergy, motion sickness, overeating or eating, coughing or intestinal blockage, and high fever in children.
  • Is vomiting harmful?
  • Normally, vomiting is harmless, but it may indicate a more serious illness. Some examples of serious conditions that can cause nausea or vomiting include concussion, meningitis (infection of the meningeal lining), intestinal obstruction, appendicitis, and brain tumors.
  • Another problem is dehydration. Adults have a lower risk of dehydration because they can usually detect symptoms of dehydration (such as increased thirst and lips or mouth). However, young children are at greater risk of dehydration, especially if they also have diarrhea, because they usually cannot communicate symptoms of dehydration. Adults caring for sick children need to be aware of these obvious signs of dehydration: dry lips and mouth, sunken eyes, shortness of breath or rapid pulse. In infants, attention should also be paid to reduced urination and sunken font door (soft spots above the baby’s head).
  • Repeated vomiting of pregnant women can lead to a serious condition called hyperemesis gravidarum. The mother may have an imbalance of body fluids and minerals, endangering them or the life of their unborn child.
  • Very rare vomiting can tear the lining of the esophagus, also known as Mallory-Weiss tears. If the esophagus ruptures, it is called Boerhaave syndrome, which is a medical emergency.
  • When to call the doctor for nausea and vomiting
  • Call the doctor about nausea and vomiting:
  • Nausea lasts for more than a few days or is it possible to become pregnant
  • If home treatment is ineffective, there is dehydration or a known injury that may cause vomiting (such as head injury or infection)
  • If vomiting persists for more than a day, diarrhea and vomiting lasts for more than 24 hours, or there are signs of dehydration, adults should consult a doctor.
  • If vomiting persists for more than a few hours, diarrhea, signs of dehydration, fever, or the child does not urinate for 4-6 hours, please take an infant or child under 6 years old to the doctor.
  • If vomiting lasts for one day, diarrhea combined with vomiting lasts for more than 24 hours, there are any signs of dehydration, fever exceeds 101 degrees or the child does not have a cold, please take a child over 6 years old to see a doctor. Urinate for six hours.
  • If any of the following vomiting occurs, seek medical attention immediately:
  • There is blood in the vomit (the appearance is bright red or “coffee grounds”)
  • Severe headache or stiff neck
  • Drowsiness, confusion or decreased alertness
  • Severe abdominal pain
  • diarrhea
  • Fast breathing or pulse
  • How is vomiting treated?
  • Vomiting treatment (regardless of age or cause) includes:
  • Gradually drink plenty of clear liquids
  • Avoid solid foods until the vomiting episode has passed
  • If vomiting and diarrhea persist for more than 24 hours, oral rehydration solutions (such as Pedialyte) should be used to prevent and treat dehydration.
  • Pregnant women with morning sickness can eat some biscuits before getting up, or eat high-protein snacks (lean meat or cheese) before going to bed.
  • Vomiting associated with cancer treatment can usually be treated with another medication. There are also prescription and over-the-counter medications that can be used to control vomiting related to pregnancy, motion sickness, and some forms of dizziness. However, please consult your doctor before using these treatments.

How to prevent nausea?

• Eat three small meals throughout the day.

•eat slowly.

• Avoid eating foods that are difficult to digest.

• If you are nauseated by hot or warm food, eat cold or room temperature food.

• After eating your head, raise your head to a height of 2 inches from your feet.

• Try to eat when you feel sick.

How can I prevent vomiting after I feel nauseous?

When you start to feel nauseous, you can prevent vomiting by:

• Drink a small amount of clear, sweet liquids, such as soda or fruit juice (except orange juice and grapefruit juice because they are too sour)

• Rest in a seated or supported lying position; activities may make nausea worse and may cause vomiting.

To prevent nausea and vomiting in children:

• To treat motion sickness in a car, please seat your child so that they face the front windshield (observing the rapid movement of the side window may make nausea worse). In addition, reading or playing video games in the car may cause motion sickness.

•Do not let children eat and play at the same time.
