Understanding Nausea and Vomiting: Causes, Symptoms, and Treatment












Self Care

What is Nausea and Vomiting?

Nausea and vomiting are the two very common symptoms that can be associated with various medical conditions. Nausea refers to a sensation of unease or discomfort in the stomach, often accompanied by an urge to vomit. Vomiting, on the other hand, is the act of expelling the food contents of the stomach through the mouth. Nausea typically precedes vomiting and is often described as a feeling of queasiness or an unsettled stomach. Vomiting, on the other hand, is identified as the forceful expulsion of stomach food contents through the mouth. Nausea and vomiting can mostly occur as a result of several factors, including:
  • Gastrointestinal Disorders
  • Motion Sickness
  • Medications and Treatments
  • Pregnancy
  • Infections
  • Psychological Factors
While nausea and vomiting can affect anyone, certain groups of people may be more prone to experiencing these symptoms. For example, individuals undergoing chemotherapy or radiation therapy, those with gastrointestinal disorders, pregnant women, and individuals with a history of motion sickness may be more likely to experience nausea and vomiting.

The signs and the symptoms of nausea and vomiting can vary from person to person and depend on the underlying cause. Here are some of the most important signs and symptoms to be aware of:
  • Nausea: This is the main symptom and is characterized by a feeling of queasiness or discomfort in the stomach. It may be also accompanied by a sensation of unease or a need to vomit.
  • Vomiting: This refers to the act of forcefully expelling the food contents of the stomach through the mouth. It may provide temporary relief from nausea, but it can also be distressing and exhausting.
  • Dry heaves: These are repetitive involuntary movements of the diaphragm and abdominal muscles, similar to vomiting, but without any expulsion of stomach contents. Dry heaves can be accompanied by a retching or gagging sensation.
  • Loss of appetite: Nausea and vomiting can lead to a decreased desire to eat, resulting in a loss of appetite.
  • Dehydration: If vomiting is persistent or severe, it can lead to dehydration. Signs of dehydration include dry mouth, decreased urine output, dark-colored urine, fatigue, and dizziness.
  • Abdominal discomfort: Nausea and vomiting can be accompanied by abdominal pain or discomfort. This can vary in intensity and location depending on the underlying cause.
  • Dizziness or lightheadedness: Nausea and vomiting can cause a sensation of dizziness or lightheadedness, which may be due to dehydration or the body’s response to distressing symptoms.
It’s important to note that while nausea and vomiting are often harmless and resolve on their own, they can also be symptoms of other underlying medical conditions. In some cases, persistent or severe nausea and vomiting may be indicative of more serious issues, such as:
  • Gastrointestinal disorders like appendicitis, gallbladder disease, or pancreatitis
  • Inflammatory bowel disease
  • Kidney or liver problems
  • Thyroid disorders
  • Migraine headaches
  • Inner ear disorders (associated with motion sickness)


What Are Some Reasons for Nausea?

Nausea and vomiting can be often caused by a variety of factors. Some common causes include:
  • Gastrointestinal Disorders: Several conditions affecting the gastrointestinal tract can lead to nausea and vomiting. These include gastroenteritis (stomach flu), gastritis (inflammation of the stomach lining), peptic ulcers, gastroesophageal reflux disease (GERD), and gallbladder disease. These conditions can irritate the digestive system and trigger the symptoms.
  • Infections: Viral or bacterial infections, such as viral gastroenteritis (stomach flu) or food poisoning, can cause nausea and vomiting also as part of their symptoms. These infections often result from consuming contaminated food or water.
  • Motion Sickness: Motion sickness mostly occurs when there is a disconnect between the sensory input received by the brain, such as visual cues and signals from the inner ear. This discrepancy can be triggered by movements during travel, like in cars, airplanes, boats, or amusement park rides. The resulting conflict in sensory information can lead to nausea and vomiting.
  • Medications and Treatments: Certain medications and medical treatments can cause nausea and also vomiting as side effects. These can include chemotherapy drugs used in cancer treatment, opioid painkillers, antibiotics, antidepressants, and medications that affect the central nervous system. Additionally, some medical treatments like radiation therapy can also induce these symptoms.
  • Pregnancy: Nausea and vomiting, commonly referred to as morning sickness, are common during early pregnancy. Although the definite cause is not fully understood, hormonal changes, particularly increased levels of human chorionic gonadotropin (hCG), are believed to play a role.
  • Psychological Factors: Emotional stress, anxiety, and certain psychiatric disorders like generalized anxiety disorder and also panic disorder can contribute to nausea and vomiting. The exact mechanisms linking psychological factors to these symptoms are not well understood but are thought to involve complex interactions between the brain, gut, and nervous system.
  • Other Medical Conditions: Nausea and vomiting can be associated with various medical conditions not directly related to the gastrointestinal tract. These can include migraines, inner ear disorders (such as Meniere’s disease), kidney or liver disease, thyroid disorders, and certain autoimmune conditions.

When diagnosing the cause of nausea and vomiting, a healthcare professional will typically start by conducting a thorough medical history and physical examination. In addition to the medical history, the doctor may perform the following diagnostic procedures:
  • Laboratory tests: Blood tests may be conducted to check for signs of infection, electrolyte imbalances, liver or kidney problems, or other abnormalities that may contribute to nausea and vomiting.
  • Imaging tests: Depending on the suspected cause, the doctor may also order imaging tests such as an abdominal ultrasound, CT scan, or MRI to visualize the gastrointestinal tract, organs, or other structures to identify any abnormalities or potential causes.
  • Endoscopy: In some cases, an endoscopy may be performed to examine the esophagus, stomach, and upper part of the small intestine. This procedure involves inserting a flexible tube with a camera through the mouth to visually inspect the digestive tract and obtain biopsies if necessary.
  • Pregnancy test: If the patient is a woman of reproductive age, a pregnancy test may be performed to rule out or confirm pregnancy as a cause of nausea and vomiting.
  • Allergy or intolerance testing: If food allergies or intolerances are suspected, the doctor may recommend specific tests to identify potential triggers.
  • Psychological evaluation: If psychological factors are suspected to be contributing to nausea and vomiting, a psychological evaluation may be conducted to assess emotional stress, anxiety, or other mental health conditions.
The diagnostic process aims to identify the underlying cause of nausea and vomiting to guide appropriate treatment. It may involve a combination of tests and procedures based on the individual’s symptoms, medical history, and physical examination findings.


What Are the Nausea and Vomiting Treatment Options?

The treatment of nausea and vomiting depends on the definite underlying cause and the severity of the symptoms. Here are some common approaches to managing these symptoms: Medications:
  • Antiemetics: These are medications specifically designed to relieve nausea and vomiting. They work by blocking receptors in the brain and gastrointestinal tract that are responsible for triggering these symptoms. Examples include ondansetron, promethazine, and metoclopramide.
  • Antihistamines: Certain antihistamines, such as dimenhydrinate or meclizine, can be used to alleviate motion sickness-related nausea and vomiting.
  • Proton pump inhibitors (PPIs) or H2 blockers: If the symptoms are caused by gastroesophageal reflux disease (GERD) or stomach ulcers, medications that reduce stomach acid production, such as PPIs (omeprazole, pantoprazole) or H2 blockers (ranitidine, famotidine), may be prescribed.
  • Other medications: In some cases, medications to manage underlying conditions, such as antibiotics for infections, pain medications for migraines, or anti-inflammatory drugs for gastrointestinal disorders, may be necessary to alleviate nausea and vomiting.
Intravenous fluids: If dehydration is a concern due to severe or prolonged vomiting, intravenous fluids may be administered to restore electrolyte balance and hydration. Dietary modifications: Making dietary changes can often help manage nausea and vomiting. It is also recommended to eat small, frequent meals and also avoid foods that are greasy, spicy, or known to trigger symptoms. Bland foods like crackers, rice, and bananas may be better tolerated.
  • Ginger:> Ginger has natural antiemetic properties and can help alleviate nausea. It can be consumed as ginger tea, ginger candies, or taken in supplement form.
Acupressure: Some individuals find relief from nausea and vomiting by applying pressure to specific acupressure points, such as the wrist (P6 or Neiguan point). Wristbands designed for acupressure, known as “sea bands,” are available and can be worn to provide continuous pressure on the wrist. Relaxation techniques and stress management: For individuals whose symptoms are exacerbated by stress or anxiety, relaxation techniques such as some deep breathing exercises, meditation, or yoga may be helpful in managing nausea and vomiting.

What Helps with Nausea and Vomiting?

There are multiple self-care measures that can help relieve nausea and vomiting at home. While these measures may not address the underlying cause, they can provide temporary relief and promote overall well-being. Here are some important tips and self-care methods to consider:
  • Stay hydrated: Sip small amounts of clear fluids such as water, electrolyte-rich drinks, or ginger ale to prevent dehydration. Take frequent, small sips rather than large amounts at once. Avoid sugary or caffeinated beverages, as they can worsen symptoms.
  • Rest and relax: Allow yourself time to rest and recover. Lie down in a very comfortable position and try to relax your body and mind. Stress and anxiety can exacerbate nausea, so finding ways to reduce any stress.

  • Eat small, bland meals: Stick to easily digestible foods such as crackers, toast, plain rice, or bananas. Avoid fatty, greasy, or spicy foods that can trigger or aggravate nausea. Eat small, frequent filling meals throughout the day to prevent an empty stomach, but avoid overeating.
  • Ginger: Ginger has natural antiemetic properties and can help alleviate nausea. Try sipping ginger tea, chewing on ginger candies, or using ginger supplements as directed.
  • Cold compress: Applying a cold compress or ice pack to the back of your neck or forehead can help alleviate nausea and provide a soothing effect. Fresh air: Open windows or step outside for some fresh air, as stuffy environments can sometimes exacerbate nausea. Taking gentle walks outdoors may also provide relief.
  • Acupressure: Applying pressure to the P6 or Neiguan point on your wrist may help alleviate nausea. You can do this by using acupressure wristbands specifically designed for this purpose or by applying gentle pressure with your thumb.
  • Medications: Over-the-counter medications such as antacids or motion sickness medications may help provide temporary relief. However, it’s important to read and follow the instructions carefully and consult with a pharmacist or healthcare professional if you have any concerns or if your symptoms persist.
  • Seek medical attention: While self-care measures can help alleviate mild cases of nausea and vomiting.

What is Good for Nausea and Vomiting?

Preventing nausea and avoiding vomiting can be challenging since they are often symptoms of an underlying condition. However, there are some strategies that may help reduce the frequency or severity of these symptoms:
  • Avoid triggers: Identify and avoid specific triggers that tend to induce nausea. These triggers can vary from person to person but may include certain foods, strong odors, motion, stress, or anxiety. Minimizing exposure to these triggers can help prevent or reduce episodes of nausea.
  • Eat small, frequent meals: Instead of consuming large meals, opt for smaller, more frequent meals throughout the day. Eating smaller portions can help prevent overeating, which can contribute to feelings of nausea. Choose easily digestible, bland foods and avoid heavy or greasy meals.
  • Stay hydrated: Dehydration can worsen nausea, so it’s important to stay hydrated. Sip small amounts of clear fluids such as water, herbal teas, or electrolyte-rich drinks throughout the day. Avoid consuming large amounts of fluids at once, as it may worsen the sensation of fullness and lead to vomiting.
  • Ginger: Ginger has been shown to help alleviate nausea. Consider incorporating ginger into your diet or using ginger supplements under the guidance of a healthcare professional. Ginger tea, ginger candies, or ginger capsules may be helpful in reducing nausea symptoms.
  • Relaxation techniques: Stress and anxiety can trigger or worsen nausea. Practicing relaxation techniques such as deep breathing exercises, meditation, or yoga can help reduce stress levels and promote a sense of calm, potentially alleviating nausea.
  • Medications: In some cases, your healthcare professional may prescribe medications to prevent or manage nausea and vomiting. These may include antiemetic medications, antacids, or medications specific to your underlying condition. Follow your healthcare provider’s instructions and take the prescribed medications as directed.
  • Motion sickness prevention: If you are prone to motion sickness, taking preventive measures can help reduce the likelihood of experiencing nausea and vomiting. Sit in a well-ventilated area, focus on a fixed point in the distance, avoid reading or using screens while in motion, and consider taking over-the-counter motion sickness medications or using acupressure wristbands.
  • Address underlying medical conditions: If your nausea and vomiting are chronic or recurrent, it is important to seek medical attention to identify and address any underlying medical conditions. Treating the root cause may help alleviate or prevent the symptoms.
