Most people are familiar with the sensation that follows the consumption of something that upsets the stomach or occurs during cancer treatments. Alternatively, it may be an early sign of pregnancy. That distinctive ‘sick to the stomach’ feeling is common and well-known.
Generally, nausea is the uncomfortable sensation felt in the back of the throat or a sense of uneasiness in the stomach. It can be characterised by dizziness, light-headedness, or difficulty swallowing. Although nausea often accompanies the urge to vomit, it doesn’t necessarily lead to vomiting.
Vomiting refers to the forceful expulsion of stomach contents through the mouth. When you vomit, the stomach muscles contract, pushing the contents up through the oesophagus and out of the mouth.
While nausea and vomiting are not considered illnesses in themselves, they are symptoms of various health conditions, such as:
Both children and adults can experience nausea and vomiting. However, individuals undergoing cancer treatments, such as chemotherapy or radiation therapy, are at a higher risk of experiencing these symptoms.
Additionally, pregnant women, particularly during the first trimester, may experience nausea and vomiting, often referred to as ‘morning sickness.’ Studies estimate that 50% to 90% of expectant women experience nausea, while 25% to 55% vomit.
Nausea and vomiting are typically triggered by changes in the immune and central nervous systems. Various factors can contribute to these changes, including:
Although vomiting is generally harmless, it can also indicate more serious conditions, such as:

While effective remedies for nausea can vary from person to person, several home treatments may help manage or relieve the sensation. Some suggestions include:
Treatment options for vomiting include:
Nausea medications can also be effective for addressing vomiting; however, it’s essential to consult your doctor before trying any treatments.
One major concern associated with vomiting is dehydration. Adults are generally less susceptible to dehydration, as they can recognise symptoms such as increased thirst and dry mouth or lips. However, children are more vulnerable, especially when experiencing vomiting and diarrhoea simultaneously. Adults should be vigilant for signs of dehydration in children, including:
For infants, parents should look for reduced urination and a sunken fontanelle (the soft spot on the top of the head).
To help prevent nausea:
Always rest after eating and elevate your head about 12 inches above your feet to ease nausea. For those who feel nauseous in the morning, eating crackers before getting out of bed or having a high-protein snack (like cheese or lean meat) before bedtime might help. Ensure you drink fluids between meals rather than during them, aiming for at least six to eight 8-ounce glasses of water daily to avoid dehydration. Also, try eating when you’re feeling less nauseous.
Sometimes, vomiting can be prevented by consuming small amounts of clear, sugared liquids like soda, ice pops, and fruit juices (excluding orange and grapefruit due to their acidity). Afterward, rest by sitting or lying in a propped position, as any activity could exacerbate nausea and trigger vomiting.
To address motion sickness, ensure your child faces the front of the car if safe to do so, as looking at fast-moving objects through the side windows can worsen nausea.
Lastly, limit snacks and avoid sugary snacks with soda. Encourage your children to take breaks during snack time rather than eating while playing.
If you experience persistent nausea, you might have a condition known as cyclic vomiting syndrome. This disorder is characterised by sudden attacks of intense nausea, vomiting, and fatigue. Consult your healthcare provider if you exhibit signs of this syndrome, such as recurrent bouts of severe nausea accompanied by retching and vomiting.
Nausea and vomiting are never pleasant experiences. Whether due to overindulgence or fighting off an infection, they can be quite distressing. Fortunately, many cases of nausea and vomiting are not severe, and with some rest, a few saltine crackers, and sips of clear fluids, you will likely feel better soon.
