Vomiting is usually caused by a viral infection of the stomach or mild food poisoning. While vomiting is typically not a cause for concern, it can sometimes indicate a more serious condition. If vomiting persists for an extended period, it can lead to severe dehydration or low electrolyte levels, which may require hospitalisation. The threshold for dehydration varies from person to person, and some individuals may require medical attention sooner than others. Therefore, it is essential to monitor other symptoms and seek medical advice if vomiting persists or is accompanied by concerning symptoms.

Dehydration
Vomiting can lead to dehydration, especially if it persists for several days. Prolonged vomiting can deplete the body's fluid levels and electrolytes, resulting in dehydration. The risk of dehydration from vomiting is higher in certain individuals, such as older adults with other medical conditions or young children who may not adequately communicate their thirst.
The symptoms of dehydration can vary depending on its severity. Mild dehydration can often be treated by increasing fluid intake, especially with drinks containing electrolytes. However, moderate dehydration may require medical intervention, such as intravenous (IV) fluid administration in a hospital setting.
Severe dehydration is a life-threatening emergency that requires immediate medical attention. It can lead to disorientation, dehydration headaches, nausea, and vomiting. Additional symptoms of severe dehydration include loss of consciousness, changes in alertness, fever over 102°F (38.8°C), and symptoms of heatstroke, such as rapid pulse or breathing. If you or someone you know is experiencing severe dehydration, it is crucial to seek urgent medical care by calling emergency services or visiting a hospital emergency room.
In summary, dehydration resulting from vomiting or other causes can have varying degrees of severity. While mild cases can be managed by increasing fluid intake, moderate to severe dehydration may require medical intervention, especially in vulnerable individuals like young children or older adults. It is always advisable to prioritize caution and seek medical advice or treatment if you are concerned about dehydration or if symptoms persist or worsen.

Bile in vomit
Bile is a digestive fluid produced by the liver and stored in the gallbladder. It is essential for digesting fats and for eliminating worn-out red blood cells and certain toxins from the body. When someone has thrown up several times, there may not be anything left in their stomach other than bile, which is often greenish in colour. This is usually harmless, but it can also be a sign of a blockage in the intestines, which is a medical emergency. If you are vomiting bile due to bile reflux, you may also experience other symptoms such as upper abdominal pain, frequent heartburn, unintended weight loss, and a persistent cough or hoarseness. Bile reflux can occur due to peptic ulcers or after certain types of surgery, such as a gastric bypass or gallbladder removal.
If you are vomiting bile, it is important to determine the cause. In some cases, vomiting bile can be harmless, such as when it occurs after a night of drinking or a bout of food poisoning. In these cases, the symptom should go away on its own, and you can avoid it happening again by reducing your alcohol intake or avoiding contaminated foods. However, if you are vomiting bile due to a blockage in the intestines, this can quickly become serious and lead to complications such as sepsis or tissue death. Intestinal blockages require urgent medical attention. Bile reflux can also be a symptom of colorectal cancer, which requires immediate medical attention and treatment.
If you are vomiting bile and experiencing any of the following symptoms, you should seek emergency medical care:
- Signs of dehydration
- Abdominal pain
- Fever
- Your first episode of vomiting is green
- Any other concerning symptoms
If you are persistently vomiting bile, it is important to see a doctor to determine the underlying cause and receive proper treatment.

Underlying conditions
While vomiting is usually harmless, it can sometimes be a symptom of a more serious underlying condition. It is a reflex that helps your body get rid of harmful substances. The most common cause of acute (short-term) vomiting is viral gastroenteritis (stomach flu). This is especially common in babies and children, who often experience vomiting and diarrhoea due to infections.
In adults, poisoning is a common cause of vomiting and hospital admission. Common household medicines are the leading cause of poisoning. In addition, viral infections, food poisoning, and motion sickness can cause vomiting.
Other causes of vomiting include:
- Intense pain
- Indigestion
- Migraines
- Overindulgence of alcohol or marijuana
- Medication side effects, such as chemotherapy
- Early pregnancy
- Serious conditions such as concussions, encephalitis, meningitis, intestinal blockage, appendicitis, or brain tumours
If you are experiencing any of these conditions alongside vomiting, it is important to seek medical attention. While vomiting is often harmless, it can sometimes be a sign of a dangerous medical condition. If it persists for several days, it can lead to severe dehydration or low electrolyte levels, which can be life-threatening. Therefore, it is always better to err on the side of caution and seek medical advice if you are concerned about vomiting.

Vomiting blood
Vomiting is usually not a cause for concern and often passes relatively quickly. However, it can sometimes be a symptom of a more serious condition and may even lead to severe dehydration or low electrolyte levels. If you are vomiting blood, this is a medical emergency and you should seek immediate medical attention.
There are several conditions that can cause vomiting blood, ranging from minor to major causes. Minor causes may include swallowing blood from a recent nosebleed, mouth injury, or oral surgery. These situations are unlikely to cause long-term harm. However, more serious conditions such as bleeding ulcers, acute inflammation, enlarged blood vessels that rupture, chronic pancreatitis, traumatic injury, Mallory-Weiss syndrome, tumors, and angiodysplasias can also lead to vomiting blood. These conditions may be life-threatening and require immediate medical attention.
If you are vomiting blood, your healthcare team will first assess your condition and provide immediate support, such as IV fluids, blood transfusions, and oxygen support if necessary. They will then investigate the cause of your condition by asking about your symptoms, medication history, and whether you have any other symptoms. They may perform an upper endoscopy or use other methods to locate the source of the bleeding and ensure it has stopped. It is important to provide as much information as possible to help with the diagnosis and treatment.

Nausea and dizziness
There are many causes of nausea and dizziness. Drugs and alcohol, vertigo, dehydration, and motion sickness are some of the most common causes. In addition, a stomach virus or bacterial infection can cause nausea and vomiting. Norovirus is one of the most common stomach infections, causing vomiting and nausea that can last for a day or longer, sometimes accompanied by a fever, headache, or muscle pain. Bacterial infections may also cause stomach illnesses, such as salmonella and Escherichia coli.
Some people become dizzy when they are dehydrated, so drinking enough water may help prevent dizziness. Dizziness can also be caused by neurological disorders, cardiovascular issues, and inner ear infections. Inner ear infections can interfere with the messages your inner ear sends to your brain. Other inner ear disorders that can cause dizziness include labyrinthitis and vestibular neuritis.
If you are unsure why you are experiencing nausea and dizziness, or if your symptoms are getting progressively worse, you should see a doctor who can diagnose the problem.
