Vomiting After A Stroke: What You Need To Know

Vomiting is a common symptom of a stroke, with 14.5% of stroke patients experiencing it. It can occur during or after a stroke, and it may indicate the onset of another stroke. Persistent vomiting after a stroke should be treated as a medical emergency as it can lead to dehydration and malnutrition, causing further health complications. It is important to seek timely medical attention and work with a skilled medical team to determine the underlying cause of vomiting after a stroke, as there can be various causes, including cyclic vomiting syndrome, side effects from medication, onset of another stroke, or damage to certain areas of the brain.

Nausea and vomiting can be signs of an oncoming stroke

Nausea and vomiting: signs of an oncoming stroke

Nausea and vomiting are symptoms that can occur during a stroke, as well as in the aftermath. While occasional vomiting after a stroke may be a concern, persistent vomiting should be treated as a medical emergency. This is because the body can become rapidly depleted of vital fluids and nutrients, leading to dehydration and malnutrition.

Causes of vomiting after a stroke

There are several reasons why someone might experience nausea and vomiting after a stroke. Firstly, certain types of strokes, such as cerebellar strokes, can cause disruption to the vestibular system, which regulates balance and coordination. This disruption can result in nausea, vomiting, poor balance, dizziness, and impaired gait.

Secondly, changes in brain chemicals and hormones after a stroke can lead to an increase in nausea. The miscommunication between the brain and gut, as well as hormone fluctuations, can contribute to this.

Thirdly, medications used to treat post-stroke symptoms can sometimes cause nausea and vomiting, especially when taken on an empty stomach. It is important to note that not all medications will have the same side effects, and it is always recommended to consult a doctor before making any changes to your medication.

Additionally, cyclic vomiting syndrome, which is characterised by recurrent episodes of vomiting followed by symptom-free periods, may be a result of dysfunction in the gut-brain connection.

In some cases, vomiting after a stroke may be a sign of the onset of another stroke. This is more commonly seen with hemorrhagic strokes, but can occur with other types as well. Therefore, it is crucial to be vigilant for other stroke warning signs, such as slurred speech or weakness in one side of the body, and seek immediate medical attention if a stroke is suspected.

Treating post-stroke nausea and vomiting

The treatment for post-stroke nausea and vomiting will depend on the underlying cause. In some cases, medications such as antiemetics may be prescribed to prevent and treat nausea and vomiting. Other medications that may be prescribed include Zofran, Metoclopramide, and Prochlorperazine.

Dietary changes may also help alleviate symptoms. Consuming less acidic foods and adopting a healthy diet with whole foods and nutrients can be beneficial. Intravenous fluids and electrolyte replacement solutions, such as Pedialyte or coconut water, can also help with dehydration and excessive vomiting.

For those experiencing balance issues in addition to nausea and vomiting, vestibular rehabilitation may be recommended. This type of rehabilitation involves exercises designed to retrain the brain and body to regulate the sense of equilibrium, which can help reduce feelings of nausea and vomiting.

In summary, nausea and vomiting can be signs of an oncoming stroke, and it is important to be vigilant for other stroke warning signs. If you or someone you know is experiencing these symptoms, seek immediate medical attention as it could be a medical emergency.

Persistent vomiting after a stroke can be a medical emergency

Persistent vomiting after a stroke can be a cause for concern and should be treated as a medical emergency. This is because the body can be rapidly depleted of vital fluids and nutrients, leading to dehydration and malnutrition. Therefore, it is essential to seek timely medical attention to prevent a decline in health.

Causes of vomiting after a stroke

There are various causes of vomiting after a stroke, and understanding these causes is critical for recovery. Here are some of the possible reasons:

• Cyclic vomiting syndrome: This condition is characterised by recurrent episodes of stereotyped vomiting separated by symptom-free periods. It is believed to be caused by a dysfunction in the gut-brain connection.
• Side effects from medication: Certain medications can induce vomiting in some individuals. It is important to check the side effects on medication labels and consult a doctor before making any changes.
• Onset of another stroke: Vomiting can be an early warning sign of another stroke. It is crucial to watch for other stroke symptoms such as slurred speech or weakness in the arms or legs.
• Damage to certain areas of the brain: Strokes that affect specific regions of the brain, such as the cerebellum or the vestibular system, can lead to nausea and vomiting, along with balance issues and dizziness.
• Ictal vomiting: Although rare, seizures can sometimes manifest as vomiting. The likelihood of seizures increases after a stroke, so vomiting may signal seizure activity.
• Vestibular disorders: When the vestibular system is impacted by a stroke, it can cause a range of issues, including poor balance, dizziness, and nausea, which may lead to vomiting.

Treating vomiting after a stroke

The treatment for vomiting after a stroke depends on the underlying cause. Hospitalisation is often required for persistent vomiting to replenish fluids and provide essential nutrients. Medical professionals may perform tests to diagnose any underlying conditions and prescribe appropriate treatments. Some treatment options include:

• Medications: Depending on the cause, certain medications may help relieve vomiting symptoms. For example, tricyclic antidepressants can improve cyclic vomiting syndrome, and anti-seizure medications can address ictal vomiting.
• Adjusting problematic medications: If vomiting is a side effect of a particular medication, it may be possible to substitute it for a similar, more tolerable alternative.
• Vestibular rehabilitation: If nausea and vomiting are accompanied by balance issues, vestibular rehabilitation exercises can help retrain the brain and body to regulate the sense of equilibrium, reducing nausea and vomiting.
• Alternative remedies: While there is limited evidence for their effectiveness, some alternative treatments such as acupuncture and herbal supplements may help relieve vomiting when used in conjunction with conventional treatments.

Vomiting after a stroke may indicate the onset of another stroke

Vomiting is a common symptom of strokes, with around 14.5% of stroke survivors experiencing it at the onset. While less frequent, vomiting can also occur after a stroke. This can be a result of damage to certain areas of the brain, side effects from medication, or the onset of another stroke.

Causes of vomiting after a stroke

There are several potential causes of vomiting after a stroke, and it is important to determine the specific cause to inform the recommended treatment. Some possible causes include:

• Cyclic vomiting syndrome: This condition is characterised by recurrent episodes of vomiting separated by symptom-free periods. It is thought to be caused by a dysfunction in the gut-brain connection.
• Side effects from medication: Certain medications can cause vomiting, especially when taken on an empty stomach.
• Onset of another stroke: While not very common, continuous vomiting can be a warning sign of another stroke.
• Damage to certain areas of the brain: Strokes that affect the vestibular system, such as cerebellar strokes, can cause nausea and vomiting, as well as poor balance, dizziness, and impaired gait.
• Ictal vomiting: Although rare, seizures can sometimes manifest as vomiting. As the likelihood of seizures increases after a stroke, vomiting may signal seizure activity.

Treating vomiting after a stroke

Treating vomiting after a stroke depends on its cause. Hospitalisation is often required for persistent vomiting to replenish fluids and provide essential nutrients. In addition, medications such as antiemetics, Zofran, Metoclopramide, and Prochlorperazine can be prescribed to relieve nausea and vomiting.

It is also important to address any underlying medical conditions that may be contributing to post-stroke nausea and vomiting. This may involve controlling conditions such as diabetes, high cholesterol, or high blood pressure, as well as making lifestyle changes such as improving your diet and increasing exercise.

Cyclic vomiting syndrome may be the cause of post-stroke vomiting

Cyclic Vomiting Syndrome (CVS) is characterised by recurrent episodes of vomiting with no apparent cause, separated by regular symptom-free periods. It is a difficult syndrome to diagnose because vomiting is a symptom of many disorders. CVS occurs in all age groups but often begins in children between the ages of 3 and 7.

In a case study, a 69-year-old woman experienced recurrent vomiting following a left cerebral infarct. Her vomiting pattern was consistent with CVS, and the diagnosis was established by excluding other known disorders that could have resulted in vomiting. The patient was treated with imipramine hydrochloride, and her symptoms were well-controlled.

The current theory is that CVS is a functional brain-gut disorder involving central neuroendocrine and peripheral gastrointestinal mediation. The anatomical structures responsible for vomiting are neurons within the hypothalamus, the pituitary gland, and the brainstem. If there are organic problems related to these structures, such as hydrocephalus, brain tumours, or Budd-Chiari malformation, CVS is typically excluded from the diagnosis.

The treatment for CVS is based on its different phases. The best treatment is to prevent CVS episodes during the inter-episodic phases. A tricyclic antidepressant that decreases cholinergic neurotransmission in the medulla is widely used in this phase. This medication can modify the brain-gut axis and autonomic dysfunction, a possible mechanism for CVS.

Vestibular disorders can cause vomiting after a stroke

Vestibular disorders can be classified as Peripheral Vestibular Disorders (PVD) or Central Vestibular Disorders (CVD). PVDs affect the inner ear or the vestibular nerve that carries balance signals to the brain. On the other hand, CVDs impact parts of the brain that process balance signals from the peripheral vestibular system.

Benign paroxysmal positional vertigo, Ménière’s disease, vestibular neuritis, autoimmune inner ear disease, and vestibular migraines are some of the most common vestibular disorders. The causes of these disorders include aging, head injuries, exposure to toxins, inflammation, problems with inner ear fluid, and tumors, among others.

Vestibular rehabilitation therapy, medications, and lifestyle changes are often used to treat vestibular disorders. It is important to seek medical attention if you experience persistent vomiting after a stroke, as it could lead to dehydration and malnutrition, causing a rapid decline in health.
