seizure with nausea

Overview

A seizure is a sudden burst of electrical activity in the brain. Nausea (feeling sick to your stomach) can sometimes happen before or during a seizure. For some people, nausea is an early warning sign called an aura. For others, it occurs as part of the seizure itself. This combination is most common in a type of seizure called a focal (or partial) seizure, which starts in one area of the brain.

Seizures are common – about 1 in 100 people will have a seizure at some point in their life. Nausea is a common symptom in certain types of seizures, especially focal aware seizures (where the person remains awake).

Seizures can affect people of any age, from babies to older adults. Focal seizures with nausea are more often seen in people with epilepsy, but can also happen after a head injury, infection, or stroke.

Symptoms

Common symptoms

• Nausea or a rising sensation in the stomach
• Vomiting
• Dizziness or lightheadedness
• Unusual smell or taste
• Feeling of fear or déjà vu
• Staring into space or being unresponsive
• Jerking movements of a limb or one side of the body
• Confusion or feeling 'foggy' after the seizure

Symptoms in children

• Nausea and vomiting without a known cause
• Staring spells or daydreaming that is hard to interrupt
• Complaints of a funny feeling in the tummy
• Sudden fear or crying for no reason
• Loss of bladder control

Symptoms in older adults

• Periods of confusion or disorientation
• Nausea with no other stomach illness
• Memory lapses or blank spells
• Unexplained falls or clumsiness
• Feeling of dizziness or vertigo

Causes

Main causes

• Epilepsy – a condition where the brain is prone to seizures
• Temporal lobe epilepsy (a type of epilepsy that often starts in the temporal lobe)
• Head injury or trauma to the brain
• Brain infections, such as meningitis or encephalitis
• Stroke or brain tumor
• Genetic conditions that affect the brain
• Metabolic problems, like very low blood sugar or sodium levels
• Alcohol or drug withdrawal

Risk factors

• Family history of epilepsy or seizures
• Previous head injury or brain surgery
• Stroke or other blood vessel problems in the brain
• Brain infections in the past
• Developmental disorders, like autism or cerebral palsy
• Sleep deprivation, stress, or missing meals (can trigger seizures in people who are prone)

When to see a doctor

See a doctor urgently if:

• If you or someone else has a seizure for the first time – see a doctor or go to the emergency room
• If the seizure lasts more than 5 minutes or repeats without recovery – call emergency services immediately
• If the seizure causes injury, like a cut or head bump
• If the seizure happens in water or while driving
• If the person is pregnant, has diabetes, or has a serious illness

Book a routine appointment if:

• If you have epilepsy and notice a new symptom, like nausea, that you didn't have before
• If your seizures are happening more often or feel different
• If you are having side effects from seizure medication
• If you have concerns about your seizure treatment plan

Diagnosis

A doctor will take a detailed history of what happens before, during, and after the seizures. They will also ask about your medical history and any family history of seizures. If possible, someone who has seen your seizures should describe what they observed.

Tests that may be done

• EEG (electroencephalogram) – a test that records the brain's electrical activity using small sensors on the scalp
• MRI (magnetic resonance imaging) – a scan that takes detailed pictures of the brain to look for structural causes
• CT scan – another type of brain scan that can quickly show bleeding, tumors, or other abnormalities
• Blood tests – to rule out infections, electrolyte imbalances, or genetic causes

What to expect at your appointment

Your doctor will talk with you about your symptoms and may refer you to a neurologist. The tests are painless, though you may need to stay still. For an EEG, you might be asked to sleep less the night before so the test can pick up activity during drowsiness. You may need to wait for results, but your doctor will discuss the next steps with you.

Treatment

Treatment for seizures with nausea aims to stop or reduce the number of seizures and improve quality of life. The right treatment depends on the cause, seizure type, and your overall health. Most people with epilepsy can control their seizures with medication.

Self-care at home

• Get enough sleep every night – lack of sleep can trigger seizures
• Avoid alcohol, recreational drugs, and heavy caffeine
• Manage stress with relaxation techniques like deep breathing or meditation
• Take your seizure medications exactly as prescribed – never stop suddenly without talking to your doctor
• Keep a seizure diary to identify triggers and track symptoms like nausea

Medical treatments

Doctors usually start treatment with anti-epileptic drugs (AEDs) – a class of medications that help prevent seizures. The type of AED depends on the seizure type and other factors. If one medicine doesn't work well, your doctor may try another or combine two. All medicines have possible side effects, so your doctor will monitor you closely. Other treatment options include the ketogenic diet (a high-fat, low-carbohydrate diet that can help control seizures), vagus nerve stimulation (a device implanted in the chest that sends signals to the brain), and responsive neurostimulation (a device that detects seizure activity and delivers electrical stimulation to stop it).

When is surgery considered?

If seizures are not controlled with medications and a clear seizure focus (the area where seizures start) can be found, surgery may be an option. Surgery to remove the focus, especially in the temporal lobe, can stop or greatly reduce seizures. Your neurologist and a neurosurgeon will discuss if this is right for you.

Living with this condition

Living with seizures that include nausea can be challenging, but many people manage well with treatment. Keep a seizure diary to note when nausea occurs and what you were doing before. Wear a medical ID bracelet or necklace that says you have seizures. Tell your family, friends, and coworkers what to do if you have a seizure: stay calm, time the seizure, protect your head, and call for help if it lasts too long.

Lifestyle tips

• Get regular, consistent sleep
• Eat meals at regular times to avoid low blood sugar
• Stay hydrated, but avoid too much fluid at once
• Limit screens and bright flashing lights if they trigger seizures
• Avoid risky activities like swimming alone or climbing heights

Diet and exercise

A balanced diet rich in fruits, vegetables, and whole grains supports overall health. Some people find that a special diet like the ketogenic diet helps control seizures, but this should only be done under medical supervision. Moderate exercise, like walking or yoga, is good for stress and mood, but avoid overheating or becoming very tired. Always talk to your doctor before starting a new exercise program.

Mental health and emotional wellbeing

Seizures can cause anxiety about when the next one will happen, and nausea can make you feel sick and worried. Depression is common in people with epilepsy. It's important to talk to your doctor if you feel sad, anxious, or afraid. They can connect you with a counselor or support group. You are not alone.

Prevention

Not all seizures can be prevented, especially if they are caused by epilepsy or a brain condition. However, you can reduce the risk of triggering seizures by managing known triggers: getting enough sleep, avoiding alcohol and drugs, managing stress, and taking your medication regularly. If you have a condition like epilepsy, following your treatment plan is the best way to prevent seizures.

Screening programmes

There are no routine screening tests for seizures in people without symptoms. If you have a family history of epilepsy or a condition that increases risk, your doctor may suggest monitoring. Seizures are usually diagnosed after they happen.

Complications

If left untreated

• Increased risk of injury during seizures (falls, burns, drowning)
• Status epilepticus – a prolonged seizure that doesn't stop, which can be life-threatening
• Memory problems and difficulty concentrating
• Mood disorders like depression and anxiety
• Social isolation or difficulty working or driving

Long-term outlook

With proper diagnosis and treatment, most people with seizures can achieve good control and live full, active lives. Many people stop having seizures with medication or other treatments. Even if seizures continue, they may become less frequent and less severe. It's important to work closely with your healthcare team and stay hopeful – you can manage this condition.
