What Happens If You Accidentally Eat A Poisonous Mushroom?

Immediate Symptoms

Nausea and vomiting

If you accidentally eat a poisonous mushroom, one of the immediate symptoms you may experience is nausea and vomiting. Your body may try to expel the harmful substance by inducing vomiting. This can be a distressing experience, but it is your body’s way of protecting itself.

Abdominal pain

Another immediate symptom of mushroom poisoning is abdominal pain. This pain can range from mild discomfort to severe cramping, depending on the severity of the poisoning. The toxins from the mushroom can irritate your digestive system, leading to abdominal discomfort.


Accidental ingestion of a poisonous mushroom can also lead to diarrhea. Your body may try to flush out the harmful substances through increased bowel movements. Diarrhea can be accompanied by abdominal pain and frequent trips to the bathroom.

Excessive sweating

Excessive sweating is an immediate symptom of mushroom poisoning that some individuals may experience. The toxins present in the mushroom can cause your body to produce more sweat as a way to eliminate the harmful substances. This excessive sweating can be uncomfortable and may contribute to feelings of dizziness or weakness.


Dizziness is another immediate symptom that you may experience after accidentally ingesting a poisonous mushroom. The toxins in the mushroom can affect your central nervous system, leading to feelings of lightheadedness or instability. It is important to be cautious and seek medical attention if you feel dizzy after consuming a poisonous mushroom.

Severity of Poisoning

Varies based on the type of mushroom

The severity of mushroom poisoning can vary greatly depending on the type of mushroom ingested. Some poisonous mushrooms cause only mild symptoms that may resolve on their own, while others can be life-threatening. It is crucial to identify the type of mushroom consumed, as certain species are known to be highly toxic.

Inducing vomiting

If you accidentally eat a poisonous mushroom, it is important to seek prompt medical attention. In some cases, the healthcare provider may induce vomiting to help rid your body of the harmful toxins. This can be done by administering a medication or through other means, depending on the situation and severity of poisoning.

Administering activated charcoal

Fluids and electrolyte replacement

To manage the symptoms and complications associated with mushroom poisoning, healthcare providers may administer fluids and electrolyte replacements. This helps ensure hydration and maintain the balance of essential minerals in your body. Fluids may be given orally or intravenously, depending on the severity of the poisoning.

Specific antidote if available

In some cases, there may be specific antidotes available for certain types of mushroom poisoning. These antidotes are designed to counteract the effects of the specific toxins present in the mushrooms. Prompt identification of the mushroom type is crucial to determine if a specific antidote is available and should be administered.

Supportive care

Supportive care is an integral part of the treatment for mushroom poisoning. This involves monitoring vital signs, addressing symptoms, and providing comfort measures. Supportive care also includes close observation of organ function, as damage to the liver, kidneys, and nervous system can occur.


Often necessary for severe cases

In cases of severe mushroom poisoning, hospitalization is often necessary. This allows healthcare professionals to closely monitor your condition and provide appropriate medical interventions. The severity of symptoms, organ damage, and overall health status are important factors in determining the need for hospitalization.

Monitoring of organ function

During hospitalization, healthcare providers will closely monitor the function of your organs, especially the liver and kidneys. Blood tests may be performed to assess liver and kidney function, as well as to detect any abnormalities in the blood composition. Monitoring organ function helps guide the appropriate treatment and management strategies.

Addressing complications

Mushroom poisoning can lead to various complications, such as liver failure, kidney damage, or neurological problems. Hospitalization allows for the timely identification and management of these complications. Prompt intervention can help minimize the long-term damage and enhance the chances of a successful recovery.

Obtaining specialized treatment if required

In cases of severe mushroom poisoning or when complications arise, specialized treatment may be required. This can involve consultation with toxicology experts or other specialists. Specialized treatments may include interventions such as hemodialysis for kidney failure or liver transplantation in cases of severe liver damage.
