12 Side Effects Of Mushrooms
According to a study published in the journal Clinical Toxicology, about 8.8% of 8,953 mushroom-exposed patients succumbed to a suspected cyclopeptide-mushroom poisoning. The findings were based on the data collected by the National Poison Data System over a period of 11 years (2008 – 2018). While mortality is the most severe side effect of mushroom consumption, there are other potential adverse effects to watch out for.
1. Tiredness
Some of the individuals may experience fatigue after consuming mushrooms. You may also feel discomfort and unenergetic. This side effect has been common among many people (1). This side effect might make a few individuals, skip them in the daily routine.
2. Stomach Upset
Eva De Angelis, Dietitian Nutritionist, says, “Some mushrooms contain high amounts of simple carbs that are difficult to digest, such as raffinose and mannitol. As these carbs enter the large intestine undigested, they are fermented by our gut microbiota, producing gas, which contributes to digestive problems in some people, particularly those with IBS.”
Some of the mushrooms’ side effects also create stomach problems among many. In some people, diarrhea has been a problem in eating mushrooms (2). The other stomach problems, which one might experience, are vomiting, and cramping.
Another common side effect of eating mushrooms is nausea. It is caused by a chemical named psilocybin, which is present in most mushroom species. Psilocybin has sensory hallucinogenic properties and may also cause users to experience unexplained feelings of euphoria (3)
3. Absentmindedness
An individual might also be in a state of hallucination. Hallucination is the state in which an individual becomes absent-minded. Due to being psychoactive, mushrooms may result in altered perception of reality after consumption (4). These hallucinatory and mind-altering effects can be compared to the effects of psychedelic synthetic drugs like LSD. The individuals experience the trip within twenty minutes of consumption. After half an hour to forty minutes, the effect reaches its peak. Some may also hear sounds louder than normal in their stomach. Some of them also have a transcendental or spiritual experience after consuming it.

Jonas, an Australian fungi blogger, documents a story about eating raw Ramaria (coral mushroom), leading to a severe allergic reaction. He writes, “My skin became covered in tiny blisters and itched and hurt like mad. It did bring on an attack of Shingles as well which made matters worse. It was worse around my glands and warm bits so my armpits, groin, back of the neck and my fingers and toes were worse affected. The blisters continued for about a week then my skin peeled like a snake (i).”
5. Tingling Sensation
|After 20 to 30 minutes of consumption of mushrooms, some people feel happy and excited. Then, along with the feeling of being excited, they also experience a tingling sensation in their whole body (1). People also experience being depressed.

11. Weight Gain
Mushrooms may make one feel hungry after intake. They contain tryptamines (8). These are chemicals that act like amphetamines (an addictive drug) and may stimulate one’s appetite. Mushrooms also contain ergot alkaloids (9). In some animal studies, these substances had caused vasoconstriction (narrowing of the blood vessels) (10). This may eventually lead to elevated blood pressure levels and potential weight gain.
12. Kidney Failure
In general, edible varieties of mushrooms such as button, portobello, and shiitake are not known to have adverse effects on the kidneys when consumed in reasonable amounts as part of a balanced diet.
However, there are certain types of mushrooms, commonly referred to as wild or exotic mushrooms, which can be toxic. Research has shown that there are different types of mushroom poisoning that can lead to acute kidney injury, depending on the duration of exposure (11). For example, the Amanita genus of mushrooms contains species that are highly toxic and can lead to kidney failure as well as other organ damage (12).
A Word Of Caution
Though the mushrooms are rich in iron, zinc and other nutrients, it should be taken in limited quantities in our daily routine. Of the 1, 40,000 species of mushrooms available in the world today, only 10 percent are safe and edible. Some of the poisonous mushrooms are amanita pantherina, entoloma and chlorophyllum molybdites. Don’t wait for symptoms to occur, when you have eaten a poisonous one. It is also important to choose the correct mushrooms and cook them well.
