Magic mushrooms and stomach problems

Hallucinogenic mushrooms, also known as psilocybin mushrooms, have been used by various cultures for centuries for ceremonial, therapeutic, and spiritual purposes. However, if you already know this type of mushrooms you will know that one of the common concerns associated with their consumption is the possibility of experiencing stomach problems, such as abdominal pain, nausea, or vomiting.

Today we are going to address this question, studying what are the reasons behind these gastrointestinal symptoms, exploring the factors that contribute to their occurrence, and providing guidelines to minimize their impact during the experience with this type of mushroom, so fashionable today thanks to the growing trend of psilocybin microdosing and therapies associated with this substance.

Effects of hallucinogenic mushrooms

As you may already know, psilocybin mushrooms can have several negative effects on those who consume them, especially if abused or ingested in the wrong environment. However, some of these symptoms appear due to the nature of the fungi and not their psychoactivity, such as stomach pain, nausea, or vomiting. Some of the negative symptoms that may be experienced include:

  • Anxiety and paranoia: Taking hallucinogenic mushrooms can trigger feelings of anxiety, nervousness, and paranoia in some people, especially if they are in an unfamiliar or unsafe environment. The so-called Set & Setting is of great importance, especially for users with little experience.
  • Confusion and disorientation: People who take magic mushrooms may experience mental confusion, spatial disorientation, and difficulty concentrating or processing information coherently.
  • Panic attacks: In rare cases, consumption of these mushrooms can trigger panic attacks or intense anxiety attacks, especially in people prone to anxiety disorders or other mental health problems. Starting with low doses can help save you from this unpleasant experience.
  • Psychotic reactions: In susceptible people, the consumption of hallucinogenic mushrooms can trigger temporary psychotic episodes, characterized by delusions, intense hallucinations, and loss of contact with reality.
  • Nausea and upset stomach: Some people may experience nausea, vomiting, and upset stomach after consuming magic mushrooms, especially if they have gastrointestinal sensitivity or if the mushrooms have not been prepared properly.

As we always remember, it is important to keep in mind that the negative effects of magic mushrooms can vary significantly from one person to another and depend on factors as varied as the dose consumed, the environment, the mood, and the mental health of the individual. Furthermore, the consumption of magic mushrooms should be done responsibly and consciously, ideally under the supervision of experienced people and in a safe and comfortable environment. Preparing everything properly will help you have a full and enriching experience, without problems that could ruin it.

Stomach problems and consumption of hallucinogenic mushrooms

As you've seen - and may have experienced on occasion - these mushrooms can cause stomach problems, nausea, or vomiting. However...Why do these problems occur? Does it have to do with the psychoactive effect or could there be other reasons? Here are some of them:

  • Fiber and chitin content: Mushrooms contain a significant amount of fiber and chitin, which can be difficult for some people to digest. Consuming large amounts of these substances can irritate the lining of the stomach and intestines, leading to stomach upset, nausea, or vomiting. More or less continuous use (microdoses) can also cause this type of discomfort.
  • Psychological effects: Consuming psilocybin mushrooms can have intense psychological effects, such as anxiety or nervousness, especially in people who are not familiar with the effects of psilocin. These mental states can increase feelings of upset stomach and trigger nausea or vomiting as the body's response to emotional stress. Something similar happens to some people when facing certain exams or tests!
  • Improper preparation: If mushrooms have not been properly prepared before consumption, they may contain dirt, bacteria, or other contaminants that can irritate the gastrointestinal tract and cause upset stomach or digestive problems. Always make sure that the mushrooms you are going to consume do not contain traces of soil or other growing media.
  • Individual sensitivity: Some people may be more sensitive than others to the gastrointestinal effects of magic mushrooms. Factors such as gastrointestinal sensitivity, previous diet, general health, and genetic predisposition can influence the likelihood of experiencing stomach discomfort after consuming magic mushrooms.

As you can see, side effects such as stomach pain, nausea, or vomiting after consuming mushrooms can be the result of the interaction of several factors, from the chemical composition of the mushrooms to the psychological effects of consumption and the individual sensitivity of each consumer. An excellent option for consuming your psilocybin mushrooms if you tend to experience these types of problems is a method called Lemon Tek:

Today we present you with a paradigm shift in the way that magic mushrooms are consumed. Thanks to mixing lemon juice with Psilocybin, an easy and quick formula has been found to consume these mushrooms, in addition to generating a different experience from the ones you've had so far.

Chitin and magic mushrooms

Chitin is a polysaccharide found in the cell walls of fungi, insects, and other organisms, such as shellfish. While it is a natural component in many forms of life and is commonly found in the human diet, excessive consumption of chitin can have some adverse effects on the body, something that can occur when consuming magic mushrooms. Some problems that can arise from ingesting too much chitin include:

  • Gastrointestinal irritation: Chitin is difficult for the human body to digest, and excessive consumption can irritate the gastrointestinal tract, resulting in stomach upset, gas, bloating, diarrhea, or constipation.
  • Intestinal obstruction: In extreme cases, excessive consumption of chitin can contribute to the formation of a solid mass in the intestine, known as a chitin bezoar, which can obstruct the passage of food through the gastrointestinal tract.
  • Allergic reactions: Some people may be allergic to chitin, which can trigger symptoms such as itching, rashes, difficulty breathing, swelling of the face, lips, or tongue, and in severe cases, anaphylaxis.
  • Interference with nutrient absorption: Excessive consumption of chitin can interfere with the absorption of certain nutrients in the gastrointestinal tract, such as minerals and vitamins, which could affect the body's overall health and proper functioning in the long term.

In general, while chitin in moderate amounts is safe for most people, excessive consumption can cause gastrointestinal health problems and other adverse effects, something you should keep in mind if you want to consume this type of mushroom. Any nutritionist will tell you that it is important to maintain a balance in your diet and consume foods rich in chitin, such as seafood and mushrooms, but always in moderation.

Thus, the "extra" consumption of hallucinogenic mushrooms (even more so if they are taken raw) can cause problems if you already have a diet rich in chitin. If you experience adverse symptoms after consuming foods that contain it, it will always be advisable to consult a health professional for appropriate guidance and treatment. You can also try other varieties or ways of preparing magic mushrooms to see if you feel better consuming them in another way.
