What Are The Symptoms of Food Poisoning?

Abdominal Pain and Cramps

The bacteria consumed in mushroom poisoning primarily irritate the intestines and can cause an imbalance in your natural, good bacteria.

The situation can cause stomach inflammation,  and lead to severe abdominal pain.

Our abdominal muscles try to expel the bad bacteria through the intestines,which are forced to work faster than normal, and put pressure on our abdominal muscles, causing our muscles to cramp.

Raised Temperature and Headaches

One of the most common symptoms of food poisoning is severe headaches and a rise in temperature as our bodies try to fight the bacteria. 

The headaches occur when the body redirects water resources to help flush out the bacteria, leading to dehydration.

If the body is dehydrated for a long time, this can cause severe headaches. 


If diarrhea is experienced for more than 6 hours, you could have mushroom food poisoning. 

Diarrhea is when your body tries to expel the bacteria from the lower intestine, and a result of the extra water that has been sent there to help the process.

If you experience diarrhea along with other symptoms of mushroom food poisoning, be sure to drink plenty of water.


Vomiting occurs with excessive contraction of the abdominal muscles to rid the stomach of unwanted bacteria or toxins before they reach the intestines.

Vomiting is one of the first symptoms seen in mushroom food poisoning. Unlike diarrhea, vomiting is a defense mechanism, and your body attempts to rid itself of the bacteria before it causes further damage.

If you have fallen victim to severe mushroom food poisoning and your symptoms persist, consult a doctor immediately.
