  An allergy to cheese is usually caused by an intolerance of lactose or an allergy to dairy. People with dairy allergies are sometimes able to eat dairy in small amounts. Consuming too much cheese, though, can set off a number of symptoms, like abdominal pain, diarrhea and flatulence.
  
  

Abdominal Pain

• A person who has an allergy to cheese and consumes cheese can experience severe abdominal pain. The more cheese that is ingested, the more severe the pain is. The pain can be caused by excessive hydrogen release from colonic bacteria, which causes bloating and distension, according to MedicineNet.com.
  
  

Diarrhea

• When a person has an allergy to cheese, the lactose goes through the small intestine and into the colon. From there, any lactose that isn't split by colonic bacteria uses osmosis to draw water into the colon. MedicineNet.com states that the result of this osmosis is diarrhea.
  
  

Flatulence

• Unabsorbed lactose goes into the colon. There is a type of bacterium present in the colon that splits the lactose and uses the remaining glucose and galactose. When the bacteria uses glucose and galactose, it releases hydrogen gas, which is partly released through flatulence, according to MedicineNet.com.
  
  

Other Symptoms

• An allergy to cheese can be generalized as a food allergy. Food allergies can cause symptoms like rashes, asthma, dizziness and itchiness. Food allergy symptoms are more likely to show up if a person exercises after eating the food they are allergic to.
