Histamine intolerance is the overproduction of histamine in the body or the inability to break it down. When histamine levels get too high or when it can’t break down properly, it can affect the normal bodily functions.
Many sypmtoms of a histamine intolerance are similar to common allergic responses and symptoms:
• headaches or migraines
• nasal congestion or sinus issues
• hives
• fatigue
• digestive issues
• vomiting
• nausea
• irregular menstrual cycle
In even more severe cases of histamine intolerance, the following symptoms might occur:
• tissue swelling
• high blood pressure
• abdominal cramping
• anxiety
• irregular heart rate
• dizziness
• difficulty regulating body temperature
