Histamine intolerance is often misunderstood.
Symptoms such as headaches, skin reactions, digestive discomfort, or fatigue may appear unrelated, but they can sometimes be connected through how the body processes histamine.

Looking at the bigger picture can help identify what may be contributing to these responses.
