Spring symptoms are not always as simple as “seasonal allergies.”
If this time of year leaves you feeling congested, foggy, anxious, exhausted, itchy, dizzy, overstimulated, or suddenly reactive to foods you usually tolerate, histamine may be part of the picture.
Histamine intolerance can show up through headaches or migraines, flushing, sleep disruption, digestive issues, nausea, skin irritation, brain fog, fatigue, or reactions to wine, leftovers, aged foods, and fermented foods.
Because these symptoms can shift from day to day and affect different systems in the body, histamine issues are often overlooked.
