A condition where the body cannot break down histamine efficiently, leading to a buildup that causes allergy-like symptoms (headaches, hives, digestive issues) often after eating histamine-rich foods like aged cheese, wine, or fermented products.
They are receptor antagonists. They bind to histamine receptors (mainly H1 receptors) on cells, physically blocking histamine from attaching and triggering its inflammatory effects.
Yes. Histamine can be present in foods due to microbial fermentation (e.g., in cheese, sauerkraut, soy sauce, wine) or spoilage (especially in fish, where scombroid poisoning is caused by high histamine levels).
