Introduction
Nosebleeds after eating seafood may be due to allergic rhinitis or could be related to "heatiness" (a traditional concept referring to internal heat). Targeted treatments are available. Seafood contains abundant amounts of foreign proteins, which can directly or indirectly activate immune cells and trigger histamine release, leading to allergic reactions. Individuals with an allergic constitution may develop allergic rhinitis after consuming seafood.

Seafood contains abundant amounts of foreign proteins, which can directly or indirectly activate immune cells and trigger histamine release, leading to allergic reactions. Individuals with an allergic constitution may develop allergic rhinitis after consuming seafood, manifesting symptoms such as sneezing and runny nose. Frequent nose-blowing or wiping can cause local mucosal tears in the nasal cavity, resulting in nosebleeds. In such cases, patients can usually take antihistamine medications under a doctor's guidance, such as loratadine tablets or cetirizine hydrochloride tablets. Additionally, overconsumption of seafood may lead to excessive warming effects in the body, causing "heatiness." This internal heat can increase the fragility of blood vessels in the nasal mucosa and also result in nosebleeds. Patients may follow medical advice to rinse the nasal cavity with saline solution to keep the nasal mucosa moist.
It is recommended that individuals maintain a balanced diet, moderately consume nourishing foods without overindulgence, and avoid seafood entirely if they have a known allergy to it.
