Why can't you eat fish when you have a wound?

Generally, there is no rule that prohibits eating fish when one has a wound. However, avoiding fish in the presence of a wound may be necessary if the individual is allergic to fish or if the wound is already infected. Specific reasons are analyzed as follows:

1. Fish Allergy

This may occur in individuals with an allergic constitution who are prone to allergies from fish, shrimp, crab, and similar foods. When the skin is wounded, its protective function is reduced. An allergic reaction could impair wound healing, leading to prolonged swelling, pain, and even scar formation.

2. Wound Infection

Poor wound care may lead to inflammatory infection, resulting in symptoms such as exudate, redness, and swelling. During inflammation and infection, the body's resistance and immunity are lowered, making allergic reactions more likely upon exposure to seafood, which can hinder inflammation resolution and delay wound healing.

Fish is a food rich in protein. If there is no allergy to fish and no signs of wound infection, consuming moderate amounts under a doctor’s guidance is generally acceptable and can help provide essential nutrients, supporting recovery and improving overall condition.
