Quick Answer
Yes, past snake bites can lead to increased sensitivity or allergies, known as hypersensitivity or anaphylaxis, especially if the venom is not fully cleared from the body.
Understanding the Risk of Hypersensitivity
When a person is bitten by a snake, the body’s immune system responds by producing antibodies to fight the venom. If the venom is not fully cleared from the body, the antibodies can remain and cause an allergic reaction upon future exposure. Studies suggest that the risk of anaphylaxis increases with each successive snake bite, with one study indicating that the risk doubles with each bite.
Diagnosis and Treatment
Diagnosing hypersensitivity to snake venom can be challenging, as symptoms may be similar to those experienced during the original bite. A healthcare professional may perform skin prick tests or blood tests to determine the presence of antibodies. Treatment for anaphylaxis involves administering epinephrine via an EpiPen or other auto-injector, and providing supportive care such as oxygen and monitoring. In severe cases, hospitalization may be necessary.
Prevention and Management
Individuals who have experienced a past snake bite and are at risk of hypersensitivity should carry an EpiPen and wear a medical alert bracelet. They should also inform healthcare providers of their history, as this can help prevent misdiagnosis and ensure prompt treatment in the event of an allergic reaction. If a person is bitten by a snake again, they should seek medical attention immediately and inform their healthcare provider about the location and severity of the bite.
