Stroke Risk Due to Animal Bites

Animal bites are an unusual cause of stroke. In some areas based on geographical and climatic conditions, various toxic creatures can thrive and pose a real threat to the people around them.


Bites of some types of snakes, spiders and scorpions can cause physiological changes in the body resulting in neurological disorders and strokes. Certain types of toxins emitted from animal bites or stings have chemical properties that interfere with blood clotting functions, causing excessive bleeding, stimulating the release of hormones and altering blood vessels that later lead to stroke. A stroke caused by sudden bites and animal stings may be severe because of sudden toxic spikes released into the victim's body.

Snakebite

There are many reports of snake bite cases that result in stroke. A viper snake, which can be found in many locations around the world, has been repeatedly identified as a source of stroke in humans.

The toxins secreted during the bite into the victim's circulation contain a number of toxins that produce complex interactions with the human body. The effects of toxins include excessive bleeding, which triggers hemorrhage in many of the injured organs of the victim's body. Sometimes, the venom of a snake causes opposite effects, affecting blood clots in the brain or other body structures. Other poisonous snakes, like rattlesnakes, put poison into the injured victim system, then cause a combination of bleeding and blood clots throughout the body. Proteins such as metalloproteinases, serine proteases and C-lectins, found in snake venom, have anticoagulant and pro-coagulation activity.

Effective treatments include anti-toxins as well as urgent medical examinations and treatments, including respiration, heart and kidney. Failure ineffective treatment has been reported in cases when there is a delay in identifying reptile and anti-toxic drugs.

Spider Bites

Spider bites are associated with muscle paralysis due to the direct action of neurotoxins on the nerves and muscle transmission. Muscle paralysis can target any of the muscles in the body, including muscles that support vital functions such as breathing and heart contractions. However, spider poison can also cause severe coagulation disorders, resulting in stroke. Blood clots caused by poisonous spider bites can cause strokes in every part of the brain, and can cause more than one stroke at a time. Similar to medical treatment for poisonous snake bites, medical care from patients suffering from strokes due to poisonous spider bites should include rapid treatment and alert for symptoms of stroke coupled with injections of anti-toxic medication.

Scorpion Stings

The sting of several types of scorpions can cause a number of serious life-threatening consequences, including heart rate deviations, muscle paralysis, and respiratory distress. Severe disorders of heart function and blood pressure can trigger one or more hemorrhagic strokes. In addition, scorpion venom can directly interfere with normal processes that regulate bleeding and blood clotting, causing hemorrhagic or ischemic stroke in the brain. The sting of the scorpion induces the excess activity of catecholamines, which are the stimulating hormones. During catecholamine activity can induce a stroke due to extreme changes in blood vessel diameter, cerebral vascular spasms, and abnormal heart rate reactions.

What should I do?

Animal bites can be harmful to the victim. Urgent medical care is always necessary, as life-threatening symptoms can develop rapidly. Indigenous animal species vary depending on the local environment and climate. Systematic medical care is often required to counter the physiological effects of harmful components of toxins. Often, anti-toxic preparations are needed to flick the toxins injected through bites or stings.
