All the risks below are possibilities of the listed activity. They are listed in no particular order. Please do not consider it to be exhaustive or use it as your sole determining factor when it comes to your safety. Some risk possibilities must nearly always be considered; a few of these can be found here. Additionally, please note that the list below does not account for acts of intentional malice or for every complicating medical condition.
Possible mitigation strategies or more information sometimes appear under risks when given. These should not be considered solutions that bring a risk to 0%, nor should they be considered the only possible solutions or information. Likewise, lack of a mitigation strategy or research being listed does not mean none exists.
Bruising/bursting of capillaries in face (petechiae) – likely/common
Possible lack of ability to determine when receiver loses consciousness—not everyone’s eyes close
Headaches
Drowsiness
Shock
"Fluid balance has great influence on your blood volume, i.e. how much space your blood takes up. Dehydration can cause a shortage of blood in the circulatory system and thereby cause increased risk of hypovolemic shock."
Hypersensitive carotid sinus syndrome
Vomit + breathplay can end in vomit in lungs (aspiration).
Risk increases with drug/alcohol use and fuller stomachs.
Damage to larynx and voice
Seizures
Decreased oxygen levels can cause abnormal heartbeat which in rare cases can lead to cardiac arrest -- a particular risk of smothering incl. with plastic bags
Stroke
Systemic organ failure
"The patient presented initially with cerebral irritability and florid, noncardiogenic pulmonary oedema which were followed by a prolonged period of the adult respiratory distress syndrome, severe sepsis and multiple system organ failure, although the patient eventually survived. The pulmonary injury following strangulation is proposed to be a result of the generation of marked subatmospheric pressures within the lungs during vigorous inspiration against an obstructed airway, although the processes involved in the so-called neurogenic pulmonary oedema are difficult to exclude." -- a medical description of one patient's symptoms after strangulation
