T44: Poisoning by drugs primarily affecting the autonomic nervous system
T44.4: Poisoning: Predominantly alpha-adrenoreceptor agonists, not elsewhere classified
Many processes run unconsciously in the body. These include breathing and digestion, for example. The heartbeat or blood pressure are also adjusted independently by the body. These processes are controlled by certain nerves. Nerves transmit information in the body.
You have taken a medication that narrows your blood vessels, for example.
If you have taken too much of the medication, your heart usually beats quickly and your blood pressure is too high. Sometimes you also feel sleepy or lose consciousness. The symptoms depend on how much the body has been damaged by the medication, among other things. Severe illness is also possible.
