Dysautonomia means that your body has trouble doing things that it normally does without you thinking about it, like breathing, swallowing, sweating, and keeping your heart rate steady.
Imagine your body is like a car, and the autonomic nervous system is the driver. Just like a driver controls a car, the autonomic nervous system controls all of the things your body does automatically. But sometimes, the driver can't control the car properly, and the car starts to do weird things like swerve or stall. That's what happens with dysautonomia.
People with dysautonomia might have trouble breathing or swallowing, sweat too much or too little, or have a dry mouth. They might feel dizzy or lightheaded, have a fast or slow heartbeat, or have trouble regulating their blood pressure.
There are many different types of dysautonomia, and they can be caused by different things like genetic disorders, autoimmune diseases, or nerve damage. Treatment depends on the cause, but it might involve medications, lifestyle changes, or physical therapy.
