Nerves also control automatic body functions like digestion, sweating, bladder control, and sexual function. Damage to autonomic nerves can cause problems such as:
Feeling lightheaded or faint when standing up (due to blood pressure changes)
Excessive sweating or no sweating at all
Digestive issues like bloating, constipation, or difficulty swallowing
Bladder problems like leaking urine or difficulty emptying the bladder
Sexual dysfunction, such as erectile problems in men or vaginal dryness in women.
