Why do Autoimune conditions include severe incontinence in some cases?

My wife is not getting any satisfactory answers to this question so someone out there please help

It really does depend on the Autoimmune condition.

MS for example is a condition where the insulating sheaths aroung the nerves in the brain and spinal cord break down and get replaced by hard scar tissue.
This affects the conducting ability of the nerve and if it supplies the bowel or bladder the nerve supply to this organ is compromised. because of this the organ doesn't function properly hence you can become incontinent.
A more common symptom of MS is your bladder doesn't release for up to 36 hours!!

If you can be a little more specific about the condition I may be able to give you a more concise answer.

If the bowel is not working properly this is an indication that neither is the immune system.

Recommend visit to the health food shop to get some good quality full strength probiotics in tablet or capsule. Take the full course - if the problem is very bad you may need to see your GP and discover the cause.

Probiotics are especially helpful for irritable bowel and after taking a course of antibiotics.

Have her kidneys been checked? That could be worth a look. I have an auto immune disease which gave me kidney failure and I have issues such as this

Some autoimmune conditions can lead to neuropathy (nerve ending damage). Autonomic neuropathy results in faulty communication with your brain and the affected parts of the body. This can lead to difficulties which range from dizziness to trouble with digestion and urination to sexual difficulties, dependent upon which nerves are affected.

See the following page for a better description of autonomic neuropathy.

Of course, I'm not a medical practitioner, so I might be totally wrong here, but these are some of the ways in which I'm affected. Your best bet is for your wife to see her doctor, and to ask to be referred to a specialist if s/he can't give a definitive opinion.
