Diabetes is the probable homeostatic disorder that caused neuropathy.
Explanation:
Neuropathy is a common condition that affects peripheral nerves, responsible for forwarding information from the brain and spinal cord to the rest of the body. Peripheral neuropathy can cause permanent nerve damage and is often a disabling and even fatal problem.
When the damage occurs in several nerves, as it did with Shanna (neuropathy affected her entire leg), it is usually the diabetes behind it. At least half of people with this condition develop some type of neuropathy, as there are several forms of neuropathy caused by diabetes.
Bulimia can leave a person's body in a state of hypoglycemia which evidently leads to fatigue, in addition due to the repetitive emesis episodes, the gums are usually affected causing a dental disorder.
