Hypoglycemia / low blood sugar
According to Henry W. Wright
Possible spiritual roots
Fear and anxiety together with self-hatred, self-rejection, and guilt.
A profound lack of identity / insecurity and possible performance orientation may be additional elements of the profile.
Wright links persistent fear with an abnormal neurological signal disrupting glucose supply to the brain; he also mentions a possible autoimmune component.
Spiritual response
Recognize fear, anxiety, self-hatred, self-rejection, guilt, insecurity, or performance pressure; take responsibility, repent, renounce identified patterns, and resist them; receive identity and safety in Christ; pray for healing.
