Both rumpled and Drnee get gold stars.
There is a high probability of pituitary damage following sever head injuries.
The most famous patient with the problem was a member of the "Beachboys" musical group.
Scientific American magazine did an excellent article a while back on the potential effects of a head injury on the endochrine system. Pituitary activity is most likely to be affected.
You also have my sympathies.
As drnee suggested an endochrine specialist should be on the list of "people to visit".
Hi
Welcome to the forum!
In all probability your partner has suffered sever ear and brain injury along with probably upper cervical injury. I hope a detailed MRI of brain, ear and cervical spine was done. Other tests for ear conducted. Since he is losing weight, either he is not eating or there is increased metabolism due to increased thyroid activity or increased pituitary activity. A combined approach of a neurologist and an endocrine specialist will help.
I am really sorry to hear about your partner and am sorry I cannot help beyond this as of now.
Please let me know if there is any thing else and do keep me posted. Take care!
Have them check the pituitary hormones. Sometimes in trauma, the pituitary also gets squished and gets damaged. If the ACTH is low, your partner may now have Addison's disease, secondary source.
He may need steroids in replacement dose and do fine - he just needs testing. Hormones are very overlooked. Likely other hormones are effected too.
