Sweetheart I'm sorry- I know it is difficult to see your loved one ill. You know what's amazing about doctors? They will do invasive radiactive tests like Cats/Mri's/bone scans, etc, but won't do simple blood tests!!!!
I have a sick daughter and that is what they did to her. I am making them do blood work now. The key to getting your way with the doctors is you need to get informed. that means lots of reading about all the possiblities of what is going on. Go to Wrongdiagnosis.com and type in 'failure to thrive'. There will be a very LONG list- but you will need to go through them, and understand what each one is, so you can help pinpoint the problem. doctors are so fruggn useless.
Have they done testing for heavy metal toxicity?
Have they done testing for parasites?
have they done blood panels on his minerals: calcium, potassium, sodium, iron, etc?
Is he being treated for GERD or any reflux? these meds will cause nutritional discrepanies, failure to grow. h pylori, a stomach bacteria, can cause Gerd
Are they giving him supplements? Iron is a heavy metal that can cause disease. Bacteria MUST have iron /folic acid to feed/reproduce- No one should be giving Iron unless he has had an iron test showing clear deficiency.
Has he been tested for celiacs? it can cause failure to thrive/grow. Also Asthma. Gluten intolerance can come from a fungal or bacterial infection. Celiacs has the same protien chain as candida fungus.
Bacterial infection is listed on my medical notes for failure to thrive.
Also on my failure to thrive notes: (have them do these tests!)
L cartinine deficiency.
Fumerase deficiency
Cobalamin deficiency- (phsycomotor regression after 6th month, to severe hypotonia by 12th month)
choline deficiency
Mangesium deficiency
zinc deficiency
These are listed under floppy baby: (arms flop back when you pick him up, head floppy, etc)
hypothyroidism
Gullian barr infection,
Meningitis
poliomyelitis
vaccines
b12 deficiency
botulism ( should be suspected in any child under 6 months that has weak feeding with a poor cry)
Raw virgin Coconut oil is needed. give- 1 tea 3 x a day in the mouth.
It kills fungal colonies, supports the thyroid, is rich in medium chain triglycerides.
Mangesium is highly recommended for cases of Asthma. You can get babycalm online. If that gives him loose stool, give a smaller dose, or do magnesium oil on the skin- which will soak in transdermally.
