Well , opposed to what someone wrote here, antibiotics DO have risks also. Most of your immune system is in your GUT. Pill antibiotics destroy it. Its very hard to get it back. Antibiotics have been implicated in adrenal problems also.
Kidney infections can and usually will have life long implications. An older child can suffer with adrenal disease, addisons disease or glomuralonephritis because of damage when young.
There are things to help. Believe it or not, vit C is amazing. Not only is it imperative to the adrenal gland function, but it maintains and grows COLLAGEN- and collagen is used in the formation of TISSUE and skin , soft organs, bone, etc. You need higher doses, like 1000 - 2000 throughout the day not one dose a day, to do any good. Collagen loss can be implicated in those with esophigeal reflux (caused by a faulty flap.)
Alpha Lipoic Acid 'may' also help. I'm not sure but I read a book on this last year from my library, I think it was called 'The Miracle of Apha Lipoic Acid' ...and I remember thinking it may have helped my DD when she was young. Do a search on "ALA helps tissue growth" , "ALA helps collagen ", " ALA for kidney infection" or something of that nature. I do know that ALA can heal some liver disease and liver infection.
Juicing: Raw, real fresh carrot/apple juice is great for healing tissue, gut and is easy on the kidney plus it helps with any constipation. There are a lot of natural easy PROTIENS in carrots- easier for the kidney than meat protiens. In the first stage of juicing, the bladder will respond by an urgency to urinate or a potty accident, while it is freeing of toxins. That is normal.
My daughter is 16, she had a horrid 'misdiagnosed' kidney infection (lasted 10 days before ABX was given) when she was 2 which has lead to adrenal/renal problems now. (the kidneys share the tubules with the adrenals- indeed, the adrenals sit on top of the kidney and can be damaged if blood continues to circulate through them that has bacteria in it) I've spent my life since then doing medical research. Here is what I've come to find out.
She should have had IV antibiotics for that kidney infection,(pyelonephritis) probably at least 2 weeks if not a month. They are better to combat a standing infection and work faster. If they had done that, rather than mess with pills, perhaps she would not have kidney damage today. Anytime kidney infections are present, immediate and 'aggressive' treatment is necessary to stop damage that will show up down the road. MOST doctors don't understand that but some kidney experts do- few and far between. Or perhaps and more likely, most doctors hands are tied by insurance and because it requires a hospital stay for an IV they don't request it/many insurance might not cover it but I would push for it if I were you. Look up "pyelonephritis and iv antibiotic" online.
'Ongoing' bladder infections many times can have a base in low adrenal hormones which cause body PH to be out of balance. Recurrent UTI is seen many times along with a form of constipation. Constipation is caused by dehydration. Dehydration is caused by lack of water intake OR normal water intake but the kidney is unable to keep the body water level correct- salt loss/water loss -due to kidney damage.
Now, here is what they never told me. The dye that they use for those scans -can and does damage kidneys. Also so does ADVIL and other forms of pain relief. Do not trust that a doctor will know this- go online and do some medical research on it and what other things are 'nephrotoxic to kidneys' so that you are armed going forward. I wish you well.
