Yeast in dogs
YEAST WEEK: POST 4/5 THE ROLE OF YEAST IN WEIRD KIDNEY ISSUES...
An undiagnosed internal yeast infection can cause other issues for the patient beyond gut dysbiosis, compromised gut lining, food intolerances and skin issues. It can also induce kidney disease. Here's how it works:
Yesterday we showed you how an internal yeast bloom in the gut lining causes havoc in the gut, leading to degradation of the gut lining resulting in IBD-type diagnoses and food intolerances via "leaky gut".
This is why we advise in such patients, if diet (investigating for food intolerances) with pre/probiotic therapy isn't working for such patients, the very next place to focus on is yeast.
It's well known that 80% of your immune system is around your gut. This is why chronic gut issues cause such large amounts of inflammation - you are kicking the bee hive.
Systemic inflammation increases the amount of circulating immune mediators and metabolic waste, which the kidneys must filter and regulate.
Think of them like a 6 lane highway - the kidneys can take a lot of traffic, God knows, but sometimes, particularly if already under stress, adding more traffic can change things from 3pm normal flowing traffic to 5 o'clock rush hour. Now they start to struggle and it shows up in their blood readings.
Often when you relieve the pressure (in this case by putting the yeast bloom back in the box with Yeast Defeat), the inflammation drops and the kidneys resume normal function.
However, there is a second, often missed issue, and that is the leaky gut that yeast causes doesn't just let undigested food particles through the gut lining barrier, driving intolerances. Sometimes, in very compromised patients, some of the yeast cells themselves can escape in. Now they have access to the blood-rich capillaries beneath. Like wet wipes down the loo, their inevitable destination is the body's filtering system, the kidneys.
Studies show mice with Candida infections developed progressive sepsis and renal insufficiency, with kidney fungal burden correlating with the severity of renal failure.
Termed Candidemia, human and rodent studies show us that levels of various inflammatory cytokines (IL-1β, IL-6, TNF, MCP-1, KC, G-CSF, MIP-2) are shown to rise in the kidneys of such patients, resulting in kidney lesions.
While quick there are quick home tests that can quickly tell you if there's an active problem in the gut / gut lining, vets often miss the fact the kidneys are not just dealing with gut inflammation but yeast running amok internally.
So if you have a pet with strange / unexplained / idiopathic kidney disease, and you can't seem to get this right, particularly if they have a gut dysbiosis (shown by a stool check), consider the fact it might be yeast driving that dysbiosis and thus kidney disease.
Yeast Defeat is not only safe to use in such dogs but by putting in the remedy (instead of going down the analysis-paralysis route), you can add the product for 2 weeks then re-test the bloods.
I've helped a number of patients with strange kidney diseases in this manner. Hope it helps.
