The bloating, the new food reactions, the brain fog that lifts and returns, the sense that your digestion turned on you after COVID. It is not in your head, and it may start in your gut. When the microbiome, the community of organisms in your intestines, is thrown out of balance and the gut barrier is disrupted, the effects reach far beyond digestion.
Volume 4 covers gut dysbiosis, one of the six root mechanisms behind Long COVID. It maps how a disrupted gut drives symptoms far from the gut, and how to start repairing it, in plain language you can work through with your clinician.
What you’ll find
Most advice treats the gut and the brain as separate problems. This volume follows the connection between them, because for many patients the road back runs through the microbiome.

Robert Groysman, MD
He began treating Long COVID before it had a name, after a stellate ganglion block unexpectedly restored the taste and smell in his post-COVID patients. That was the first clue that something deeper was going on.
He has experienced Long COVID himself. This series is based on findings in his own practice.
Written for a patient, not a textbook
“Immensely helpful. The explanations are clear and accessible, and the treatment plan is practical and methodical. I ordered the rest of the series, and I am understanding so much more now.”
Reading the whole framework?
Gut dysbiosis is one of six mechanisms. The seven-volume set covers all of them and saves you $18.93 over buying each book on its own.
