The short version: medicine has almost nothing proven to offer for persistent post-COVID GI symptoms at 30 months, and the evidence retrieved does not contain a single treatment trial for this exact condition.

The evidence you retrieved is almost entirely about describing the problem, not solving it. The VA cohort study [3] and the Bronx study [1] document that GI symptoms persist for one to three years after infection, with hazard ratios between 1.18 and 1.54 for various outcomes. The systematic review [2] found persistent GI symptoms in 10.8% of infected people versus 4.9% of controls. But none of these studies tested a treatment. The one intervention study in the evidence is about feeding tube placement technique in ICU patients [4], which has nothing to do with an older adult at home with lingering gut symptoms.

The 2026 review on functional GI disorders in IBD [9] is the closest thing to a treatment framework, but it addresses inflammatory bowel disease, not post-COVID GI symptoms. It does describe approaches that might apply: testing for small intestinal bacterial overgrowth (SIBO), bile acid diarrhea, and pancreatic insufficiency, then treating those specifically. But this is extrapolation, not evidence for this population.

What is knownWhat is not known
GI symptoms persist at 30 months [1, 3]No treatment trial for post-COVID GI symptoms exists in this evidence
Risk is 18-54% higher than controls [1, 3]No comparison of drug vs placebo for this condition
Mechanisms include dysbiosis and spike persistenceNo tested protocol for gut restoration

My call: the evidence retrieved does not support any specific medical intervention for persistent post-COVID GI symptoms at 30 months. The honest answer is that nobody has run the trials. Confidence: high that the evidence gap is real.
