People with inflammatory bowel disease tend to have lower levels of a specific protein called IPMK in their intestinal tissue, and this is linked to a greater leakage of the intestinal barrier.

We analyzed the available evidence and found that people with inflammatory bowel disease tend to have lower levels of a protein called IPMK in their intestinal tissue, and this is connected to increased leakage in the gut barrier [1]. This pattern was observed across all eight studies or assertions we reviewed, with none contradicting it. IPMK is a protein involved in cellular signaling, and in the gut, it may help maintain the tight connections between cells that line the intestine. When these connections become loose, substances that should stay inside the gut can leak out — a condition sometimes called “intestinal permeability” or “leaky gut.” The evidence we’ve reviewed suggests that lower IPMK levels may be part of why this happens in people with inflammatory bowel disease, but we don’t yet know if low IPMK causes the leakiness, results from it, or is simply present alongside it. We don’t have enough information to say whether this relationship is the same in all types of inflammatory bowel disease, or if it applies to everyone with the condition. The studies we looked at focused on tissue samples from affected individuals, but we don’t know how IPMK levels change over time or whether they respond to treatment. What we’ve found so far points to a consistent association between reduced IPMK and increased intestinal leakage in this group, but more research is needed to understand how or why this link exists. If you have inflammatory bowel disease, this doesn’t mean you should try to change your IPMK levels directly — there’s no proven way to do that yet. But it does highlight that gut barrier health may be an important part of managing the condition, and that’s something diet, stress management, and medical care can still support.
