Hidden Culprit Behind Draining Fatigue

A 20-year-old military police officer started seeing blood where it should never appear, and what doctors found during a colonoscopy changed everything about how he understood his own body.

Story Snapshot

Jesse Leon, a former military police officer, was diagnosed with ulcerative colitis after experiencing blood in his stool and severe fatigue.
A colonoscopy confirmed the diagnosis — the same gold-standard procedure clinical guidelines recommend for suspected ulcerative colitis cases.
Blood in the stool and extreme tiredness are two of the most recognized warning signs of moderate to severe ulcerative colitis.
Research shows self-reported inflammatory bowel disease diagnoses are confirmed by medical records 97% of the time, lending strong credibility to patient accounts like Leon’s.

When Blood in the Stool Is Not a Fluke

Most people who see blood in the toilet assume the worst for a moment, then talk themselves out of it. Jesse Leon could not do that. The blood kept coming, and so did the fatigue — the kind that makes a young, physically fit military police officer feel like he cannot get off the couch. Those two symptoms together are not random. Blood and extreme tiredness are hallmark warning signs of ulcerative colitis, a chronic disease that inflames the lining of the colon and rectum.

Ulcerative colitis, often called UC, is not a minor gut problem. It is an autoimmune condition where the body attacks its own colon lining, causing open sores, bleeding, and tissue damage. Symptoms can range from mild urgency to severe, life-disrupting flares. For Leon, the symptoms were serious enough to push him toward a diagnosis — and toward a platform where he now speaks openly about what he went through.

How Doctors Actually Confirm a UC Diagnosis

Getting a UC diagnosis is not simple. Doctors cannot just look at symptoms and call it done. Clinical guidelines say a colonoscopy with tissue samples taken from multiple sections of the colon is the preferred path to a confirmed diagnosis. The procedure lets a gastroenterologist see the inflammation directly and collect biopsies that show what is happening at the cellular level. Doctors also need to rule out infections like Clostridioides difficile, Campylobacter, and E. coli O157:H7, because those bacteria can mimic UC symptoms almost perfectly.

Blood tests also play a role. Doctors look at inflammatory markers like C-reactive protein and erythrocyte sedimentation rate, plus a stool test called fecal calprotectin, which flags intestinal inflammation. A low hemoglobin level can confirm that ongoing blood loss has already started affecting the body. Severe UC has specific thresholds — a C-reactive protein above 45 mg/L or hemoglobin below 105 g/L are red flags that doctors take seriously. Leon’s case followed this diagnostic path, with the colonoscopy serving as the confirming step.

Why Patient Self-Reports Deserve More Respect Than They Get

Some people hear a patient tell their story on video and immediately wonder whether the diagnosis is real. That skepticism is understandable but not well-supported by data. A large study of the Crohn’s and Colitis Foundation’s patient research cohort found that self-reported inflammatory bowel disease diagnoses were confirmed by medical records 97% of the time when records were eventually reviewed. Patients also accurately reported their specific disease type and surgical history. That is a remarkably high accuracy rate for self-reported health information.

Leon’s advocacy work — encouraging patients to push for answers and seek multi-faceted treatment — fits squarely within what medical experts recommend. Patients who understand their disease and actively participate in their care tend to have better outcomes. That is not a soft opinion; it is a documented pattern in inflammatory bowel disease management. Self-advocacy is not a buzzword here. It is a clinical strategy.

What a Military Background Adds to This Story

Being a military police officer at 20 years old is a high-stress job by any measure. The physical demands, irregular hours, and psychological weight of law enforcement work inside a military environment are well documented. Stress does not cause ulcerative colitis on its own, but it is a known trigger for flares in people who already carry the underlying condition. The connection between Leon’s occupation and his symptom onset is worth noting — not as a definitive cause, but as important context for anyone in a similar high-demand job who may be brushing off symptoms they should not ignore.

The Bigger Warning Most People Miss

Ulcerative colitis has a well-known problem: people wait too long to get checked. Surveys of UC patients show that many accept bleeding, fatigue, and cramping as their new normal, even during periods they describe as remission. That acceptance is dangerous. The disease can progress silently between flares, and delays in diagnosis are common. Leon’s willingness to share his story publicly — colonoscopy and all — puts a human face on a condition that affects roughly 900,000 Americans and tends to strike people during their most productive years. If blood and fatigue are showing up together, that is not a combination to wait out.
