Duration of Elevated Fecal Calprotectin Levels Post-Infectious Colitis

7/9/2025, 1:50:27 AMMale25-34

Age: 28, Male Non-smoker Height: 181 cm; Weight: 64 kg In late February and early March, I experienced a viral infectious colitis. My primary symptom was bloody diarrhea, which continued for two weeks without any accompanying pain. The symptoms ceased abruptly when I opted for a healing approach, relying on the BRAT diet and Pedialyte. As of today, July 8, I have been symptom-free for the past four months, experiencing no blood or diarrhea. I have noticed, however, that my digestive system seems more active than it used to be—particularly when I feel the urge to have a bowel movement or upon waking. Despite this, my stool consistency has largely reverted to normal, fluctuating between type 4 and sometimes mushy type 5, but I haven’t had any instances of watery stools like type 7. During my acute illness, I had a calprotectin test on March 8, which showed a reading of 2200. A follow-up test about 6.5 weeks later, on April 24, indicated a level of 229. The latest test on July 2 returned a value of 261, though this was conducted at a different laboratory with its own reference range. This leaves me questioning whether I should be concerned about the current reading. I’ve read that calprotectin levels can remain elevated for some time even after symptoms have resolved. How long can these levels stay elevated, and is it possible for them to take months or even a year to normalize completely? Additionally, I want to mention that approximately three weeks prior to my July 2 test, I experienced a mild case of food poisoning or gastroenteritis from June 8 to June 10, which involved vomiting and diarrhea after consuming contaminated food while traveling. Could this incident have contributed to the 261 calprotectin result? I hope to move past this episode and would prefer not to continue stool testing. I seek some reassurance on this matter, as I am no longer under a doctor's care (I’m in Canada, and the healthcare system is complex here).

It's understandable to feel concerned about your calprotectin levels after going through a viral infectious colitis and subsequent episodes of gastrointestinal distress. Here’s a breakdown of the main points:

Summary of Key Points:

  1. Calprotectin Levels: Elevated levels can occur after intestinal infections and may take time to normalize, but gradual decreases are common.
  2. Current Readings: Your recent reading of 261 is lower than previous levels, suggesting improvement but still warrants monitoring.
  3. Impact of Gastroenteritis: Your recent mild gastroenteritis could influence your calprotectin levels.

Explanation:

Calprotectin is a protein found in white blood cells, and its levels can indicate intestinal inflammation. After an acute infection like colitis, it’s common for levels to stay elevated, even after symptoms have resolved. While some people see normalization within weeks, in others, it can take months for levels to stabilize. Your decreasing trend—from 2200 to 261—indicates improvement, which is encouraging.

The mild gastroenteritis you experienced could potentially contribute to a temporary rise in calprotectin levels. These infections can result in transient inflammation, which might explain why you still see some elevation.

Next Steps:

To ensure you stay on the right track:

  1. Monitor Symptoms: Continue to track any digestive changes or new symptoms, focusing on consistency and frequency of bowel movements.
  2. Diet and Hydration: Maintain a balanced diet rich in fiber, fruits, and vegetables while staying hydrated. This supports your digestive health.
  3. Avoid Unnecessary Stress: Since you're no longer under direct medical care, it may be beneficial to manage your stress, as anxiety can impact gut health.
  4. Consider Follow-Up Testing: If you're feeling well but remain concerned about your calprotectin levels, consider discussing future testing only if symptoms return or persist.
  5. Empower Yourself with Information: Research information about gut health, gut flora, and lifestyle adjustments that may support recovery and function.

It's great to hear you’ve been symptom-free for four months, and maintaining healthy habits will aid your recovery. If you experience any new or worsening symptoms, stay attuned to your body. Your well-being is most important, so take things one step at a time. Let me know if you need more support or clarification on any points!

Assessing Blood Loss: When to Seek Medical Attention

A 43-year-old woman's experience sheds light on a serious health concern. She is a non-smoker, abstains from alcohol, and has a weight of 120 pounds. Recently, she underwent extensive abdominal surgery due to stage 3 rectal cancer, which involved the removal of her anus, rectum, and a significant portion of her large intestine, resulting in the creation of a stoma. This morning, she experienced abdominal discomfort coupled with noticeable bleeding in her ostomy bag. Feeling lightheaded, she decided to rest on a bed pad and utilized gauze to absorb the blood rather than risking further mess in her bag. The blood is emanating from her intestine, particularly from the area where stools typically exit, rather than from the surgical site itself. To manage the situation, she has been collecting the blood-soaked gauze in a bucket until they become fully saturated. Concerned about her condition, she seeks clarity on how much blood loss—whether by hourly measures or soaked dressing—would necessitate a trip to the emergency room. Additionally, she is pondering whether it would be wise to increase her water intake to compensate for potential blood loss. Earlier, she also noticed red vomit, which has made her cautious about consuming fluids quickly, as she fears it might trigger another bout of vomiting. As a single parent, she aims to avoid a hospital visit unless absolutely necessary.

Urgent Help Needed

I’m a 21-year-old female, weighing 174 pounds and standing 5’4”. Some health concerns began following unprotected intercourse. Lately, I've been dealing with frequent brown spotting alongside sharp, stabbing pains in my vaginal area, a tingling sensation, and a bothersome itchy feeling. Initially, the brown discharge occurred sporadically, but now it has become quite persistent, with no more than two days passing without noticing it. Additionally, my urethra sometimes appears red and swollen. I want to clarify that I’m not pregnant and have never used birth control. I've been tested for various STIs and yeast infections, although I haven't yet been assessed for HSV. Unfortunately, this issue has persisted for seven months. I’ve consulted four different gynecologists, and they all have said that my examinations appear normal. The most recent doctor suggested that my symptoms might stem from anxiety and stress, possibly linked to my previous relationship. I developed a fear of potentially catching something from my ex, which could be affecting me. Admittedly, I find that when I’m not preoccupied with worry, I feel perfectly fine most of the time, but I can’t shake off the anxiety about the brown spotting when I wipe. It feels unsettling and far from what I consider a normal condition. In terms of treatment, I have attempted various approaches including irritation creams, metronidazole, five doses of diflucan, clindamycin, and I’m currently trying an estrogen cream.

Experiencing Vision Disturbances: What Could It Be?

A 28-year-old woman has a family background marked by heart disease and hypertension. While working in her accounting role today, she experienced a peculiar visual phenomenon—a wavy, rainbow-like line appeared in her sight. This isn't the first occurrence; she recalls similar episodes at a previous high-stress job, but today she didn’t feel exceptionally pressured, despite some responsibilities weighing on her due to her regular partner being on vacation and her having to train a new colleague. However, the situation escalated as her peripheral vision in her right eye became increasingly affected. Afterward, she went home and took a nap, during which she also started to feel somewhat dizzy and nauseous, symptoms that were atypical compared to prior incidents. She has been taking citalopram for her anxiety for nearly nine years and feels worried about this episode. She wonders whether it is common for ocular migraines to manifest at this stage of life since she has never dealt with migraines before, with her first experience occurring only last year.

Assessing Functional Stomach Pain Without Additional Testing

Medications: None prescribed Chronic health issues: None noted I took my 3-year-old daughter to the doctor after she had been expressing discomfort in her stomach several times a day for the past three months. This began following a gastrointestinal infection for which she did not receive treatment at that time. During the consultation, after reviewing her medical history and examining her abdomen, the physician diagnosed her with functional stomach pain. The suggested course of action included incorporating probiotics into her diet, along with increasing her intake of fruits, vegetables, and water. While I found this explanation acceptable, my husband believes that additional tests should have been conducted to exclude other potential problems. We have since tried these recommendations, although we have not seen any improvement thus far. Interestingly, her stomach issues seem to occur independently of mealtimes or specific food items. We even attempted to reduce her dairy consumption to observe any changes, but there were no noticeable effects. She does mention her stomach discomfort more frequently when experiencing emotional distress, although this is not consistently the case. On a regular basis, she has bowel movements, typically several times a day, with stools primarily soft and occasional instances of diarrhea. Hard stools occur less than once a month. There are no urinary concerns to report.
