Possible Reasons Behind Persistently Elevated MCV Levels Alongside Digestive Complications

8/9/2025, 7:30:41 PMMale25-34

I am 34 years old, standing 5 feet 3 inches tall and weighing 123 pounds. My heritage is a mix of Asian and White. I manage asthma effectively, have been diagnosed with ovarian endometrioma, struggle with androgenic alopecia, and might possibly be experiencing Irritable Bowel Syndrome (IBS). My alcohol consumption has recently decreased to two drinks weekly, and I do not use recreational drugs. The medications I take include montelukast, a Wixela inhaler, probiotics, digestive enzymes, oral minoxidil (which is currently on hold as I am undergoing an egg-freezing procedure), prenatal vitamins, and low-dose aspirin. Due to my upcoming egg retrieval, I underwent extensive blood tests. The initial results from early June showed a slight elevation in my mean corpuscular volume (MCV) at 98, although everything else was normal. My fertility specialist recommended I consult my primary care physician (PCP). However, the follow-up tests revealed a rise in MCV to 100, alongside slightly low red blood cell count and elevated iron saturation at 55%. This raised concerns about potential hemochromatosis, prompting another round of tests. In the latest testing, which focused on iron levels, methylmalonic acid (MMA), ferritin, folic acid, homocysteine, and a complete blood count (CBC), all parameters returned to the normal range except for a lingering high MCV of 99. Just this past week, I repeated the tests for a fourth time within two months, and my MCV remains at 100. I have yet to discuss these outcomes with my doctor, so I am uncertain of the next steps. In addition to these blood results, I have been grappling with undiagnosed digestive issues that have persisted intermittently for several years. My symptoms include sporadic right-sided abdominal pain accompanied by diarrhea. It is known that I am lactose intolerant, a condition identified in childhood. A previous PCP suggested I might have IBS. After my diagnosis of ovarian endometrioma last year, I opted for a Mirena IUD, adopted a diet aimed at reducing inflammation, and began taking digestive enzymes and probiotics. Consequently, my digestive discomfort has significantly decreased. My alcohol intake has notably diminished from approximately four drinks per week to eight per month, and I plan to abstain entirely from alcohol this month while I focus on the egg-freezing process. I have a follow-up appointment with a gastroenterologist next month, and I’m curious about what tests they might suggest. Additionally, my mother is battling stage IV cancer, so I'm anxious that my health concerns might point to something serious!

It's understandable to feel anxious given your situation with elevated MCV levels and digestive issues, particularly with your family health background. Elevated mean corpuscular volume (MCV) can be due to several factors, and your ongoing digestive symptoms may also be contributing to these concerns.

Main Points:

  1. Persistently elevated MCV can be linked to various conditions, including nutritional deficiencies, liver issues, or bone marrow disorders.
  2. Your digestive symptoms may be related to conditions like IBS or malabsorption, which can influence your overall health and blood parameters.
  3. It’s important to address both the elevated MCV and your gastrointestinal (GI) symptoms, especially since you have an upcoming appointment with a gastroenterologist.

Explanation:

MCV measures the average size of your red blood cells, and while a slight increase can indicate potential issues, it doesn't provide a complete picture. In your case, elevated MCV combined with low red blood cell count and high iron saturation could suggest several possibilities, including:

  • Vitamin deficiencies: Low levels of Vitamin B12 or folate can cause MCV to rise.
  • Liver health: Conditions affecting liver function (like alcohol use or certain medications) can impact blood cell production.
  • Bone marrow influences: Some disorders may affect red blood cell formation, but given your current blood tests returned to normal in other areas, this seems less likely.

Your digestive symptoms, including IBS and lactose intolerance, can lead to malabsorption of nutrients, which might exacerbate or explain the changes in your blood tests. Your focus on a diet to reduce inflammation is positive, and reducing alcohol intake further supports liver health and overall well-being.

Next Steps:

  1. Continue Your Dietary Adjustments: Maintain a balanced diet rich in whole foods, focusing on plenty of fruits, vegetables, whole grains, and proteins. This may help with both your digestive health and nutrient absorption.

  2. Stay Hydrated: Proper hydration is crucial for digestive health and overall bodily functions. Aim to drink enough water throughout the day.

  3. Monitor Symptoms: Keep a diary of your digestive symptoms, noting what you eat and when symptoms occur. This will provide useful information to your gastroenterologist and may help identify triggers.

  4. Prepare for Your Gastro Appointment: Write down your symptoms, current medications, dietary habits, and any blood test results showing MCV and iron levels. Discuss your concerns about the elevated MCV and get clarity on possible tests (like B12 and folate levels, liver function tests, or stool tests) that could be performed.

  5. Manage Anxiety: Given the stress around your mother's health, practice mindfulness or relaxation techniques that could help reduce anxiety. Consider speaking with a counselor if you find the anxiety feels overwhelming.

Above all, you're taking the right steps by following up with your healthcare providers. Keep track of your health closely and ensure regular communication with your specialists. If you experience any significant changes in symptoms, such as increased pain, fever, or significant changes in bowel habits, reach out to your healthcare provider sooner rather than later.

Could This Be IBS or Something Else?

Greetings! I’m a 27-year-old male, standing at 172 cm and of European descent, currently using Iqos. My medical troubles began roughly four months ago, around October 5, 2025. Initially, I experienced intense back pain lasting for two days, which I recognized as kidney stone pain. To alleviate this discomfort, I took NSAIDs, predominantly Metamizole-Natrium. Afterward, I visited urgent care, where I was given Diclofenac and Monural, an antibiotic for urinary tract infections. I took one of each at night. **A couple of days later, I started experiencing several troubling symptoms:** - Frequent diarrhea (4-5 times a day, often watery) - Significant gas and belching - Persistent nausea that greeted me each morning, sometimes relieved by eating - A general sense of malaise - A loss of 5 kg (I dropped from 63 kg) because I lacked appetite, especially under stress. These symptoms developed quickly and intensified through October, fluctuating over time. Blood tests showed no abnormalities, with normal CRP levels. Then in November, I underwent a colonoscopy and gastroscopy. - I had three very small erosions, about 1-2 mm, in the terminal ileum, but no signs of inflammation. Histology revealed no pathological issues, all was well. - There was one small erosion in the sigmoid colon, with minor inflammation around it. Histological findings indicated small infiltration in the lamina propria but no chronic signs, leading to a diagnosis suggesting a high likelihood of infection. - The areas were healing, with fibrin present. The rest of my colon appeared healthy. The doctor attributed the ulcers to NSAID-induced damage. I was later diagnosed with LA-A GERD. Due to my anxiety about health, I spent the month consumed by fears of complications such as colon cancer, PC, or Crohn's disease. I finally found some relief and felt symptom-free for the subsequent two weeks. However, in December the troubles resurfaced, though to a lesser degree, with occasional loose stools—2-3 times for a few days— and lingering gas. My anxiety about Crohn's returned, and I mistakenly took Algopyrin Complex, which triggered additional stress. **In December, my primary worries included:** - Loose stools resembling Bristol type 5-6, mainly occurring once each morning - Excessive gas often felt trapped in my rectum - My weight stabilized at 62 kg **I underwent various tests:** - Negative results for Giardia and E. coli - Negative FIT tests - Negative MRI (everything appeared normal) - Negative MRE (all normal) - Calprotectin level measured at 18.7 - I was found to have low levels of B9 and Vitamin D, with B12 at 320 and LDL at 5.9 **Moving into January:** - I only had one bowel movement each morning, sometimes loose, but mostly firm in the past three weeks (Bristol 4), compared to my usual Bristol 2. - After meals, I often felt gas building in my rectum, sometimes getting stuck before eventually releasing. This gas, thankfully, rarely had an odor. - Mornings have been troublesome, as I needed to pass gas 2-4 times, and in bed at night, I felt bloated with gas movements. **What I have observed:** - No signs of blood in my stools - No pain - No nocturnal symptoms affecting my sleep - No extraintestinal symptoms - My weight has stabilized without additional loss after recovering some weight Overall, I feel fine, yet the worry about my condition persists in my mind. Previously, I would have bowel movements twice weekly, with little to no gas. It baffles me that I often wake up feeling this uncomfortable. My primary concern is whether I should be worried about Crohn's disease (which occupies my thoughts constantly) or if my symptoms might stem solely from anxiety. Currently, I'm taking the following medications and supplements: - Itopride (doctor suggested it for motility issues) - L-Glutamine - Curcumin - A B-complex supplement - Ashwagandha - I briefly tried rifaximin for three days, but it did not yield significant changes. - I had also experimented with antacids previously, though they proved ineffective. Thank you for your assistance in advance!

Interpreting My Gastrointestinal Discomfort

A 26-year-old female, weighing 155 pounds, has a background of experiencing gastroesophageal reflux disease (GERD) and anxiety. She has been using marijuana for several years and is currently taking venlafaxine at a dosage of 150 mg each day. Residing in the Midwest USA, she identifies as white. On January 20th, she experienced what she initially believed to be a low blood sugar episode. Due to being preoccupied and busy, she had not consumed much food throughout the day. Consequently, she felt lightheaded, nauseated, pale, and was sweating. To alleviate these symptoms, she consumed around 60 to 80 grams of carbohydrates once they began, but it took roughly 2.5 hours for her to start feeling better. The following day, she faced additional discomforts including nausea, heartburn, body aches, trembling with chills and sweats, along with diarrhea. These symptoms persisted for a few days. By January 23rd, she consulted urgent care, where the medical team suspected a stomach virus and advised her to let it run its course. Regrettably, her stomach has not returned to its normal state since that incident. She has been experiencing occasional heartburn and indigestion reminiscent of her previous severe GERD episodes. Additionally, she is suffering from lower abdominal cramps, particularly triggered by consuming items like popcorn or spicy foods, which feels akin to irritable bowel syndrome (IBS) symptoms. During the height of her symptoms on January 20th, she ceased smoking. She partook in smoking a few times between January 24th and 28th, without noticing any changes in her symptoms – positive or negative – and has refrained from smoking since then. It is worth noting that she has not experienced any vomiting or severe abdominal pain typically associated with cannabinoid hyperemesis syndrome (CHS). Are her symptoms indicative of CHS? She intends to abstain from smoking yet seeks clarity on the underlying cause of her discomfort. She has read about post-viral IBS and is curious if the suspected stomach virus has reignited her GERD, which had been stable for several years.

Exploring Probiotic Effects and Antibiotic Strategies in Gut Health

Greetings, M30. Is it possible that consuming an excess of probiotics could lead to SIBO or a similar condition? Earlier this summer, I suffered from a campylobacter infection, and in an attempt to remedy that without realizing its full extent, I resorted to high doses of probiotics. This approach, however, only aggravated my situation. I experienced severe bloating, intensified brain fog—especially after consuming carbohydrates—and following a comprehensive examination of possible causes, including an initially misleading negative test for c. jejuni that later revealed IgG antibodies in my blood, I was prescribed rifaximin (200mg four times a day). Unfortunately, after five days of rifaximin treatment, my symptoms escalated dramatically, resulting in excruciating lower abdominal pain and a marked intolerance to carbohydrates. Through my research, I discovered that the probiotic strains I had been using were sensitive to antibiotics, so I requested that my physician switch my medication to amoxicillin, which promptly resolved the issues I was facing. Complicating matters, I later learned that I had been contending with an acute bartonella infection, which likely contributed to my motility problems. As the year progressed, I indulged in kimchi after having been on antibiotics for bartonella treatment for about a month. However, I had to stop the antibiotics over the Christmas holidays when I developed rashes from herpes on my face and required alternative treatment. Following my kimchi overindulgence, I began to experience bloating again, cognitive fog intensified, and I felt a toxin-like sensation after consuming larger amounts of carbohydrates, alongside a newfound intolerance to wheat products. My doctor once again prescribed rifaximin as the primary treatment, but I am starting to notice that familiar acidic sensation in my abdomen returning. Is this reaction indicative of die-off symptoms, or could it mean that rifaximin is targeting competitors of the kimchi bacteria in my gut, resulting in their proliferation and creating a cycle where lactic acid bacteria alter the colon's pH, promoting further growth of lactic acid producers? I suspect this situation mirrors what transpired during the summer months. Would switching back to amoxicillin be advisable, or might I need to consider amoxiclav instead, given that the kimchi contained fish sauce which might be a source of beta-lactamase? Best wishes,

Eight Years of Persistent ‘Hunger’—Is It a Functional Gut Disorder?

Greetings everyone, I’m a 28-year-old woman standing at 5 feet 4 inches, and for nearly eight years, I have struggled with a constant, hollow sensation in my upper abdomen that resembles hunger. Here are some key points about my experience: - This sensation arises between meals or soon after I have eaten. - It gets momentarily better after eating but eventually returns. - Though it feels like hunger, I know it's not genuine hunger. - Mornings are especially tough as the sensation intensifies. I maintain a regular meal schedule and consume enough calories without any restrictions. Currently, I find it difficult to trust my hunger cues, so I'm tracking my calorie intake. I do not take any medications and have previously used proton pump inhibitors without any noticeable improvement. Additionally, I neither smoke nor consume alcohol. Visits to my general practitioner have yielded no definitive diagnosis, with much of the feedback being centered on dietary adjustments. I am currently facing a waiting period of approximately eight months for a gastroscopy. Strangely, I also notice that I feel particularly weak during my workouts, despite my calorie intake being sufficient. Has anyone else faced a similar long-term issue? Did you find it to be functional dyspepsia, gastritis, visceral hypersensitivity, or something entirely different? Were you able to obtain assistance through a gastroenterologist, a dietitian, or therapy? Thanks for your insights!

Understanding My Lack of Appetite

I’m a 14-year-old girl about to turn 15, standing at 155 cm (5' 1'') and weighing around 53-54 kg. My exact weight remains unclear since I am battling anorexia and have been advised against using the scale. I am currently on a regimen of antidepressants (150mg of semonic daily) and antipsychotics (15mg of olanzapine). Along with my eating disorder, I've struggled with self-harm and have been diagnosed with a conduct disorder (though I'm unsure if that is the correct term in English as I'm receiving treatment in Spain). In September, coinciding with the start of the school year, I experienced a relapse regarding my eating disorder. This phase lasted a few weeks until I transitioned to homeschooling. Initially, recovery felt manageable; I experienced satiety quickly, and I was relieved to allow myself to eat once more. However, I’ve noticed a significant decrease in my appetite. I rarely feel hungry, and even when I do, it doesn't seem to bother me. I’ve lost the desire for typical meals, though I still find myself yearning for snacks, particularly sweets or salty options, which are much more appealing and easier to consume. Foods like rice are particularly challenging; I have to push myself to continue eating them because they don't excite me at all. I’m uncertain if this change is due to some underlying issue or merely stress, although I don't currently feel stressed. Perhaps my lack of physical activity contributes to my diminished appetite, as I haven't been particularly active and might not need as much food as others. It’s also worth noting that I haven’t grown taller for about a year or two, remaining at 5' 1''. This situation wouldn’t be as concerning if I weren’t dealing with anorexia, allowing me to simply eat less. Yet, given my background, I require supervision at mealtimes, which complicates my relationship with food. Whenever I lack the desire to eat, those around me jump to the conclusion that I am relapsing, which I am not. I enjoy food tremendously, especially sweets, and I snack throughout the day. It’s just the full meals that elude my cravings completely.
