Possible Reasons Behind Persistently Elevated MCV Levels Alongside Digestive Complications
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:
- Persistently elevated MCV can be linked to various conditions, including nutritional deficiencies, liver issues, or bone marrow disorders.
- Your digestive symptoms may be related to conditions like IBS or malabsorption, which can influence your overall health and blood parameters.
- 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:
-
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.
-
Stay Hydrated: Proper hydration is crucial for digestive health and overall bodily functions. Aim to drink enough water throughout the day.
-
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.
-
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.
-
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.

Is It Normal to Repeat My Symptoms Several Times During a Medical Appointment?
Demographics: 32-year-old female, height 5'6", weight 162 lbs, non-smoker, currently on several medications not pertinent to this inquiry. I’m not entirely familiar with the typical procedures in larger hospitals, as I generally visit a small clinic where I only meet with my primary care physician. Recently, however, I was referred to a gastrointestinal specialist at a large hospital that seems to be affiliated with a university, although I’m unclear about the specifics of that relationship. At my usual clinic, I expect a nurse to check my vitals and ask a few preliminary questions related to my visit. On this occasion, initially, a nurse entered, took my vitals, and inquired about the purpose of my visit. Following that, another nurse—possibly in training—came in and asked almost identical questions while taking notes. Next, the GI doctor I had the appointment with arrived. He posed several more inquiries and shared his professional insights. Everything felt routine until after our discussion concluded; I thought I had shared all necessary information. I settled back to await any next steps, perhaps some follow-up paperwork. To my surprise, a fourth individual entered, introducing himself as another gastrointestinal doctor. Given his age, I presumed he held more experience or seniority than the previous physician. Unfortunately, he displayed that slightly condescending demeanor that some older men exude while engaging with younger women. Shockingly, he proceeded to ask me the same fundamental questions yet again—this time with seemingly no regard for the information I had already shared with both the nurse and the first doctor. This marked the fifth time I found myself recapping my personal history regarding sensitive issues like digestive discomfort and diarrhea, all while sitting alone in a room filled with three men. It felt quite awkward, to say the least. I wished I could have voiced my frustration, but my medical anxiety flared up, making me retreat into a people-pleasing mode that I am actively trying to manage. After this exchange, I received a stool test kit to take home before departing. Can someone explain why I had to recount my medical history repeatedly—to the first nurse, the second one, the doctor, and then a second doctor? The entire experience struck me as rather odd!
Abdominal Pain and Nausea After Standing: Seeking Advice
I usually consult my physician for health issues, but having recently relocated to a different city due to losing my job, I’m uncertain about the urgency of my current condition. I’m situated in the United States and would like to assess how critical this matter is so that I can effectively plan to apply for Medicare and arrange to see a doctor. Since I was a teenager, specifically at age 12, I have faced challenges with standing for prolonged periods. A diagnosis of adenomyosis at 21 revealed that my uterus is larger than average, which I discovered following surgery. To assist with mobility, especially on the expansive campus of my previous workplace, I've started using a cane. Just a few days ago, I attended a concert in my home state with friends who are unaware of my health struggles. I opted not to bring my cane this time, not wanting to engage in a conversation with my family as I have yet to disclose my situation. After standing for about an hour, the abdominal discomfort escalated to a point where I had to step away for 20 minutes to rest at a table. Despite having a very high threshold for pain, I experienced a level that was an 8 out of 10, and I found myself in tears. Once I returned, I managed to stand for another hour, but ultimately succumbed to vomiting due to the abdominal ache. The pain radiates from just beneath my ribcage down to my pelvis, accompanied by a constant feeling of bloating and fullness, regardless of how little I've consumed. I'm 5 feet 10 inches tall and weigh 135 pounds. Overall, I maintain good health and typically exercise 5 to 6 times each week, focusing on weight training to strengthen my leg, pelvic, and abdominal muscles, along with bouldering alongside my partner. Can anyone shed light on what might be happening? Should I seek medical assistance urgently? Thank you in advance for any guidance!
Persistent Lung Discomfort After Caffeine Overconsumption
Approximately a year ago, I consumed an excessive amount of coffee over a few consecutive days, with intervals of less than an hour between servings. Shortly after this experience, I began to notice discomfort in my lungs. This was accompanied by headaches and significant lung pain that persisted for a few weeks. Although the lung discomfort is not a frequent occurrence, it still flares up on occasion, and, while it can be intense, it’s not as severe as it once was. The most I ingested in one sitting was around 400 mg, which led to me unintentionally vomiting. At the time, I weighed about 100-110 lbs. I also recall a day, several months after my coffee overindulgence, when I took multiple caffeine pills at once. That night, I woke up trembling and struggled to return to sleep. I recognize that my actions were unwise, and I’m now concerned whether this has caused lasting damage to my lungs that might lead to issues in the future. Could anyone provide insight into the potential causes of my lung pain? I comprehend that caffeine was involved, but I had never experienced such lung discomfort prior to this incident. Therefore, I'm curious about how this caffeine intake could have impacted my respiratory health. I apologize if my English has any errors; I'm feeling a bit fatigued and it's not my primary language.
Stomach Pain and Diarrhea After Every Meal for Over a Month - A 22-Year-Old's Experience
I'm a 22-year-old male and I’ve been suffering from immediate stomach pain and diarrhea every time I eat for more than a month now. I haven’t experienced any vomiting or blood in my stool, nor do I feel nauseous; it's purely abdominal discomfort and frequent trips to the bathroom. The initial onset of the pain was excruciating. About thirty minutes after eating, I would find myself running to the restroom multiple times, often for up to five hours with persistent discomfort and loose stools. The pain is consistent, primarily localized in my abdomen, but oddly enough, it also radiates to my lower back every time. My diarrhea varies in consistency – sometimes I have slightly chunky stools, but often it’s as if I'm passing pure liquid. For instance, I had five instances today that fit this description. The coloration is also inconsistent. I suspect my dietary habits might be contributing to this problem. Since April 16th, I’ve adhered to a high-protein, almost carbohydrate-free diet, primarily eating chicken or beef cooked in a little oil, complemented by fruit, and only dining twice daily. I've completely avoided bread and only had a brief stint with rice. Could the absence of carbs be the culprit? I’m puzzled as to why these symptoms only began recently. After a few days of this discomfort, I consulted my physician who recommended trying Tums and a restrictive diet of just bananas, rice, and toast. At that time, I was hesitant to include carbs, which I now realize was misguided. I predominantly consumed bananas along with some other foods. I can’t confidently say whether the Tums had any effect, but I continued taking them for about a week. Additionally, I was prescribed a 50 milligram medication – the name of which escapes me now – to be taken for a week as a backup plan if dietary adjustments weren’t effective. On July 12th, the pain peaked, prompting a visit to the emergency room. I underwent blood and urine tests, both of which returned normal results. The nurses examined my abdomen but I didn’t exhibit any spasms or unusual reactions, which led them to rule out certain issues. They gave me a 100 milligram dose of the same medication from my doctor, but no CT scans were performed. The medical staff suggested it might just be a stomach virus, which could persist for around a week and advised me to go home. Following the prescribed medication and integrating rice back into my meals alongside my usual foods like bananas, I noticed some improvement towards the end of the treatment. While the pain wasn't entirely gone, it had lessened enough to manage. However, as soon as I completed the medication course, it seemed like the problem had resolved. Time passed, and while I had a few intermittent episodes of diarrhea, it largely subsided. That is until three days ago when the discomfort returned. This time, while the pain isn’t as severe as at its worst, it still interferes with my daily life and concentration. The diarrhea remains liquidy, similar to how it was previously. Just today, I ate a single meal after midnight – home-cooked chicken seasoned with a bit of oil and nothing more. Shortly thereafter, the familiar pain and diarrhea ensued, lasting until roughly 4:40 AM. I find myself frightened at the prospect of eating, dreading the inevitable return of discomfort. Yet, I recognize that I must nourish myself. The cycle feels hopeless. I truly need guidance and assistance with this situation.
Unusual Stomach Sounds
I am a 15-year-old female, standing at 5'6" and weighing 122 pounds. My medication is 100 mg of Seroquel, and I have never engaged in smoking or drinking. Lately, I've been experiencing some peculiar gurgling sounds from my stomach. The duration and location of these noises vary; sometimes they are prolonged, while at other times, they are brief. I’ve made attempts to alter my diet, but unfortunately, nothing seems to alleviate the issue. I’ve also increased my water intake, yet it hasn't yielded any positive results. This discomfort has persisted for quite some time. Interestingly, I haven’t noticed any unusual changes in my stool or digestive patterns aside from the gurgling noises. Additionally, I occasionally hear a strange croaking sound from my throat, resembling a burp. This noise tends to repeat and becomes quite persistent. Do you think taking gut health supplements would be beneficial? Would it be wise for me to consult a physician for further evaluation?
