Could Iron Deficiency Explain Severe Fatigue and Nausea?
I am a 35-year-old female with a history of Polycystic Ovary Syndrome (which seems to be under control), endometriosis, and ongoing issues with nausea. It's been two years since giving birth. In mid-February, just prior to my menstrual cycle, I experienced an abrupt onset of intense anxiety, marked by night awakenings in a state of panic. This episode quickly subsided. However, on the second day of my period, I endured two nights plagued by night sweats, followed by overwhelming fatigue, dizziness, pronounced weakness, extreme nausea, and migraines that worsened towards the end of my cycle. Standing up made me feel faint, my legs ached, my stomach was upset, and my heart rate was noticeably elevated. This situation felt reminiscent of the iron deficiency anemia I encountered during my pregnancy, although the nausea now was far more intense. (During my pregnancy, my ferritin was recorded at 10ug/L, with low hemoglobin levels.) So far, the medical assessments have shown: - ECG results: Normal - Pelvic ultrasound: Normal - Blood tests: Full blood count, hemoglobin, liver, and thyroid results all came back normal - Ferritin levels: 20 ug/L (historically fluctuated between 20–30) - Serum iron: 9 umol/L - Iron saturation: 12% (marked as abnormal) - Transferrin: 3.34 g/L - HbA1c: 33 mmol/mol - Hormonal checks: Ovulation was confirmed, but my progesterone level was low for the mid-luteal phase (4.3 nmol/L on cycle day 21). After several days of rest and supplementing with 14mg of elemental iron daily, I have experienced a slight improvement, yet the episode left me feeling utterly depleted for almost two weeks. My general practitioner stated that my blood tests were “normal,” recommended over-the-counter iron supplements, and suggested that this might be viral in nature. He advised that if my condition doesn’t improve in two weeks, I should return for further consultation. Additionally, I have been referred to a breast clinic due to a lump suspected to be a fibroadenoma, and the timing of this has heightened my anxiety. I've also started to notice new symptoms, including mid-cycle cramps and breast tenderness, which have not been present before. Is it possible that mild iron deficiency, despite my normal blood count, could be the root of these symptoms? Should I advocate for further tests? This sudden and incapacitating illness has left me perplexed, especially as I had to take several days off my job. Any insights or reassurance during this time would be greatly appreciated.

It sounds like you're going through a challenging time with your health concerns, and it’s completely understandable to feel overwhelmed, especially with your history of iron deficiency and the new symptoms you've described. Let’s break down your situation.
Main Points
Your symptoms of severe fatigue, nausea, and anxiety may be related to mild iron deficiency. While your blood tests indicate normal hemoglobin and recent ferritin levels are slightly above your history of severe anemia, the low iron saturation suggests you might still benefit from further management.
Explanation
Iron deficiency can contribute to fatigue, weakness, and nausea, even if your complete blood count appears normal. Your body needs a certain amount of iron to produce hemoglobin, which helps transport oxygen. If your iron levels are low, it can lead to feelings of tiredness and other symptoms, such as those you've experienced.
Given your history of low iron during pregnancy, persistent symptoms, and recent hormonal fluctuations, a mild iron deficiency could indeed be influencing your current condition. It's also important to recognize that emotional stress, such as that from the suspected fibroadenoma, can exacerbate physical symptoms including fatigue and anxiety.
Next Steps
-
Continue Iron Supplementation: Since you’ve started taking 14mg of elemental iron daily and noted a slight improvement, keep taking it as recommended. Monitor your symptoms closely over the next week.
-
Dietary Adjustments: Incorporate iron-rich foods into your meals, such as red meat, poultry, fish, lentils, beans, and fortified cereals. Combining these with vitamin C sources (like citrus fruits or bell peppers) can help enhance iron absorption.
-
Monitor Symptoms: Keep a daily log of your symptoms, including fatigue levels, nausea, and any anxiety episodes. Note any changes in menstrual symptoms or newly experienced cramping. This can be valuable for any future consultations.
-
Follow-Up Care: Since your ferritin and iron saturation are concerning, it may be worthwhile to discuss repeat blood tests with your healthcare provider after a couple of weeks of continued iron supplementation. A referral to a specialist, such as a hematologist, could provide further insights if symptoms persist.
-
Stress Management: Engage in gentle stress-relief activities such as light exercise, meditation, or yoga if you feel up to it. Consider professional counseling, especially concerning your anxiety about the lump and other stressors.
-
Reassess Hormonal Balance: Given your low progesterone levels during the luteal phase, discussing these findings with a healthcare provider specializing in hormonal health is advisable. They can offer tailored recommendations for managing symptoms related to your menstrual cycle.
You are doing a commendable job by advocating for your health, and it’s important to keep communication open with your healthcare team. If your symptoms worsen or do not improve in the next week or so, do not hesitate to seek further medical advice. Your well-being is a priority, and you deserve clarity and support as you navigate these challenges.

Significant Bloating Following General Anesthesia
It has been just over a day since I underwent general anesthesia, and I currently feel as if I’m six months along in pregnancy. Despite only having a little food during this period, I am experiencing considerable discomfort, akin to having indulged in three feast meals! As a healthy 47-year-old woman who is not on any other medications, I underwent a dental implant procedure that was free of complications and did not require any pain relief medication afterwards. Could this sensation be attributed to gas, and if so, what could be causing it? How long might this discomfort persist? I have come across suggestions that using heat, peppermint, and engaging in walking or stretching may alleviate the situation. Are there any additional remedies or strategies that could provide relief?
Nosebleed Episode After Extended Dry Heaving
I’m a 28-year-old male, standing at 5'7.5" and weighing 280 pounds. My background is Jewish, though I don't believe that detail is particularly relevant here. I deal with various health conditions including Postural Orthostatic Tachycardia Syndrome (POTS), potential May-Thurner syndrome (still under evaluation by my doctor), restless leg syndrome, sciatica, spinal stenosis, plantar fasciitis, along with a range of mental health challenges. My current medications consist of minoxidil, lamotrigine, bupropion, and a low dosage of Xanax. Greetings everyone! I have been struggling with relentless bouts of retching—primarily dry heaves, akin to ‘morning sickness’—that have persisted throughout January and into February. I can’t pinpoint any changes in my diet, medications, or lifestyle that could have triggered this episode. Interestingly, I don't usually feel nausea in my belly; instead, it manifests mostly in my throat and chest. Although I suffer from GERD, this is an unusual level of discomfort for me. I normally manage it with calcium supplements and occasional omeprazole, but I keep that to a minimum to avoid additional stomach issues. Despite my efforts, my dietary choices aren't particularly acidic. I find myself expelling mostly saliva and stomach acid rather than actual food. Zofran hasn’t alleviated the persistent nausea I’m experiencing. I consulted my primary care physician about these issues, but unfortunately, his recommendations weren’t helpful. He implies that my nausea stems from not maintaining a proper diet, suggesting that if I could just afford better food, I wouldn’t have this problem. He was far from supportive, and to make matters worse, every GI clinic nearby isn't accepting new patients for months, so finding a specialist has been quite challenging. Today, during another episode of retching, I finally ended up vomiting a small piece of apple along with the usual saliva and stomach acid. This was alarming, but even more concerning was the sudden onset of a severe nosebleed. It wasn’t a mere trickle; blood was pouring from my nose, staining my chin and dripping onto the floor. I hurried to the bathroom and managed to curb the bleeding within five minutes, but the experience rattled me considerably. I felt dizzy and unsteady throughout the day following this incident. Could there be a link between the excessive vomiting and the nosebleed? Is it possible that such intense straining caused a rupture in a blood vessel in my nose? Additionally, I’m curious if anyone has insight into the cause of my persistent nausea. With the recent bleeding, my speculation leans towards an irritation in my sinuses causing me to unknowingly swallow blood at night, contributing to the nausea. Despite retching five to ten times daily, this sudden, severe bleeding is a new development. Thanks in advance for any advice or suggestions; apologies for the lengthy post!

Experiencing Sudden Neck and Head Pain – What Could It Be?
As a 17-year-old male weighing 59 kilograms, I occasionally encounter a sharp pain in my neck and head. This happens sporadically while I am simply sitting and unwinding. Whenever I turn my head slightly to either side, I suddenly experience a jolt of pain that travels from my neck to the area at the back of my head. Notably, this discomfort is not centered on my spine; rather, it occurs more toward the left and right sides at the back. Following this, I sense a chilling, almost icy feeling spreading across the back of my head, and gradually, the pain diminishes. Could you help me understand what this might indicate?
Persistent Lower Abdominal Bloating
Lately, I've been dealing with some unusual abdominal swelling. Prior to this, I've never really experienced bloating, but now it's been a consistent issue for the past two to three weeks. My lower abdomen appears rounded and expands further after eating, even if I consume only a small amount. Interestingly, I haven't noticed any changes in my weight—I remain the same, and the bloating is confined around my hips where I can still detect their outline. While I don’t feel any significant pain, some research I did mentioned that lower back discomfort might be connected, which I have occasionally felt, although it could simply stem from my poor posture. Additionally, I've noticed an increase in my burping, which leads me to suspect it might just be gas trapped inside me. I would really appreciate any tips or advice on this matter.
