Unexplained Midday Exhaustion
Age: 27, Weight: 130 lbs. For as long as I can remember, I've been plagued by an overwhelming fatigue that particularly hits me in the afternoon without any clear reason. I'm describing a level of tiredness where I could easily take lengthy naps of 4 to 6 hours during the day. In my younger years, I often found myself dozing off in class, and after school, I would routinely crash for hours, sometimes right until evening. Currently, I resist the urge to nap because I struggle to keep those naptimes short; they often lead to extended sleep and complications with my nighttime rest. Typically, I experience peak tiredness between 1 PM and 5 PM, although there are days when it extends until 8 PM. By the time evening rolls around, I often feel quite alert. Mornings, however, are a challenge. Rising from bed can be tough, and I often experience sleep inertia, which complicates my morning routine. Once I manage to get up, I usually feel sufficiently awake, only to face this tiring slump come midday. Throughout the years, I've undergone various medical check-ups, including thyroid functions and iron level assessments, all of which returned normal results. The last iron test I had, about a year and a half ago, indicated that my iron levels were acceptable, but my ferritin was low, around 14. I tried taking iron supplements for a couple of months to see if they would alleviate the fatigue, though I didn’t notice significant changes. I maintain a nourishing plant-based diet that includes ample amounts of healthy fats, carbohydrates, and proteins. My hydration levels are good, aiming for 60-80 ounces of water daily. I make it a point to exercise most days, engaging in activities like yoga, swimming, jogging, and weight training. Typically, I get between 7 to 10 hours of sleep each night. Regardless of whether I get less or more rest, I still wake up feeling drained the next day. During these episodes of profound exhaustion, my entire body feels heavy—my limbs weigh down, my eyes grow tired and heavy, my heart races, and I feel a general sense of sluggishness. What could be the underlying issue? Am I destined to experience this relentless fatigue for a significant portion of each day indefinitely?

It sounds like you're experiencing a significant and persistent fatigue that impacts your daily life, particularly in the afternoons. Understanding the nature and potential causes of your fatigue is crucial, and it’s commendable that you're seeking insight into this troubling issue.
Explanation
Your symptoms suggest that you are battling something more than just typical tiredness. The mid-afternoon slump, severe urges to nap, and waking up feeling drained after adequate sleep point to potential underlying issues, even if preliminary blood tests (like those for thyroid and iron) have returned normal results.
Some possibilities that could contribute to your fatigue include:
- Circadian Rhythm Disorders: Whether from lifestyle factors or other underlying conditions, disruptions in your biological clock can lead to excessive daytime sleepiness.
- Sleep Quality: Despite getting a good amount of sleep, factors like sleep apnea or poor sleep quality could be causing you to feel unrefreshed.
- Dietary Considerations: While you maintain a plant-based diet, insufficient intake of specific nutrients (like B12, Omega-3 fatty acids, or other micronutrients) can contribute to fatigue.
- Chronic Fatigue Syndrome (CFS): Symptoms resembling yours may align with this condition, which is characterized by prolonged fatigue that doesn’t improve with rest.
- Mental Health: Stress, anxiety, or depression can also manifest through physical symptoms like fatigue, which is not uncommon.
Prioritized Next Steps
-
Track Your Energy Levels: Keep a diary of your daily energy levels, diet, hydration, sleep quality, and workout intensity over the next couple of weeks. This will help identify patterns and potential triggers.
-
Consult a Sleep Specialist: Given your symptoms, especially morning grogginess and exhaustion, it might be beneficial to explore issues like sleep apnea or other sleep disorders.
-
Review Your Diet: Assess if you’re meeting all your nutritional needs. Consider consulting with a registered dietitian familiar with plant-based nutrition to ensure you get an adequate supply of all essential nutrients, particularly Vitamin B12 and Iron.
-
Regular Rest Breaks: Given your fatigue levels, try to schedule short breaks during the day. Even 10-15 minutes of relaxation or gentle stretching can help refresh your energy without risking a long nap.
-
Medication Review: If you’re on any medications, review with a healthcare provider whether they could contribute to fatigue.
Taking these steps could help you understand and manage your fatigue more effectively. You’re not alone in this, and many individuals experience similar challenges. Please feel free to reach out for further support or clarification.

Struggling with Fatigue and Low Spirits
I am a 27-year-old male whose first language is not English. A psychologist with two decades of experience in autism has diagnosed me with this condition. I previously took olanzapine, which caused an unusually long sleep of 20 hours during my first dose; however, I’ve stopped using it since then. While I was taking a sublingual form of vitamin B12 (methylcobalamin) at a dosage of 1000 mcg, my serum level registered at 290 pg/mL. This led to an unexpected surge of energy accompanied by feelings of anxiety and restlessness that I couldn't quite articulate, lasting for over six hours. I suspect that I might have a particularly sensitive nervous system. I'm contemplating whether to resume my B12 supplementation, as well as starting vitamin D3 at a dose of 2000 IU. Prior to taking D3, I found my levels to be very low, around 15 pg, though I can't recall the European unit it corresponds to at the moment. Additionally, my TSH level has been measured at 4, and I've been diagnosed with Hashimoto's disease. I’m currently at a loss as to why I continue to experience fatigue and a low mood. Does anyone have suggestions or insights that could help?
Chronic Leg Discomfort Since Childhood
I am a 14-year-old female who has experienced persistent discomfort in my legs for as long as I can recall, and the cause remains unclear. The maximum duration I can manage to walk without feeling faint is around 10 minutes, while I can only walk for about 5 minutes without needing to pause. Even when I’m at rest, I feel a dull ache in my legs, despite the rest of my body feeling relaxed. This discomfort predominantly occurs around my joints, particularly my knees and ankles, although my calves also become tender with minimal exertion. My feet tend to be perpetually cold, rarely warming up even when the rest of my body does. During my menstrual periods, I find it extremely difficult to walk, often having to hold onto walls just to navigate short distances. I've always maintained a healthy weight and I don't consider myself unhealthy overall. The only medical condition I’ve been officially diagnosed with is autism, although I'm unsure if this has any relevance to my symptoms.
Seeking Help for My 5-Year-Old Son with Autism and Constipation Issues
Hello, I am reaching out regarding my 5-year-old son who is non-verbal and has autism. He also shows signs of ADHD, although this has not yet been officially diagnosed. Typically, he is very energetic, cheerful, and expressive. He thrives in his school environment, where he is supported by a wonderful team of special education teachers. He doesn’t take any regular medications, except for melatonin to assist with his sleep. Recently, on December 19th, he developed a rash while at school, which resembled hives on his neck, face, and feet, with accompanying swelling in his hands. By the time we went to urgent care, the rash had disappeared, and he was given Benadryl. Unfortunately, the rash recurred a couple of times at home, though we only administered Benadryl on two occasions. Following this, during Christmas break, I noticed he became increasingly emotional, crying daily, appearing more fatigued, and having less energy overall, although he was usually still able to be comforted. I visited the pediatrician twice during this period, and lab tests came back normal, except for a positive COVID-19 result. The doctor prescribed guanfacine and clonidine for him (I apologize if I spelled those incorrectly), but I chose not to give him these medications since they weren't intended for behavioral issues. When school resumed, for the most part, he seemed to manage well until last week when he experienced another rash episode at school, occurring twice. I decided to try a non-drowsy allergy medication for him, but his emotional state deteriorated again, leading him to cry throughout the school day. His teachers expressed concern, stating that he appeared to be in discomfort, which they confirmed is not related to behavioral issues. At home, he has been very upset and inconsolable. As a result, I took him to the hospital yesterday. They sedated him for a head CT and abdominal ultrasound, both of which showed no abnormalities. They prescribed Miralax and suggested looking into ABA therapy since his autism diagnosis may automatically point to behavioral factors, which frustrated me. Today, he has spent the entire day crying and has remained in bed, clearly exhausted. I am administering the Miralax, and he seems visibly uncomfortable, but he hasn't had a bowel movement yet. His last stool was two days ago, and only a tiny amount has come out since then. I’m uncertain if the rash and his current symptoms are related to constipation or if I am missing a more serious issue entirely. This is very distressing. We have a dental appointment scheduled for Tuesday to rule out any dental issues, our fourth visit with the pediatrician on Wednesday, and a phone consultation with an allergist also on Wednesday. I would greatly appreciate any insights or questions I should bring up during our pediatrician visit, as well as any tips or suggestions. I'm feeling quite desperate for help. Thank you!
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!
