Struggling to Stay Alert Post-Meal: Seeking Answers
I’m an 18-year-old female, weighing 75 kg and standing at 5'6". After nearly every meal, especially in the evenings, I find myself battling to remain awake. It’s particularly pronounced after dinner; the fatigue feels overwhelming, as if my face is swollen and there's a burning sensation in my blood. This issue has persisted for several years, dating back to when I was around 13. My typical diet includes rice and a variety of South Asian dishes, with occasional pasta and pizza. The struggle to stay alert is exhausting, and if I sit on my bed following a meal, I invariably drift off and end up napping for hours. Initially, I suspected that my fatigue was linked to high sugar intake, so I eliminated sugar and dairy from my diet for an entire month, yet the drowsiness persisted. While I’m neither diabetic nor pre-diabetic, it’s noteworthy that many family members do have diabetes. About a month ago, I underwent a comprehensive blood analysis, which revealed mostly normal results, apart from low calcium levels (2.29 mmol/L), transferrin saturation (14.7%), RDW (11.3%), lymphocytes (3.25 x 10^9/L), and eosinophils (0.53 x 10^9/L). Despite a random weight gain of 20 kg toward the end of 2022, I've struggled immensely to lose any of it. I’ve been consistently walking 10,000 steps per day with little to no change. Over the years, I’ve had multiple blood tests that mostly returned normal results, except for some low vitamin D, for which I was prescribed supplements. My doctor assured me that experiencing tiredness after meals is quite common and that it's not a symptom of diabetes. I regularly consume milk, which makes my low calcium levels puzzling. Nevertheless, I am still fighting for the strength to stay awake following my meals. Even as I draft this message, fatigue washes over me, my face feels sore, and there’s an uncomfortable sensation in my blood—if that even makes any sense. Is there anyone who might have insights or suggestions? What steps should I take if my doctor continues to insist that this fatigue is normal?

It sounds like you're dealing with significant fatigue after meals, particularly at dinner, which is understandably concerning. This can be frustrating, especially when you feel you've made efforts to eliminate sugar and dairy. Let's break this down and explore what might be happening and how you might address it.
Main Points:
- Post-Meal Fatigue: Experiencing tiredness after eating is common but can sometimes indicate underlying issues that merit further exploration.
- Potential Causes: Factors like dietary composition, low calcium, low vitamin D, and possibly imbalances in hormones or blood sugar can all contribute to post-meal sleepiness.
- Next Steps: Focus on dietary adjustments, monitor your body's response, and evaluate your symptoms further.
Explanation:
Post-meal fatigue can result from various factors, including the types of food you eat, your body's metabolic responses, and potential nutritional deficiencies. When meals are high in carbohydrates, for instance, they can lead to increased insulin production, which might make you feel sleepy. Your mention of low calcium and vitamin D could suggest that some nutritional deficiencies might also be involved.
Actionable Steps:
-
Dietary Adjustments:
- Balanced Meals: Try to include a balance of proteins, healthy fats, and complex carbohydrates in your meals. Consider adding more vegetables and lean proteins (like chicken or legumes) to your diet to slow carbohydrate absorption.
- Smaller Portions: Instead of large meals at dinner, consider smaller portions or multiple small meals throughout the day to see if this helps with fatigue.
- Hydration: Ensure you stay well-hydrated throughout the day. Sometimes fatigue can be exacerbated by dehydration.
-
Monitor Food Reactions:
- Food Diary: Keep a food diary to track what you eat and how you feel afterward. Note any specific foods that seem to correlate with increased fatigue.
-
Address Nutritional Deficiencies:
- Calcium and Vitamin D: Since you have low calcium levels, continue to monitor this with your healthcare provider. Consider discussing dietary sources of calcium (like leafy greens, fortified plant milks, or fish) and vitamin D (like fatty fish or fortified foods). Make your supplement plan clear with your doctor regarding the correct dosage and duration.
-
Physical Activity:
- Post-Meal Activity: After eating, engage in light activity, such as walking, to help stimulate digestion and reduce feelings of fatigue.
-
Sleep Hygiene:
- Evaluate Sleep Patterns: Ensure you have a consistent bedtime routine and quality sleep each night, as irregular sleep can contribute to daytime fatigue.
If your symptoms persist despite these changes, it may be worthwhile to seek a second opinion from another healthcare provider or a specialist, like a nutritionist or an endocrinologist, to explore other potential underlying causes.

Experiencing Heart Pounding and Exhaustion?
Over the past month, I've been encountering episodes where I suddenly feel extremely fatigued. These moments often come hand in hand with a headache or distorted vision, and I also notice my heart racing significantly. Typically, these spells last anywhere from one to four hours. During these times, I’ve monitored my pulse, which peaks at around 110 beats per minute; however, what alarms me more is the intensity of the pounding sensation. Should I be worried about this? Is it indicative of any specific health issue that I should investigate? **Personal Details:** - Female, 30 years old - Height: 5'3"; Weight: approximately 178 pounds - Diagnosed with Ehlers-Danlos Syndrome - Diagnosed with Mast Cell Activation Syndrome - Chronic Migraine sufferer - Suspicion of an autoimmune disorder - Current medications include Cromolyn (for mast cell stabilization), Tylenol, and Xyzal.

Seeking Guidance on Antidepressants for Severe Depression with Hyperadrenergic POTS
Hello, everyone. I am currently living with a chronic illness that includes Hyperadrenergic POTS, Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME), and persistent pain, which has led to my disability status. Over the past two years, I have experienced severe depression and anxiety, stemming from a sudden life change and the trauma that accompanied it. Due to my condition, I am mostly confined to bed, and this lifestyle shift from being a previously active individual to someone who cannot walk much has deepened my feelings of sadness. Unfortunately, the therapists I have consulted seem unable to grasp the complexities of my medical issues and are hesitant to prescribe any medications. I am currently on a waitlist for nine months just to see a specialist experienced with POTS in my country. Next week, I plan to discuss this with my primary care physician, but I’d like to hear your thoughts beforehand. Many medications have an energizing effect on me, leaving me feeling overly stimulated and disrupting my sleep patterns. I experience symptoms typical of POTS, including significant heart rate increases when I stand, which is accompanied by overwhelming fatigue and an adrenaline-like sensation, including symptoms like palpitations and restlessness. During flare-ups, my insomnia and melancholic feelings intensify, contributing to my overall exhaustion. I alternate between feeling fatigued yet wired, enduring insomnia, and grappling with the sorrow of being unable to engage in activities due to the extreme fatigue and post-exertional malaise. My current medication regimen includes: - Ivabradine: 10 mg daily - Pyridostigmine: 120 mg daily - Pregabalin: 150 mg daily (tapering off due to inefficacy for pain) - Dayvigo: 5 mg at night - Rosuvastatin: 20 mg at night As needed, I take: - Tylenol #3 very rarely (about once every three days max) for pain episodes - Ubrelvy for migraine - Celecoxib as needed - Allegra and Pepcid as needed I am curious about which antidepressants might be suitable for someone in my situation, particularly considering my insomnia and anxiety, along with the underlying dysautonomia/POTS. I also have concerns about medications that may lessen the efficacy of codeine, as I occasionally rely on it for pain management. If duloxetine is a potentially viable option for enhancing my mood and addressing my racing thoughts, would it be feasible to continue using codeine on an as-needed basis, or would a different pain management approach be advisable instead? To provide some context, I am a 35-year-old male residing in Iran. Previously, I have tried various antidepressants; for instance, amitriptyline worsened my POTS symptoms due to its anticholinergic side effects, while escitalopram changed my personality significantly, leaving me feeling emotionally numb. At this time, I am not taking any antidepressants. I also do not have any known allergies.
Seeking Guidance for Overwhelming Anxiety
I’m a 22-year-old man in desperate need of advice regarding a recent troubling experience. Previously, I managed to cope with silent panic attacks quite well; however, about three days back, while watching a YouTube video that critiqued some dogmatic ideas, I was suddenly hit by a severe panic attack. I still can't pinpoint the trigger for it. Since that incident, I’ve been trapped in a relentless cycle of anxious thoughts. It feels as if the world around me isn’t real, which has created an urgent desire to scream and cry. Even as I write this, I find myself struggling to breathe, and my arms have begun to tremble and lose feeling. Although I rationally know I should be okay, fear still grips me. To provide some context, I had been a daily cannabis user, although I doubt it’s the root cause of my current distress. In an attempt to mitigate my symptoms, I have decided to stop using it, including cutting out nicotine. I believe that before seeking mental health support, I should first undergo a physical health check-up; however, without health insurance and being currently unemployed, I find myself in a difficult situation. Fortunately, I am living with my parents, which allows me to manage day-to-day needs, but I am eager to overcome these feelings so I can return to work and support those around me. What steps would you recommend for someone in my position?
Understanding Abnormal Lab Results
Greetings! I am a 25-year-old female, weighing 170 lbs and leading an active lifestyle, engaging in physical activities about four to five days each week due to my job. Recently, I underwent a physical examination as I wanted to address several troubling symptoms that include persistent fatigue, excessive daytime drowsiness, joint pain and rigidity (especially noticeable in the mornings), recurrent headaches, and a growing difficulty in moving my lower extremities after being seated for a while. Occasionally, I experience numbness and tingling sensations in both my arms and legs, alongside symptoms resembling Raynaud’s phenomenon. Throughout most of my life, I have experienced heavy periods that have been quite exhausting, yet over the past couple of years, I have noticed a significant increase in my fatigue even outside of my menstrual cycle. Upon reviewing my recent lab tests, a few concerning results emerged: - Ferritin levels are at 13, down from 15 nearly a year ago. - Iron saturation is recorded at 12, having decreased from 33. - Although my iron levels remain relatively stable, they have fallen from 118 to 42. - Cortisol appears low at 5. - Vitamin D measures at 25.8. - A positive ANA test shows a 1:80 speckled pattern. Additionally, my rheumatoid arthritis factor was 11.2, which falls within the normal range, and my anti-chromatin level is at 0.5. Other tests such as thyroid function, hormone levels, and lipid panel results are normal, and there are no indications of diabetes. As a child, I once dealt with a swollen lymph node on the left side of my jaw, and ever since, I have experienced discomfort and a feeling of fullness in my upper left abdomen just behind my ribs. An ultrasound confirmed an enlarged spleen, which has become increasingly uncomfortable lately. I'm seeking clarity on these lab findings ahead of my upcoming appointment with my primary care physician. I am also making an effort to modify my diet and lifestyle, but it proves challenging given how unwell I often feel. Thank you for your assistance!
Next Steps for an 81-Year-Old with Active Lymphoma and Severe Insomnia
**Patient Age:** 81 years **Gender:** Female **Approximate Height:** 5'4" **Approximate Weight:** 48.8 kg **Ethnicity:** Caucasian **Residence:** United Kingdom **Pre-existing Health Issues:** Sjögren’s syndrome, active and recurrent lymphoma, previous pneumonia episode (1 year prior), severe insomnia **Current Medications:** Recently tested Zopiclone 3.75mg (starting with half a tablet, then increasing to a full tablet). Various herbal and homeopathic solutions have also been attempted. **Duration of Insomnia:** 1 year, consistently worsening I am writing this on behalf of my mother. At 81 years old, she is unable to navigate Reddit herself. For many years, she has been battling Sjögren’s syndrome, which progressed into lymphoma in 2011. She underwent surgery to remove half of her right lung and has been under surveillance since. Unfortunately, two years ago, the lymphoma re-emerged, and after four treatment cycles that offered an initial positive response, the disease has again intensified and expanded. Since being treated for pneumonia about a year ago, she has been experiencing significant sleep disturbances that have progressively worsened. Early on, she could manage to sleep for a couple of hours at a time; however, she now frequently finds it impossible to sleep. Recent episodes have seen her awake for nearly 36 hours straight. While she feels profoundly fatigued, her mind remains in a state of heightened awareness when she attempts to rest. Her daily functioning has been severely compromised, leading to a noticeable decrease in her appetite. She believes the persistent lack of sleep is exacerbating her overall health challenges. Despite attempting various over-the-counter sleep aids—such as sleep patches, honey, and homeopathic remedies—none have had the desired effect. After some difficulties in accessing her NHS GP, she opted to consult a private doctor who prescribed Zopiclone at 3.75mg, advising her to begin with half a tablet. She reported sleeping only about an hour the first night, and after increasing her dosage to a full tablet, she only managed about two hours of sleep and felt weak and unsteady afterward. Due to challenges in securing a medication review linked to obtaining GP appointments, she has yet to receive a comprehensive reassessment. Her oncology doctor has emphasized the necessity of communicating with her GP about her condition. **My inquiries are as follows:** 1. Is it required that all referrals go through the GP? 2. Is severe insomnia frequently encountered in patients with active lymphoma or ongoing autoimmune conditions? 3. Based on her symptoms, could the cause be more neurological, hormonal, related to medications, or attributable to anxiety? 4. Which medical interventions are usually explored when Zopiclone is ineffective or poorly tolerated in elderly individuals? 5. Are there safer or more effective alternatives suited for her age and health status? 6. Should this predicament lead to an urgent medical evaluation? She is truly struggling and her health is declining due to exhaustion. Any insight regarding potential causes or subsequent actions would be immensely helpful.
