Curious Case of Sugar Reactions
Hello! I am a 22-year-old transgender male, standing at 5 feet 4 inches tall, weighing 120 pounds. I do not engage in smoking or drinking alcohol. My birth was quite early at 27 weeks, and I have an identical twin. I also have a minor lesion on my occipital lobe, which my neurologist believes is a result of my early birth. In terms of my neurological health, I hold diagnoses for ADHD, Autism, and several other neurodivergent conditions. Recently, in early 2024, I was diagnosed with sudden onset severe MCAS. Currently, I manage my conditions with lamotrigine and antihistamines. Since childhood, I have experienced what I refer to as a "sugar fever" whenever I consume sugary foods. This phenomenon sees my body temperature rise from a normal level of around 98.6°F to as high as 101.1°F. Despite consulting various doctors, no one has been able to identify the cause of this reaction. My symptoms manifest shortly after eating items like chocolate, cake, cookies, or mangoes; within minutes, I begin to feel flushed and warm. Typically, this fever lasts about twenty minutes, but the duration varies depending on the quantity ingested. I'm reaching out to see if anyone else has encountered something similar or could shed light on what might be happening in my body?

It sounds like you're experiencing a concerning reaction to sugar, often referred to as "sugar fever." This can be quite uncomfortable and puzzling, especially given your complex health background, including MCAS (Mast Cell Activation Syndrome), which you're currently managing.
Explanation of "Sugar Fever"
When people consume sugary foods, their bodies can react in various ways. In your case, it seems like you might be experiencing a heightened histamine release or mast cell activation in response to sugar. This could explain your symptoms of feeling flushed and having a temporary rise in body temperature. Essentially, your body may react as if it’s fighting off some kind of irritant, leading to fever-like symptoms.
Next Steps
Here’s a structured approach you can take to manage your symptoms effectively:
-
Monitoring:
- Keep a Journal: Track what foods trigger these reactions, how long they last, and any accompanying symptoms. This will help you identify patterns and discuss them with your healthcare providers.
-
Diet Modification:
- Limit Sugars: Try to reduce or eliminate sugary foods and drinks from your diet, particularly those that you know cause a reaction. You might find alternatives to satisfy your sweet tooth, such as fruit in moderation or sugar-free products.
- Consider Complex Carbohydrates: Foods that are high in fiber, like whole grains, can provide energy without causing a rapid spike in blood sugar.
-
Consult with Specialists:
- Work with an Allergist: Since you have MCAS, collaborating with an allergist who is familiar with this condition may provide additional insights. They might suggest specific foods to avoid or strategies to reduce mast cell activation.
- Discuss with a Dietitian: A registered dietitian familiar with MCAS can help tailor your diet to minimize symptoms while ensuring nutritional adequacy.
-
Symptom Management:
- Preemptive Antihistamines: Speak with your healthcare provider about the possibility of taking antihistamines before consuming sugary foods as a preventive measure.
-
Immediate Response Plan:
- Stay Hydrated: If you experience symptoms, make sure to drink plenty of water to help your body manage the reaction.
- Cool Down: If you feel flushed or feverish, using a cool cloth on your forehead and neck can help ease the discomfort.
Reassurance
It’s completely understandable to feel anxious about unusual bodily reactions. You're not alone in experiencing food-related symptoms, and with careful monitoring and dietary adjustments, you may find relief. Keeping open communication with your healthcare team will be key to understanding and managing your reactions effectively. If you have more questions or need further support, feel free to ask.

Sudden Fever and Rapid Recovery: A Health Query
**Age**: 28 **Gender**: Male **Height**: 177 cm **Weight**: 85 kg **Ethnicity**: Caucasian **Duration of Symptoms**: A few hours **Location**: Denmark **Pre-existing Medical Conditions**: None **Current Medications**: None Hello, Earlier today, around 4 PM, I began to feel unwell, as if I was coming down with a fever. I was lying on the couch wrapped in layers of clothing, yet I started to feel increasingly cold. To warm up, I moved to my bed, but as I undressed to get comfortable, I was shaking uncontrollably. I attempted to warm myself, but my efforts were futile. Approximately 30 minutes after getting into bed, I realized I needed to take some ibuprofen. However, the walk to the bathroom made me feel even colder and intensify my shivering. I spent the time in bed focusing on reducing my shivers and trying to prevent the chill. About 45 minutes post-medication, the shaking subsided, but I still felt quite unwell. Eventually, I managed to doze off, and after about half an hour, I woke up feeling completely normal. This was around 6:30 PM. Now, at 9:30 PM, I can barely recall having had a fever, though it felt very intense while it lasted. I haven't had a fever of that severity in quite some time. Here's my concern: I've been dealing with a mildly infected wisdom tooth for the past few days. It seemed to peak two days ago but has been less painful since yesterday, and today I hardly feel it aside from some swelling. Should I reach out to a doctor, or do you think I will be okay? I’m just a bit perplexed by how quickly my condition changed from feeling very sick to completely fine. If my wisdom tooth had been giving me more trouble today alongside the fever, I would have sought medical advice immediately, but since the pain has lessened, I'm unsure. Thanks for your guidance!
Persistent Fevers and Lymphadenopathy Concerns
Greetings! I’m a 21-year-old female living with POTS, yet over the last year, I've experienced some increasingly unusual symptoms that I would like to highlight: - Five lymph nodes that feel rubbery and are approximately the size of grapes - Daily fevers fluctuating between 101 and 102°F - Noticeable weight loss along with a diminished appetite (this has escalated recently, leading to a loss of about 3 pounds weekly) - Appearance of purple spots on my leg - Presence of eosinophilia as well as ovalocytes and monocytes in my blood tests - Significant fatigue coupled with shortness of breath - Severe episodes of sweating, both during the night and throughout the day, that seem to appear sporadically I have already undergone evaluations that ruled out heart diseases, infections, parasitic infections, and most autoimmune disorders. Any insights or experiences related to these symptoms would be greatly appreciated!
Is It Time to Consult My Doctor?
I've been unwell for the past ten days, experiencing a combination of fever, persistent cough, nasal and chest congestion, along with a sore throat. Initially, my fever was quite mild, and I felt I was on the mend toward the end of last week. However, my condition suddenly worsened, with the cough and nasal congestion becoming much more severe. Currently, my fever remains elevated between 102 and 103 degrees, despite taking medications. While I have noticed a slight improvement in my cough, the sinus issues have escalated to the worst I've ever encountered. I’m experiencing pain in my face and a continual brown discharge from one nostril. I’m fairly confident that pneumonia is not the issue here, and the majority of my symptoms are typically linked to viral infections. So, I question the necessity of scheduling a visit with my doctor. I am a 31-year-old woman, not on any medications, with no significant health issues. My height is 5'10" and I weigh 138 pounds, residing in the United States.
I've Been Experiencing a Fever for Three Days—What Should I Do?
(M16) Let me provide you with a detailed account of my recent health issue. On Sunday, I woke up with an intense headache. My father, who tends to be quite protective and easily anxious, suggested that I check my temperature. It registered at 37.1°C. Moving to Monday, I experienced several bouts of sweating throughout the night. When morning arrived, my headache persisted. I took my temperature again, and it had risen to 37.7°C. Last night, the sweating episodes continued, and I found it quite unpleasant. This Tuesday morning, my headache was still bothering me, so I measured my temperature once more—this time, it peaked at 38.7°C. Consequently, I decided to skip school today. I had also left early the previous day. Every time I change position—whether I stand, sit, bend, or lean—I feel an intensification of the headache, but thankfully, it only lasts for a brief moment. As I write this at 8:15 PM, I’m quite apprehensive about facing another night of waking up drenched in sweat. Can anyone provide some guidance on what steps I should take?
Is Food Poisoning Improving or Getting Worse?
Greetings, everyone. I'm a 22-year-old female, and I wanted to share my experience with a recent health issue. Last Thursday night, as I was preparing to go to sleep, I suddenly experienced uncontrollable shivers and then woke up early Friday to vomit. Throughout Friday, I dealt with a significant fever reaching 38.7°C, along with diarrhea, intense body aches, and stiffness in my neck. By Friday night, I had no choice but to call for an ambulance. The medical team administered a shot that helped reduce my fever, allowing me to get some restful sleep. By Saturday, I had started to feel a bit better, but the diarrhea seemed to escalate, leading me to the bathroom every ten minutes. At one point, it was nearly just water. Due to signs of dehydration, I went to the emergency room where I received intravenous fluids. The doctor, from a clinic in the Southern Caucasus, prescribed me a regimen including smecta, brefovil sachets, and a probiotic, each in specified doses for a duration of five days. As I'm writing this on Tuesday, it's now been three days since I began taking these medications. On Sunday, I felt significantly improved, with all my symptoms subsided—I didn't need to visit the restroom at all that day. By Monday morning, my stool returned to normal, and once again, I was symptom-free. However, around 5 PM on Monday afternoon, the diarrhea returned, although not as severe as before; it was less watery and not occurring as frequently. This issue recurred around 1 AM today and has continued intermittently throughout the day since then. Is it common for diarrhea to return during recovery? I'm starting to worry because this past week has been emotionally draining, particularly with my family located in another country. The thought of reliving this ordeal alone is quite distressing for me. Financially, I've already spent a considerable amount on medical care and can’t afford another visit until payday in a few days, so I would greatly appreciate any advice or insight you could provide. For what it's worth, my diet has mainly consisted of rice, mashed potatoes, and baby food over the past few days.
