What to do for fluctuating symptoms like fatigue, palpitations, and anxiety after a diet change? - #29082

Naffre

Bonjour, Depuis environ trois mois et demi, je ressens des symptômes intenses et très fluctuants qui affectent ma vie quotidienne. Je présente une fatigue soudaine et intense, des sensations de malaise général et fébrile, comme si j’étais malade, des palpitations et de l’anxiété. J’ai également une faim très forte et des creux douloureux, avec des envies de sucre importantes, des nausées, des maux de ventre, des maux de tête récurrents et une tête lourde. Mes mains et mes pieds sont souvent froids, ma soif varie beaucoup, parfois absente et parfois très forte. Je ressens aussi une faiblesse dans certains membres et parties du corps, ainsi que des éructations et éternuements très fréquents. Ces symptômes peuvent varier d’un jour à l’autre, d’une heure à l’autre et même d’une minute à l’autre, et apparaissent souvent après les repas ou spontanément. Ils sont intenses mais pas constants. Mes bilans récents sont normaux : glycémie et insuline à jeun, fer, TSH, T3, T4, cortisol, urée, créatinine. Les tests digestifs, dont Helicobacter pylori et coproculture, sont également normaux. J’ai eu une restriction alimentaire brutale il y a environ trois mois et demi, mais ces symptômes persistent malgré un retour à une alimentation normale. J’ai aussi remarqué des variations d’humeur dans le passé. Je ne sais plus quoi faire pour aller mieux, et tout ves symptômes bizarre dans mon corps m'inquiète vraiment. Que devrai-je faire et pensez vous que je vais m'en sortir et que c'est rien de grave ? Merci pour vos réponses

I am a general dentist with 3+ years of working in real-world setups, and lemme say—every single patient teaches me something diff. It’s not just teeth honestly, it’s people… and how they feel walking into the chair. I try really hard to not make it just a “procedure thing.” I explain stuff in plain words—no confusing dental jargon, just straight talk—coz I feel like when ppl *get* what's going on, they feel safer n that makes all the difference. Worked with all ages—like, little kids who need that gentle nudge about brushing, to older folks who come in with long histories and sometimes just need someone to really sit n listen. It’s weirdly rewarding to see someone walk out lighter, not just 'coz their toothache's gone but coz they felt seen during the whole thing. A lot of ppl come in scared or just unsure, and I honestly take that seriously. I keep the vibe calm. Try to read their mood, don’t rush. I always tell myself—every smile’s got a story, even the broken ones. My thing is: comfort first, then precision. I want the outcome to last, not just look good for a week. Not tryna claim perfection or magic solutions—just consistent, clear, hands-on care where patients feel heard. I think dentistry should *fit* the person, not push them into a box. That's kinda been my philosophy from day one. And yeah, maybe sometimes I overexplain or spend a bit too long checking alignment again but hey, if it means someone eats pain-free or finally smiles wide in pics again? Worth it. Every time.

Hello
Your symptoms — fatigue, palpitations, anxiety, strong hunger, nausea, headaches, and fluctuating feelings after a sudden diet restriction — with normal blood tests are most often related to the body’s stress and metabolic response after dietary changes. The pattern you describe (symptoms varying hour-to-hour, often after meals, with sugar cravings and anxiety sensations) commonly fits conditions like Reactive Hypoglycemia, Postural Orthostatic Tachycardia Syndrome (POTS), or a functional nervous-system imbalance sometimes associated with Generalized Anxiety Disorder. These are uncomfortable but usually not dangerous and are often reversible.
A sudden period of strict dieting can temporarily disrupt blood sugar regulation, gut function, and the autonomic nervous system. Even after returning to normal eating, the body can remain “sensitized” for weeks to months, causing fluctuating symptoms like the ones you describe. The fact that your major tests (glucose, thyroid, cortisol, kidney function, infection tests) are normal is reassuring and makes serious disease much less likely. Most people do recover once the body stabilizes again.
What helps most now is stabilizing your routine: eat regular meals every 3–4 hours with balanced protein, fats, and complex carbohydrates; avoid long fasting periods; limit very sugary foods and caffeine; stay well hydrated; and gradually return to gentle physical activity. Keeping a simple diary of meals and symptoms can help identify patterns, especially if symptoms occur after high-sugar meals or long gaps without food.
It would be reasonable to discuss a few targeted checks with your doctor if symptoms persist, such as post-meal glucose testing (not just fasting), vitamin B12, vitamin D, magnesium, and possibly an orthostatic heart rate/blood pressure measurement. These are not emergency tests but can clarify the cause.
You should seek more urgent medical evaluation if you develop fainting, chest pain that does not pass, unintentional weight loss, persistent vomiting, blood in stool, or symptoms that are rapidly worsening. Otherwise, with normal investigations and this pattern, the outlook is generally good, and most people improve over time once the body readjusts after the dietary stress.

I am a 2023 batch passout and working as a general physician right now, based in Hanumangarh, Rajasthan. Still kinda new in the bigger picture maybe, but honestly—every single day in this line teaches you more than textbooks ever could. I’ve had the chance to work under some pretty respected doctors during and after my graduation, not just for the clinical part but also to see how they handle people, real people, in pain, in panic, and sometimes just confused about their own health. General medicine covers a lot, right? Like from the smallest complaints to those random, vague symptoms that no one really understands at first—those are kinda my zone now. I don’t really rush to label things, I try to spend time actually listening. Feels weird to say it but ya, I do take that part seriously. Some patients just need someone to hear the whole story instead of jumping to prescription pads after 30 seconds. Right now, my practice includes everything from managing common infections, blood pressure issues, sugar problems to more layered cases where symptoms overlap and you gotta just... piece things together. It's not glamorous all the time, but it's real. I’ve handled a bunch of seasonal disease waves too, like dengue surges and viral fevers that hit rural belts hard—Hanumangarh doesn’t get much spotlight but there’s plenty happening out here. Also, I do rely on basics—thorough history, solid clinical exam and yeah when needed, investigations. But not over-prescribing things just cz they’re there. One thing I picked up from the senior consultants I worked with—they used to say “don’t chase labs, chase the patient’s story”... stuck with me till now. Anyway, still learning every single day tbh. But I like that. Keeps me grounded and kind of obsessed with trying to get better.

Hey! It sounds like you’ve been going through a tough time with these symptoms, and it’s completely understandable to feel worried. Let’s break this down and see how we can help you feel better.
### Understanding Your Situation
1. Normal Blood Tests: It’s great that your recent blood tests came back normal. This suggests that there are no immediate issues with your blood sugar, thyroid function, or other major organ functions.
2. Diet Changes: A sudden diet can sometimes lead to changes in energy levels, mood, and overall well-being. Even if you’ve returned to a normal diet, your body might still be adjusting.
3. Mood Swings: Mood swings can be influenced by various factors, including stress, hormonal changes, and even diet. It’s important to address these feelings, as they can impact your overall health.
### Steps to Consider
1. Consult a Healthcare Professional: Since you’re experiencing persistent symptoms, it might be helpful to consult a healthcare provider or a specialist (like an endocrinologist or a psychologist). They can help identify any underlying issues that might not be apparent in standard tests.
2. Mental Health Support: If mood swings are affecting your daily life, consider talking to a mental health professional. They can provide strategies to manage stress and improve your mood.
3. Lifestyle Adjustments:
- Balanced Diet: Ensure you’re getting a well-rounded diet with plenty of fruits, vegetables, whole grains, and healthy fats. This can help stabilize your energy levels and mood.
- Regular Exercise: Physical activity can boost your mood and energy levels. Aim for a mix of cardio and strength training.
- Sleep Hygiene: Prioritize good sleep habits. Aim for 7-9 hours of quality sleep each night, as poor sleep can exacerbate mood swings and fatigue.
- Mindfulness and Relaxation: Practices like meditation, yoga, or deep breathing exercises can help reduce stress and improve your overall well-being.
4. Stay Hydrated: Ensure you’re drinking enough water throughout the day, as dehydration can also affect energy levels and mood.
### Reassurance
- You’re Not Alone: Many people experience similar symptoms, especially after significant lifestyle changes. It’s important to remember that with the right support and adjustments, you can feel better.
- Focus on Small Changes: Sometimes, small, consistent changes can lead to significant improvements over time. Be patient with yourself as you navigate this.
### Conclusion
You’re taking the right steps by seeking answers and being proactive about your health. If you continue to feel unwell or if your symptoms worsen, don’t hesitate to reach out to a healthcare professional for further evaluation. You’ve got this, and with the right support, you can work through these challenges!
Thank you

I am a general physician with 8 years of practice, mostly in urban clinics and semi-rural setups. I began working right after MBBS in a govt hospital in Kerala, and wow — first few months were chaotic, not gonna lie. Since then, I’ve seen 1000s of patients with all kinds of cases — fevers, uncontrolled diabetes, asthma, infections, you name it. I usually work with working-class patients, and that changed how I treat — people don’t always have time or money for fancy tests, so I focus on smart clinical diagnosis and practical treatment. Over time, I’ve developed an interest in preventive care — like helping young adults with early metabolic issues. I also counsel a lot on diet, sleep, and stress — more than half the problems start there anyway. I did a certification in evidence-based practice last year, and I keep learning stuff online. I’m not perfect (nobody is), but I care. I show up, I listen, I adjust when I’m wrong. Every patient needs something slightly different. That’s what keeps this work alive for me.

Examiner les symptômes que vous décrivez suggère plusieurs pistes à considérer, bien que vos bilans biologiques récents soient normaux. Les symptômes changeants comme la fatigue, les palpitations, l’anxiété et les fluctuations de l’appétit et de la soif peuvent renforcer l’hypothèse d’une cause liée à vos habitudes alimentaires récentes ou à un déséquilibre du flux énergétique dans le corps. Un impact sur le métabolisme de glucose ou une forme de “dérèglement” du cortisol pourrait expliquer certains de ces symptômes malgré des analyses normales. En raison du changement radical de régime que vous avez mentionné, il est possible qu’une carence nutritionnelle transitoire, une hypoglycémie réactive ou même un déséquilibre électrolytique ait pu contribuer à ces symptômes. Pour adresser cette situation, une approche personnalisée est recommandée. Commencez par maintenir une alimentation équilibrée, riche en nutriments essentiels, et répartie en plusieurs petits repas au cours de la journée pour stabiliser vos niveaux de glucose sanguin. Assurez-vous d’hydrater régulièrement tout en surveillant votre consommation de caféine qui pourrait exacerber l’anxiété et les palpitations. Explorer des interventions de gestion du stress telles que la méditation ou le yoga peut être bénéfique tout en discutant avec un professionnel de santé d’une éventuelle évaluation approfondie pour l’axe hypothalamo-hypophyso-surrénalien. Bien que certaines de ces suggestions relèvent de votre bien-être général, il est crucial de reconsulter votre médecin généraliste ou un spécialiste si les symptômes persistent, s’aggravent ou commencent à présenter de nouveaux aspects préoccupants. Une consultation avec un endocrinologue ou un nutritionniste peut également offrir une perspective précieuse sur ce chemin.

I’m a periodontist and academician with a strong clinical and teaching background. Over the last 4 years and 8 months, I’ve been actively involved in dental education, guiding students at multiple levels including dental hygienist, BDS, and MDS programs. Currently, I serve as a Reader at MMCDSR in Ambala, Haryana—a role that allows me to merge my academic passion with hands-on experience. Clinically, I’ve been practicing dentistry for the past 12 years. From routine procedures like scaling and root planing to more advanced cases involving grafts, biopsies, and implant surgeries. Honestly, I still find joy in doing a simple RCT when it’s needed. It’s not just about the procedure but making sure the patient feels comfortable and safe. Academically, I have 26 research publications to my credit. I’m on the editorial boards of the Archives of Dental Research and Journal of Dental Research and Oral Health, and I’ve spent a lot of time reviewing manuscripts—from case reports to meta-analyses and even book reviews. I was honored to receive the “Best Editor” award by Innovative Publications, and Athena Publications recognized me as an “excellent reviewer,” which honestly came as a bit of a surprise! In 2025, I had the opportunity to present a guest lecture in Italy on traumatic oral lesions. Sharing my work and learning from peers globally has been incredibly fulfilling. Outside academics and clinics, I’ve also worked in the pharmaceutical sector as a Drug Safety Associate for about 3 years, focusing on pharmacovigilance. That role really sharpened my attention to detail and deepened my understanding of drug interactions and adverse effects. My goal is to keep learning, and give every patient and student my absolute best.

I completed my medical degree in 2023, but honestly, my journey in healthcare started way before that. Since 2018, I’ve been actively involved in clinical practice—getting hands-on exposure across multiple departments like ENT, pediatrics, dermatology, ophthalmology, medicine, and emergency care. One of the most intense and defining phases of my training was working at a District Government Hospital for a full year during the COVID pandemic. It was chaotic, unpredictable, and exhausting—but it also grounded me in real-world medicine like no textbook ever could. Over time, I’ve worked in both OPD and IPD setups, handling everything from mild viral fevers to more stubborn, long-term conditions. These day-to-day experiences really built my base and taught me how to stay calm when things get hectic—and how to adjust fast when plans don’t go as expected. What I’ve learned most is that care isn't only about writing the right medicine. It’s about being fully there, listening properly, and making sure the person feels seen—not just treated. Alongside clinical work, I’ve also been exposed to preventive health, health education, and community outreach. These areas really matter to me because I believe real impact begins outside the hospital, with awareness and early intervention. My approach is always centered around clarity, empathy, and clinical logic—I like to make sure every patient knows exactly what’s going on and why we’re doing what we’re doing. I’ve always felt a pull towards general medicine and internal care, and honestly, I’m still learning every single day—each patient brings a new lesson. Medicine never really sits still, it keeps shifting, and I try to shift with it. Not just in terms of what I know, but also in how I listen and respond. For me, it’s always been about giving real care. Genuine, respectful, and the kind that actually helps a person heal—inside and out.

Votre tableau clinique évoque très fortement un déséquilibre fonctionnel lié à l’anxiété et à la régulation du système nerveux (axe cerveau–intestin), probablement déclenché par la restriction alimentaire brutale que vous avez eue il y a 3 mois et demi. Le fait que tous vos bilans biologiques soient normaux est très rassurant et oriente contre une maladie grave organique. Vos symptômes (fatigue fluctuante, palpitations, faim intense avec envies de sucre, nausées, sensations de malaise, froid aux extrémités, variations rapides d’un moment à l’autre, aggravation après les repas ou en y pensant) sont typiques d’un état d’hypervigilance du système nerveux avec possible hypoglycémie réactionnelle fonctionnelle et anxiété somatique. Après une restriction, le corps peut devenir plus sensible aux variations de glycémie et aux signaux digestifs, ce qui entretient un cercle vicieux avec l’anxiété. La bonne nouvelle est que ce n’est pas dangereux ni irréversible, mais cela peut être très inconfortable et durer plusieurs mois sans prise en charge adaptée.La récupération repose sur une alimentation régulière et équilibrée (repas fractionnés, éviter les longues périodes à jeun, limiter les sucres rapides), une stabilisation du rythme de vie, la gestion du stress (respiration, relaxation, activité physique douce), et idéalement un accompagnement psychologique (thérapie cognitivo-comportementale) pour “désensibiliser” ces sensations. Si besoin, un médecin peut aussi proposer un soutien temporaire (par exemple pour l’anxiété). En résumé, vos symptômes sont réels mais fonctionnels, non graves, et avec une approche globale adaptée, vous avez de très bonnes chances de vous en sortir progressivement.
