Is Rapid Weight Loss Causing My Constant Hunger and Cravings? - #24663

Naffre

Hello, I'd like to know if losing weight quickly (for me, 3 kg in about a week) or after restricting my diet can lead to intense, almost constant hunger throughout the day, almost painful, felt above the navel. (This is amplified after meals or on an empty stomach with strong sugar cravings.) Because this has been happening to me since I lost weight, and it's been going on for a month. (Before, I weighed 63 kg at 1.80 m tall, and now I weigh around 59.5-60 kg). Is this related, or not at all? Thank you for your answers.

How long have you been experiencing these hunger symptoms?:

- 1-2 months

What type of diet have you been following?:

- Balanced diet

Have you noticed any other symptoms related to your digestive health?:

- Nausea

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

Yes — very likely related.

Losing 3 kg in one week at your height (1.80 m, now ~60 kg) is rapid, and your BMI is already on the lean side. When weight drops quickly, your body reacts by:

Increasing ghrelin (hunger hormone)

Lowering leptin (satiety hormone)

Increasing cravings, especially for sugar

Causing strong “empty” or gnawing pain above the navel

This can last weeks to months after dieting.

The nausea + pain above the navel may also suggest: Gastritis Acid reflux Stomach irritation from restriction

Important:

At 59–60 kg and 1.80 m, you are borderline underweight. Your body may simply be trying to regain lost weight.

What helps: Eat regular meals (every 3–4 hours) Include protein + healthy fats in each meal Avoid long fasting periods Do not restrict calories further

If pain is persistent or severe, consider checking:

H. pylori test Basic labs (CBC, iron)

But overall — this sounds like a normal biological rebound from rapid weight loss, not something dangerous.

I trust this helps Thank you Take care

Yes — very likely related.

Rapid weight loss and restriction can cause: Blood sugar swings → mood changes Low energy intake → fatigue, weakness Hormonal stress response

At your current weight, your body may still feel in a deficit.

What helps: Eat every 3–4 hours Increase calories slightly (protein + healthy fats + complex carbs) Sleep well Avoid over-exercising

If fatigue continues, check iron, B12, and thyroid. Most symptoms improve once nutrition stabilizes.

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.

losing weight quickly and restricting your diet can absolutely cause intense, constant hunger like you’re describing, and it is very likely related.

When you lose weight rapidly (3 kg in a week) or reduce calories, your body goes into a “survival/compensation mode.” Hormones change:

• Ghrelin (hunger hormone) increases strongly • Leptin (fullness hormone) decreases • Blood sugar may fluctuate → strong sugar cravings, shaky/empty feeling, nausea • Stomach acid can increase → burning or painful hunger above the navel

Because your current weight (~59–60 kg at 1.80 m) puts your BMI around 18–18.5 (borderline underweight), your body is likely trying to push you to eat more to restore weight, which explains:

constant hunger even after meals • painful empty sensation • sweet cravings • symptoms worse on empty stomach • nausea or stomach discomfort

This is very common after calorie restriction or being slightly underweight, not usually a dangerous disease.

What you should do: • Increase calories gradually (add 300–500 kcal/day) • Eat small frequent meals every 3–4 hours • Include protein + healthy fats (eggs, nuts, yogurt, peanut butter, rice, potatoes) • Avoid long fasting gaps • Stay hydrated

I’ve already done it, everything is OK

Rapid weight loss can indeed trigger intense hunger and sugar cravings, which your body is experiencing as a natural response to the significant calorie deficit or changes it’s detecting. When you lose weight quickly, especially by restricting your diet, your body might react by increasing levels of ghrelin, the “hunger hormone,” which tends to push you towards eating more. This is its way of trying to restore energy balance. Losing around 3 kg in a week might have disrupted your body’s homeostasis, and it may be trying to persuade you to consume more calories to get back to its previous state. This feeling of hunger, especially if it’s almost painful above the navel, could also be linked to your stomach producing more gastric juices or an empty stomach leading to discomfort. Sugar cravings often follow this cycle because simple carbohydrates offer quick energy, which your body craves when it’s undernourished.

Maintaining a balance is key, and you may need to reassess how you’re going about your weight loss. Gradual weight loss — no more than 0.5-1 kg per week — is generally more sustainable and less likely to lead to these intense hunger pangs. Also, ensure your diet isn’t just low in calories but rich in nutrients. Focus on whole foods that will fill you up more effectively, like fiber-rich vegetables, lean proteins, and healthy fats, which can promote satiety. Incorporating protein in every meal can help modulate hunger.

If the hunger persists or you notice any other troubling symptoms, consult with a healthcare provider to exclude any underlying conditions like hyperthyroidism or gastrointestinal issues that might be contributing. And ensure you’re not misinterpreting thirst for hunger – drinking enough water throughout the day can sometimes help manage hunger cues. User-centered, practical advice would focus on these aspects and encourage listening to your body’s needs more than strictly adhering to any rapid diet changes. If your symptoms are interrupting your regular life excessively or don’t improve with dietary adjustments, do seek further evaluation. Nutritional guidance can provide a more tailored approach in-house if needed.

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 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.

Hello Absolutely, what you’re describing is very common after rapid weight loss or strict dieting. Here’s why:

Why You’re Feeling Intense Hunger

When you lose weight quickly—especially by restricting calories—your body’s natural response is to increase hunger signals. This is a survival mechanism. Hormones like ghrelin (the “hunger hormone”) rise, making you feel hungrier, sometimes even painfully so. This hunger is often strongest above the navel (upper abdomen), and cravings for sugar or carbs are especially common.

After meals, your body may still feel unsatisfied because it’s trying to restore the energy (and sometimes nutrients) it lost. This can make hunger feel almost constant, even if you’re eating enough by the numbers.

*Is This Related to Your Weight Loss?*Yes, it’s directly related. Rapid weight loss and calorie restriction can: - Increase hunger hormones - Slow down metabolism - Cause cravings, especially for high-energy foods (like sweets or carbs) - Sometimes cause mild stomach discomfort or “hunger pangs” above the navel

What Can Help? - Eat balanced meals: Include protein, healthy fats, and fiber to help you feel full longer. - Don’t skip meals: Skipping meals can make hunger and cravings worse. - Avoid very low-calorie diets: Gradual weight loss is easier for your body to handle. - Stay hydrated: Sometimes thirst feels like hunger. - Consider a check-up: If hunger is extreme, persistent, or you have other symptoms (like weakness, dizziness, or digestive issues), see a doctor to rule out other causes (like thyroid or blood sugar problems).

In summary:
Your symptoms are a normal response to rapid weight loss and diet restriction. Your body is asking for more energy. If you want, I can suggest ways to manage hunger and maintain a healthy weight without feeling miserable.

Thank you

I'm Dr. Alan Reji, a general dentist with a deep-rooted passion for helping people achieve lasting oral health while making dental visits feel less intimidating. I graduated from Pushpagiri College of Dental Sciences (batch of 2018), and ever since, I've been committed to offering high-quality care that balances both advanced clinical knowledge and genuine compassion for my patients. Starting Dent To Smile here in Palakkad wasn’t just about opening a clinic—it was really about creating a space where people feel relaxed the moment they walk in. Dental care can feel cold or overly clinical, and I’ve always wanted to change that. So I focused on making it warm, easygoing, and centered completely around you. I mix new-age tech with some good old-fashioned values—really listening, explaining stuff without jargon, and making sure you feel involved, not just treated. From regular cleanings to fillings or even cosmetic work, I try my best to keep things smooth and stress-free. No hidden steps. No last-minute surprises. I have a strong interest in patient education and preventive dentistry. I genuinely believe most dental issues can be caught early—or even avoided—when patients are given the right information at the right time. That’s why I take time to talk, not just treat. Helping people understand why something’s happening is as important to me as treating what’s happening. At my practice, I’ve made it a point to stay current with the latest innovations—digital diagnostics, minimally invasive techniques, and smart scheduling that respects people’s time. I also try to make my services accessible and affordable, because good dental care shouldn’t be out of reach for anyone.

Yes — rapid weight loss or strict diet restriction can cause intense hunger, because your body increases hunger hormones (like ghrelin) and slows metabolism to restore lost weight. However, persistent painful hunger above the navel, strong sugar cravings, and nausea can also suggest stomach irritation, gastritis, acid-related problems, or blood sugar fluctuations, not just dieting effects. Since symptoms have lasted a month, please consult a physician or gastroenterologist for evaluation and advice on safe nutrition and stomach health.

Thank you for your reply, but the hunger doesn’t go away even with Nexium. Perhaps it just needs more time?

Regarding the blood sugar fluctuations, what causes them and what can be done about them?

(I already saw a gastroenterologist, but he couldn’t tell me what was causing this hunger and said I don’t seem to have anything wrong with me.)
