Plain-English answers to the twenty most searched questions about GLP-1 weight treatment — from what food noise really is, to Ozempic vs Wegovy vs Mounjaro, to what the first month actually feels like. Reviewed by Wellora's licensed Thai physicians.
medically reviewed · last updated april 2026GLP-1 (glucagon-like peptide-1) is a hormone your gut naturally releases after you eat. It tells your brain you're full, slows how fast food leaves your stomach, and helps regulate blood sugar.
GLP-1 medications such as Wegovy, Ozempic, Mounjaro and Saxenda are injectable versions of this hormone that keep those signals switched on for longer. The result: reduced appetite, fewer cravings, smaller portions that feel satisfying — and, paired with a sustainable lifestyle, clinical studies show patients lose up to 20% of their body weight.
GLP-1 works in three places at once:
In the brain, it dampens the reward signals that drive impulsive eating — what patients call food noise. In the stomach, it slows gastric emptying so meals feel filling for longer. In the pancreas, it improves insulin sensitivity so blood sugar stays more stable.
This combination is why GLP-1 helps people eat less without feeling deprived — the medication mimics the satiety your body is supposed to produce on its own.
Food noise is the constant mental chatter about food — thinking about the next meal while you're still eating, snack cravings at 3pm, the pull of the pantry after dinner. It's driven by dopamine and hormonal signals that are often stronger in people with obesity.
GLP-1 medications consistently reduce this chatter, usually within the first two to three weeks. It is one of the most reported changes — patients describe feeling mentally free around food for the first time in years.
GLP-1 medications have been prescribed for type-2 diabetes for over 15 years and for obesity since 2014, with extensive long-term safety data.
The most common side effects (nausea, fatigue, constipation) are mild and usually resolve within four to six weeks. Serious side effects are rare but possible — which is why GLP-1 is prescription-only and must be supervised by a licensed physician. A proper metabolic assessment screens for the conditions where GLP-1 is not appropriate.
In most health systems, GLP-1 for weight management is prescribed to adults with a BMI of 27 or higher plus a weight-related condition (such as high blood pressure, pre-diabetes, sleep apnoea or high cholesterol), or a BMI of 30 or higher regardless of other conditions.
A licensed physician makes the final decision after a full medical history, current medications review, and lab work. Pregnancy, personal or family history of certain thyroid cancers, and some pancreatic conditions are contraindications.

start assessment →Ozempic and Wegovy are the same active ingredient — semaglutide — made by the same manufacturer (Novo Nordisk). The difference is the approved use and the dose.
Ozempic is licensed for type-2 diabetes at weekly doses up to 2.0mg. Wegovy is licensed specifically for weight management at weekly doses up to 2.4mg. Clinically, Wegovy produces slightly more weight loss on average because of the higher ceiling dose.
If you are starting GLP-1 purely for weight management, Wegovy is usually the first choice where it is available.
Mounjaro (tirzepatide) and Wegovy (semaglutide) work in related but different ways. Wegovy activates the GLP-1 receptor only. Mounjaro activates GLP-1 plus a second gut-hormone receptor called GIP — which is why it is called a dual agonist.
In head-to-head clinical data, Mounjaro produced about 22% average weight loss at the highest dose vs about 15% for Wegovy. That said, Mounjaro is newer, usually more expensive, and not always available. A physician will match the medication to your history, tolerance and goals — better does not always mean right for you.
Both semaglutide (Ozempic/Wegovy) and tirzepatide (Mounjaro/Zepbound) have excellent long-term safety profiles when prescribed correctly. Side-effect rates are broadly similar — mild nausea, fatigue and digestive upset early on, usually resolving within four to six weeks.
Tirzepatide has a slightly higher reported rate of early-week nausea because of its dual action, but the trade-off is typically faster weight loss. The right choice depends on your metabolic profile, appetite pattern, previous GLP-1 experience, and price considerations — which is what a proper consult is for.
Saxenda (liraglutide) is the original daily GLP-1 for weight management. It is not outdated — it is simply older.
It's now usually considered a second-line option because it requires a daily injection instead of weekly, and average weight loss is lower (around 6–8%) than Wegovy or Mounjaro. Saxenda is still prescribed when the newer options are unavailable, when a patient does not tolerate semaglutide, or in specific clinical circumstances. It has over a decade of safety data behind it.
There is no universal answer. The right medication depends on your current health, previous weight-loss attempts, tolerance to side effects, goals, and what is available and affordable in your country.
A licensed physician reviews your full medical history, labs, current medications and lifestyle before prescribing. At Wellora, that assessment is free — the 90-second online quiz is the first step, followed by a video consult where a Thai-licensed physician makes the actual medical decision with you, not for you.
The first month is almost always the hardest and the most rewarding.
In week one, most patients notice appetite suppression and the quieting of food noise within 48 to 72 hours of the first dose. Mild nausea is common, especially after larger meals. By weeks two and three, the nausea usually settles, hunger stays low, and 2–4 kg of weight loss is typical. Week four often brings a small plateau as the body recalibrates — this is normal, not a failure.
Consistent hydration, high-protein meals and light daily movement make the first month dramatically easier.
Week 1: mild nausea and reduced appetite, occasional fatigue; most common in the first 48 hours after each injection.
Week 2: nausea typically improves; constipation or loose stools may appear.
Week 3: most digestive side effects resolve; you may notice food tastes stronger.
Week 4: a small weight-loss plateau is common; some patients report brief tiredness when moving up to a higher dose.
Months 2–3: most side effects are gone; the main work becomes protein intake, hydration and building movement habits.
Side effects that persist beyond six weeks should always be reviewed by your physician.
The week-four plateau is one of the most common and most misunderstood moments on GLP-1. It happens because your body adjusts water balance and metabolic rate to the new lower weight, and the initial rapid loss settles into a slower, more sustainable pattern. It does not mean the medication has stopped working.
Most patients break the plateau within 7–14 days without changing the dose — especially when they increase protein, drink more water, and add gentle resistance training. A plateau beyond three weeks usually triggers a scheduled dose titration with your doctor.
Weight management is a long-term condition, and most clinical guidelines now treat GLP-1 as a long-term medication — similar to how we treat high blood pressure.
Patients typically stay on a full dose for 12 to 18 months to reach their goal, then work with their physician on a slow, structured taper. Some stay on a maintenance dose long-term. Stopping abruptly almost always causes partial weight regain — this is expected biology, not willpower failure. A good programme plans the taper from day one.
Without structured support, published data shows patients regain roughly two-thirds of lost weight within one year of stopping.
With a supervised taper, strength training to protect lean muscle, and nutrition coaching, that regain is far smaller and many patients maintain their new weight long-term. The most important predictors of maintenance are: a gradual dose taper (not a sudden stop), daily protein at 1.4–1.8 g per kg of target body weight, and 2–3 strength-training sessions per week.
This is why Wellora's programme includes maintenance coaching, not just the injection.
The sticker price is rarely the real price. Here is what patients actually pay for Wegovy-class treatment in the US, EU, Australia, Singapore and Thailand — including the consult fees, platform subscriptions and insurance gaps that most clinics quietly leave out.
About these figures. Prices are approximate retail market rates as of April 2026, for the weight-management dose of semaglutide (Wegovy) or its local equivalent. Individual prices vary by clinic, supply, dose titration and insurance status.
