Your Wegovy tablets first month sets the pattern for everything that follows. Your body adjusts to two things at once: the medicine itself, and eating differently. Most of what feels new is expected. It isn't a sign something is wrong.

This guide covers what a typical first month looks like. It covers what helps, and what genuinely needs medical attention rather than patience.

Everyone adjusts at a different pace. Use this as a general guide, not a strict timetable for your own experience.

What Wegovy tablets are for

Wegovy tablets contain semaglutide, prescribed for weight management alongside a reduced-calorie diet and increased physical activity. They reduce appetite. They also slow how quickly your stomach empties.

Your prescriber decides whether this treatment suits you. That decision rests on your overall health, current weight, and any other conditions you live with. The NHS's information on semaglutide is a useful general reference alongside your own Patient Information Leaflet.

Why treatment starts at a low dose

Treatment begins at the lowest strength. It increases gradually over several weeks. This isn't caution for its own sake. The lower doses let your body adjust before a higher dose arrives.

Taking more than prescribed doesn't get you to your goal faster. It mainly increases side effects without adding any benefit. Our guide to the four Wegovy dose strengths explains why each step is spaced out the way it is.

How to take your tablet correctly

Take your tablet on an empty stomach, first thing works well for most people. Wait around 30 minutes before eating, drinking anything other than a small amount of plain water, or taking other oral medicines.

Swallow it whole with a sip of water. Don't crush, split or chew it, since this changes how the medicine is absorbed. Try to take it at roughly the same time each day. If you eat or drink too soon afterwards, the dose may not work as intended, so your prescriber may advise waiting for the next scheduled dose rather than taking an extra one. Getting this small routine right from day one makes the rest of your Wegovy tablets first month easier to settle into.

Before your first dose

A little preparation in the days before you start makes the first week easier.

It helps to:

read your Patient Information Leaflet in full before you start
keep your first week or two free of big meals out
stock simple, easy-to-tolerate food such as plain proteins, vegetables and soup
tell your prescriber about any other medicines or supplements you take
keep a simple note of how you feel each day

Telling the people you live with

A little context for the people around you helps more than staying quiet about it. Family or housemates who know you're adjusting to a new medicine tend to understand mood dips, appetite changes, or an early night without needing an explanation each time.

You don't need to share every detail, just enough that odd moments make sense. This matters especially at shared mealtimes, since a smaller portion or a skipped course can otherwise look like nothing. Some people find it easier to keep hydration and food routines on track when someone else in the house knows what's going on and can gently remind them. Deciding how much to share is entirely personal, and there's no requirement either way.

Week one

Most people notice a drop in appetite within the first few days. Smaller portions start to feel like enough. Snacking between meals loses its appeal.

Mild nausea is common in week one, especially after eating too much or too quickly. It usually settles as the week goes on. Some people also feel a little more tired than usual, or slightly more prone to headaches.

If nausea continues well beyond the first couple of weeks, read our guide on managing nausea and appetite changes early on. It goes into more detail than we can here.

Week two

Nausea usually settles further in week two. Cravings and habit-driven eating can become the more noticeable challenge instead. Reaching for food out of routine, rather than hunger, is a different problem to nausea. Name it rather than mistaking it for a lapse in willpower.

Weeks three and four

By week three, eating patterns generally feel more established. Portions that felt small in week one start to feel normal. Energy levels typically pick back up as hydration and meal timing settle.

By week four, you can usually judge whether appetite and portion size feel genuinely different. That's a more useful marker this early than the number on the scale.

Side effects beyond nausea

Nausea gets most of the attention. It isn't the only thing people notice in the first month. Other effects commonly reported early on include:

headaches, particularly in the first week or two
constipation, or less often looser stools
mild fatigue
feeling light-headed when standing up quickly

None of these are a reason to stop treatment on their own. Mention it to your prescriber if any of them are severe, persistent, or getting worse rather than better.

Eating in the first month

Smaller, simpler meals sit better than large or rich ones while your body adjusts. Eat slowly. Stop when you feel satisfied. This helps more than any specific food rule.

Fatty or very rich meals are the most likely to trigger nausea early on. Protein and vegetables tend to sit better than heavy or greasy food. Eating something small keeps nausea more manageable than skipping meals altogether. The British Nutrition Foundation's eating-well guidance is a reasonable general reference alongside your prescriber's advice.

Staying hydrated

Reduced food intake can mean reduced fluid intake too, especially in the first couple of weeks. If nausea puts you off drinking, take small sips through the day rather than trying to catch up all at once.

A dry mouth, dark urine, or feeling light-headed when you stand up are signs you're not drinking enough. Address any of these straight away.

Movement in month one

Wegovy tablets are prescribed alongside increased physical activity. The first month still isn't the time to start anything intense.

Walking more, taking the stairs, generally moving a little more than before is a realistic starting point. Starting a demanding new exercise routine in week one, on top of eating less and a body still adjusting to the medicine, is a common reason people feel worse than they need to.

Fitting your first month around work

Meetings, commutes and a normal working day don't pause while your body adjusts. Keep simple snacks nearby in case appetite dips unpredictably rather than at planned mealtimes.

A small bottle of water at your desk helps you keep sipping through the day without thinking about it. If nausea tends to appear after eating, avoid scheduling a heavy lunch right before something demanding, such as a long meeting or a drive. Mornings are often easier than afternoons in the first couple of weeks, so save anything more physically demanding for earlier in the day where you can choose. None of this needs to be obvious to colleagues. Small, practical adjustments are usually enough to get through a normal working week while you adjust.

Other medicines and supplements to disclose

Tell your prescriber about everything you take, not just regular prescriptions. This includes over-the-counter painkillers, vitamins, herbal supplements and anything taken only occasionally.

Some oral medicines are absorbed differently once your stomach empties more slowly, a normal effect of Wegovy tablets rather than a problem with the other medicine. Your prescriber can advise on timing if this applies to something you take regularly. Leaving anything out, even something that seems minor, makes it harder for your prescriber to give accurate guidance, and it slows down future dose reviews too.

If you're managing another condition too

Weight loss doesn't happen in isolation from everything else going on with your health. If you're also living with PCOS, your first month can look different from general advice. Insulin resistance in particular can slow the pace without anything being wrong.

Cholesterol and blood pressure can both shift as your weight changes. Our articles on weight loss and high cholesterol and weight loss and blood pressure cover what tends to change first.

Common misunderstandings about starting treatment

A few misconceptions come up often enough in the first month to address directly.

Nausea is a side effect of your body adjusting. It isn't a sign the medicine is working better. Plenty of people see good results with very little nausea. The goal is smaller, appropriate portions, not eating as little as possible. Under-eating can make nausea and fatigue worse, not better.

For most people, the first week or two is the most noticeable adjustment period. Things tend to settle from there. Gentle movement is enough in month one. There's no need to start an intense exercise routine straight away. Our article on common weight loss myths covers other misconceptions worth knowing before you start.

Your Wegovy tablets first month: what "working" looks like

Weight change in the first month varies a lot between people. A smaller number than you hoped for isn't a sign anything is wrong. The dose is still low at this stage on purpose.

A more useful sign at four weeks is whether appetite and portion size feel genuinely different, not just the number on the scale. Try not to compare your first month with anyone else's. Response varies. A slower start doesn't predict a worse outcome later.

Troubleshooting a difficult first month

Not every first month goes smoothly, and that's worth normalising. If nausea feels worse than expected, revisit the eating and hydration guidance above before assuming something is wrong.

If you missed a tablet because a bad day threw off your routine, follow the guidance in your Patient Information Leaflet rather than guessing, and don't double up to compensate. If travel, illness or a busy week disrupted your usual pattern, mention it at your next check-in so your prescriber has the full picture rather than an incomplete one. A first month that felt harder than expected doesn't predict how the rest of treatment will go.

When to contact your prescriber

Mild nausea or reduced appetite is expected. Persistent vomiting and an inability to keep fluids down are not. Severe abdominal pain, particularly pain spreading to your back, needs prompt medical attention too, since it can rarely indicate pancreatitis.

Raise it promptly rather than waiting for your next review if you notice severe constipation that doesn't respond to normal measures, signs of dehydration that don't improve once you increase fluids, or any symptom that feels distinctly different from the adjustment effects above.

Frequently Asked Questions

Is nausea in the first week normal?

Yes, commonly, and it usually eases as your dose stabilises.

Will my appetite come back?

Reduced appetite is the medicine working as intended, not a side effect to push through by eating more than you want to.

What if I'm still hungry?

Eat. The goal is smaller, appropriate portions, not going without.

How long until my dose changes?

Your prescriber plans titration and reviews it against how you're tolerating treatment, not on a fixed date.

Do I need to change my diet completely in month one?

No. The medicine supports change. It doesn't require an overhaul on day one.

Can I exercise normally in the first month?

Gentle movement is fine and encouraged, but this isn't the month to start an intense new routine.

What if I feel dizzy after standing up quickly?

It's usually linked to reduced food and fluid intake rather than the medicine itself. Make sure you're drinking enough.

Should I weigh myself every day?

Weekly is usually more useful than daily. Day-to-day weight naturally fluctuates.

Can I drink alcohol during my first month?

Our dedicated guide on drinking alcohol while taking Wegovy covers this in full.

What should I do if I miss a dose in month one?

Follow the guidance in your Patient Information Leaflet rather than guessing. Don't take an extra dose to make up for it.

What should I do if I forget whether I took today's tablet?

Don't take a second one to be safe. Follow the missed-dose guidance in your Patient Information Leaflet instead.
