What the first weeks usually feel like
Most of what I hear in the first weeks on semaglutide or tirzepatide
is undramatic, and that is the honest place to start, because the
internet makes the beginning sound much worse than the version that
walks into my office. Both are once-weekly injections, and we start at
a low dose and raise it gradually, which the program does for a
reason: the common side effects, nausea, diarrhea and a smaller
appetite, are easier to live with when the dose climbs slowly.
What I see is a pattern rather than a crisis. Appetite drops,
sometimes inside the first week, and people are surprised by how early
that happens. Nausea, when it shows up, tends to arrive in the day or
two after an injection and then ease off. Some people feel full after
a few bites and stop eating halfway through a plate without ever
deciding to. Those are the reports. The check-ins in the first weeks
sit close together for exactly this reason, and I would rather see
someone twice for a quiet week than once for a bad one. The reasons
behind the reports come later in this piece, and I will say plainly
which part is a guess.
Why I keep the report separate from the explanation
In the emergency department I never read faces. I worked from the
chief complaint, the vital signs and the questions I asked about the
pain, and I have kept that habit because it protects a client from my
own assumptions. So at a follow-up I keep two columns in my head. One
is what you report and what I can check: how often you were nauseated,
whether you kept fluids down, your weight on our scale, how the
injection sites look. The other column is my explanation, and I label
it as exactly that.
Here is the explanation, labeled. These medications mimic a hormone
your body releases after you eat, which reduces hunger, increases
fullness and helps regulate blood sugar. My working idea about the
early nausea is that the gut is adjusting to that signal and the
gradual dose increases give it time. That idea could be wrong for a
given person, which is why the plan changes when the report changes,
and never just because the explanation sounded good to me.
Understanding GLP-1: Side Effects
Nausea: what helps and what does not
The clients who do best with nausea eat smaller amounts more often and
stop when they feel full, instead of finishing the plate out of habit.
Heavy, greasy meals tend to sit badly in the first weeks, so I ask
people to notice which meals land fine and which do not, rather than
follow a rigid list from me that was written for someone else’s
stomach. Electrolytes also help a ton with nausea; we recommend
zero-sugar LMNT.
What does not help is pushing through. If nausea was bad enough that
you skipped meals for two days, I want that report before the next
injection goes in, while there is still time to do something useful
with it. Dose adjustments are part of a supervised program, and
holding a dose where it is for another week or two is a normal tool in
that program. Nobody is behind for needing it.
Water first
A smaller appetite and nausea together mean people drink less without
noticing, because a lot of our fluid comes with meals and the meals
have shrunk. Diarrhea, when it happens, pulls fluid in the other
direction. So the first thing I ask about at an early follow-up is
water, and the scale comes after.
I ask people to keep a bottle in sight and sip through the day rather
than try to catch up at night, and broth, milk and the fluid in yogurt
and fruit all count toward it. If plain water is not staying
appealing, zero-sugar electrolytes can be added to it. Dizziness when
you stand, a headache that lingers, dark urine and a dry mouth are the
signs I hear about when fluids have slipped, and I would much rather
hear about them in a message than discover them at the visit.
Protein when you are eating less
Once the appetite drops, the question changes from how much to what.
When the total shrinks, I want protein to be the part that stays. In
practice that means protein first at each meal, eggs, chicken, fish,
yogurt, beans, before the bread or the fruit, so that if you are full
after a few bites the protein has already gone in.
The lifestyle coaching the practice pairs with the medication is built
for this stage. I would rather spend part of a follow-up looking at
what three days of meals actually looked like than hand over a generic
plan, because the generic plan assumes an appetite you may no longer
have.
When to call before your next dose
Call or message if you cannot keep fluids down, if vomiting goes past
a day, if you have severe or persistent belly pain, if you have the
dehydration signs above, or if something feels wrong to you even when
you cannot name it. Those are plain reasons to be seen, and your
provider should hear them before your next injection goes in.
Call for the quieter things too: an injection site that worries you,
nausea that is turning you off food entirely, or a week that was much
harder than the one before it. Side effect management is a stated part
of a supervised program, and it only works if the report reaches us.
One more thing I ask every new client to do: if you are unsure whether
to take the next injection because of how the week went, ask first. A
dose held for a few days while we talk is easy to come back from, and
the conversation usually takes five minutes.
What a follow-up is actually for
Before anyone starts, the consultation reviews medical history and
runs labs, and only candidates are started. After that, the regular
check-ins are where the medication gets managed: the dose adjusted,
side effects handled, and the eating plan changed as the appetite
changes. That is the structure at the Knoxville clinic that runs the
program (https://weightlossknoxvilletn.com/), which is one of my other
businesses at the same two offices in Bearden and Farragut.
The room where this happens is plain: white walls, a treatment chair,
a rolling tray, a scale. There is nothing in it that will tell me how
your week went, so the visit depends on what you bring to it, and I
have learned to ask for the boring details first. That is also how
GLP-1 care in Knoxville (https://hitchcoxaesthetics.com/weight-loss)
works at my aesthetics practice, since the same supervised program
sits behind both doors.
I do not know in advance which clients will sail through the first
month and which will need a slower climb. What I can promise is that
we will look at what actually happened, keep the explanation in its
own column, and adjust from the report. The first weeks are where that
habit earns its keep.
