Supporting Yourself While on a GLP-1
A pharmacist's plain-language companion to Wegovy and Mounjaro: understanding your medication, knowing what to expect, and getting the right support around it.
How GLP-1 medicines actually work
Wegovy (semaglutide) and Mounjaro (tirzepatide) belong to a family of medicines that copy hormones your gut already makes after eating. They gently tell your brain you are full, slow how quickly your stomach empties, and steady your appetite through the day.
That is why people often describe the effect as the food noise going quiet. You are not fighting cravings all day, so it becomes easier to make the changes to eating and activity that carry the results long term. The medicine does part of the work; the habits you build alongside it do the rest.
Starting low and going slow
Both medicines are started at a low dose and increased in steps, usually every four weeks, until you reach the dose that suits you. This is deliberate. A slow ramp is the biggest factor in how comfortable the first few months feel.
If a dose increase feels like a lot, it is completely reasonable to stay where you are for a while longer before stepping up. There is no prize for climbing quickly. Talk to us and we will help you find a pace your body is happy with.
Managing the common side effects
The most common effects are digestive: some nausea, fullness, constipation or occasional reflux, especially in the days after a dose increase. For most people these are mild and settle as the body adjusts.
- Eat smaller portions and stop when you feel comfortably full, not stuffed
- Choose plainer, lower-fat foods on the days you feel queasy
- Sip water steadily through the day to help with both nausea and constipation
- Keep gentle movement in your routine, a short walk after meals helps digestion
Most of these medicines are titrated: you start low and the dose steps up slowly over weeks. That gentle ramp gives your body time to adjust and is the single biggest thing that reduces side effects. Resist the urge to rush it.
Eating well while your appetite changes
When you are eating less, what you eat matters more. Aim to build meals around protein first (eggs, fish, chicken, beans, dairy) and add vegetables and fruit around it. This protects muscle and keeps you steadier between meals.
Hydration slips easily when you are not as hungry, so keep a bottle nearby. If you have specific goals or conditions, a dietitian can tailor this properly, and we are happy to point you in the right direction.
When to check in with us
Most side effects are manageable, but some things are worth a conversation sooner rather than later: severe or lasting tummy pain, repeated vomiting, signs of dehydration, or anything that simply worries you. You never need an appointment to ask.
A calm weekly routine
Pick one day for your injection and keep it the same each week, a phone reminder helps. Store unopened pens in the fridge, keep a note of your dose, and bring any questions to your next check-in. Small, steady habits beat big bursts of effort every time.
