Constipation after a GLP-1 dose increase is worth noting, especially if it is a clear change from your usual bowel pattern. Gastrointestinal side effects can be more likely after treatment starts or after a recent increase, but the timing does not prove that the medicine is the only cause. The most helpful record is one that shows what changed, when it changed, and how it is affecting you.
Write down the date your prescribed regimen changed, then record your usual bowel pattern before that point as briefly as you can. Afterward, note the date and time of each bowel movement, whether it was harder than normal to pass, and whether you felt that you had fully emptied your bowels. A short daily note is enough; you do not need to make a detailed food diary unless your clinician has asked for one.
Add symptoms that may change the clinical picture: bloating, cramps, nausea, vomiting, or stomach pain. Also note whether constipation is affecting sleep, work, eating, drinking, or your ability to take other medicines as prescribed. This gives your prescriber a clearer picture than the number of days alone.
At a review, lead with the timeline: "My regimen changed on this date. My usual pattern was this. Since then I have had these symptoms and this impact." Ask your prescriber or pharmacist what is appropriate for your medicine and medical history. Do not use a symptom log to decide whether to change, delay, or restart injections yourself.
Contact your prescriber when constipation is persistent, troublesome, or accompanied by other symptoms that concern you. Seek urgent medical help for severe or rapidly worsening symptoms, especially severe persistent stomach pain or vomiting.
