Low energy can be hard to describe because it may look like sleepiness, weakness, poor concentration, heavy limbs, or simply not being able to do your usual day. While using a GLP-1, the most useful record is a short note about timing and impact, not a guess about the cause.
Write down when the fatigue began, how long it lasted, and whether it was mild, moderate, or severe for you. Add where you were in your treatment week and whether anything recently changed, such as your prescribed dose, another medicine, illness, travel, sleep, work demands, or activity.
Food and fluid context can help. Note whether you ate and drank about as usual, less than usual, or found meals difficult because of nausea, fullness, vomiting, diarrhoea, constipation, heartburn, or taste changes. Do not use the note to set a target or force a plan; just show what happened.
If you have diabetes or take other medicines that can affect blood sugar, include that context in your review notes. Dizziness, shakiness, sweating, palpitations, headache, or unusual weakness should be discussed with your healthcare team according to the advice they have given you.
Contact your prescriber, pharmacist, or another qualified healthcare professional if fatigue is persistent, severe, worsening, comes with other symptoms, or affects driving, work, caring responsibilities, or daily function. Seek urgent help for symptoms that feel sudden, severe, or rapidly worsening.
