Headache and dizziness are symptoms where details matter. A note that says "felt off" may be true, but it is hard to act on later. A clearer record separates what you felt, when it happened, and how much it affected your day.
For headache, record the time it began, where the pain was, how intense it felt, and whether it came with nausea, vision changes, sensitivity to light, fever, vomiting, or abdominal pain. For dizziness, write whether it felt like lightheadedness, spinning, unsteadiness, or feeling faint.
Add practical context: your GLP-1 treatment week, recent prescribed dose change, eating and drinking pattern, sleep, stress, illness, activity, alcohol, travel, and any other medicines. These details help your prescriber look for a pattern without assuming one cause.
If you use insulin, sulfonylureas, or other diabetes medicines, mention that in your notes and follow the individual plan your healthcare team has already given you. Do not drive, ride a bike, or use machinery if dizziness or vision problems make that unsafe.
Contact your prescriber, pharmacist, or another qualified healthcare professional if headaches or dizziness are persistent, severe, worsening, new for you, or affecting daily safety. Seek urgent medical help for severe or rapidly worsening symptoms, fainting, chest pain, trouble breathing, sudden vision changes, or symptoms that feel serious.
