Record patterns before they fade.

What a useful symptom note contains

Symptoms can be difficult to describe after they have passed. A short, consistent record can make a later conversation more specific. Record the symptom in your own words, then add:

• The date and approximate time it began.
• How severe it felt and whether it improved or worsened.
• How long it lasted and whether it returned.
• Whether it affected eating, drinking, sleep, work or normal activity.
• Medication timing and any recent prescribed dose change.
• What you did and whether that appeared to help.

Do not wait to complete a perfect entry before seeking help. The record is secondary to your safety.

Common does not always mean harmless

The MHRA identifies nausea, vomiting and diarrhoea among the common gastrointestinal effects reported with GLP-1 medicines. Many episodes are mild to moderate or short-lived, but repeated vomiting or diarrhoea can cause severe dehydration.

A clinician can consider the pattern alongside the exact medicine, dose, other medicines and your health history. An app or general article cannot make that assessment.

Warning signs that need prompt action

Seek urgent medical attention for severe, persistent abdominal pain that may radiate to the back, particularly with nausea or vomiting. The MHRA warns that this can be a sign of acute pancreatitis.

Prompt help is also important for an inability to keep fluids down, signs of severe dehydration, a serious allergic reaction, sudden or rapidly worsening vision changes, collapse, confusion or any symptom that feels severe or alarming. This list is not exhaustive. Follow the medicine leaflet and local emergency advice.

Prepare three questions for your clinician

Before a routine appointment, review your notes and select the patterns that matter most. You might ask whether a symptom is expected for your medicine, what changes should trigger earlier contact, and which instructions apply if symptoms interfere with eating, drinking or taking other medicines.

Do not change medication dose or timing in response to a pattern unless your prescriber or the medicine’s official instructions tell you to do so.
