A symptom diary is a log of symptoms a person experiences. Keeping a record of symptoms can help a person gain a better understanding of them and may help with a diagnosis if a person needs to see a doctor.

A person can use a symptom diary to record symptoms of an existing health condition or to monitor their general health and log symptoms, such as headaches, menstrual cycle concerns, and gastrointestinal issues.

People may also find it useful to note if symptoms typically occur during a particular activity or at a certain time of the day. They may record anything that typically relieves their symptoms, any medication they take, food and drinks they consume, and anything that typically makes the symptoms worse.

Keeping a symptom diary may help a person better understand what is happening in their body. A person may already have a diagnosis of an existing health condition, or they may experience symptoms with a yet unknown cause.

For people with a diagnosed condition

If a person already has a diagnosis of a health condition, keeping a symptom diary can help them understand what may trigger or aggravate certain symptoms.

Recording each occurrence of a symptom allows them to look back over the diary and start to notice any consistencies. Therefore, they may be able to avoid anything that appears to trigger symptoms.

Keeping a symptom diary can also help a person with a health condition work out if there appears to be anything that helps to relieve symptoms. This can help a person manage their condition and may help them feel more in control of their health.

A symptom diary can help a person with a health condition to track if any new symptoms arise or if current symptoms appear to be getting worse. This may be useful when a person is discussing their condition with a doctor.

A 2017 study found there was an association between keeping a symptom diary and longer life spans in people with heart failure.

For people who have not received a diagnosis

A person may be experiencing symptoms but not yet have a diagnosis.

Keeping a symptom diary can help a person monitor their general health and keep a detailed record of any symptoms. This may help a doctor later when making a diagnosis.

A 2021 study of people with multiple sclerosis (MS) suggests that keeping a symptom diary can help to identify distinct, individual symptoms that can be easy to overlook due to their similarities, such as depression and anxiety.

To start a symptom diary, a person simply needs something to record the information. A person may wish to record their symptoms on paper, such as in a notebook or on a calendar.

However, a person may prefer to use technology such as a symptom-tracking app, the notes section on a smartphone or tablet, or a spreadsheet on a computer.

Once a person decides how they want to record the information, they may want to keep a watch or clock nearby to record the time at which symptoms occur.

According to Multiple Sclerosis – UK, some of the information a person may wish to record in a symptom diary can include:

  • location of the symptom
  • time the symptom occurs
  • how long the symptom lasts
  • time of the day the symptom is at its worst
  • if the symptom is constant or fluctuates
  • whether other factors, such as exercise, medications, or stress, appear to affect the symptom
  • any food or drink a person consumes
  • any alcohol or cigarettes a person uses
  • details about the symptom, such as describing it and how it makes a person feel
  • Iif anything helps to improve the symptom

When using a symptom diary to monitor general health, a person may notice new, frequent symptoms, or concerning symptoms. If a person notices anything they feel unsure about, they should speak with a doctor who can work out the underlying cause.

When keeping a symptom diary to monitor an existing health condition, a person may notice that symptoms appear to be getting worse or that new symptoms are developing.
