Understand periods in swimming

Heavy Bleeding, Dizziness & Feeling Unwell

Warning signs coaches should recognise without trying to diagnose them.

Coaches do not need to diagnose period problems, but they should know when a swimmer's symptoms need more than a quick poolside adjustment.

Heavy bleeding

Encourage a swimmer to tell a parent, carer or healthcare professional if they report patterns such as:

  • needing to change a pad or tampon every one to two hours;
  • bleeding through clothing or bedding regularly;
  • periods lasting longer than seven days;
  • needing more than one type of product because one is not enough;
  • avoiding normal activities because of bleeding;
  • feeling very tired or short of breath.

A coach does not need to decide whether the bleeding meets a medical definition. The key is to recognise that repeated disruption deserves follow-up.

Dizziness or fainting in a pool environment

Treat dizziness and faintness seriously because water adds an immediate safety risk.

If a swimmer feels faint, dizzy, confused, unusually weak or unwell:

  1. get them out of the water safely;
  2. sit or lie them somewhere safe as appropriate;
  3. follow your facility's first-aid process;
  4. contact a parent or carer where appropriate;
  5. seek urgent medical help if symptoms are severe or do not improve.

Do not assume symptoms are caused by menstruation. Dehydration, illness, low energy intake and many other issues can cause similar symptoms.

Unusual tiredness

Repeated unusual tiredness can be worth discussing, particularly when combined with heavy bleeding, shortness of breath, dizziness, repeated injury or falling performance.

Signpost rather than diagnose.

Changes in established periods

If a swimmer says established periods have become much heavier, much more painful, very irregular or have stopped for several months, encourage them to speak to a parent, carer or healthcare professional.

High training loads and low energy availability can affect menstrual health, but there are many other possible causes.

Keep the conversation private

Do not discuss heavy bleeding, missed periods or other symptoms in front of teammates.

If you need to document a welfare concern, follow club policy and share information only with people who need it.

Remember

When symptoms move beyond ordinary inconvenience and start affecting safety or daily life, the coach's role is to notice, support and signpost.

Keep in mind: Coaches, teachers and clubs support, protect privacy and signpost. They do not diagnose. Severe pain, fainting, dizziness or significant illness should follow club, school or facility first-aid procedures and be passed to a parent, carer or healthcare professional.
