Puberty health checks: what to expect each year
Puberty health checks are a yearly well visit that covers growth, vaccines (HPV, Tdap and MenACWY), periods and mood, with eyes, teeth and skin checked alongside. The vaccines and knowing which signs deserve a doctor's visit matter most, and our puberty guide shows where this fits in the wider picture.
Most of puberty is normal change on its own schedule, so the checks at this stage are gentle ones. They give a teen practice at something she'll use for life: describing how her body feels and asking her own questions. If you're a teen reading this yourself, welcome. None of this is a test you can fail.
What do puberty health checks include?
At a typical US visit, a pediatrician or primary care provider checks height and growth, reviews vaccines, asks about periods, mood and sleep, and leaves room for her own questions. The UK has no yearly visit, so a GP or school nurse is the usual first contact. Most of it is a conversation, and the vaccines are the only part that needs a needle.
It helps to know the usual signs of puberty in girls and what a typical first period looks like, so the questions you bring are specific ones.
Not every check needs an appointment. The period diary and the strength check are ones she can run herself, at home or with a coach, and both put her in charge of her own information. Eyes and teeth have their own appointments, so they're easy to lose track of once childhood routines loosen.
For the years before this one, our childhood health checks page covers the earlier schedule. For young women who have left the teen years behind, the next stage's page on fertility by age is the place to go. The whole picture, stage by stage, sits in our guide to health checks for women.
Check, when, what to look for
| Check | When | What to look for | Guidance by country |
|---|---|---|---|
| Well visit | Yearly | One appointment that gathers growth, vaccines and any questions in the same place.A short list of questions written beforehand helps a teen speak for herself. | – |
| HPV vaccine | Age 11–12; it can start at 9. | Protection that prevents most cervical cancers.Catch-up is available up to age 26. | The UK gives 1 dose at age 12–13 (NHS). |
| Tdap and MenACWY vaccines | Age 11–12, with a MenACWY booster at 16. | MenACWY protects against meningitis, a higher risk for teens and college students.The booster comes years after the first dose, so a calendar reminder is worth setting. | UK: Td/IPV and MenACWY at 14. |
| Puberty timing | Worth a doctor's visit if there is no breast development by 13, or no period by 15. | Whether she is a late developer, as most are, or one of the few who need treatment.Asking is reassuring whichever way the answer goes. | – |
| Period diary | Ongoing, from the first cycle. | Cycle length, heaviness, pain and mood.It becomes useful evidence for a doctor appointment. | – |
| Iron (ferritin) and blood count | If periods are heavy or she's often tired. | A blood test for iron stores, run alongside a blood count.Low iron is common and treatable. | – |
| Growth and weight | At yearly well visits. | BMI percentile for age (centile in the UK), not adult BMI.Sudden changes on her growth chart are worth a conversation about health and energy. | – |
| Eyes | Every 1–2 years. | Nearsightedness, which often appears in the teens.In the UK this is called short-sightedness and the test is done by an optician. | – |
| Dentist | Every 6–12 months. | Decay, gum health and orthodontics.It's worth asking about sealants and fluoride. | – |
| Skin | As needed. | Acne that scars or affects confidence.A pediatrician, GP or dermatologist is a good first conversation, and there's no need to wait it out. | – |
| Mental health | Ongoing. | Low mood, anxiety, self-criticism about food or body, or withdrawal.A few mood questions are a routine part of the well visit, and raising a worry early gives her more options. | – |
| Sexual health | If sexually active. | Chlamydia and gonorrhea tests.Testing is free and confidential at sexual health clinics, and home test kits are available. | – |
| Strength and fitness | Each school term. | Push-ups, plank, standing long jump and a 1 km run time.It tracks progress in strength and stamina from one term to the next. | – |
Which signs are worth a doctor's visit between yearly checks?
Between yearly checks, a short appointment is worth booking for lasting tiredness, periods that are very heavy or painful, puberty that seems to be running late, acne with excess hair growth, or changes in mood or eating. A visit is how a family finds out what is behind any of these, and the answer is often a reassuring one.
Tiredness and heavy bleeding often show up together, and a blood test is the usual step when they do. Our page on iron deficiency anemia treatment (spelled anaemia in the UK) explains what helps once the result is back.
Changes that arrive unusually soon are a separate question, and we cover it on our early puberty page.
A diary turns a vague worry into something a doctor can act on, and it is especially helpful for heavy periods. Period pain that stops school or doesn't ease with painkillers deserves a visit too, even though cramps are so often described as normal.
How she talks about food, her body and herself counts just as much as any physical sign. A change there is a good reason to book sooner than the next yearly slot, and a gentle, curious question at home is often what opens the door.
Which vaccines and tests are offered in the teen years?
The teen years bring the HPV vaccine, Tdap and MenACWY, plus a small number of tests done for a reason, not by the calendar. Names and timing differ between countries. In the UK, the NHS offers a single HPV dose in school year 8 (age 12–13), and under-25s usually need just 1 dose; Td/IPV and MenACWY follow at 14.
If a dose was missed or you're unsure what she has had, our page on when to get the HPV vaccine is a good place to start. Families who have moved between countries often find it helps to bring the vaccination record to the first appointment, so nothing is doubled or skipped.
Of the tests, ferritin is the blood measure of stored iron, checked alongside a blood count when her periods or energy suggest it. Chlamydia and gonorrhea testing is for those who are sexually active, and she can ask for it at a well visit or go straight to a sexual health clinic.
Facts
Common questions
How many doses of the HPV vaccine does a teen need?
In the US it takes 2 doses, 6–12 months apart, if the first is given before the 15th birthday; starting at 15–26, or having a weakened immune system, means 3 doses (CDC). In the UK, under-25s usually need 1 dose, and catch-up runs to the 25th birthday. A pediatrician, GP or school nurse can check her record.
Is a depression screen a normal part of a teen checkup?
Yes. The USPSTF recommends screening all adolescents aged 12–18 for major depressive disorder, so a few questions about mood are routine and not a sign that anyone is worried about her in particular. Many parents find it helps to mention this beforehand, so the questions don't come as a surprise on the day.
Does a sexually active teen need testing if she feels fine?
The evidence supports it. The USPSTF recommends chlamydia and gonorrhea screening for sexually active females aged 24 and under, which makes the test a routine one for her whole age group, with no judgment attached. She can raise it at a well visit, or go straight to a sexual health clinic if she prefers privacy.
What counts as a typical cycle in a period diary?
The NHS describes a typical cycle as 21–35 days, counted from the first day of one period to the first day of the next, with bleeding that lasts 2–7 days. In the UK, periods usually start around 12 and most people have regular periods by 16–18. Cycles can wander in the first years, which is one reason a diary helps.
When should we see a GP about missed periods?
The NHS suggests seeing a GP after 3 missed periods in a row with a negative pregnancy test. US families can start with a pediatrician or ob-gyn. Bringing the diary, with start dates and any pain or mood notes, gives the appointment a head start.
What should we bring to an appointment if something seems off?
The period diary, the vaccination record and a short list of questions make a good start, so the appointment can begin with facts on the table. In the UK, a school nurse can also be a gentle first conversation if talking to a GP feels like a big step.
Next steps
A good place to start is the calendar: when the last well visit was, and whether the vaccination record has any gaps for her age and country. From there, a period diary and a strength check each school term are two small habits she can own herself. If anything on the red flag list sounds familiar, many families find that booking a visit sooner brings welcome peace of mind, and there's no need to hold it for the next yearly slot. Some teens want every detail and others want one trusted adult to ask, and she gets to decide which fits her, because this is not one size fits all.
