The 5 Health Checks Every Woman Should Consider Before 40

Proactive health isn't about worrying earlier — it's about understanding your body sooner.

Many health conditions that affect women develop gradually. Hormonal changes, nutrient deficiencies, reproductive health conditions and metabolic issues can all begin long before noticeable symptoms appear.

Proactive health checks can help provide a clearer picture of your baseline health, identify potential concerns earlier and guide lifestyle or medical decisions that support long-term wellbeing.

Below are five areas clinicians often recommend understanding before the age of 40.

1. A Well Woman Ultrasound

A pelvic ultrasound scan allows clinicians to assess the uterus, ovaries and surrounding pelvic structures.

This type of scan can help identify common conditions such as:

  • uterine fibroids
  • ovarian cysts
  • endometrial thickening
  • structural changes in the uterus or ovaries

These conditions are extremely common. For example:

  • Around 2 in 3 women develop fibroids during their lifetime
  • Polycystic Ovary Syndrome (PCOS) affects approximately 1 in 10 women

Many of these conditions cause few symptoms initially but may affect menstrual cycles, fertility or pelvic health over time.

A Well Woman ultrasound can provide reassurance or help guide further care if any changes are identified.

2. Hormone and Reproductive Health Testing

Hormones influence far more than reproductive health. They affect:

  • menstrual cycles
  • mood and energy
  • metabolism
  • fertility
  • skin and hair health

Hormone testing may provide valuable insight for women experiencing:

  • irregular cycles
  • fatigue
  • mood changes
  • fertility concerns

Understanding hormone patterns early can help guide lifestyle changes, medical treatment or fertility planning.

3. Iron, Vitamin D and Nutrient Levels

Nutrient deficiencies are extremely common, particularly among women.

Low iron levels can contribute to fatigue, headaches and reduced concentration. Vitamin D deficiency is also widespread in the UK due to limited sunlight exposure.

Research from Public Health England suggests that around 1 in 5 adults may have low vitamin D levels during winter months.

Blood testing can help identify deficiencies and guide targeted nutritional support rather than relying on guesswork.

4. Thyroid Function

The thyroid gland regulates metabolism, energy levels and hormonal balance.

Thyroid disorders are significantly more common in women than men, particularly during reproductive years and around pregnancy.

Symptoms of thyroid imbalance may include:

  • fatigue
  • weight changes
  • hair thinning
  • menstrual changes
  • anxiety or mood changes

Blood testing can assess thyroid hormones and help identify both underactive and overactive thyroid conditions.

5. Metabolic and Cardiovascular Health

Heart disease remains one of the leading causes of death among women globally.

Understanding metabolic markers earlier in life can help support long-term health.

Testing may include markers such as:

  • cholesterol
  • blood glucose
  • inflammation markers
  • liver function

These markers provide insight into cardiovascular and metabolic health, helping guide preventative lifestyle changes when needed.

Why Preventative Health Matters

Preventative healthcare is not about assuming something is wrong.

Instead, it provides an opportunity to:

  • understand your baseline health
  • identify potential imbalances early
  • make informed lifestyle decisions
  • monitor changes over time

Many health conditions are easier to manage when identified early, particularly those affecting reproductive health, metabolic balance and hormonal function.
