Iron, bone and heart across the decades

Much of what circulates as general health advice was validated on study populations that were predominantly male, and a good deal of it translates fine. In several specific areas it does not, and those areas deserve explicit attention.

Iron

Iron deficiency is common in menstruating women and can produce fatigue, reduced exercise capacity, poor concentration and hair changes well before anaemia appears on a standard blood count. Ferritin — which reflects iron stores — is not always included in routine panels, so it may be worth asking about specifically when fatigue is the presenting concern. Supplementation should follow testing rather than precede it; excess iron carries its own risks, and self-treating can mask a cause worth identifying.

Bone

Bone density peaks in early adulthood and declines afterwards, with an accelerated period around the menopausal transition. Two things follow. First, the resistance training and adequate protein, calcium and vitamin D that build peak bone mass matter most in the decades when nobody is thinking about fractures. Second, weight-bearing and resistance exercise remain valuable later, alongside attention to fall risk — balance and leg strength do as much practical good as anything else on the list.

Heart

Cardiovascular disease is the leading cause of death in women, which remains widely underappreciated. Two points are worth knowing:

• Symptoms can present differently. Alongside chest pain, women more frequently report shortness of breath, nausea, jaw or back pain, or unusual fatigue. Any of these, particularly if new and unexplained, warrants urgent assessment.
• Some risk factors are sex-specific. A history of pre-eclampsia, gestational diabetes, or pre-term delivery is associated with elevated later cardiovascular risk. This history is worth raising explicitly — it is not always asked about.

Pregnancy history is cardiovascular history. Bring it to the appointment even if the pregnancy was decades ago.

The practical version

Know your blood pressure, lipids and glucose. Include resistance training. Ask about ferritin if fatigue is persistent. Raise pregnancy complications, cycle changes and menopausal symptoms directly rather than waiting to be asked. And treat new, unexplained cardiac-type symptoms as urgent rather than as something to monitor.
