Women who consistently feel exhausted even after a full night's sleep are being strongly advised to speak with their GP about potential iron deficiency anaemia. This common condition, affecting billions globally, is frequently dismissed as merely the result of hectic modern lifestyles, but ignoring its warning signs can lead to significant health risks.
The Hidden Danger of Persistent Fatigue
On his popular No Appointment Necessary podcast, NHS GP and ITV regular Dr Amir Khan highlighted that it is "so common" for women at or below perimenopausal age to develop anaemia due to blood loss from menstruation. Perimenopause typically begins in a woman's 40s, with the average onset age being around 47.
Dr Khan explained: "The kind of symptoms we look out for are tiredness, [it] is the most common symptom. Women often put their tiredness down to being busy because they are busy people, managing a lot. If you are so tired that, even after sleep, you don't feel refreshed, you could well be anaemic."
Beyond Fatigue: Additional Warning Signs
Recurring infections can also serve as important warning signals, according to Dr Khan. He detailed that since the body requires iron and red blood cells to maintain a robust immune system, individuals who don't produce sufficient amounts naturally become more susceptible to these health problems.
Beyond the symptoms highlighted by Dr Khan, other frequently reported indicators of iron deficiency anaemia include:
- Persistent headaches
- Unusually pale skin
- Shortness of breath during normal activities
- Noticeable heartbeats or palpitations
The NHS website also lists restless leg syndrome as one of the rarer anaemia indicators. This condition causes a powerful compulsion to move your legs, often while resting during evening hours.
The Serious Consequences of Untreated Anaemia
Getting appropriate medical help is crucial if you suspect iron deficiency anaemia. When left untreated, this condition can increase susceptibility to illness and infection while potentially heightening the risk of developing complications affecting the heart or lungs.
For pregnant women, untreated anaemia poses greater risks of complications both before and after birth. According to NHS information, iron deficiency anaemia represents the most common form of anaemia worldwide, with heavy menstrual periods and pregnancy being among the primary causes.
Diagnosis and Treatment Pathways
To confirm a diagnosis, GPs typically carry out blood tests and may also enquire about lifestyle factors and medical history. Once the underlying cause of iron deficiency anaemia has been identified, appropriate treatment can begin.
Should tests reveal a low red blood cell count, doctors will usually prescribe iron tablets that need to be taken for approximately six months. Throughout treatment, medical professionals may order repeat blood tests every few months to monitor whether iron levels are returning to normal ranges.
The Crucial Role of Diet in Prevention
Alongside medication, diet plays a fundamental role in maintaining healthy iron levels and preventing anaemia. Iron is a vital mineral our bodies need to produce red blood cells, which transport oxygen throughout our systems. Since the human body doesn't naturally produce iron, dietary intake becomes the most effective way to ensure sufficient daily iron consumption.
According to NHS guidelines, the amount of iron required varies depending on age and gender assigned at birth:
- Men over 19 and women over 50 need 8.7mg per day
- Women aged 19-49 are advised to double that intake to 14.8mg daily, accounting for blood loss during menstrual periods
Iron-Rich Foods to Incorporate
A variety of iron-rich foods can help the body meet these daily requirements. The NHS recommends people try to eat more of the following:
- Dark-green leafy vegetables like watercress and curly kale
- Cereals and bread with extra iron (fortified varieties)
- Red meats including beef, lamb, pork, veal, mutton, venison, and goat
- Beans such as red kidney beans, edamame beans and chickpeas
- Dried fruit including apricots, prunes and raisins
- Pulses like beans, peas and lentils
People should also consider reducing consumption of tea, coffee, milk and dairy products. Foods containing high levels of phytic acid, such as wholegrain cereals, can prevent your body from properly absorbing iron from other foods and supplements.
By recognizing the warning signs, seeking timely medical advice, and maintaining appropriate dietary habits, women can effectively address iron deficiency anaemia before it leads to more serious health complications.
