If you are struggling with persistent fatigue, breathlessness, or brain fog caused by iron deficiency, a private GP for iron infusion Palmers Green can help you feel better quickly. I am Dr Mitesh Parmar MBBS MRCGP, Principal GP and Clinical Director at Clinique Alpa in Palmers Green, North London. I offer private intravenous iron infusions for patients who have not responded to iron tablets or who need their iron levels restored rapidly. In this post, I will explain how iron deficiency affects your body, why oral iron supplements do not work for everyone, and what to expect from an iron infusion at my clinic.
Understanding Iron Deficiency: More Common Than You Think
Iron deficiency is the most common nutritional deficiency worldwide, affecting an estimated 1 in 3 people globally according to the World Health Organisation. In the UK, iron deficiency anaemia affects approximately 3% of men and 8% of women, but iron deficiency without anaemia (sometimes called latent or subclinical iron deficiency) is far more prevalent and frequently missed.
Your body needs iron to produce haemoglobin, the protein in red blood cells that carries oxygen from your lungs to every tissue and organ. Iron is also essential for producing myoglobin (which supplies oxygen to your muscles), for energy metabolism, and for normal cognitive function. When your iron stores become depleted, your body cannot produce enough healthy red blood cells, and every system begins to feel the impact.
The symptoms of iron deficiency can be debilitating. Fatigue that does not improve with rest is the hallmark symptom. Other common symptoms include breathlessness on exertion, dizziness, headaches, difficulty concentrating, poor memory, restless legs, hair loss, brittle nails, pale skin, mouth ulcers, and increased susceptibility to infections. Many patients I see have been living with these symptoms for months or years, often attributing them to stress, poor sleep, or simply getting older.
Why Iron Tablets Do Not Work for Everyone
The standard NHS approach to iron deficiency is to prescribe oral iron supplements. These are inexpensive and effective for many patients, but they have significant limitations.
Oral iron is poorly absorbed by the body. Only about 10% to 15% of the iron in a tablet is actually absorbed into your bloodstream, and this figure drops further if you take the tablet with food, tea, coffee, or certain medications. The unabsorbed iron sits in your gut and causes side effects: nausea, stomach cramps, constipation, diarrhoea, and dark stools. These side effects lead many patients to stop taking their iron tablets before their stores are replenished.
Even with perfect adherence, oral iron takes 3 to 6 months to restore iron stores fully. For patients with ongoing blood loss (such as heavy periods), malabsorption conditions (such as coeliac disease or inflammatory bowel disease), or very low ferritin levels, oral iron may never be able to keep up with the rate of loss. NICE Clinical Knowledge Summaries recommend considering intravenous iron when oral iron is not tolerated, is ineffective, or when rapid correction of iron deficiency is clinically needed.
From Our Practice: When Fatigue Has an Underlying Cause
These 2 recent cases from my clinic illustrate patterns I see frequently.
A young woman contacted me regarding ongoing painful, heavy periods that had been worsening over the past few years. The pain during episodes was so severe that she was unable to function while waiting for pain relief to take effect. She also experienced cramps between periods. Previous investigations including a pelvic ultrasound had been normal. Her blood tests showed normal ferritin and full blood count results at that point. I arranged hormonal profile bloods and discussed the Mirena coil as a potential treatment option for managing her heavy menstrual bleeding.
Another patient, a teenage girl attending for an ADHD shared care assessment, had a history of previous iron deficiency anaemia that had been treated with iron tablets. She reported constant tiredness and lethargy lasting approximately 18 months. Her recent blood tests at her NHS GP had been reported as normal.
These cases illustrate a common pattern I see in my clinic: patients with fatigue and heavy periods where iron deficiency may be an underlying factor, even when initial blood results appear within normal range. The challenge is that “normal” ferritin ranges on laboratory reports can be misleading. Most UK laboratories report ferritin as normal if it falls above 10 to 15 micrograms per litre. However, many patients experience symptoms of iron deficiency at ferritin levels below 30, and some guidelines, including those from the British Society for Haematology, suggest that optimal ferritin for symptom resolution is above 50 micrograms per litre.
This is why I take a thorough approach to investigating fatigue. A single “normal” blood test result does not always tell the full story. I look at ferritin, serum iron, transferrin saturation, total iron binding capacity, full blood count indices including mean cell volume and mean cell haemoglobin, and inflammatory markers (as ferritin can be falsely elevated by infection or inflammation). This comprehensive blood panel through our test services gives a much clearer picture of your iron status.
What Is an Iron Infusion and How Does It Work?
An iron infusion delivers iron directly into your bloodstream through an intravenous drip. This bypasses the gut entirely, so there are no gastrointestinal side effects and absorption is close to 100%. A single infusion can deliver 1,000mg of iron, equivalent to approximately 3 months of oral iron supplementation.
The infusion takes approximately 30 to 60 minutes, depending on the preparation used and the dose required. You sit comfortably in a treatment chair while the iron solution is administered through a small cannula in your hand or arm. I monitor you throughout the infusion and for 30 minutes afterwards, as recommended by the product safety guidelines.
Most patients notice an improvement in their energy levels within 1 to 2 weeks of the infusion, as their body uses the iron to produce new red blood cells. Full blood count and ferritin levels typically normalise within 4 to 6 weeks. I arrange follow up blood tests at 6 to 8 weeks to confirm that your iron stores have been adequately replenished.
Who Is Suitable for a Private Iron Infusion?
I recommend intravenous iron for patients who meet 1 or more of the following criteria.
Patients who have tried oral iron supplements and experienced intolerable side effects such as nausea, constipation, or stomach pain. Patients who have taken oral iron for 3 months or more without adequate improvement in their ferritin levels. Patients with malabsorption conditions including coeliac disease, Crohn’s disease, ulcerative colitis, or previous gastric surgery. Patients with ongoing blood loss from heavy menstrual periods, gastrointestinal bleeding, or frequent blood donation. Patients who need rapid correction of iron deficiency before planned surgery. Patients with chronic kidney disease or heart failure where iron deficiency contributes to symptoms.
Before prescribing an iron infusion, I always conduct a thorough clinical assessment and blood tests to confirm iron deficiency and exclude other causes of your symptoms. Iron infusions are not appropriate for patients whose anaemia is caused by factors other than iron deficiency, such as vitamin B12 deficiency, folate deficiency, or chronic disease.
What to Expect From Your Iron Infusion Appointment
Before the Infusion
You will have an initial consultation and blood tests to confirm iron deficiency and assess your suitability for intravenous iron. I review your medical history, current medications, and any allergies. If you have had a previous allergic reaction to intravenous iron, this must be discussed before proceeding. There is no need to fast before the infusion. You can eat and drink normally on the day.
During the Infusion
The infusion is administered in our treatment room at Clinique Alpa. A small cannula is inserted into a vein in your hand or arm, and the iron solution is diluted in saline and infused over 30 to 60 minutes. You may feel a mild sensation of warmth or a metallic taste during the infusion; this is normal and temporary. I remain available throughout the infusion to monitor you and address any concerns.
After the Infusion
You are observed for 30 minutes after the infusion is complete. Most patients feel well enough to drive home and return to normal activities the same day. Some patients experience mild side effects in the 1 to 2 days following the infusion, including headache, mild muscle or joint aches, or temporary skin staining at the infusion site. Serious allergic reactions are rare, occurring in fewer than 1 in 1,000 infusions, and I have resuscitation equipment and trained staff available at all times.
Iron Infusions and Heavy Periods: A Common Connection
Heavy menstrual bleeding (menorrhagia) is one of the most common causes of iron deficiency in women of reproductive age. NICE defines heavy menstrual bleeding as excessive blood loss that interferes with a woman’s physical, social, emotional, or material quality of life. Approximately 1 in 4 women in the UK experience heavy periods at some point.
The challenge is that many women accept heavy periods as normal, particularly if they have always had them. They may not realise that their fatigue, breathlessness, and poor concentration are caused by iron deficiency resulting from monthly blood loss. If you are experiencing heavy periods alongside fatigue, I strongly recommend blood tests to check your iron status, even if previous tests have been reported as normal.
For patients whose iron deficiency is driven by heavy periods, an iron infusion can restore iron levels quickly, but it is equally important to address the underlying cause of the blood loss. I discuss treatment options including hormonal management and referral to gynaecology where appropriate. This dual approach, treating the deficiency and addressing its cause, provides lasting benefit rather than a temporary fix.
Traffic Light Guide: When to Seek Help for Fatigue and Iron Deficiency
🟢 GREEN (Self Care): Mild fatigue that improves with better sleep, regular exercise, and a balanced diet rich in iron containing foods (red meat, dark leafy greens, lentils, fortified cereals). You can take an over the counter iron supplement if your diet is low in iron, but see your GP if fatigue persists beyond 4 weeks.
🟠 AMBER (See Your GP): Persistent fatigue lasting more than 4 weeks that does not improve with lifestyle changes. Heavy periods with fatigue, breathlessness, or dizziness. Hair loss, brittle nails, restless legs, or mouth ulcers alongside tiredness. Previous iron deficiency that may have recurred. Iron tablets causing side effects that make you want to stop taking them.
🔴 RED (Seek Urgent Care): Severe breathlessness at rest or with minimal exertion. Chest pain or palpitations. Fainting or near fainting episodes. Very heavy menstrual bleeding with flooding or clots larger than a 50p coin, especially if you feel faint or dizzy. Blood in your stools or very dark, tarry stools. These symptoms require same day medical assessment.

Frequently Asked Questions About Iron Infusions
How Quickly Will I Feel Better After an Iron Infusion?
Most patients begin to notice an improvement in energy levels within 1 to 2 weeks of their infusion. Full blood count and ferritin levels typically normalise within 4 to 6 weeks. The speed of improvement depends on the severity of your deficiency and whether the underlying cause of iron loss has been addressed.
Are Iron Infusions Safe?
Iron infusions are generally very safe. Mild side effects such as headache, temporary muscle aches, and skin staining at the infusion site occur in a small number of patients. Serious allergic reactions are rare, occurring in fewer than 1 in 1,000 infusions. I monitor you throughout the infusion and for 30 minutes afterwards, and resuscitation equipment is available at all times in accordance with national guidelines.
How Long Does an Iron Infusion Take?
The infusion itself takes approximately 30 to 60 minutes, depending on the dose. You are then observed for 30 minutes afterwards. Including preparation and observation time, you should allow approximately 90 minutes to 2 hours for the full appointment.
Will I Need More Than 1 Iron Infusion?
Many patients only need a single infusion to restore their iron stores. However, if your iron deficiency is caused by ongoing blood loss (such as heavy periods) or a malabsorption condition, you may need repeat infusions every 6 to 12 months. I arrange follow up blood tests at 6 to 8 weeks after your infusion to check your response and advise on whether further treatment is needed.
Can I Have an Iron Infusion if I Am Pregnant?
Iron infusions can be given during pregnancy, typically from the second trimester onwards, when oral iron is not tolerated or is insufficient. Iron deficiency anaemia in pregnancy is associated with increased risk of preterm delivery and low birth weight, so effective treatment is important. I assess each case individually and liaise with your obstetric team where appropriate.
