Low Iron Symptoms in Women: A Case Study on Getting Energy Back

Some of the most tired women I meet are also some of the healthiest eaters. This client was eating one of the best diets I had seen at a first appointment, and was still running on empty. Her case shows how low iron symptoms in women slip through the net, and what it takes to put them right.

She was 47, with two children, a demanding job, and a husband who often worked away. She felt dizzy at times and reached for something sweet to keep going. She had recently given blood, and the donation centre flagged that her iron was low.

What causes iron deficiency?

Iron deficiency almost never comes out of nowhere, and finding the reason matters as much as topping the iron back up.

• Blood loss. Heavy periods are a leading cause in women, and internal bleeding or blood in the stool.

• Not enough coming in. A diet low in iron-rich foods leaves the body short of raw material.

• Poor gut absorption. Coeliac disease, Helicobacter pylori, Crohn's, ulcerative colitis, SIBO and candida disturb the gut lining. Low stomach acid, very high doses of turmeric and medications such as PPIs all lower how much iron you absorb.

• Bad timing at meals. Dairy, high-fibre foods, coffee, tea and green tea block iron uptake alongside a meal. The food is not the enemy. The timing is.

  
  

Symptoms of low iron

Red blood cells use iron to carry oxygen from your lungs to every cell. Picture iron as the delivery van and oxygen as the parcel. Too little iron means too few vans on the road, and cells left waiting on a delivery that never comes.

That is why low iron shows up as a cluster, not a single sign:

• Fatigue that adequate sleep does not relieve

• Dizziness and a sense of weakness

• Pale skin

• Bruising that comes up with the smallest knock

• Hair that starts to thin

• Brain fog, confusion and short-term memory lapses

• Aches in the joints and muscles

On its own, each sign points somewhere different. Together, they point at iron.

Normal is not the same as optimal

When your iron is checked, the result gets compared to a reference range, and if you sit inside it you are told it is fine. The bottom of the range is still the bottom though, and I often see women there, normal on paper and feeling anything but. In clinic, women tend to feel far better when their ferritin, the marker for stored iron, sits between 70 and 90 mcg/L and their serum iron between 20 and 25 umol/L, higher than the point at which a result stops being flagged. Your GP is not wrong to use the range, but it catches deficiency and rules out disease rather than finding the level at which you feel well.

What we did

Topping up iron is the easy part. Getting it to absorb, and clearing the road so the body can use it, is the real work. Over six weeks we:

• Sorted her digestion. Her motility was slow and she was not passing a good-sized stool comfortably each day. A sluggish bowel lets waste recirculate, causing brain fog and fatigue, so we raised soluble fibre.

• Rebuilt breakfast. It leaned on seeds and nuts and ran short on protein, so her blood sugar dipped and she reached for something sweet. We increased protein in all her meals and snacks and made sure they contained enough fibre and fat to balance her blood sugar and keep her energy stable throughout the day.

• Fixed the timing. We kept tea and coffee two hours clear of meals and cut right down on alcohol, which blocks iron, disturbs sleep and leaves you feeling flat the next day.

• Improved absorption. A betaine HCl supplement raised her stomach acid, and we chose iron bisglycinate, gentler than ferrous sulphate and less likely to cause constipation. A good quality menopause multinutrient supported her energy, and mindful eating helped her body produce the enzymes it needs to break down and absorb nutrients. We also paired iron-rich foods with vitamin C rich foods to increase iron absorption.

• Protected her sleep. She was often woken in the night by family, so we set a proper bedtime and worked on her sleep routine.

  
  

The results

Six weeks in, she felt a great deal less tired. She understood which foods worked for her and which worked against her, and cut her alcohol for good because the difference was too clear to ignore. Her energy came back to where it should be.

Her words

"I went to Clare after being diagnosed with low iron levels. We worked together over 6 weeks and the change has been fantastic. Clare was extremely thorough in her investigations and our weekly online chats were so helpful discussing my progress and any challenges to see what worked best for me. She was quick at responding to chat messages too. Now my energy levels are back to normal thanks to her excellent nutritional advice. I would highly recommend working with Clare."

A word of caution: never take iron blind

Please do not start an iron supplement without knowing your levels. Iron is not like vitamin C, which the body flushes out. The body stores iron, and too much is toxic. Low iron can also be a sign of something that needs a GP's attention, such as bleeding in the gut, and a supplement can paper over it. Get tested first, then a plan can be built that is safe and made for you.
