Low iron from heavy periods? It is more common than you might think and it is often overlooked.
For many women, a heavy period is something they have learned to manage quietly. Planning outfits around it. Doubling up on products. Pushing through the fatigue. But when bleeding is consistently heavy or prolonged, it can start to impact more than just your monthly routine. It can affect your iron levels and, over time, your overall wellbeing.
Here is what is actually happening in your body.
Each month, your body loses blood during your period. When that bleeding is heavier than usual, you are also losing more iron. Iron is a key mineral that helps your red blood cells carry oxygen around your body. When your iron stores drop, your body has to work harder to do the same job. That is when symptoms start to show up.
You might notice you are feeling constantly tired, even after a full night’s sleep. You could feel lightheaded when you stand up, short of breath when walking upstairs, or just generally run down. Some people also experience headaches, brain fog, or a drop in their usual energy and motivation. These can all be signs of low iron or iron deficiency anaemia.
The tricky part is that many people normalise these symptoms. Busy lifestyle, stress, poor sleep. It is easy to explain them away. But if you are also dealing with heavy periods, it is worth connecting the dots.
So what actually counts as a heavy period?
It can look different for everyone, but common signs include bleeding that lasts longer than seven days, needing to change your pad or tampon every one to two hours, passing large clots, or bleeding that interferes with your daily life. If you are planning your day around your period, that is a signal your body might need some support.
Food can absolutely help support your iron levels. Think iron rich options like red meat, lentils, beans, tofu, and leafy greens. Pairing these with vitamin C rich foods can help your body absorb iron more effectively. But for some people, especially when iron levels are already low, diet alone is not always enough.
Oral iron supplements are often the first step, but they do not suit everyone. They can take time to work and sometimes cause side effects like nausea or constipation. This is where iron infusions can come in.
Iron infusions are a way of delivering iron directly into your bloodstream. They can help restore iron levels more quickly and are often considered when levels are significantly low or when tablets have not been effective.
Most importantly, heavy periods and ongoing fatigue are not something you have to just put up with. Your body is giving you information. Listening to it and getting the right support can make a real difference to how you feel day to day.
If any of this sounds familiar, it is worth having a conversation with your GP. A simple blood test can check your iron levels and help guide the next steps.
Because feeling exhausted all the time should not be your normal.
