If you’ve been feeling tired all the time, dragging yourself through the day, and struggling to do even simple tasks, it might be more than merely a lack of sleep or stress. One reason that many people overlook is low iron levels. Iron is super important for keeping your body full of energy, and when you don’t have enough, your energy can drop fast. Read on to learn why iron is so important and how low iron could make you feel so worn out.

Iron Helps Keep You Energized

Iron is a really important mineral that your body needs. It helps make hemoglobin, a protein in your red blood cells that delivers oxygen throughout your body. Your cells need oxygen to make energy, which keeps you active and feeling good. When your body doesn’t have enough iron, it can’t make enough hemoglobin. This means less oxygen goes to your muscles and tissues, which makes you feel tired even if you get plenty of sleep.

Why Do Some People Have Low Iron Levels?

There are a few reasons why you might have low iron. Here are some of the most common causes:

Not Enough Iron in Your Diet: If you’re not eating enough iron-rich foods like red meat, leafy green veggies, or beans, you could become low on iron. The type of iron also matters. Heme iron, which is found in animal products, is easier for your body to absorb than non-heme iron from plants.
Blood Loss: Women are more likely to have low iron because of heavy periods. Blood loss from surgeries or accidents can also lower the amount of iron in your body.
More Iron Needed: There are times when your body needs more iron, like during pregnancy or when you’re growing quickly during your teenage years. When your body needs more oxygen, it also needs more iron.
Trouble Absorbing Iron: Some health problems, like Celiac disease or Crohn’s disease, or even some medications can make it harder for your body to absorb iron, even if you’re eating enough of it.

Signs That You Might Have Low Iron Levels

Low iron can cause different symptoms, not just feeling tired. Here are some signs to look out for:

1. Always Feeling Tired or Weak

Fatigue is the most common symptom of low iron. It’s not just feeling a little tired—it’s the kind of tiredness that makes it hard to get out of bed or do your normal activities. This kind of tiredness doesn’t usually go away, even with rest.

2. Shortness of Breath

If you find yourself getting out of breath after doing small things—like climbing a few stairs or walking a short distance—your body might not be getting enough oxygen. Shortness of breath can be a sign that you need more iron.

3. Pale Skin

Without enough iron, less oxygen-rich blood gets to your skin, which can make your skin look pale. You might notice this especially on your face, inside your lower eyelids, or on your nails.

4. Strange Cravings

Sometimes, people with low iron have cravings for things that aren’t food, like ice, dirt, or chalk. This is called pica and can be a sign of iron deficiency.

5. Headaches and Dizziness

When your brain isn’t getting enough oxygen, it can cause headaches or make you feel dizzy. If you’re feeling lightheaded more often than usual, it could be because of low iron.

How to Increase Your Iron Levels

If you think low iron might be why you’re so tired, there are some things you can do to help:

Eat More Foods That Have Iron

Adding iron-rich foods to your diet is the best way to boost your iron levels. Foods like red meat, chicken, and fish are high in heme iron, which your body absorbs easily. If you’re vegetarian or vegan, you can eat beans, lentils, tofu, nuts, and leafy green vegetables. Eating these with foods high in vitamin C, like oranges or bell peppers, can help your body absorb iron better.

Take Iron Supplements

Sometimes, changing your diet isn’t enough, especially if your iron levels are very low. Iron supplements can help, but you should only take them if your doctor tells you to because too much iron can be harmful. Your doctor can suggest a supplement that’s safe and works well for you.

Treat Any Health Problems

If low iron is caused by a medical condition like Celiac or Crohn’s disease, treating that condition can help your body absorb more iron. If heavy periods are the problem, your doctor can also help you find ways to manage it.

When Should You See a Doctor?

If you’re always feeling tired and think it might be because of low iron, see your doctor. A simple blood test can tell if your iron levels are low, and your doctor can help you make a plan to feel better. Don’t start taking iron supplements on your own—it’s important to get your doctor’s advice since too much iron can also cause problems.

The Bottom Line

Feeling tired all the time can be frustrating, specifically if you’re not sure why. Low iron is a common reason, and it can make you feel drained and incapable of enjoying life. The better news is that with some changes to your diet and the right care from your doctor, you can raise your iron levels and start feeling like yourself again.

Therefore, if you’re feeling low on energy and can’t keep up with your usual activities, consider that low iron might be the reason. And keep in mind that a visit to your doctor can help you find out what’s going on and get you back to feeling better.
