Do you often feel excessively tired and blame it on poor sleep, stress, or a busy schedule? Sometimes, the reason can be low iron levels. Almost half of Indians are iron deficient, and many don’t even realize it. Iron deficiency can start quietly, with signs that are easy to overlook, but your body may be giving you clues long before the problem becomes serious.
From constant fatigue and pale skin to unusual cravings and increased hair fall, these signs should not be ignored. In this article, we’ll look at the common signs of iron deficiency, what can cause it, how it is diagnosed and treated, and how your diet can help improve iron levels.
Why Your Body Needs Iron
Before getting into the signs of iron deficiency, let’s understand why iron is so important in the first place. Iron is needed to make hemoglobin, a protein in your blood that carries oxygen throughout your body. When your iron levels drop, your body may not be able to deliver enough oxygen to your tissues. To cope with this, your body starts adjusting, and that’s when some of the early symptoms of iron deficiency can begin to appear.
Signs of Low Iron Levels
Fatigue
One of the first and most common signs of iron deficiency is fatigue. But this is more than just feeling a little tired after a busy day. The tiredness may not improve even after getting enough rest. You might feel exhausted doing simple activities, such as walking or climbing stairs, and may even feel short of breath.
This can happen because your muscles and tissues aren’t getting enough oxygen to work properly. Since fatigue is so common, many people don’t take it seriously, considering it a normal part of everyday life.
Paleness
Another sign to look out for is skin that is more pale than usual. One simple way to check is by gently pulling down your lower eyelid. If the inside looks significantly paler or less red than usual, it could be a sign of low hemoglobin levels.
Hemoglobin gives your blood its red color, so when its levels fall, that natural redness can become less visible.
Pica
Here’s a sign of iron deficiency that may seem strange: craving and chewing things that aren’t actually food. This might include ice, raw rice, or even chalk. This behavior is known as pica and is strongly associated with iron deficiency.
It is also fairly common during pregnancy. The exact reason for it isn’t fully understood, but it may be related to changes in brain chemistry that occur when iron levels are low.
Brittle Nails and Hair Fall
As iron deficiency continues, you may start noticing changes in areas that grow quickly, such as your nails and hair. Your nails can become thin and brittle, and in some cases, they may curve inward and develop a spoon-like shape.
This may happen because iron is involved in proper protein formation, which is important for maintaining healthy nails.
Your hair can be affected too. Iron helps keep hair in its growth phase, so when iron levels are low, more hair can shift into the shedding phase. As a result, people with iron deficiency may notice more hair fall than usual.
Changes Around Your Mouth
Another subtle sign that is often unnoticed is changes around the mouth. You may notice small cracks at the corners of your mouth, or your tongue may feel unusually smooth or have a slight burning sensation.
These areas are constantly replacing old cells with new ones, and when iron levels are low, the body may have more difficulty in keeping up with this process.
Frequent Infections
Another sign that can easily be overlooked is getting infections more often than usual. Iron also plays an important role in supporting the immune system. When your iron levels are low, your body may not be as effective at fighting off infections, which can make you more prone to getting sick.
Causes of Iron Deficiency
Iron deficiency isn’t just about recognizing the symptoms. It’s also important to understand what is causing it in the first place. There are three common reasons why your iron levels may become low.
Not Getting Enough Iron in Your Diet
The first reason is not getting enough iron through your diet. This can happen when your overall diet is lacking in iron-rich foods. It can also happen with a vegetarian diet if it isn’t planned well, since the type of iron found in plant foods is not absorbed by the body as efficiently.
Poor Absorption
Even if you’re getting enough iron from your diet, your body may not absorb it properly. This can happen with certain gut conditions, such as celiac disease and Crohn’s disease, or even after some types of surgery.
Blood Loss
The third reason is blood loss, and this is an important one to pay attention to. It can happen because of heavy menstrual periods or slow, internal bleeding in the gastrointestinal tract.
In some adults, iron deficiency may even be the first sign of bleeding somewhere in the intestine, so the underlying cause must not be ignored.
How Iron Deficiency Is Diagnosed and Treated
Iron deficiency must be taken seriously. However, the good news is that it can usually be checked with a simple blood test. One of the tests doctors may use is ferritin, which gives an idea of how much iron your body has stored. Treatment is generally not complicated. Many people see improvements with iron supplements, while some may need IV iron, especially if they cannot tolerate oral iron tablets or experience side effects such as constipation.
The right iron deficiency treatment depends on the underlying cause and your individual iron levels, so it is important to speak with a healthcare professional rather than starting high-dose supplements on your own. If you need help understanding your nutritional needs, an online dietitian consultation can help you get professional guidance based on your individual requirements.
Getting More Iron from Your Diet
Along with treatment, your diet can also play an important role in improving your iron intake. If you eat non-vegetarian foods, sources like mutton, chicken, fish, eggs, and shellfish provide iron that is generally well absorbed by the body. If you follow a vegetarian diet, include foods such as spinach, lentils, beans, and tofu.
As mentioned earlier, the iron found in plant foods is absorbed less efficiently than the iron found in animal foods. Pairing plant-based iron sources with vitamin C can help improve absorption. You can do this by adding vitamin C-rich foods to your meals like lemon, tomatoes, and citrus fruits.
It’s also a good idea to avoid tea or coffee immediately after meals, as they can reduce iron absorption. Similarly, taking calcium at the same time as iron may interfere with absorption. Even small habits, such as cooking in an iron pan, may contribute to your iron intake over time.
A personalized diet plan can make it easier to include the right combination of iron-rich foods and other essential nutrients according to your dietary preferences and nutritional needs. If you are also working toward healthy weight management, a balanced diet plan for weight management can help you maintain better overall nutrition without unnecessarily restricting important nutrients.
Could Low Iron Be a Sign of Something More?
There’s another important point to keep in mind. If you’ve been taking iron supplements for 2–3 months and your iron levels are still not improving, don’t keep increasing the dose on your own. It’s important to find out why your iron levels are remaining low.
In some cases, iron deficiency can be linked to bleeding in the digestive tract, which may sometimes be caused by conditions such as colon cancer. If your iron deficiency is unexplained or isn’t improving with treatment, speak with your doctor, who may refer you to a gastroenterologist for further evaluation.
For ongoing nutrition-related concerns, a nutritionist consultation can also help you understand your dietary intake and identify practical ways to improve your overall nutrition alongside appropriate medical care.
Listen to Your Body
If you’ve been feeling unusually tired, noticing more hair fall, or experiencing any of the other signs mentioned above, don’t ignore them. Your body may be trying to tell you that something is wrong.
Iron deficiency can have several causes, so it’s important to find out why your iron levels are low. With the right treatment, a balanced diet, and early attention to the warning signs, you can improve your iron levels and support your overall health.
Following a healthy diet plan that includes a variety of nutrient-rich foods can support your overall nutritional needs. However, persistent symptoms or suspected iron deficiency should always be discussed with a qualified healthcare professional.
