How to diagnose iron deficiency?

First, we need to know the symptoms of iron deficiency. A person with low iron levels may have weakness, headaches, dizziness, difficulty in concentrating and few physical signs like hair loss, pale skin, brittle nails etc. Symptoms of iron deficiency should immediately consult a doctor. A person should not take iron supplements if not prescribed by a doctor. The doctor might advise required tests to the person to confirm whether to conclude iron deficiency. The most common test of diagnosing iron deficiency is a ferritin test. Ferritin is largely a protein in our body which stores the iron and releases it when our body needs it. A ferritin test can indicate to the doctor about the iron levels of our body. A low level of ferritin shows an iron deficiency within the body.

Do iron supplements have any side effects on our bodies?

Everything has its pros and cons. Any medication that is taken without the consultation of a doctor can have few side effects on our bodies. We are not professionals, so we do not know which supplement is right for us and what should be the right dosage of the supplement. This is the reason it is always advised to consult a doctor before taking any medication. Iron supplements can have the side effects like upset stomach, constipation, nausea if not taken properly. As it is said that excess of everything is bad, just like that having excess iron in our body can cause many problems. Taking the prescribed dosage of these supplements is not likely to cause any side effects.


Iron is very essential for our body. It can be derived from diet and supplements. Earlier people used to rely only on the diet for all the vitamins and minerals.

People have the misconception that supplements are not good for our body. But over the years, the thinking of people has changed. They have started realizing that all the needs of the body cannot be fulfilled by diet alone. Iron supplements work faster than iron-rich foods and are more convenient to take.

The only thing to keep in mind is the appropriate dosage which is to be taken as every age group and gender needs different quantities of iron supplements for example women require more dosage of iron supplements as compared to men. A person should not take iron supplements just because they think they have an iron deficiency.

If they think that they might have an iron deficiency, they should get themselves examined properly so that the doctor can decide the best possible treatment for them. Taking these supplements without any reason can also be harmful for the body. If we take the supplements prescribed by the doctor, our body might take a day or two to get used to them, but they are completely safe to consume.

Most of the doctors today have started suggesting these supplements. There are many iron supplements available in the market as a lot of brands are coming up with such supplements. In the near future, the demand for these supplements will increase even more than people will become more aware of  their benefits.
