What is anemia?

Anemia is a condition in which red blood cell or hemoglobin levels fall below the normal range, leaving the body unable to carry enough oxygen throughout the body. Normal hemoglobin ranges differ by sex and age.

Iron-deficiency anemia, the most common type

Among the various types of anemia, iron-deficiency anemia — where insufficient iron prevents adequate hemoglobin production — is by far the most common. A limited diet, chronic bleeding, or impaired iron absorption can be major causes.

Common symptoms

Easy fatigue and low energy, dizziness, heart palpitations, and paleness of the face or nails are classic symptoms. Shortness of breath or reduced concentration can also occur alongside these.

Why women are more vulnerable

Because women lose blood monthly through menstruation, they lose more iron than men and are known to be more vulnerable to iron-deficiency anemia. During pregnancy, iron demand rises further as it is transferred to the fetus, raising the risk of anemia.

Iron-rich foods

Red meat, liver, egg yolks, leafy greens like spinach, and legumes are known to be relatively rich sources of iron. Eating them alongside vitamin C is said to help with iron absorption.

Why identifying the underlying cause matters

For severe or unexplained anemia, other underlying conditions such as digestive tract bleeding, chronic disease, or bone marrow disorders may be involved, so testing to pinpoint the exact cause is important. If anemia symptoms persist, see a doctor to identify the precise cause.

What anemia is

Anemia is often dismissed as simple dizziness, but management can vary greatly depending on the underlying cause. This page is provided for general informational purposes; if anemia is suspected, see a doctor for an exam and blood test to confirm the precise cause.

Its link to stomach conditions

Chronic gastritis or gastrointestinal bleeding can be a cause of iron-deficiency anemia, so if anemia recurs, it is worth also checking on your digestive health.

Frequently Asked Questions

Will taking iron supplements cure anemia right away?

Iron supplementation can help with iron-deficiency anemia, but the effect and timeline vary depending on the cause and how it's taken, so it's important to take it according to a doctor's diagnosis and prescription.

Can men get anemia too?

Yes — anemia is more common in women, but men can also develop it due to chronic illness, digestive tract bleeding, or nutritional deficiency.
