Expert Commentary
Iron deficiency anemia (IDA) is a common condition in patients with non–dialysis-dependent chronic kidney disease (NDD-CKD) that can affect quality of life and exacerbate morbidity. Despite the impacts of IDA in NDD-CKD patients, its screening, diagnosis, and treatment remains challenging. This educational hub will aim to increase awareness about IDA in this setting, as well as provide informational resources to clinicians about risk factors, diagnosis, and treatment of IDA in NDD-CKD patients.

IDA IN NDD-CKD WHAT YOU SHOULD KNOW
What Is Iron Deficiency? Iron deficiency (ID) means a shortage of iron, and without enough of it, the
HOW IS IDA IN NDD-CKD DIAGNOSED AND TREATED?
Diagnosis Your doctor can check your hemoglobin (Hb) levels with a blood test. Hb is a protein
Without adequate iron, the body's red blood cells cannot provide enough oxygen to our tissues and organs, resulting in ID. A frequent consequence of CKD is iron-deficiency anemia (IDA). You might have reduced iron levels if you have CKD. Many patients with CKD also experience blood loss that results in iron shortage, particularly if they are receiving dialysis for their renal failure. Due to infections, inflammation, and malnutrition, patients with CKD frequently experience problems with iron absorption.

Lack of iron in the diet (for example a vegan diet or malnutrition), problems with iron absorption in the stomach, increased blood loss, and an increased need for iron can all contribute to IDA.

Extreme exhaustion, shortness of breath, pale skin, brittle fingernails, body aches and a weak feeling, headaches, dizziness, fainting, heart palpitations, chest pain, disturbed sleep, and difficulty focusing are possible symptoms of IDA.

Our bodies need iron to make hemoglobin (Hb). Hb contains iron, which allows it to bind to oxygen. Hb enables your red blood cells to carry oxygen from your lungs to other tissues and organs throughout your body.

Doctors can suspect IDA from your symptoms. If IDA is suspected, a simple blood test can check the level of Hb in your blood. If your Hb is low, then this indicates that iron levels are low, and IDA can be diagnosed. The World Health Organization defines anemia as a Hb concentration of less than 12.0 g/dL in women and less than 13.0 g/dL in men.

Iron is poorly absorbed from our stomachs and intestines. Most of the iron we take orally is not absorbed into our bodies and can cause side effects. Many people who take iron tablets or capsules get an upset stomach, constipation, or heartburn.
If your iron levels are low and you have kidney disease, iron injections are recommended over iron tablets or capsules because of its fast absorption into your body and less side effects.

You can increase your iron by eating foods that are rich in iron. It is recommended that you eat an iron-rich diet, which includes foods like meat and leafy green vegetables. There are plenty of other foods that are rich in iron and other foods that contain vitamin C, that help your body to absorb iron more effectively. If your iron levels are slightly low, then your doctor may recommend you increase iron in your diet. If your iron levels are very low and you have IDA, then it may take too long to increase your iron levels through diet alone. An injection with iron can restore your iron levels quickly, reducing the symptoms of IDA more efficiently.
