Type 1 diabetes is an autoimmune problem. In this, the body’s immune system damages the insulin-producing cells. Insulin is a hormone that aids the cells absorb sugar from the food products a person consumes. As insulin is inadequate in Type 1 diabetes, sugar fails to be used by the body.
This increases its blood level. Certain complications relate to Type 1 diabetes. These include kidney damage. Kidney damage may occur due to iron deficiency. This also changes blood sugar levels. Iron deficiency or anaemia is a medical condition that impacts 20-25% of the population.
Iron is a vital nutrient, and its deficiency relates to reduced quality of life. Discuss with a doctor to regularly check the iron levels if a person is a Type 1 diabetic. Read this blog to learn about the best iron supplements for type 1 diabetics.
Consequences of Iron Deficiency In Type 1 Diabetes
Iron deficiency in people with type 1 diabetes can lead to several adverse health consequences. Without sufficient iron, the body cannot function optimally, leading to a cascade of health issues.
1. Increased Fatigue and Weakness
Iron deficiency can cause anemia, leading to chronic fatigue and weakness. For those with type 1 diabetes, this can exacerbate existing symptoms and impact their ability to manage their condition effectively. Ash Publications stated that iron deficiency has also been associated with cognitive impairment and fatigue, although the strength of these connections is not firmly established. The constant state of tiredness can make it harder to maintain a healthy lifestyle, including regular exercise and proper nutrition, which are critical for diabetes management.
2. Impaired Immune Function
A lack of iron can significantly weaken the immune system, making people with type 1 diabetes more prone to infections. Their bodies may struggle to produce enough white blood cells to fight off pathogens, leading to more frequent and severe infections. This increased susceptibility can complicate diabetes management, as infections can cause blood sugar levels to spike unpredictably.
3. Poor Blood Sugar Control
Iron deficiency can interfere with the body’s ability to metabolize glucose effectively. This can lead to erratic blood sugar levels, making it more challenging for people with type 1 diabetes to maintain stable glucose levels. In a study, NIH found that Iron deficiency (ID) and iron deficiency anemia (IDA) can disrupt how the body regulates glucose, both in animals and humans.
This disruption may worsen blood sugar control and increase the risk of complications in people with diabetes. Such instability increases the risk of both short-term complications, like severe hypoglycemia, and long-term complications, such as cardiovascular disease and nerve damage.
4. Cognitive Impairments
Iron is crucial for brain health, and deficiency can lead to cognitive impairments, such as difficulty concentrating and memory issues. For people with type 1 diabetes, this can affect their ability to manage their condition, as they might struggle with remembering medication schedules, monitoring blood sugar levels, and following dietary guidelines, all of which are essential for effective diabetes management.

Type 1 Diabetes Complications That Increase The Risk of Iron Deficiency
Type 1 diabetes can lead to various complications that increase the risk of iron deficiency. These complications often stem from the disease’s impact on multiple bodily systems, including the kidneys, gastrointestinal tract, and nervous system. Understanding how these complications contribute to iron deficiency is crucial for effective diabetes management and maintaining overall health. Here are some key complications associated with type 1 diabetes that can lead to iron deficiency.
Diabetic Nephropathy
Anemia is a condition characterized by a reduced number of red blood cells (RBCs) in the body. The kidneys produce a hormone called erythropoietin (EPO), which is essential for RBC production. These cells are responsible for transporting oxygen throughout the body. Poorly managed diabetes can damage the kidney’s filtering units, impairing their ability to produce enough EPO. This leads to a decrease in RBC production. Additionally, damaged kidneys often require hemodialysis for blood purification, which can result in the loss of blood and essential nutrients like iron. Consequently, diabetic nephropathy can contribute to anemia and iron deficiency.
Celiac Disease
There is a genetic link between type 1 diabetes and celiac disease, with type 1 diabetes increasing the risk of developing celiac disease. Celiac disease is an autoimmune disorder in which the ingestion of gluten triggers an immune response that damages the small intestine. This damage impairs the absorption of various nutrients, including iron, leading to potential deficiencies.
Autonomic Neuropathy
Fluctuating blood glucose levels can also harm the nerves that control involuntary bodily functions, leading to a condition known as autonomic neuropathy. This condition disrupts the body’s ability to signal the kidneys to produce sufficient erythropoietin. As a result, RBC production is diminished, contributing to anemia.

Signs of Type 1 Diabetes and Iron Deficiency Anemia
As the body receives less oxygen, a person feels weak and fatigued. Some common signs may include:
- Headache
- Dizziness
- Cold feet and hands
- Breathing difficulties
- Pale skin
- Rapid heartbeat
- Low body temperature
- Chest pain
Type 1 Diabetes and Iron Deficiency Anemia Meal Plan
If you are deficient in iron, your doctor may advise iron-rich foods like:
- Iron-fortified cereals
- Squash and pumpkin seeds
- Dried fruits
- Seafood such as sardines, oysters, clams, shrimp
- Beans
- Chicken and beef
- Leafy greens like spinach
- Eggs
Vitamin C improves the absorption of iron. This involves vitamin-C rich food items which improve iron levels. Few sources of vitamin C may include:
- Cauliflower
- Brussels sprouts
- Broccoli
- Fruits including grapefruits, kiwis, oranges, and melons
- Tomatoes
- Green and red bell peppers

Best Ways To Take Iron Supplements for Type 1 Diabetes
Doctors may recommend over-the-counter iron supplements to manage iron deficiency in people with type 1 diabetes. Iron supplements are available in various forms, including liquids, which are particularly suitable for children and infants. The appropriate dosage will be determined by the doctor based on the individual’s specific needs and diagnosis.
To enhance iron absorption, doctors might suggest the following guidelines:
- Avoid taking iron supplements with antacids: Antacids used to manage heartburn can interfere with iron absorption. The Mayo Clinic recommends to take both these supplements atleast 1-2 hours apart.
- Take on an empty stomach: Iron is better absorbed on an empty stomach. However, if this causes stomach upset, it is advisable to take the supplements with meals.
- Take Vitamin C: Vitamin C can significantly enhance iron absorption. Healthcare providers may recommend taking iron supplements with vitamin C or consuming them with orange juice.
Iron supplements can sometimes cause constipation. In such cases, doctors might suggest a stool softener or increasing dietary fiber intake to alleviate this side effect.
To maximize the benefits of iron supplements, avoid consuming certain foods and beverages that can hinder iron absorption, such as:
- High fiber foods
- Antacids
- Caffeine
- Milk
People might start feeling better within a few days of taking iron supplements. However, it is crucial not to discontinue the supplements without consulting a doctor, as it takes several months to replenish the body’s iron stores adequately. Always consult a doctor before starting iron supplements to avoid the risk of iron poisoning from excessive iron accumulation in the blood.

Understanding Iron Levels and Diabetes: Hemochromatosis and Anemia
Iron levels play a crucial role in diabetes management. There are two key iron-related conditions relevant to diabetes: hemochromatosis and iron-deficiency anemia. Let’s break them down for better understanding.
Hemochromatosis
Hemochromatosis is a genetic condition common among people with Celtic ancestry, causing the body to absorb too much iron. Excessive iron can damage various organs, including the pancreatic beta cells, increasing the risk of developing diabetes. In severe cases, this can lead to a condition called “bronze diabetes,” where the skin takes on a bronzed appearance due to high iron levels.
Iron-Deficiency Anemia
Iron-deficiency anemia, on the other hand, is characterized by too little hemoglobin in the blood due to insufficient iron absorption or significant blood loss. Without adequate iron, the body cannot produce enough hemoglobin, leading to a reduced number of red blood cells. This condition can also affect diabetes management, as iron-deficiency anemia can falsely elevate A1C test results, which are used to measure blood sugar levels over time.
Testing for Iron Levels
To diagnose these conditions, doctors use a ferritin test. Ferritin is a protein that stores iron, making it a good indicator of overall iron levels. Low ferritin levels suggest iron-deficiency anemia, while high ferritin levels indicate hemochromatosis.
Impact on A1C Levels
Iron-deficiency anemia can increase A1C values, often seen in late pregnancy due to iron deficiency rather than elevated blood sugar. Treating anemia with iron supplements can lower A1C levels. The exact reason for this is unclear, but it may be related to the lifespan of red blood cells or oxidative stress. Conversely, hemolytic anemia, which shortens the lifespan of red blood cells, can decrease A1C values.
Interpreting A1C Tests
The A1C test assumes an average red blood cell lifespan of 120 days, but this can vary among individuals. This variation can cause A1C results to appear higher or lower than expected, affecting diabetes management.

Conclusion
Iron levels significantly impact health and the accuracy of lab tests used to monitor diabetes. If you receive an abnormal lab result, don’t panic. It’s helpful to repeat the test to rule out errors and investigate potential underlying issues. For those with hemochromatosis or symptoms of anemia (such as rapid heartbeat, fatigue, or pale skin), getting a ferritin test is advisable. Proper diagnosis and treatment of iron-related conditions are essential to manage your diabetes.
FAQ’s(Frequently Asked Questions)
The presence of iron deficiency my cause higher HbA1c values.
A greater risk for iron deficiency may cause anemia. The condition occurs in children with early stages of type 1 diabetes. Anemia in diabetes is not rare and may add to disease complications.
Iron tablets do not cause spikes in the blood glucose levels. Also, a person has to be careful what he or she consumes them with. To aid iron absorption, many doctors advise to take the iron tablets with vitamin C3.
The lipid peroxidation resulting due to an increase in iron storage decreases the usage of sugar in muscle tissue. This increases gluconeogenesis, and results into insulin resistance.
