Why Are Diabetic Patients at Higher Risk of Anaemia?

Multiple factors contribute to anaemia among people with diabetes:

Chronic inflammation, common in diabetes, is central to the development of iron deficiency anaemia.
Diabetic kidney disease and chronic kidney disease are common in diabetes and contribute to anaemia by impairing erythropoietin synthesis, a hormone essential for red blood cell formation.
Micronutrient deficiencies in iron, vitamin B12, folate, and others are frequent in diabetic populations, partly due to dietary patterns and medication effects (e.g., metformin can reduce B12 absorption)
Gender differences exist, with women with diabetes showing a higher prevalence of anaemia than men.
Coexisting conditions such as hypertension, cardiovascular disease, and gastrointestinal disorders may further impair nutrient absorption.
Duration of diabetes matters, as individuals living with diabetes for over 20 years face a significantly higher risk of developing anaemia.

3 Steps To Increase Haemoglobin in Diabetic Patients

If you’re managing diabetes and low haemoglobin, here’s a structured approach to consider in consultation with your healthcare provider:

1. Assess and Address Nutritional Deficiencies

Iron supplementation: Oral or intravenous iron can help correct iron-deficiency anaemia and raise haemoglobin levels. Some formulations, such as ferrous bisglycinate, may be better tolerated in the long term than traditional iron salts.
Balanced diet: Anaemia prevalence among vegetarian diabetic patients is nearly two-fold higher than in non-vegetarian diabetics.

2. Optimise Diabetes Control
Good glycemic control reduces inflammation and microvascular stress that contribute to anaemia.

3. Lifestyle Support
Regular physical activity, adequate sleep, and hydration create a healthier environment for your body to naturally produce haemoglobin.

Managing Haemoglobin for Better Diabetes Outcomes

Keeping your haemoglobin in a healthy range matters not just for energy, but also for reducing diabetes-related complications. Working with your healthcare team to create a plan that covers diet, supplements, and chronic disease management can make a real difference in your quality of life.
