Introduction
Anemia occurs when your blood does not contain adequate healthy red blood cells to properly and effectively perform its functions. It is a common health condition wherein blood flow to one's organs and tissues is lessened. Having diabetes can contribute to developing anemia in several ways. One in four individuals with type 2 diabetes has anemia. Diabetes can often lead to damage to your kidneys, which in turn can fail the kidneys and cause anemia. Healthy kidneys realize when your body needs new red blood cells and release a hormone called EPO, or erythropoietin, which signals the bone marrow to make more cells. Living with this anemia, along with types of diabetes, can create more complications and a greater risk of developing life-threatening consequences.
What Is Anemia, and What Are Its Symptoms?
Anemia occurs when your body does not have an adequate amount of red blood cells or hemoglobin within the blood. Hemoglobin is a kind of protein through which the RBCs transport oxygen from your lungs to the other parts of your body. When someone does not get enough red blood cells or hemoglobin, their body tissues will not receive the oxygen they need. These may lead to symptoms like pale appearance of skin, fatigue, shortness of breath, palpitations, giddiness, dizziness, headache, subnormal body temperature, and cold hands and feet. Iron deficiency anemia is the most common nutritional anemia affecting people worldwide due to micronutrient deficiency.
Some symptoms of IDA are impaired immune system, fatigue, tiredness, and diminished cognitive functioning among children. Anemia in diabetic individuals with CKD results from one or more mechanisms. These, in turn, include vitamin deficiencies, such as folate and B12, though quite rare. Major causes of anemia in people with CKD include deficiencies in iron and erythropoietin, together with hyporesponsiveness to the actions of erythropoietin. Anemia can range from mild to severe depending on the level of your red blood cells and hemoglobin within the blood. The chances of anemia are also possible if you have diabetes.
You must consult and follow up with your healthcare provider so that the condition can be monitored regularly. The doctor might monitor hemoglobin, a kidney function test, and blood sugar levels to alter your treatment plan accordingly. Healthcare providers may recommend blood transfusions or erythropoietin injections to raise the blood's level of red blood cells.
How Does Diabetes and Anemia Relate to Each Other?
Anemia is a complication in diabetic patients and those more likely to develop CKD or failing kidneys. Early stages of kidney disease can be asymptomatic but can be recognized along with anemia and diabetes. This can, therefore, be a warning bell that your kidneys are malfunctioning. In addition to that, some other complications related to diabetes can occur, which include, but are not restricted to, issues relating to retinopathy and neuropathy. And lastly, kidney, heart, and artery health deteriorates. The sudden surge in the inflammatory cytokines plays an important role in your insulin resistance, evidenced by the development of cardiovascular complications and kidney diseases through an increase in interleukin -6
This interleukin -6 decreases the sensitivity of progenitors to erythropoietin and increases its apoptosis, resulting in immature erythrocytes.
According to research studies, kidney diseases affect diabetic patients, amounting to 40 percent. These renal dysfunction and pro-inflammatory cytokines are, in fact, the most influential and crucial determinants that affect and decide on the reduction of hemoglobin. The inflammatory situation created by the kidney can impede iron absorption from the intestines and impair iron mobilization, further causing injury and increasing vulnerability to anemia. Some antidiabetic drugs also reduce the amount of the protein hemoglobin. It is used to carry oxygen throughout your blood. The antidiabetic drugs that provide an impact on them are:
-
Metformin: This is the most common drug used for diabetes control. Metformin causes malabsorption of vitamin B12, and its long-term use leads to a deficiency in vitamin B12. Its deficiency causes anemia.
-
Fibrates: These drugs are applied to lower triglycerides and your LDL.
-
Thiazolidinediones: Sometimes TZDs or glitazones can lower insulin resistance in people with type 2 diabetes.
-
Angiotensin-Converting Enzymes: ACE inhibitors can relax your blood vessels, helping improve blood flow and lower your blood pressure. These medications can also be prescribed for CKD and diabetes.
-
As the root cause of anemia is blood loss, then diabetic and kidney dialysis patients are at more risk of getting anemia.
How Is Diabetes Anemia Treated?
The treatment regarding anemia with diabetes includes:
-
Iron-rich diet or iron supplement. Iron-rich foods include beans, lentils, liver, oysters, tofu, meat, fish, dried fruits, red meat, raisins, and apricots.
-
If metformin depletes your iron, discuss with your provider whether to change or adjust medication or dosage.
-
If you are receiving kidney dialysis, the optimal route to get iron is directly into a vein through injections. This may help improve your hemoglobin level but also enhance the chance of stroke and heart attack.
-
Therefore, if the kidneys are damaged and their production of this hormone is affected, it is better to take a synthetic form of hormone that promotes the production of red blood cells. This may result in normal levels of red blood cells. Nearly five to ten percent of people on rhEPO develop resistance to this medicine.
-
You may have to be transfused with blood if the anemia is more severe. Treatment in most cases is based on the condition's root cause but may also include supplementing with vitamin B or iron.
Conclusion
A strong association exists between anemia and diabetes, though neither causes the other. Diabetic complications like inflammation of the blood vessels, kidney disease, or even renal failure may cause anemia. A few diabetic medications are also known to increase your risk of developing anemia. Iron supplementation lowers HBA1c in non-diabetic and diabetic individuals. That means that iron must be considered in interesting HbA1c concentrations. Early diagnosis and treatment may improve their glycemic control and prevent or delay their complications. Furthermore, anemia can contribute to more difficult diabetic management; higher A1C results in high sugar in the blood, which may further raise your chance of worsening organ health that leads to future diabetic complications.
