What Nutritional Supplements Help Raise Hemoglobin Levels?
You can live days without water and weeks without food. Lack of oxygen, however, kills within minutes. Hemoglobin is the vital protein in your red blood cells that transports oxygen from your lungs to your tissues. A low hemoglobin level compromises oxygen delivery to your tissues. Many conditions and diseases can cause a low hemoglobin level, or anemia, including certain nutritional deficiencies. Supplements can help to raise a low hemoglobin level caused by a nutritional deficiency, but they will not correct anemia due to another underlying cause. Video of the Day Iron deficiency is the most common cause of anemia in the United States. You may develop an iron deficiency from inadequate nutritional intake, reduced intestinal absorption or blood loss. Microscopic examination of your blood and tests to measure your iron stores help your doctor determine whether you have a deficiency. Iron supplements and an iron-rich diet are standard treatments for mild to moderate iron-deficiency anemia. Your doctor may recommend a blood transfusion, iron shots or intravenous iron if you have a critically low hemoglobin level. Vitamin B-12 Your hemoglobin level and red blood cell count may drop to abnormally low levels with a vitamin B-12 deficiency. Vitamin B-12 deficiency anemia is also known as pernicious anemia and megaloblastic anemia. Your diet may not contain enough vitamin B-12, especially if you follow a strict vegan nutrition plan. Poor absorption of vitamin B-12 can also cause megaloblastic anemia. Your doctor will request blood tests to determine if a B-12 deficiency is responsible for your anemia. Other tests may also be needed. Your doctor may prescribe vitamin B-12 shots, oral supplements, or both, to treat your condition and raise your hemoglobin to a normal level. Fola Continue reading >>

Case Report Falsely Decreased Hba1c In A Type 2 Diabetic Patient Treated With Dapsone
Glycated hemoglobin A1c (HbA1c) is an important indicator of glycemic control. The current recommendation for glycemic control based on HbA1c values has been widely accepted. However, HbA1c values depend on the lifespan of erythrocytes and the assay methods used. Here, we report the case of a patient with type 2 diabetes with unusual falling of HbA1c due to interference from dapsone treatment for leukocytoclastic vasculitis. He was a 52-year-old man, who was diagnosed with type 2 diabetes mellitus 5 years previously and who had been treated in our hospital in the past 3 years. Glycemia was controlled by sulfonylurea and metformin. During the 3-years follow-up period, HbA1c dropped significantly during the addition of dapsone treatment, although plasma glucose levels remained stable. HbA1c levels were raised after discontinuation of dapsone. With rechallenge of dapsone usage, HbA1c decreased again. We conclude that dapsone may be the cause of artificially low HbA1c. Other measurements to monitor glycemic control should be considered when dapsone is used for the treatment of concurrent disorders, such as autoimmune disease and pneumocystis jiroveci pneumonia.

Factors That Interfere With Hba1c Test Results
Information for physicians and patients regarding HbS, HbC, HbE and HbD traits More about hemoglobin variants and HbA1c can also be found at the NIDDK web site: Sickle Cell Trait and Other Hemoglobinopathies and Diabetes: Important Information for Physicians For People of African, Mediterranean, or Southeast Asian Heritage: Important Information about Diabetes Blood Tests Factors that Interfere with HbA1c Measurement: Genetic variants (e.g. HbS trait, HbC trait), elevated fetal hemoglobin (HbF) and chemically modified derivatives of hemoglobin (e.g. carbamylated Hb in patients with renal failure) can affect the accuracy of HbA1c measurements. The effects vary depending on the specific Hb variant or derivative and the specific HbA1c method. Table 1 contains information for most of the commonly used current HbA1c methods for the four most common Hb variants, elevated HbF and carbamylated Hb. Interferences from less common Hb variants and derivatives are discussed in Bry, et al . All entries in Table 1 are based on published information. In addition, if a product insert indicates clearly that there is inference from a particular factor, then the interference is entered as “yes” and the product insert is cited. When selecting an assay method, laboratories should take into consideration characteristics of the patient population served, (e.g. high prevalence of hemoglobinopathies or renal failure). Factors that affect interpretation of HbA1c Results: Any condition that shortens erythrocyte survival or decreases mean erythrocyte age (e.g., recovery from acute blood loss, hemolytic anemia) will falsely lower HbA1c test results regardless of the assay method used . HbA1c results from patients with HbSS, HbCC, and HbSC must be interpreted with caution given the patholog Continue reading >>
Diabetes And Anemia: Are They Related?
Someone’s anemic if they have an abnormally low amount of red blood cells – and when there are too few red blood cells, body organs don’t get the oxygen they need. This not only strains and damages organs, but it also decreases a person’s quality of life by causing fatigue, weakness, and headaches. Red blood cells can transport oxygen because they’re full of a complex molecule called hemoglobin, which can grab, hold, and release oxygen as needed in different part of the body. A doctor may an anemic person as having “too little hemoglobin” or “a low hematocrit”. The first statement refers to the amount of concentration of hemoglobin molecules in your blood, and the second refers to the concentration of red blood cells in your blood. If that sounds redundant, you’re right! They’re both describing the same thing. That’s why it’s best to pay attention to one or the other (not both) to avoid confusion. Types of anemia There are quite a few different types of anemia (over 400 to be exact!). The most common ones are summarized below. It is very important to know the type of anemia and the cause. Without knowing the cause, you cannot treat the disease! Iron Deficiency. This is the most common type. It is caused by lack of absorption, intake, or by blood loss. Aplastic. This occurs when the body stops making new red blood cells. It is rare, but very serious. Hemolytic. This type happens when red blood cells are destroyed faster than they can be produced. Vitamin Deficiency. Poor nutrition, or impaired vitamin absorption causes this type. Pernicious. With this, the B-12 intake is okay, but the body cannot process it correctly. Fragile Red Cell. Some people inherit abnormal red blood cells that die earlier than normal, like in sickle cell or thalassemia. Continue reading >>
High A1c In Some Subjects May Not Indicate Prediabetes
A new study has shown that for people with iron-deficiency anemia, elevated A1c’s may not reflect glycemic parameter.… "The use of HbA1c to diagnose prediabetes and diabetes in iron-deficient populations may lead to a spuriously exaggerated prevalence," the researchers cautioned in their published report. Dr. Chittaranjan S. Yajnik of King Edward Memorial Hospital Research Center in Pune, India, wrote that, "A1c concentration depends not only on prevailing glycemia but also the life span of erythrocytes." "Iron deficiency increases erythrocyte survival and therefore disproportionately elevates HbA1c concentrations at a given glycemic level," they note. It the current study, the team studied 116 young adults enrolled in a longitudinal cohort study. Among this group, 34% were anemic, 37% were iron deficient, 40% were vitamin B12 deficient, and 22% were folate deficient, the authors note. Prediabetes was prevalent in 7.8% and diabetes in 2.6%, based on a standard oral glucose tolerance test (OGTT), while corresponding rates based on American Diabetes Association HbA1c criteria were 23.3% for prediabetes and 2.6% for diabetes, the researchers found. "A total of 24 participants who were normoglycemic by OGTT criteria were misclassified as having prediabetes or diabetes by HbA1c criteria, and six prediabetic or diabetic participants were misclassified as normal by HbA1c criteria," they report. On further analysis, HbA1c was predicted not only by higher glycemia but also by lower ferritin, the report indicates. "Our results support a substantial nonglycemic nutritional influence on HbA1c concentrations in young nondiabetic Indians," Dr. Yajnik and colleagues conclude. "This complicates the use of HbA1c in the diagnosis of prediabetes in nutritionally compromised population Continue reading >>
Metformin And Risk For Vitamin B12 Deficiency
Metformin (brand names Glucophage, Glucophage XR, Fortamet, Riomet, Glumetza, and others) is a popular and highly effective oral diabetes drug used to help manage Type 2 diabetes. This drug works by lowering the amount of glucose made by the liver and by making the body’s cells more sensitive to insulin. Metformin also has some other beneficial effects in that it may help lower blood lipid, or fat, levels (cholesterol and triglycerides) and can, in some people, promote a small amount of weight loss. Metformin can be used with other diabetes pills and with insulin. Side effects of taking metformin are relatively rare, the most common being bloating, nausea, and diarrhea, all of which are temporary. Some people shouldn’t take metformin, including people with kidney disease, liver disease, or congestive heart failure, for example, because of an increased risk of a potentially fatal condition called lactic acidosis. In recent years, there’s been some concern over the risk of vitamin B12 deficiency in people who take metformin. Vitamin B12 (also known as cyanocobalamin or cobalamin) plays many important roles in the body, such as keeping your blood cells and nervous system in tip top shape. There’s also some evidence that vitamin B12 may help prevent heart disease and possibly even Alzheimer disease (the jury is still out on this one). This vitamin is found primarily in animal foods, such as beef, seafood, eggs, and dairy products, which is why some vegetarians are at risk for a B12 deficiency. Elderly people are often at risk for deficiency as well, due to problems with absorption from the gastrointestinal tract. Symptoms of B12 deficiency include certain types of anemia, neuropathy, memory loss, confusion, and even dementia. So, why would taking metformin possibly Continue reading >>
Anemia is a sign of an underlying issue with red blood cells (RBCs) and their ability to carry oxygen to tissues, resulting in hypoxia. It occurs when the total number of red cells is low or the amount of hemoglobin is low. Hemoglobin is the protein that carries oxygen on RBCs. Looking for the root cause of anemia is essential to determine the appropriate treatment.  Naturopathic Assessment In order to stimulate the innate ability of the body to heal the causes of disease must be identified and addressed. With anemia, the causes are variable. A detailed assessment is required to determine which factors are contributing. Generally there are three main causes of anemia: excessive blood loss (heavy menses, hemorrhage or chronic low-volume loss), easy destruction of red blood cells (hemolysis) or deficient production of red blood cells (ineffective hematopoiesis). Inadequate nutritional intake of iron, Vitamin B12 or folate; especially in developing countries or malnutrition in general can cause an inadequate production of red blood cells. Skipping lunch and diets with low amounts of poultry and fish have been associated with increased risk of anemia.  Economic Status Low socioeconomic status is commonly associated with nutritional deficiency which causes 50% of all anemia especially in school aged children leading to chronic anemia. Altitudes Medical Procedures Prescription Medications Salicylates such as aspirin or willow bark can lead to iron deficiency and anemia due to blood loss from hemorrhage. Thalassemias are inherited disorders involving the four chains of protein that make up hemoglobin. There are two alpha chains and two beta chains therefore four possible subsets of Thalassemia depending on the degree of inheritance of affected genes. Thalassemia Continue reading >>
Macrocytic Anemia Is A Sign That Something Is Wrong!
Macrocytic Anemia, also called Macrocytosis, is a condition of larger, oddly shaped and fewer red blood cells that occurs for a variety of reasons. Primarily this shows up on a blood test by a high number on the MCV Blood Test that is a portion of the Complete Blood Count- or CBC test- which is part of most routine blood tests. The condition gets its name from how it appears on the blood test. The word 'Macro' means large, as in a 'macro' lens on a camera. The prefix 'cy' or 'cyto' means cell and the word 'anemia' refers to any condition of fewer red blood cells or hemoglobin. Hence the word Macrocytic Anemia or macrocytosis. Macrocytic anemia is most often caused by an individual problem or a combination of problems such as: Alcoholism Folic Acid Deficiency Vitamin B6 Deficiency Malabsorption Problems such as Gluten Sensitivity or drug side effects such as: But regardless, a high MCV should prompt further investigation by your doctor into WHY you have this problem. However, it's VERY often the case that a high MCV blood test gets overlooked as not being significant- when it can be EXTREMELY significant to your health. In fact, when you begin Understanding Blood Test Results, you'll see that the finding of Macrocytosis can indicate serious conditions that have been causing your health problems for YEARS and are only now showing up on your blood test! If you have had chronic health conditions, macrocytic anemia could finally show what your problem has been all of this time. But ONLY if your doctor is vigilant about looking into the causes of macrocytic anemia and seeing it as the problem of serious nutritional deficiencies that it is- unfortunately, most doctors DON'T see it this way and don't understand about the serious health implications of the underlying causes of t Continue reading >>
Pernicious Anemia And Vitamin B-12 Deficiency
Pernicious anemia is defined as a type of vitamin B12 deficiency that results from impaired uptake of vitamin B-12 due to the lack of a substance known as intrinsic factor (IF) produced by the stomach lining. Pernicious anemia is a condition caused by too little vitamin B12 in the body. It is one form of vitamin B12 deficiency anemia. Vitamin B12 helps the body make healthy red blood cells and helps keep nerve cells healthy. It is found in animal foods, including meat, fish, eggs, milk, and other dairy products. The most common cause of pernicious anemia is the loss of stomach cells that make intrinsic factor. Intrinsic factor helps the body absorb vitamin B12 in the intestine. The loss of parietal cells may be due to destruction by the body's own immune system. Pernicious anemia can cause permanent damage to nerves and other organs if it goes on for a long time without being treated. It also raises the risk for developing stomach cancer. Common signs and symptoms of vitamin B12 deficiency, seen in pernicious anemia are: Feeling tired and weak Tingling and numbness in hands and feet A bright red, smooth tongue Pernicious anemia is diagnosed using family history and medical history, a physical exam, and diagnostic tests and procedures. Pernicious anemia is easy to treat with vitamin B12 pills or shots as well as diet changes. Life-long treatment is needed. Complications caused by untreated pernicious anemia may be reversible with treatment. Doctors don't know how to prevent pernicious anemia that is caused by the immune system destroying stomach cells. Eating foods high in vitamin B12 and folic acid can help prevent vitamin B12 deficiency caused by a poor diet. Continue reading >>
Effect Of Iron Deficiency Anemia On The Levels Of Hemoglobin A1c In Nondiabetic Patients.
Abstract The major form of glycohemoglobin is hemoglobin A1c (HbA1c). The HbA1c fraction is abnormally elevated in chronic hyperglycemic diabetic patients and correlates positively with glycemic control. Previous studies suggest that iron deficiency anemia (IDA) affects the levels of HbA1c. The aim of this study was to determine the effect of IDA on HbA1c levels in nondiabetic patients. The population studied consisted of 50 patients (30 women, 20 men, mean age 35.7 +/- 11.9 years) with IDA and 50 healthy subjects that were matched for age and sex. Patients who had glucose tolerance abnormalities (impaired glucose tolerance or diabetes mellitus), hemoglobinopathies, hemolytic anemia, chronic alcohol ingestion and chronic renal failure were excluded from the study. Hematologic investigations, fasting and postprandial glucose and HbA1c levels were measured in all subjects before iron therapy. All patients with IDA were treated with iron 100 mg/day for 3 months. We repeated the laboratory investigation after iron therapy. Before iron treatment, the mean HbA1c (7.4 +/- 0.8%) level in patients with IDA was higher than in a healthy group (5.9% +/- 0.5) (p < 0.001). In patients with IDA, HbA1c decreased significantly after iron treatment from a mean of 7.4% +/- 0.8 to 6.2% +/- 0.6 (p < 0.001). Iron deficiency must be corrected before any diagnostic or therapeutic decision is made based on HbA1c. Continue reading >>
Reference Ranges For Hemoglobin A1c:
Laboratory reference range: 4.8–5.6% Functional reference range: 4.6–5.3% DESCRIPTION: Hemoglobin A1c is a subtype of hemoglobin that is non-enzymatically glycosylated by circulating glucose. The action of hemoglobin A1c is indistinguishable from other subtypes of hemoglobin; however, measuring levels of hemoglobin A1c in the blood is useful for estimating average levels of blood glucose over a three-month period. Therefore, hemoglobin A1c can be used to inform diabetes mellitus diagnosis and monitor the efficacy of exercise, dietary management, and treatment of diabetes.1 Hemoglobin in newly formed red blood cells contains negligible amounts of covalently bound glucose, yet glucose can freely permeate the cell membranes of red blood cells.1 Thus, glucose can freely interact with hemoglobin molecules within red blood cells. The N-terminus of the beta chain of hemoglobin non-covalently interacts with glucose, then proceeds through a Schiff base and Amadori rearrangement to form a covalent bond between glucose and hemoglobin.2 Over the following weeks, these Amadori rearrangement products transition to intermediate and advanced glycosylation endproducts.3,4 These reactions are irreversible and persist for the life of the red blood cell. This non-enzymatic covalent bonding of glucose and hemoglobin takes place in a dose-dependent fashion, such that greater amounts of circulating glucose correspond to higher levels of glycosylated hemoglobin, or hemoglobin A1c. The typical lifespan of a red blood cell is 120 days, with approximately 1 percent of the entire erythrocyte population degrading and replenishing itself daily.1,5 Taken together, this indicates that any spot assessment of hemoglobin A1c level in the blood provides an average circulating glucose level for the pre Continue reading >>
Vitamin B12 Deficiency
Also known as Cobalamin Deficiency and Cyanocobalamin Deficiency Vitamin B12 deficiency or hypocobalaminemia is a low blood level of vitamin B12. It can cause permanent damage to nervous tissue if left untreated longer than 6 months. Vitamin B12 itself was discovered through investigation of pernicious anemia, which is an autoimmune disease that destroys parietal cells in the stomach that secrete intrinsic factor. Pernicious anemia, if left untreated, is usually fatal within three years. Once identified, however, the condition can be treated successfully and with relative ease, although it cannot be cured and ongoing treatment is required. Humans obtain almost all of their vitamin B12 from dietary means. Pernicious anemia is usually the result of insufficient secretion of intrinsic factor within the stomach. Other more subtle types of vitamin B12 deficiency have been elucidated, including the biochemical effects, over the course of time in significant numbers. Source: Wikipedia What are the symptoms? Within all the people who go to their doctor with vitamin b12 deficiency, 36% report having fatigue, 14% report having disturbance of memory, and 14% report having paresthesia. The symptoms that are highly suggestive of vitamin b12 deficiency are abnormal appearing tongue, although you may still have vitamin b12 deficiency without those symptoms. Continue reading >>
Effect Of Iron Deficiency Anemia On Hemoglobin A1c Levels
Go to: Abstract Background Iron deficiency anemia is the most common form of anemia in India. Hemoglobin A1c (HbA1c) is used in diabetic patients as an index of glycemic control reflecting glucose levels of the previous 3 months. Like blood sugar levels, HbA1c levels are also affected by the presence of variant hemoglobins, hemolytic anemias, nutritional anemias, uremia, pregnancy, and acute blood loss. However, reports on the effects of iron deficiency anemia on HbA1c levels are inconsistent. We conducted a study to analyze the effects of iron deficiency anemia on HbA1c levels and to assess whether treatment of iron deficiency anemia affects HbA1c levels. Fifty patients confirmed to have iron deficiency anemia were enrolled in this study. HbA1c and absolute HbA1c levels were measured both at baseline and at 2 months after treatment, and these values were compared with those in the control population. The mean baseline HbA1c level in anemic patients (4.6%) was significantly lower than that in the control group (5.5%, p<0.05). A significant increase was observed in the patients' absolute HbA1c levels at 2 months after treatment (0.29 g/dL vs. 0.73 g/dL, p<0.01). There was a significant difference between the baseline values of patients and controls (0.29 g/dL vs. 0.74 g/dL, p<0.01). Conclusions In contrast to the observations of previous studies, ours showed that HbA1c levels and absolute HbA1c levels increased with treatment of iron deficiency anemia. This could be attributable to nutritional deficiency and/or certain unknown variables. Further studies are warranted.

Glucose 6 Phosphate Dehydrogenase Deficiency
Glucose - 6 - phosphate dehydrogenase -LRB- G - 6 - PD -RRB- deficiency is a hereditary condition in which red blood cells break down when the body is exposed to certain drugs or the stress of infection . Overview Persons with this condition do not display any signs of the disease until their red blood cells are exposed to certain chemicals in food or medicine , or to stress.Symptoms are more common in men and may include : Dark urineEnlarged spleenFatiguePalenessRapid heart rateShortness of breathYellow skin color -LRB- jaundice -RRB- Symptoms Treatment may involve : Medicines to treat an infection , if presentStopping any drugs that are causing red blood cell destructionTransfusions , in some cases Treatment G6PD deficiency occurs when a person is missing or does n't have enough of an enzyme called glucose - 6 - phosphate dehydrogenase , which helps red blood cells work properly.Too little G6PD leads to the destruction of red blood cells . A type of anemia (red blood cell deficiency) caused by the premature destruction of red blood cells. I shudder to think what may have become of me. [b]VERY IMPORTANT:[/B] Apparently, they have discovered that 10% of the population is either missing a certain liver enzyme or has a deficiency of this enzyme. This process is called hemolysis .

Dr. Roach: Though Rare, Medication Can Be Cause Of Ed
Dear Dr. Roach: I am a 77-year-old man who has had erectile dysfunction for eight years. I have been on the following medications for over 12 years: atenolol, lisinopril and amlodipine for high blood pressure; metformin and glipizide for Type 2 diabetes. Recent lab results have shown normal testosterone level, A1C reading of 6 and BP of 128/78. Could there be a relationship between my medications and my ED? — R.F. Answer: Erectile dysfunction is a common problem in men, and is increasingly prevalent as men get older. Sometimes a cause is found, but often there isn’t. When there is a cause that’s found, it sometimes is due to medicine, but also can be traced to poor blood flow, damage to nerves, abnormal hormone levels or psychological factors. Poor blood flow in large blood vessels can cause ED. This means treatment is important, because men with blockages in the blood supply to the penis also may have blockages in the blood supply to the heart or brain, so it’s worth considering. Men with high blood pressure and diabetes are at higher risk for arterial blockages. Nerve damage can be due to trauma or nerve diseases. Diabetes increases the risk of all kinds of nerve diseases, but your A1C level indicates that you have good control of your diabetes, which makes this unlikely. A careful physical exam can answer this question. Testosterone levels frequently are abnormal in older men, but one other hormone I recommend checking in men with ED is prolactin: It can be a cause of ED, although rare. It can be produced by brain tumors. Psychological factors are the hardest to diagnose, but many of us physicians forget to even ask. If there are no clear reasons for ED, then I certainly would evaluate the medicines you are taking. Of your medications, atenolol is the most of Continue reading >>
