About Vitamin Deficiency Anemia
Vitamin deficiency anemia occurs when there is a lack of certain vitamins in the body, which can lead to low levels of healthy red blood cells.
Causes of vitamin deficiency anemia:
- Inadequate dietary intake: Not consuming enough foods that contain essential vitamins, such as vitamin B1, folate and vitamin D.
- Poor absorption: Certain medical conditions like celiac disease, ulcerative colitis, Crohn's disease, and conditions affecting vitamin B12 absorption can interfere with the body's ability to absorb vitamins properly.
- Medications: Some medications, like metformin and proton pump inhibitors, can limit the absorption of vitamin B12.
Non-modifiable risk factors are risk factors that cannot be changed. Non-modifiable risk factors of vitamin deficiency anemia:
- Age: As we age, our bodies may have a harder time absorbing and utilizing vitamins.
- Gender: Although it affects people of all genders, some studies have shown that women may be at a higher risk for certain types of anemia.
- Family history: Having a family history of anemia or certain medical conditions that affect vitamin absorption may increase the risk.
- Autoimmune and gastrointestinal disorders: Pernicious anemia, Crohn’s and celiac disease can interfere with the absorption of vitamin B12.
Modifiable risk factors are risk factors that can be changed or influenced. Modifiable risk factors of vitamin deficiency anemia:
- Poor diet
- Following a vegan or vegetarian diet without proper supplementation
- Not getting enough sun exposure
- Excessive consumption of alcohol use
- Use of certain medications
- Gastric bypass surgery (a type of weight-loss surgery) can change the ability to absorb vitamins and other nutrients
The symptoms of vitamin deficiency anemia can vary depending on the stage, progression, or severity of the condition. Here are the most common early symptoms of vitamin deficiency anemia:
- Fatigue (feeling tired and lacking energy)
- Weakness
- Headaches
- Pale skin
- Tingling or numbness
- Nausea
- Decreased appetite
Other common symptoms that may occur with later stages, progression, or higher severity of vitamin deficiency anemia:
- Difficulty breathing or feeling breathless
- Chest pain
- Unintentional weight loss
- Easily becoming annoyed or agitated
- Diarrhea
- Sore and tender tongue
- Fast heart rate
- Difficulty walking
- Vision problems
- Memory problems
- Depression
To diagnose vitamin deficiency anemia, doctors typically perform a series of examinations, tests, and procedures. These include:
- Medical history: The doctor will ask about your medical history, including any symptoms you may be experiencing and any family history of anemia.
- Physical examination: During a physical exam, the doctor will look for signs of anemia, such as pale or yellowish skin and a rapid pulse.
- Complete blood count (CBC): This blood test measures the number of red blood cells, white blood cells, and platelets in your blood. It can help identify abnormalities in red blood cells and the amount of hemoglobin present.
- Vitamin B12 level test: This blood test measures the amount of vitamin B12 in your blood. Low levels of vitamin B12 can indicate a deficiency.
- Serum ferritin levels: This blood test measures the amount of iron stored in your body. Iron is essential for the production of healthy red blood cells.
- Serum iron levels: This blood test measures the amount of available iron in your body. Low levels of iron can contribute to anemia.
- Folate test: This blood test checks for low levels of folate, which can cause macrocytic anemia.
In some cases, additional examinations, tests, and procedures may be necessary to determine the stage or severity of vitamin deficiency anemia. These can include:
- Reticulocyte count: This blood test measures the number of immature red blood cells in your blood. It can help determine how well your bone marrow is producing new red blood cells.
- Intrinsic factor and parietal cell antibodies: In cases where pernicious anemia is suspected as the cause of Vitamin B12 deficiency, these tests check for antibodies against intrinsic factor and stomach parietal cells. In pernicious anemia, autoantibodies destroy the cells that produce intrinsic factor, which is necessary for absorbing vitamin B12.
- Bone marrow tests: In some cases, bone marrow tests may be performed to assess if your bone marrow is producing red blood cells properly.
By conducting these examinations, tests, and procedures, doctors can diagnose vitamin B12, vitamin D and folate deficiency anemia and determine its stage or severity if necessary.
The goals of treatment for vitamin deficiency anemia are to increase the levels of vitamin B12, vitamin D or folate in the body, improve the red blood cell count, and relieve symptoms. Here are the different types of treatments and therapies recommended for vitamin deficiency anemia:
- Vitamin supplements:
- Taking oral vitamin B12 supplements or receiving vitamin B12 injections can help reverse the deficiency and increase vitamin B12 levels in the body. These supplements can be prescribed by a doctor and are taken by mouth, as a nose spray, or as a shot.
- Folate supplements are usually taken orally to help increase levels of folate in the body and reverse symptoms of anemia from folate deficiency.
- Vitamin D supplements are usually taken orally to help increase levels of vitamin D in the body and reverse symptoms of anemia associated with vitamin D deficiency.
- Dietary changes: Making changes to your eating habits can also help increase the amount of needed vitamin in your diet.
- Including foods that are rich in vitamin B12, such as meat, fish, eggs, and dairy products, can be beneficial.
- Eating lots of dark leafy greens, beans, citrus fruits, seafood, eggs, poultry and dairy will help increase folate levels. Some cereals, breads and pastas may be fortified with folate.
- Foods that are naturally rich in vitamin D include fatty fish (examples are salmon, mackerel, and sardines), egg yolks, beef liver, and mushrooms. Some cereals, milk, and orange juice may be fortified with vitamin D.
- Blood transfusions: In cases of severe vitamin deficiency anemia, blood transfusions may be necessary to quickly increase red blood cell count and oxygen levels in the blood.
Some individuals with vitamin B12 or folate deficiency anemia may require lifelong treatment to maintain adequate levels of vitamin B12 or folate in their body. This can involve regular intake of vitamin B12 or folate supplements or injections as prescribed by a healthcare provider.
It's important to note that treatment response may vary among individuals, and some symptoms may take time to improve. Symptoms related to the brain or nerves, such as numbness and tingling, may not completely go away even with treatment. It's important to work closely with a healthcare provider who can determine the most appropriate treatment plan based on individual needs and circumstances.
If left untreated, vitamin deficiency anemia can lead to serious complications. Here are possible complications related to vitamin deficiency anemia.
- Visual disturbances
- Depression
- Confusion
- Problems with concentration, thinking, and memory
- Infertility may develop but is usually reversible
- Pregnant individuals with vitamin deficiency anemia are at risk of giving birth to babies with developmental delays and birth defects of the brain and spinal cord.
- Bleeding
- Increased risk of infections
- Brain and nerve problems
Treatment for vitamin deficiency anemia is crucial to prevent complications. Treating vitamin deficiency anemia can cure the condition, slow its progression, and reduce complications. It's important to consult with a healthcare professional before starting any treatment. They can provide personalized advice based on individual needs.
