Chronic Disease Management

What is Megaloblastic Anemia?

It is a type of Anemia disorder (Anemia is a blood disorder characterized by the lower count of Red blood cells) in which the red blood cells size is increased and are not able to exit the bone marrow to enter the bloodstream and deliver oxygen. Without sufficient oxygen supply can result in critical complications like hypoxia and the body doesn’t perform well. The size of the red blood cells is increased in megaloblastic anemia hence it is also called Macrocytic anemia.

The mechanism of Megaloblastic Anemia is the inhibition of DNA synthesis during red blood cell mobile production. When DNA synthesis is blocked so the mitosis process is became stopped and cell growth continues without cell division. Hence the big size cells are produced. 

The main causes of Megaloblastic Anemia are B12 or folate deficiency, Chemotherapy, and some antibiotics. 

Causes of Megaloblastic Anemia

B12 and folate deficiency are the main reasons of Megaloblastic anemia. These nutrients are important for the production of healthful RBCs. we can elaborate on each one here below.

 Vitamins B12 deficiency

Not taking a properly balanced diet can lead to vitamins deficiency.  There are numerous reasons of vitamin B12 deficiency. it could be as a result of the low intake of vitamin B12 containing food plan or due to the lack of intrinsic factors in the stomach, gastric surgical procedures, and some medicines.
Pregnant people are more likely to have a B12 deficiency and they’re commonly at more threat due to the excessive amounts of vitB12 needed by the growing fetus.             

Some people cannot absorb enough vitamin B12 from their diet which leads to Vitamin B12 deficiency.

There is a factor in the stomach called the intrinsic factor which is responsible for the absorption of Vitamin B12. When there is a lack of intrinsic factors it may lead to Anemia which is called Pernicious anemia. Pernicious anemia is one of the forms of megaloblastic anemia.

If someone has done a gastric surgery or by-pass, he/she can face the vitamin b12 deficiency because during surgery the intrinsic factor quantity became decreased.

Some of the medications can also cause the deficiency of Vitamins B12. These are Azathiopurine, Metformin, and proton pump inhibitors.

Folate deficiency.

Folate is also known as folic acid or vitamin B9. That is also an critical component for the production of healthy red blood cells.

Folate deficiency can be caused by the low consumption of Folate from food and misuse of alcohol.

Being pregnant additionally leads to folate deficiency this is why a better amount of folate is required all through pregnancy. A loss of Folate throughout being pregnant can also cause start defects. The remedy of this kind of hassle is to ingest extra folate dietary supplements in foods and medications form.

Natural Sources of Vitamin-B12

The rich sources of vitamin-B12 are the following.


Milk is a terrific source of vitamin-B12 along with other necessary nutrients. 


Egg yolk contains extra quantity of vitamin B12 than eggs white. it’s far really useful that everyone must consume the eggs because they comprise almost each nutrient however humans with excessive cholesterol levels ought to consult the doctor earlier than use.


consequently the vitamin B12 is easily absorbable in dairy products this is why Yogurt is an essential and rich supply of Vitamin-B12.


Salmon is one of the rich assets of Omega-three fatty acids and nutrients.

Liver and Kidney

The liver and kidney comprise vitamins and cholesterol. The heart patient must continually consult his/her medical doctor before ingesting this.

Red meat

beef is also a wealthy supply of diet B12. eating beef one or times in step with week is recommended.

Natural Sources of Folate


The egg is smaller in size but it is complete of potential materials which might be particularly required for the body. The egg is completely nutritious.
Do you recognize, one large egg carries almost 22 mcg of folate or about 6%. So it is advocated to take at the least 1 week a large egg each day will degree up the folate deficiency.
The large Eggs is likewise full of protein, selenium, riboflavin. Nutrition B12, Zexanthine, and Lutein. Zexanthine and Lutein work as antioxidant. Those help to reduce eye problems.                                                                                                                                                    The Eggs is also filled with protein, selenium, riboflavin. Vitamin B12, Zexanthine, and Lutein. Zexanthine and Lutein work as an anti-oxidant. These help to reduce eye disorders.

  • Banana

One Banana usually incorporates 24mcg of folate.

  • Papaya

Papaya is rich in an antioxidant and folate.

Sign And Symptoms Of Megaloblastic Anemia

There is a natural medical problem that any one of the vitamin deficiency disorders denotes itself in the first stages but when the deficiency provokes the threshold then it appears itself. So the reason that’s we must take a proper diet plan. Ingesting less isn’t always dangerous but ingesting with don’t care is harmful.

  • Tingling within the foot.
  • Wight lose
  • Dizziness
  • Muscle weakness
  • Mental confusion
  • Loss of appetite
  • Fast heart rate

How to diagnose the megaloblastic anemia

Usually, the CBC (complete blood count) test is used to diagnose the vitamin deficiency. In CBC the lab technologist finds the red blood cells count, amount of vitamin B9 and B12 in the blood, and the presence of intrinsic factors.

Treatment of Megaloblastic Anemia

The treatments rely upon the cause. If the cause is Vitamin B12 so vitamin B12 is recommended whoever has a deficiency of vitamin B9 have to start the folate products and dietary supplements.

 Vitamins B12 deficiency.

If the reason is vitamin B12, the remedy goal is to restore the balance.

The injection is generally favored while there may be severe malabsorption has been going on. The doctor additionally prescribes the tablets which must be taken after meal every day.

In the vegetable form, we had already discussed above the rich sources of Vitamin B12.

  •  Vitamin B9 deficiency.

If the cause is vitamin B9, both supplements and in foods form is recommended.  We had already the rich sources of folate above

 Vitamin b9 is available in both forms such as oral and injection.
