Anaemia in pregnant women isn’t uncommon. A mild condition of anaemia is no cause for anxiety and is easily treatable when detected at an early stage. However, if left untreated, it may prove dangerous for both, the mother and baby.
What is Anaemia?
The medical condition when the total amount of red blood cells or haemoglobin decreases in the body is called anaemia. As a result, in pregnant women, the body doesn’t have enough red blood cells to carry the required oxygen to the tissues and the foetus.
Besides other nutrients, an expectant mother requires a diet rich in iron, folate and Vitamin B12 to produce more blood for the growth and nourishment of the baby. When this dietary requirement isn’t met, you may become anaemic.
Normally, an average woman carries about 5 litres of blood in her body. During pregnancy, to meet the need of the growing foetus, this amount escalates to 7-8 litres of blood at the end of the third trimester.
Pregnant women are more susceptible to anaemia because the body produces more blood than usual. This requires extra iron, folate and Vitamin B12 to produce substantial amounts of healthy red blood cells and haemoglobin. If you don’t take care of your diet, you might end up with a deficiency.
Types of Anaemia in Pregnancy
Did you know that there are more than 400 types of anaemia? Some of these are prevalent during pregnancy. The most common types of anaemia found in pregnant women are:
Haemoglobin is a protein in the red blood cells that carries oxygen from the lungs to the rest of the body. Iron-deficiency anaemia is the condition where the body doesn’t have enough iron to produce the required amounts of haemoglobin. Symptoms of iron deficiency in pregnancy are quite common among expectant mothers.
Due to the deficiency of iron, the blood does not carry the required amount of oxygen to the various parts of the body. This affects both the mother as well as the foetus.
Folate is a type of Vitamin B that the body requires to produce new cells. It also helps in forming healthy red blood cells. During pregnancy, the daily requirement for folate increases. Folate-deficiency causes a decline in the amount of healthy red blood cells.
Folate-deficiency anaemia can lead to serious birth defects such as neural tube abnormalities (spina bifida) and low birth weight.
Vitamin B12 Deficiency Anaemia:
Cobalamin, or, Vitamin B12 is vital for the production of red blood cells. Women who do not include milk and other dairy products, eggs, poultry, meat in their diet suffer from Vitamin-B12 deficiency anaemia. In this condition, the production of the required amount of red blood cells is impaired.
Sometimes, an expectant mother may be consuming the required Vitamin B12, but the body may be unable to process the vitamin. This may also lead to the mother-to-be developing anaemia.
Vitamin B12 deficiency is known to cause pre-term labour or severe birth defects such as neural tubal abnormalities.
Symptoms of Anaemia While Pregnant
In mild cases of anaemia, one may not show any symptoms. However, as it grows severe, the followings symptoms may develop:
- Fatigue and weakness
- Shortness of breath
- Pale complexion
- Rapid or irregular heartbeat
- Chest pain
- Cold hands and feet
- Trouble concentrating or irritation
Initially, the symptoms of anaemia during pregnancy may be mild; however, there is a risk of ignoring them. With time, the symptoms may worsen and will have to be treated so as to not lead to complications later. You must immediately consult a doctor if you experience any of these symptoms.
These symptoms generally are controlled with dietary supplements like iron tablets, folic acid and Vitamin B12 supplements.
Remember, some amount of fatigue and weakness is unavoidable, and also normal due to the growing foetus in the body. Do not panic. The doctor will guide you best.
What Causes Anaemia During Pregnancy?
There are a number of factors that can cause anaemia in pregnant women. The risk is higher when:
- the woman is pregnant with more than one baby
- the pregnant woman vomits excessively due to morning sickness
- the woman has been anaemic even before conceiving
- the expectant mother doesn’t eat a diet rich in iron, folate and Vitamin B12
- there are two pregnancies close together
- a teenager becomes pregnant
Risks of Anaemia
Deficiency of iron, folate or Vitamin B12 may lead to complications of anaemia in pregnancy. It may have adverse effects on baby and mother.
Untreated iron-deficiency may cause:
- Preterm or low birth weight baby
- Post-partum depression
- Developmental delays in the child
- An anaemic baby
Undetected and untreated folate or Vitamin B12 deficiency may cause:
- A preterm or low birth-weight baby
- Neural tube defects or birth defects in the brain or spine
How to Diagnose Pregnancy Anaemia?
During the course of pregnancy, your doctor will periodically monitor you for chances of anaemia. Blood tests are conducted not only during the first trimester, but also in the second and the third. This is done to rule out the possibility of anaemia in the later stages of pregnancy too. The following blood tests are carried out to diagnose anaemia:
- Haemoglobin Test: This test is carried out to measure the amount of haemoglobin in the body.
- Hematocrit Test: The purpose of this test is to measure the percentage of red blood cells in the blood.
How is Anaemia Treated in Pregnant Women?
Your doctor may prescribe the following supplements to treat anaemia during pregnancy.
- Iron and Folic Acid: This is to ensure that required amount of iron and folate is maintained in the body. You may be advised to increase the intake of iron and folate-rich foods.
- Vitamin B12: You may also be recommended Vitamin B12 supplements in addition to foods like meat, dairy products and eggs to help tackle Vitamin B12 deficiency.
How Can Anaemia Be Avoided?
Prevention of anaemia in pregnancy must be of utmost importance for all expectant mothers. You must eat healthily and ensure to include iron-rich foods such as:
- Dark green, leafy vegetables like spinach, kale and broccoli
- Beans, lentils, tofu
- Lean red meat, poultry
- Nuts and seeds
- Cereals and grains
Remember that Vitamin C helps the body to absorb iron better. So, whenever you are looking to eat iron-rich food, also include foods like citrus fruits, tomatoes, kiwi, strawberries and bell peppers which are rich in Vitamin C.
When to Call Your Doctor?
All expectant mothers should consciously avoid any deficiency in the body during the course of the pregnancy. Moreover, anaemia during pregnancy third trimester should strictly not be ignored. Consult your doctor if the symptoms of anaemia persist for a long time. It must be immediately treated in order to avoid any complications.
While untreated anaemia can prove to be harmful, deficiency of iron, folate and Vitamin B12 can be controlled with the right dietary intake and supplements. Treating such deficiency early on can save the mother and baby a great deal of trouble. The key is to regularly consult your doctor for periodic checkups.
