Pregnancy brings several physical and emotional transformations, and there could not be a more critical period than this when nutrition is concerned for both the mother and baby. The essential mineral iron performs many functions in the pregnant woman, including the facilitation of the increased volume of blood in the mother and baby, together with fatal development and well-being.
The most common disorder encountered by pregnant women is probably iron deficiency, and if left untreated, this often has grave consequences.
This article will discuss the causes, risks, symptoms, management, and the importance of maintaining optimal levels of iron for healthy pregnancy and delivery.
1. How Does the Iron Works in Pregnancy and Why it is Important?
Iron is one of the very important minerals. It performs several very vital roles in the body. Most importantly, it is used as a constituent part of haemoglobin, a red blood cell protein that carries oxygen from the lungs to all parts of the body. The demand for iron increases many times during pregnancy because:
- Increased blood volume: In pregnancy, the quantity of blood in a pregnant woman increases by about 50% to support the growth of the baby. More blood needs more haemoglobin, which again means an increased iron requirement.
- Fatal development: The baby also needs iron in order to develop, particularly for its red blood cells, brain development, and so many other important functions.
- Placental function: The placenta, the body that feeds the foetus, needs enough oxygen supply to serve efficiently, provided via circulation of maternal blood.
- Prevention of complications: It prevents anaemia or insufficient quantity of healthy red blood cells, which in turn may trigger complications during childbirth, fatigue and weakness.
With increased demands on the body of a pregnant woman, iron deficiency is likely to be experienced if intake is not kept at levels that will be able to meet these needs.
2. Why Is There Iron Deficiency in Pregnancy?
Iron deficiency in pregnancy occurs because there is simply not enough iron in the body to deal with the increase in demand. In many ways, this deficiency can arise from the following factors:
a. Increased Iron Requirements
During pregnancy, a woman's body requires nearly twice as much iron as usual to support the growth of the fetus and increase blood volume. If this demand is not satisfied through the diet, a deficiency develops.
b. Deficiency Due to Intake of Inadequate Amount of Dietary Iron
Many women are not consuming enough iron-rich foods in their diet, especially during pregnancy. There are two types of iron: the one found in plant-based products, known as non-heme iron, and the other from animal products or heme iron. While nonheme iron is omnipresent in plant sources, beans, lentils, and spinach, for example, it is much less bioavailable than its counterpart, heme iron in animal products, red meat, poultry, and fish.
c. Blood Loss
Some women experience antepartum haemorrhage, which occurs from minor bleeding, heavy periods before pregnancy, or due to medical conditions such as placenta previa or placental abruption. Blood loss can drain the body's iron supplies and potentially lead to deficiencies.
d. Multiple Pregnancies
Women who have had multiple pregnancies closely spaced likely also have iron stores depleted from previous pregnancies. Every pregnancy significantly increases the body's need for iron, and unless there is sufficient time to replace the depleted iron stores, it increases iron deficiency.
e. Gastrointestinal Disorders
Some gastrointestinal diseases, celiac disease or inflammatory bowel disease, can sometimes impair a body's ability to take in iron. On the other hand, morning sickness can minimize the amount of iron during intake and absorption, especially during the initial stages of pregnancy.
f. Low Preconception Iron Stores
Iron stores might be depleted even before women get pregnant. This occurs due to poor diets, heavy cycles, or some disorders which may be not well diagnosed and cause this situation. In that instance, it would be easy to establish that women whose iron stores were low before the onset of pregnancy are likely to undergo iron deficiency as they progress through their pregnancy.
3. Risks and Complications of Iron Deficiency during Pregnancy
An iron deficiency would contribute to more severe ones, including iron-deficiency anaemia, which is correlated with many risks and complications for the pregnant woman as well as to the fetus developing inside her. The risks involve the mother and the baby alike.
a. Risks to the Mother
- Fatigue and weakness: Iron deficiency would cause extreme fatigue, making it hard for the pregnant woman to maintain her normal activities and the potential of accidents or falling.
- Poor immune strength: An iron deficiency weakens the immune system. Thus, pregnant women are more susceptible to infections.
- Higher chances of premature labour: Studies have shown that many women who experience preterm labour are those with iron-deficiency anaemia. Preterm labour poses a risk to the baby's possible complications as well.
- Risk factor for postnatal depression: Research has shown that there is a connection between iron deficiency and the onset of postnatal depression. Iron is essential for brain function; when there is a low level of iron in the blood, there may be a transformation in mood during puerperium.
- Hypertensive complications during delivery: In extreme cases, anaemia can cause hypertensive complications with life-threatening consequences in women at the time of delivery. This causes postpartum haemorrhage because of excessive blood loss.
b. Fetomaternal Risks
- Low birth weight: Infants born to mothers suffering from iron deficiency anaemia are likely to be underweight at birth and develop delayed health and developmental functions
- Delayed cognitive and behavioural development: Iron is essential for the development of the human brain. Infants born to mothers suffering from iron deficiency anaemia are more prone to delayed cognitive development and learning problems.
- Risk of stillbirth or neonatal death: Severe iron deficiency anaemia in pregnancy has been shown to increase the risk of stillbirth and neonatal death.
- New-born iron deficiency: Infants at birth acquire their irons during pregnancy from their mothers. A deficiency in their mothers places them at risk of developing iron deficiency and anaemia in infancy.
4. Signs of Iron Deficiency During Pregnancy
The best option to not suffer through complications is early detection of signs of Pregnancy. However, we can check the iron deficiency with the iron deficiency kit the case may be confusing with common complications experienced in pregnancy. Thus, identifying them right might be a challenge. Here are some common signs that are seen among pregnant women due to iron deficiency:
- Fatigue and weakness: Feeling unusually tired and weak even after rest may become one of the signs of low iron levels.
- Pale skin: The skin may be pale or sallow because of little or no haemoglobin.
- Shortness of breath: Even the most mundane acts of feeding or performing daily chores become difficult as well as challenging to breathe in time during activities.
- Dizziness or light-headedness: Patients with iron deficiency often complain of fainting spells or dizziness.
- Rapid heart rate: There may be palpitations or a fast and abnormal heart rate, as the heart needs more effort to pump oxygen around the body.
- Headaches: When a woman has a deficiency in iron levels, they are bound to feel headache symptoms because of poor delivery of oxygen to the brain.
- Cold hands and feet: A woman is also said to have cold hands and feet when their blood circulates poorly due to iron deficiency.
- Cravings for non-food items (pica): Some pregnant women will develop a condition known as pica, where some women will experience cravings for non-food substances such as ice, dirt, or chalk.
Iron deficiency can be diagnosed using a simple blood test, by measuring the level of haemoglobin and ferritin, a protein which acts as the body's iron store. Pregnant women should be screened for anaemia at their first prenatal visit and also in later pregnancy, although this will depend on individual risk factors. If iron deficiency or anaemia is detected, further testing may confirm the cause and extent of it.
5. Management of Iron Deficiency in Pregnancy
Fortunately, iron deficiency may be dealt with very effectively by dietary modification, supplementation, and follow-up. Early treatment of iron deficiency will prevent further complications during pregnancy and ensure a problem-free pregnancy.
a. Dietary Modification
Diet is one of the best ways through which iron deficiency may be prevented and managed during pregnancy. Pregnant women are supposed to take iron-rich foods on a daily basis. There exist two types of dietary iron, which are heme and non-heme iron.
- Heme iron: Heme iron comes from red meat, poultry, fish, and liver. It is easily absorbed in the body compared to non-heme iron.
- Non-heme iron: That is iron obtained from a plant-based food and a less readily absorbed type but still useful. Beans, lentils, spinach, tofu, fortified cereals, and nuts are the sources for this one.
To enhance the utilization of non-heme iron by the body, it should be taken with vitamin C-rich food, such as citrus fruits, tomatoes, and bell peppers. Conversely, foods or supplements containing calcium, coffee, and tea must be avoided with meals that contain iron since they inhibit the absorption of iron by the body.
b. Iron Supplements
Most pregnant women will have to take iron supplements because their iron levels will be raised sometimes, and if they get diagnosed with iron deficiency or anaemia, such supplement intakes will be recommended. Most prenatal vitamins already contain a minimal amount of iron, while a shortage may prompt the healthcare provider to prescribe supplements that have large amounts of iron.
Iron supplements are usually furnished as ferrous sulphate, ferrous gluconate, or ferrous fumarate. Some women taking iron supplements may also experience constipation, nausea, or stomach upset due to side effects. In these situations, a healthcare provider could advise decreasing the dose or switching to a different form of iron.
This involves adhering to the prescribed dosage and, if necessary, taking iron supplements as directed. Too much iron can be toxic, thus consultation with a healthcare provider prior to initiation of any supplement is wise.
c. Follow-up
After iron deficiency diagnosis treatment, follow-up monitoring of iron levels happens regularly. Blood tests may need to be repeated during pregnancy to ensure that an increase in the level of iron develops and that treatment is helpful.
d. Managing Underlying Causes
If the cause of iron deficiency is some underlying disease, such as gastrointestinal problems or heavy bleeding, managing the underlying cause helps prevent the recurrence of the deficiency. This might be treatments, changes in diet, and more.
6. Prevention of Iron Deficiency in Pregnancy
The best time to treat iron deficiency is before it happens. Here are the key strategies for prevention of iron deficiency during pregnancy:
- You need to have an iron-rich diet: Ideally, you should include both home and non-home iron sources. Coincide iron-rich food intake with vitamin C to enhance absorption.
- Take prenatal vitamins if you are pregnant: Ensure that your prenatal vitamin contains enough iron. Discuss this with your healthcare provider for further supplementation needs.
- Keep track of your iron level: Visit a prenatal clinic for follow-up check-ups as your doctor will advise you on when to take blood tests or use an iron deficiency kit to ensure that your iron level is adequate.
- Limit blood loss: The flow of blood is usually immense when there is blood loss during pregnancy. In most cases, you are taken to a medical facility to ensure that the condition is managed to avoid bringing about iron depletion.
Conclusion: Iron in a Healthy Pregnancy
Iron deficiency during pregnancy is one common condition that is utterly preventable but has a very adverse outcome for the mother as well as the baby. Understanding the causes, risks, and symptoms of iron deficiency is a great benefit for pregnant women to take proactive steps to maintain adequate iron level levels throughout pregnancy. Dietary changes and supplementation or check-ups may bring a healthier pregnancy, safer delivery, and a healthier beginning for the baby.
If you are pregnant, or if you plan to conceive and bear a child, it would thus be advisable to visit your healthcare provider about your iron needs as well as how to prevent or manage the possible emergence of iron deficiency. Keep yourself and your baby healthy for a smooth delivery.
