Monitoring hemoglobin levels is essential during pregnancy, particularly during the third trimester. Maintaining healthy hemoglobin levels is crucial to supporting your baby’s development and your own health as your body adapts to the growing baby.
Both the need for sufficient hemoglobin levels and the demand for oxygen rise during the third trimester of pregnancy. To avoid issues like anemia, the protein called hemoglobin, which carries oxygen in red blood cells, must be at the proper levels. Together with your healthcare provider, you can make sure that the last stages of your pregnancy go smoothly and healthily by knowing what’s normal and what might need attention.
Let’s look at what the optimal hemoglobin levels should be at this point and how you can keep or raise them. During this crucial period, knowing this information will help you stay aware and take proactive steps for your health and wellbeing.
| Hemoglobin Level | Importance |
| 11.0 – 14.0 g/dL | Normal range for pregnant women in the 3rd trimester. Ensures enough oxygen is carried to both mother and baby. |
| Below 11.0 g/dL | May indicate anemia, which can lead to fatigue and complications. It"s important to consult a healthcare provider. |
| Above 14.0 g/dL | Generally not a concern but should be monitored to ensure it’s not due to other health issues. |

Why is it determined?
All the soluble substances required for the baby’s complete development are given to it through the bloodstream prior to birth. One type of carrier of them is hemoglobin.
Heme iron and protein molecules form the basis of its structure. This combination enables you to give the baby’s body all the substances it needs.
The baby has grown significantly by the third trimester of pregnancy and occupies a large amount of the mother’s stomach. Its organ systems are all still evolving and differentiating. This ultimately results in a marked increase in the need for nutrients.
A decrease in this protein substance in the blood is not at all a consequence of some pathology. After the birth of the baby, the hemoglobin level gradually normalizes. By the beginning of the 3rd trimester, there is a physiological "thinning" of the blood. This is invented by nature so that nutrients can more easily penetrate to the developing baby. Doctors prescribe a general blood test to all pregnant women in the final period of pregnancy. With the help of this test, you can determine the number of red blood cells and hemoglobin. A decrease in these indicators is a sign of an anemic condition. Such pathology is unfavorable for both the mother and her baby.
Norms
Normal blood levels of this substance in the population range from 120 to 140 g/liter. They undergo substantial changes during pregnancy. This characteristic is mostly caused by the baby’s body receiving all the nutrients it requires for nine months from the mother’s blood flow, in addition to the mother’s own needs. The reference values of hemoglobin in the blood vary slightly between weeks of pregnancy. Doctors use a special table to quickly identify symptoms of various disorders. It is displayed as follows:
| Week of bearing a baby | 30 | 35 | 37 | 38 |
| Minimum acceptable hemoglobin levels (g / liter) | 110 | 111-112 | 113 | 118 |
It is evident from analyzing the provided values that a decrease of less than 110 g/liter is already undesirable. It’s crucial to remember that not all expectant mothers experience hemoglobin changes. It might get worse in the third trimester for some women. It is vital to make sure that its values \u200b\u200bdo not surpass the highest allowable values in such a circumstance.
What do changes indicate??
Variations in blood haemoglobin concentration are common during the third trimester of pregnancy. Its level rises or falls for a variety of reasons.
Increase in concentration in the blood
It is recommended that the blood’s hemoglobin level not surpass 140 g/liter by the third trimester of pregnancy. If this indicator shifts, it might be a sign that the expectant mother has any internal organ diseases.
Such a state is frequently brought on by a number of gastrointestinal disorders, a B vitamin deficiency, and some serious cardiovascular illnesses.
It is highly unfavorable to exceed this indicator over the average. Increased thrombus formation may result from it. It is very dangerous when tiny blood clots form in the uteroplacental blood flow system. They may obstruct a blood vessel’s lumen, resulting in nutritional abnormalities in the developing foetus. Should this pathology persist for an extended period, it will play a role in the development of the infant’s hypoxic state. This condition can be very unfavorable prior to childbirth. Premature birth is associated with multiple risks. Doctors will even prescribe cesarean sections in certain situations.
Decrease in blood concentration
The amount of hemoglobin in the blood usually decreases with the length of pregnancy. This indicator does not gradually increase until the very last weeks of the fetus’s intrauterine development. The concentration of this substance in the blood is greatly decreased in expectant mothers who are carrying multiple babies at once. Also, carrying a very large baby can cause a significant decrease in hemoglobin. Vegetarian women are particularly vulnerable to developing a blood shortage of this substance. An anemic state gradually takes hold when the diet becomes deficient in heme iron.
It might not show up very much in the early months of giving birth. The disorders start to worsen by the third trimester. Prior to childbirth, mandatory monitoring of this clinical indicator is necessary if the hemoglobin level is already 105–109 g/liter. Doctors will undoubtedly advise the expectant mother to closely monitor her diet in this situation. Adding more foods high in iron to your diet is often all that is needed to normalize this indicator.
Sometimes, a woman’s hemoglobin level can drop to 99–100 g/liter when she is carrying multiple babies at once. In such a case, close observation of the pregnancy’s progress is necessary, along with adherence to the doctor’s recommendations for raising the blood’s hemoglobin level.
The pregnant woman might not experience any anemia at all. Women typically "write off" all negative symptoms they experience to exhaustion and a protracted pregnancy.
A mild anemic condition may be present if the expectant mother starts to feel fatigued easily, even in the absence of physical activity, or if she feels the need to sleep during the day all the time. In certain instances, women experience these adverse symptoms as soon as the indicator falls to 100–104 g/liter.
An anemic condition can be suspected, but for its verification mandatory analysis is required. You can donate blood at any medical institution – both in a regular clinic and in a private laboratory. The test result is ready, as a rule, in a couple of hours. After the laboratory test, you should definitely consult a doctor. With a more pronounced anemic condition, the expectant mother may begin to have severe attacks of dizziness. In some cases, she may even lose consciousness. In order to avoid this, the doctor will suggest that the woman be hospitalized. During her hospital stay, the expectant mother will undergo intensive treatment, which will help normalize the hemoglobin level in her body.
It becomes more crucial to maintain healthy hemoglobin levels as the pregnancy enters the third trimester. Because it transports oxygen to the mother and the developing child, hemoglobin is essential. In this stage, hemoglobin levels between 11 and 12 g/dL are generally regarded as normal. Should the values drop below this range, anemia may be present, necessitating medical intervention.
Expectant mothers should undergo routine check-ups to monitor their hemoglobin levels. A medical professional can provide advice and recommend suitable treatments or dietary changes if there are any concerns. During this critical time, maintaining a balanced diet high in iron, vitamin B12, and folic acid can support healthy hemoglobin levels and general well-being.
Monitoring these levels and taking quick action to resolve any problems can help to ensure a healthier pregnancy and better outcomes for the mother and the unborn child. As the pregnancy goes on, managing and maintaining optimal hemoglobin levels is greatly aided by routine consultations with medical professionals.
Maintaining appropriate hemoglobin levels during the third trimester of pregnancy is essential for the health of the mother and the unborn child. Hemoglobin levels in pregnant women should ideally range from 11.5 to 14.0 grams per deciliter. This range lowers the risk of complications like anemia and helps guarantee that the baby gets enough oxygen for development. A balanced diet high in iron can help maintain these levels in check, as can routine check-ups.
