Pregnancy is a time of joy but also one of anxiety, stress and fear. One of the dangerous things you could face during your pregnancy is the threat of blood clots. Even though pregnant women only face a risk of 1 in 1000 of developing a blood clot, it is a highly critical condition and can lead to serious complications for you and your unborn baby. The important thing to do is stay calm in the face of pressure to deal with the many problems of pregnancy. Fortunately, there are several things you can do to protect yourself and your child from the dangers posed by blood clots.
Your body can be injured in many ways. If your skin receives a cut, your body will send an army of special blood cells known as platelets to help. Platelets, along with an assortment of clotting factors, stick together to form a seal at the injury site, and stop blood from leaving the body. Clotting in such circumstances is an important bodily process to prevent blood loos. However, if a clot forms inside your veins and is unable to dissolve, this can become a dangerous situation.
Women face a much higher risk of developing a blood clot in the uterus during pregnancy than non-pregnant women. This is due to the raised oestrogen levels in their blood, which promote the activity of clotting factors. While the clot may not be dangerous in itself, depending on the location, it might cause severe complications. Blood clots can form at any time during the pregnancy or even for a few weeks after you give birth.
There are two main kinds of blood clots that form inside the body. They are:
Blood clots that form inside veins or arteries are known as a thrombus. Thrombus clots can also develop inside the heart. A thrombus is basically a coagulated mass of red blood cells, platelets and fibrin protein. It can block healthy blood vessels and prevent blood flow, leading to a condition known as thrombosis. Generally, thrombosis occurs in the leg veins, but sometimes can happen elsewhere in the body. Thrombosis in pregnancy is quite common and very dangerous. The two main kinds of thrombosis are:
An embolus is a clump of material that moves through the blood vessels. It is most commonly a thrombus that has dislodged from a blood vessel, but can occasionally be fat or air bubbles. An embolus during pregnancy can also obstruct the flow of blood in various organs in the body, giving rise to a condition known as Venous Thromboembolism. If it hampers blood flow to the heart, lungs, or brain, it could cause severe damage or even death.
There are several reasons for the formation of blood clots during your pregnancy. Some of them are:
Having cholesterol plaques clogging up your arteries will affect blood flow in that area, making you more susceptible to a thrombus.
Standing or sitting for long periods can promote the development of blood clots in the leg. Make sure you don’t sit cross-legged for too long either.
Blood clots can develop in pregnant women who do not stay hydrated by drinking water or juices. Hyperemesis gravidarum is a sickness that could cause dehydration as well.
If you have recently undergone invasive surgeries that involve cutting into arteries and veins, you face a higher risk of blood clots.
The increase in the size of your baby during pregnancy will start to put pressure on the veins that lead to the pelvic region. This makes it likelier for a clot to form in that region.
Some kinds of drugs, such as estrogen supplements or birth control tablets, can promote clotting.
Developing a blood clot is uncommon, but the further you progress in your pregnancy the higher is the risk, peaking at the first month after your child is born. There are many risks that can cause blood clots during pregnancy. They are:
Heredity is one of the common causes of pregnancy blood clots. If women in your family have this tendency, it is likely you will too.
Having illnesses like heart disease, sickle cell anaemia, thrombophilia, high blood pressure, diabetes or lupus greatly increases your risk of developing blood clots.
Being over 40 makes your blood more likely to clot, so pregnant women above the age of 35 should take extra care.
Smokers or second-hand smokers are at high risk of developing blood clots, as cigarette smoke tends to damage the inner lining of the blood vessels, as well as make platelets stickier.
Having a BMI higher than 30 during pregnancy can cause reduced blood flow in the body, enhancing the formation of clots.
Women who have been through fertility treatments can in rare cases develop this syndrome. Here, blood clots form as this condition results in injury to ovarian blood vessels.
As a pregnant woman, you are prone to constantly worrying for both your health and your baby’s. Instead of fretting about another possible danger, just take note of all the signs your body is trying to show you. If you find yourself facing any of the following symptoms, you could have a blood clot and need to go to the emergency room immediately.
There are several ways in which blood clots can be determined by your doctor. A few commonly used techniques are:
Thrombosis kills someone every five minutes. As the risks of blood clots during pregnancy are significantly increased, it could cause serious damage to both you and your unborn child. Some of the complications that can emerge in your body from developing pregnancy blood clots are:
When an embolus moves from its initial location, it is driven around by the bloodstream. If it somehow makes it to the lungs, it is known as a Pulmonary Embolism (PE). PE is a type of VTE along with DVT. This condition can drastically reduce oxygen levels, damaging multiple tissues and organs in the body. The symptoms of PE are shortness of breath, feeling faint, irregular heartbeat and anxiety.
Also known as a heart attack, it can occur if the blood clot obstructs the heart muscles from receiving the oxygen and nutrients it requires. This could lead to the slow death of the heart tissues, causing a heart attack. Heart attacks can cause severe damage to the heart and are often fatal.
The brain requires a constant supply of blood to function. Cerebral Vein Thrombosis can stop blood from reaching the brain, or in extreme cases, result in a bursting of the blood vessel. This is known as a stroke. Symptoms of a stroke are vision loss, dizziness, seizures, lack of feeling on one side of the body, and inability to move or speak. In many cases, strokes can lead to brain damage or fatality.
This is one of the most common conditions that some pregnant women go through, especially in their third trimester. Preeclampsia causes a rise in blood pressure, which affects the functions of the liver and kidneys. These organs may also be damaged if not treated in time. Some of the warnings signs of preeclampsia are headaches, protein in the urine, and unclear vision.
Blood clots are not only dangerous to your health, but they can also cause severe harm to your unborn child, especially if they travel to the uterus. Blood clots can occasionally form inside the placenta, which will result in a blockage in the foetus’s blood supply. A few of the dangers they can cause to your baby are:
As the placenta is the organ that serves as the oxygen and food highway between the foetus and the uterus, blood clots developing in the placenta will block the flow of blood to the foetus. This could put the life of your unborn child in serious jeopardy.
If the placenta is unable to function efficiently, oxygen and nutrients will not reach the foetus. This will result in the foetus developing incompletely or abnormally. It results in about 20% stillbirths, and the remaining 80% babies are likely to be underweight and might have developmental disabilities, obesity or diabetes in later life.
Blood clots may also lead to the foetus dying before the third trimester, while still in the uterus.
Blood clots can also lead to a premature birth, which means that the baby is born a week or more before its due date. These babies are underweight and might develop hearing conditions and vision problems, cerebral palsy, and lower IQ.
Deep Vein Thrombosis might be a debilitating condition, but you can still have a successful pregnancy even if you are at high risk. Reducing the risk of developing a clot until birth and for a few months afterwards is crucial. Some of the things you can do in your late pregnancy are:
If the doctor observes blood clots in your body during pregnancy, there are several ways with which she might treat them.
Heparins are a class of molecules that behave as anticoagulants. They prevent the formation of clots in the blood and thereby reduce the chances of getting deep vein thrombosis and pulmonary embolisms. This treatment will continue for at least 6 weeks after delivery.
It is an anticoagulant that is very efficient in treating DVT and PE, but is not recommended in pregnant women due to its side-effects, such as internal bleeding and tissue damage. A couple of weeks after you have given birth, your obstetrician will prescribe warfarin until all the blood clots have disappeared.
New research is showing the promise of a technique which involves surgically inserting a small device into the inferior vena cava of the heart to reduce the risk of pulmonary embolisms. However, it has been found to increase the occurrence of deep vein thrombosis.
Due to the critical nature of pregnancy blood clots, there are some things that you must compulsorily do to keep them away from you and your child.
This is the most important advice. In addition to advancing your cardiovascular health, getting physically active will keep your circulation in peak condition and not give your blood a chance to clot. Always ask your healthcare provider before you indulge in any kind of exercise while pregnant, especially if you are overweight. If you are medically advised to take bed rest during your pregnancy, anticoagulant medicines can keep the blood clots at bay.
Wearing compression clothing will prevent damage to your veins and improve blood flow. This will also lower the chances of DVT.
Even if you have an active lifestyle, try not to remain seated or lying down when you’re at home or at work. Stand up now and then, take a short walk around the house or the office before getting back to what you were doing. Keep your leg muscles relaxed by giving them regular massages. If you’re travelling, make sure you get up and move around the car, bus, train or plane at least every half an hour.
This is something crucial to our health, yet we still forget to do it enough. Most people need at least 2 litres of water a day. Pregnant women will do better drinking 3-4 litres every day.
Eating a balanced diet, that is lots of fruits, vegetables, lean meats, and whole grains, is important to stay healthy. Avoid smoking and alcohol as the former irritates the artery linings and the latter thins the blood.
Before you get overwhelmed by the amount of information you have just read, take a few minutes to relax and take a few deep breaths. Take everything one step at a time, and you will find yourself being able to handle the toughest of decisions. Now that you feel a little calmer, please understand that you have to face none of this alone; you have the support of your partner, family, friends and doctor to push through your difficult but rewarding time. Taking precautions against the dangers posed by blood clots is one of the most important things you can do to safeguard the health of your baby and yourself.
