5 DANGERS OF SMOKING DURING PREGNANCY

Affinity Health, a leading provider of high-quality healthcare, explores the dangers of smoking during pregnancy.

“While the prevalence of smoking during pregnancy in South Africa has decreased in recent decades, it is still a significant public health concern that requires continued attention and support to help pregnant women quit smoking and protect the health of their unborn babies,” says Murray Hewlett, CEO of Affinity Health.

“Quitting smoking is the best way to protect the health of both the mother and the baby. Many resources are available to help pregnant women quit smoking, including counselling, support groups, and nicotine replacement therapy. Seeking help is crucial for a healthy pregnancy and a healthy baby.”

When a woman smokes cigarettes during pregnancy, the harmful chemicals in the tobacco smoke enter her bloodstream and pass through the placenta to the developing foetus. This can lead to a range of adverse health effects.

Despite this, many women smoke during pregnancy because they are unaware of the risks or find quitting difficult.

Dangerous Chemicals in Cigarettes

Cigarette smoke contains various harmful chemicals that can affect foetal development and increase the likelihood of a range of health problems in the short and long term.

A few of the many chemicals found in cigarettes include:

  •  Nicotine is the addictive substance in cigarettes, and it increases the risk of heart disease, stroke, and lung cancer.
  •  Tar, a sticky brown substance, is deposited in the lungs when inhaled cigarette smoke can lead to chronic obstructive pulmonary disease (COPD).
  •  Carbon monoxide, a poisonous gas, reduces the amount of oxygen in the bloodstream and can cause shortness of breath, dizziness, and headaches.
  •  Benzene, a carcinogen, can damage the bone marrow and lead to leukaemia.
  •  Formaldehyde, used to preserve dead bodies, is also found in cigarettes and is a known carcinogen.
  •  Acrolein, a toxic liquid, irritates the eyes, nose, and throat and can cause lung damage.

Smoking During Pregnancy: The Top Risks to Your Unborn Baby’s Health

Affinity Health lists five of the most significant risks associated with smoking.

1. Low Birth Weight

Smoking during pregnancy is one of the leading causes of low birth weight. Babies born with low birth weight are at higher risk of health problems, including respiratory distress, feeding difficulties, and infections.

They may also experience developmental delays and have a higher likelihood of long-term health problems, including chronic diseases such as diabetes and hypertension.

According to the American Pregnancy Association, smoking during pregnancy can result in an average 180 grams decrease in birth weight. This risk increases with the number of cigarettes a mother smokes per day.

2. Premature Birth

Smoking during pregnancy is also a significant risk factor for premature birth (defined as giving birth before 37 weeks of gestation).

Premature babies are at higher risk of developing health problems, including respiratory distress syndrome, cerebral palsy, and vision and hearing problems.

According to the Centre for Disease Control and Prevention (CDC), smoking during pregnancy raises the chance of premature birth by 25%.

3. Stillbirth

Smoking during pregnancy can also lead to stillbirth (when a baby dies in the womb after 20 weeks of pregnancy). Stillbirth is a devastating loss for families and can be caused by various factors, including smoking during pregnancy.

According to the Royal College of Obstetricians and Gynaecologists, smoking during pregnancy raises the chance of stillbirth by up to 40%.

4. Sudden Infant Death Syndrome (SIDS)

Sudden Infant Death Syndrome (SIDS) is the unexpected death of an infant under the age of one year, typically while sleeping.

Smoking during pregnancy is a risk factor for SIDS, and babies born to smokers are up to three times more likely to die from SIDS than babies born to non-smokers.

Smoking during pregnancy raises the risk of SIDS by altering the baby’s respiratory and immunological systems, leaving them more vulnerable to illnesses.

5. Developmental Delays and Long-Term Health Problems

Smoking during pregnancy can also lead to developmental delays and long-term health problems for the baby.

Children born to moms who smoked during their pregnancy had an increased risk of developmental impairments, including language and cognitive development delays.

Smoking during pregnancy can also affect the baby’s DNA, leading to long-lasting changes that may increase cancer risk and other chronic diseases later in life.

What is HELLP?

Pregnancy and the arrival of a new baby is a time of great excitement and joy for expectant parents.  However, occasionally there can be complications, which is why pregnant moms should have regular health checks and be aware of any unusual symptoms that may develop.

Over the past few years, there has been discussion around a condition known as HELLP Syndrome. It’s a life-threatening complication in pregnancy that can be difficult to diagnose. We reached out to Dr Morgan Mkhatshwa, Head of Operations at Bonitas Medical Fund and his clinical team, to get some answers and advice about HELLP.

What is HELLP Syndrome?

HELLP (Haemolysis, Elevated Liver enzymes, Low Platelet count) Syndrome usually develops before the 37th week of pregnancy but can occur shortly after delivery.  It’s a serious complication that affects the blood and liver.

H = Haemolysis is the breakdown of red blood cells that carry oxygen from lungs to the rest of the body.

EL= Elevated liver enzymes.  High levels of these chemicals in the blood can be a sign of liver problems.

LP = Low platelet count.  Platelets are little fragments of blood cells that help with blood clotting.  A low platelet count can lead to serious bleeding.

What causes HELLP?

‘We don’t know what causes HELLP syndrome,’ says Dr Mkhatshwa, ‘however, you are at risk if you have pre-eclampsia or eclampsia.’  About 1 to 2 in 10 pregnant women (10 to 20 percent) with pre-eclampsia or eclampsia develop HELLP. 

Pre-eclampsia is caused by high blood pressure. It usually starts after the 20th week of pregnancy or giving birth. Eclampsia is when pre-eclampsia is uncontrolled and causes seizures. Many women are diagnosed with pre-eclampsia before they have HELLP which is a more severe form of pre-eclampsia.

What are the symptoms / signs of HELLP

You may feel tired, have pain in the upper right part of the belly, bad headaches and nausea or vomiting. You may also experience swelling, especially of the face and hands and blurry vision. Some women develop HELLP suddenly, without having any signs or symptoms. 

If you have any signs of HELLP Syndrome, call your medical practitioner, emergency services or go to a hospital emergency room for medical care right away.

How is HELLP diagnosed?

To find out if you have HELLP Syndrome, your healthcare provider will do a physical exam to check  for:

  • Belly pain or soreness, especially in the upper right side
  • An enlarged liver
  • High blood pressure
  • Swelling in your legs

Other tests could include:

  • Blood tests to check your liver enzyme levels, lactate dehydrogenase and full blood and platelet count with a peripheral smear
  • Urinalysis to check for protein in the urine
  • A CT scan to see if there’s bleeding in your liver
  • Non-stress test or ultrasound to check your baby’s health. A non-stress test checks your baby’s heart rate, in the womb, to see how the heart rate changes when your baby moves. This test is to make sure your baby’s getting enough oxygen. Ultrasound uses sound waves and a computer screen to show a picture of your baby inside the womb

Is HELLP painful?

Symptoms of HELLP include serious pain just below the ribs, or the upper right side of the chest area (where the liver is), shoulder pain or pain when breathing.

How is HELLP treated?

You may be given medication to control your blood pressure and prevent seizures or you may require a blood transfusion to treat anaemia and low platelet levels. 

Early birth may be necessary because HELLP complications can get worse and harm both you and your baby – either through an induced labour or by C-Section depending on the health assessment results of the baby. 

How does it impact the baby?

Infants born to mothers with HELLP Syndrome may have a variety of birth injuries: Intrauterine growth restriction (IUGR) or severe respiratory distress.

Are there long term effects of HELLP?

A history of HELLP Syndrome means you are at increased risk for recurrent pre-eclampsia and HELLP Syndrome as well as increased long-term morbidities, particularly depression and chronic hypertension.

Can HELLP develop after childbirth?

Yes, up to 30% of all patients who develop HELLP Syndrome do so after giving birth, typically within 48 hours. 

Can I have another baby after HELLP syndrome?

If you had HELLP in a previous pregnancy, regardless of the time of onset, you have a greater risk for developing it in future pregnancies.

‘The condition is serious but rare’, stresses Dr Mkhatshwa. ‘Throughout your pregnancy it’s important to understand the changes your body is going through and to discuss any unusual pain or symptoms with your medical practitioner. This will ensure you receive the right help especially if you develop a complication and make the pregnancy and birth the joyous event it should be!’

Veganism and pregnancy

Veganism is becoming an increasingly popular lifestyle which abstains from the consumption and use of animal products, predominantly for health, and/or ethical reasons. If you’re vegan and are considering pregnancy, or are pregnant, you are probably wondering how to best provide nutrients for your growing baby, and if veganism is still the best option for both of you.

Can I stay vegan while pregnant?

Veganism is often criticised for its lack of certain vitamins and minerals that a typical ‘balanced’ diet contains. Luckily, it is still possible to stick to your vegan diet during pregnancy – you’ll just have to make sure that your growing baby receives the nutrients that she needs.

While pregnant, it’s important to eat foods that contain folic acid (a B vitamin), calcium, vitamin D, iron and protein – you can get this from the food you eat as well as supplements. If you’re wondering where you can find these important nutrients in a plant-based diet, read on.

Citrus fruits, dried beans and leafy green veggies are all foods that include folic acid. Typically dairy is a source of calcium, however, non dairy foods rich in calcium are broccoli and kale.  Vitamin D can be found in mushrooms and fortified products, such as rice milk and soy milk.  Although meat is often seen as a primary source of protein, beans, peas, nuts and seeds are all rich in protein. Potatoes and tofu are also good foods to eat when replacing meat protein, and iron can be found in spinach and beans.

What nutrients are typically lacking in a vegan diet?

As a vegan, there are certain nutrients that you can’t find in plants – during pregnancy it becomes even more important to supplement these. Vitamin B12 (which helps with proper brain development), vitamin D (which aids bone and teeth development), omega 3 fatty acids and iron (you’ll need about twice as much when pregnant) are vitamins and minerals you might need to supplement.

Even if you’re not vegan, making sure your baby gets all the correct nutrients is important and may mean adjusting your diet. If you are planning on sticking to a strict diet plan it’s a good idea to consult with someone knowledgeable first.

Should I be exercising while pregnant, and if so, how much?

For most exercise is a part of life, so it is natural to want to keep active for as long as possible while pregnant. You may wonder how much exercise you can keep doing as your baby develops, and what routine changes you’ll need to make as your baby grows bigger.

If you have a complicated pregnancy or are dealing with a weak cervix, a low placenta or suffering from a heart condition, diabetes or asthma, it is best to consult with a doctor or health professional before putting together a pregnancy exercise plan.

What are the benefits of exercise during pregnancy 

Improving overall health and wellness, exercise is a vital part of keeping you feeling your best and can help with backache caused by pregnancy, as well as prepare you for labour and delivery.

If you were active before your pregnancy, you should be able to keep training with modifications made to your program. Exercises that are low impact and carry small risk of injury are best and you should be able to remain active until birth.

Exercising during pregnancy can help boost your mood and energy levels, improve muscle tone, strength and lessen back pain. Exercise can also help reduce fatigue and stress, as well as help improve your sleep, all of which helps make your pregnancy easier on your body and mind.

Staying fit can also help shorten your post delivery recovery time, however, getting back into exercise postpartum can be difficult and you should avoid pushing yourself too hard in the beginning.

Exercising during pregnancy isn’t only good for your overall wellness, but studies show that it can also improve your baby’s health.

What type of exercise should I be doing? 

During pregnancy it is important to keep tabs on how your body is feeling. If you have been exercising frequently pre-pregnancy it should be fine to continue to do so in moderation, however, if something feels strange or uncomfortable it is best to consult a health practitioner.

Swimming, prenatal yoga and pilates, walking and water aerobics are all exercises that you can focus on during your pregnancy. Water activities are good as they give you buoyancy and put very little strain on your body, especially when you are close to giving birth.

If you were an avid runner before, you should be able to continue into pregnancy with some alterations to your program. 

Exercise to avoid

High impact sports with a risk of falling should be avoided. These include horse riding, mountain biking, downhill skiing. Contact sports, such as rugby, kickboxing and soccer are also preferable to avoid as there is a risk of being hit. Scuba diving is a big no-no as the baby has no protection against decompression sickness.
