Five health conditions mothers can develop after giving birth

During pregnancy, a mother’s body undergoes vast structural and functional changes. But what many might not know is that the after-effects of these changes can last long after giving birth – and can even result in the development of new health conditions.

Here are just a few of the common conditions a mother can develop after giving birth:

1. Gallstones

One common condition that arises after pregnancy is gallstones. Approximately 12% of women are affected.

Gallstones are hard deposits commonly made of cholesterol that form in the gallbladder (an organ that releases bile to help the body digest fats). If these stones leave the gallbladder and become stuck in the ducts connecting the gallbladder and intestines, they can cause intense, sharp pain under the ribs (usually on the right-hand side) which may radiate into the back and shoulder. Gallstones can also cause vomiting and darkened urine.

During pregnancy, a mother’s gastrointestinal system slows down so that as many nutrients as possible can be delivered to the developing baby.

This gastrointestinal slowdown also slows bile leaving the gallbladder. Combined with the increase in cholesterol that happens in order to support foetal tissue development, this creates the perfect environment for gallstones to form.

But after giving birth, digestive motility increases again. This can sometimes force any stones that have formed to be flushed out the gallbladder.

Stones may need to be dissolved or the gallbladder removed in cases of severe symptoms.

2. Vision changes

The eyes can also be affected after pregnancy. The most common issues are blurry vision and dry eyes. These problems are caused by hormonal changes in the immediate period after delivery – namely the sharp drop in the hormones oestrogen and progesterone.

During pregnancy, changing oestrogen and progesterone levels cause fluid retention. This causes many tissues to swell – including the eyes. It also causes the eyes to gradually change shape.

But when hormones levels return to normal after pregnancy, any visual changes that have occurred can become more noticeable. Usually, these self-resolve – though for some the vision changes can remain as near- and far-sightedness.

In very rare cases, sight loss can even occur post-pregnancy – something which recently happened to one British mum. This was probably caused by optic neuritis, a condition where the protective layer of the optic nerve is attacked by the body’s own immune system.

During pregnancy, the maternal immune system is modified so it doesn’t attack and reject the foetus. But once the baby is born, mum’s immune system goes back to its pre-pregnancy state. In some, this results in the immune system over-reacting and attacking its own tissues.

Optic neuritis can be treated using corticosteroids which can restore vision. But in this mum’s recent case, these didn’t work.

She ended up having a plasma exchange – a procedure where the body’s plasma (the blood’s liquid component which carries hormones, nutrients and blood cells) is removed and replaced with donor plasma. Once she recieved the new plasma, her vision was mostly restored.

3. Postpartum thyroiditis

Another condition affecting around 10% of postpartum mums is postpartum thyroiditis. In mums with diabetes, as many as 20% may be affected.

This condition affects the thyroid. This gland produces hormones that help control metabolism, growth, energy levels and development. The thyroid is affected by the immune system’s postpartum rebound.

Postpartum thyroiditis first causes the thyroid to become overactive (hyperthyroidism), leading to weight loss, anxiety, heat intolerance and tremors due to the thyroid hormones’ overstimulating effect on the nervous system.

This is then followed by underactivity (hypothyroidism) where mothers feel cold, low mood and tiredness.

The reason the thyroid is initially overactive is because it releases the hormonal stores it has built up. Once these stores are depleted, it’s function is reduced.

Both conditions can be treated with prescription drugs. Many mums can stop taking these after a few months, once inflammation in the thyroid has decreased.

4. Postpartum pre-eclampsia

One of the more life-threatening post-pregnancy conditions is postpartum pre-eclampsia. This condition can affect as many as 27% of mums and is characterised by high blood pressure after birth. It can happen anytime from hours after birth to six weeks after delivery.

For many, symptoms are mild and may even be unnoticed. But it can also present as severe headaches, shortness of breath, abdominal pain and vision changes, which represent the more severe symptoms.

The condition can happen both in mums who had pre-eclampsia during pregnancy and those that didn’t. If left untreated, it can lead to brain damage, stroke or even death.

Postpartum pre-eclampsia can be effectively managed with antihypertensive medications, which lower your blood pressure.

5. Blood clots

Pulmonary embolism (a blood clot in a major artery in the lungs) is a rare but dangerous postpartum condition. It’s one of the leading overall causes of maternal death and has a sixty-fold increase in risk compared to non-pregnant women.

This condition tends to present up to six weeks after birth. It causes shortness of breath, heart palpitations and potentially coughing up blood.

During and after pregnancy, a mother’s body is in a “hyperclotting” state to reduce blood loss after delivery. This hyperclotting state can subsequently cause blood clots to form elsewhere in the body, such as veins in the legs. These clots can become dislodged, travelling to the major arteries in the lungs and blocking them.

Clotting risk can be managed with various therapies, such as with injectable anti-coagulant drugs.

Pregnancy makes large-scale changes to a mother’s body. But as soon as the baby is delivered, these changes usually reverse back to baseline – often quicker than they happened during pregnancy. This sometimes means the body fails to adapt, leading to various health conditions.

If you’re a mother who has recently given birth and feel something isn’t right, it’s best to see your GP.
