The impact of pregnancy on the health of the bones is something that has been studied and observed for many decades. It has been shown that pregnancy can both be of detriment and of benefit to the bones. This is something that we are going to explore and explain today!


Pregnancy places several additional demands on the body, meaning that this can be a physically and emotionally demanding experiece. It is important therefore to take extra care to maintain optimum health during this time. This applies both to the attention you pay to your diet, as well as the amount of exercise and physical activity you are engaging in.


The majority of people are unlikely to experience any serious harm to the health of their bones during pregnancy, but it is something that can sometimes occur. Even though the chances of experiencing a problem may be low, it is still certainly worth paying extra attention to the health of the bones during pregnancy. This is not only for the benefit of the parent, but also for the baby.


Calcium in the Womb


Before babies are born they will require a great deal of calcium as they grow in the womb. This is essential for the development of the skeleton and is especially important in the final three months before birth.


Pregnancy Calcium Health


If the baby is not receiving enough calcium in the womb then this mineral will be supplied from the bones of the parent. This is not ideal because this is then depleting the calcium reserves from the pregnant parent. However, the body is able to deal with this in a combination of ways!


First of all, it has been observed that pregnant people are better able to absorb calcium from food than people who are not pregnant. The bodies ability to do so is even greater in the final few months of pregnancy, when the babies need for calcium is at its highest. 

Furthermore, estrogen is produced in higer amounts within a pregnant body, which serves to protect and maintain the health of the bones.

Additionally, the body can be seen to recover any damage to bone loss quite quickly after the birth of the child. The rate at which this happens may be slower if breastfeeding is taking place. 


These facts therefore support the notion that pregnancy can help to protect and improve the overall health of the bones!

Bone Benefits of Pregnancy


There is research to suggest that the more times a person has been pregnant, the greater their bone density will be. This is beneficial for long term health because it means that the chance of this person experiencing a bone fracture is decreased. This can also have an impact on how likely a person is to develop osteoporosis.


When osteoporosis strikes the bones begin to lose their strength and their density. Amongst other things, this means that they are at a greater risk of injury, such as breaks or fractures. Asides from the increased risk of injury, there are no other symptoms of this condition, meaning it can be difficult to know that you have it until you suffer a related injury.

Pregnancy During Adolescence


When a person gets pregnant before they have reached the end of their teenage years then they will be at an increased risk of pregnancy related bone loss. This can also put them at an increased risk of osteoporosis later in life.


This increased risk of osteoporosis is because they have not yet reached the peak of their bone mass development. Therefore, the babies bones may compete with the bones of the parent for calcium. This danger can be mitigated to some extent with an extra effort to consume ample amounts of calcium, both during pregnancy and when breastfeeding. 


The Impact of Breastfeeding


Experts state that the process of breastfeeding can cause between a 3 and 5% decrease in total bone mass. However,  the research also shows that this is not a permanent loss and can be regained once the child is no longer breastfeeding.


Breastfeeding Calcium Pregnancy Health


Approximately six months after breastfeeding finishes, the parent’s bone mass should have completely returned to normal. It is generally thought that this loss occurs because of the babies need for high levels of calcium during this time.


The length of time that breastfeeding goes on for varies from parent to parent, with some choosing to continue feeding their child in this way for several years.


Healthy Sources of Calcium


As the body requires greater amounts of calcium during pregnancy, it is essential to make an extra effort to include healthy foods that contain high levels of this mineral. The official recommendation for pregnant people is 1,000mg a day. However, in the case of pregnant teenagers this amount should be closer to 1,300mg.


Healthy sources of calcium include:


  • Green leafy vegetables
  • Tofu
  • Almonds
  • Low-fat dairy products
  • Fortified cereals

Exercise and Bone Health


Similarly to how your muscles grow during exercise, your bones too benefit from regular workouts. This is a concept that should be utilised during pregnancy in order to help keep the bones strong. Weight-bearing exercises are believed to be of the most benefit to the bones, but other types of exercise can also be effective and helpful. 


There is much evidence to suggest that exercising during pregnancy can help to reduce aching in the back, bloating, constipation and swelling. Exercise can also help to keep energy levels up, maintain muscle tone and strength, and promote a positive sleep cycle. Exercising during pregnancy can also make it easier to get back to full health and in shape post-pregnancy.
