The Affect of Obesity on the Ability to Get Pregnant

over weightWhen attempting to get pregnant, many look at the considerations, their health, their lifestyles and decide if it’s the right time. Or it just happens.

But one thing that society is now experiencing, especially in the United States, is that obesity levels are on the rise, regardless of all the campaigns to reduce our weight.

According to the CDC, 39.8% of U.S. Adults in 2016 were considered obese and if looking at gender, between 36.5% and 44.7% (based on ages of 2039 and 40-59 respectively) of women were considered obese.[1]

That’s a lot of women who are looking at themselves and have to consider how being overweight could affect their ability to get pregnant.

So yes, while body positivity is abounding and bigger woman are on the rise, it still has to be taken into account that biggers isn’t always going to be better.

We have to take a hard look at the implications that being obese has on starting or growing a family.

It’s Preventable

If you really think about, unless there is something medically wrong that is causing weight gain, such as thyroid issues, medications, etc., then obesity, is one of the most preventable causes of infertility, and losing weight could reduce or negate the need for fertility treatments.[2]

So it’s a wonder why women don’t take that into consideration when they are trying to determine why they cannot have children.

While this may sound harsh, the reality is that as a society we have put less concern on our health as a whole when it comes to weight, and this is detrimental to women who are trying to grow their families.

The Science Behind It

When it comes to why obese women have a harder time getting pregnant, it’s because the higher levels of estrogen that is stored in their body due to excess fat, the reproductive system shuts down, which means no conception.[3]

Your body is a sensitive thing and the levels of hormones have to be relatively precise in order to conceive. When you are at a healthy weight, your body will produce the correct amount of estrogen in order to facilitate conception.[4]

But again, we will say that weight might not have been the first reason, the main problem. PCOS is a common cause of infertility and if you treat the PCOS, that could help with the weight issue thereby helping to conceive.[5]

PCOS also seems to be associated with insulin resistance, which, as you will see below, can cause an issue when it comes to fertility.

Another way that obesity affects your fertility is that your hormone imbalance can also lead to insulin resistance which can cause your body to not produce eggs correctly.[6]

This is also a risk factor for Type 2 diabetes[7] which is also something that either you don’t want to have to deal with, is generally preventable, and can make pregnancy higher risk.

Higher levels of insulin can cause metabolic changes that affect ovulation[8], which is essential for conceiving.

Another consideration for obese women is the consumption of vitamins and minerals in the diet.

The numbers look bleak with about forty percent of women are lacking the proper levels of iron, twenty-four percent are lacking in folic acid and four percent are lacking in B12[9], all of which are important before, during and after pregnancy. This could have a lot to do with a diet primarily consisting of processed foods.

Other Considerations

Other than the process of getting pregnant, there are certain indications if you do get pregnant that the pregnancy might not be as risk-free (although there are always risks regardless), as if one were at a healthy weight.

Being pregnant and obese can increase the risk of gestational diabetes, hypertension, miscarriage, and stillbirth and go into labor early.[10]

Those of which makes pregnancy not as enjoyable and more worrisome. So even if you do get pregnant, you’ll want to still consider your weight during those 9 months as well.

Finding your Healthy Weight

While you don’t have to be skinny in order to get pregnant, you should be at a healthy weight. That is different for everybody, literally.

While I may be 5’2″ and 125 pounds and be at a healthy weight, someone at the same height may be at a healthy weight at 115 or 135. It’s really dependent on the individual due to body structure and muscle.

Doctors still measure healthy weights with BMI, which is not exactly the most comprehensive way to determine health.

There are plenty of calculators online where you enter your height and weight and it determines your BMI. Consider though that your BMI is going to be a guideline.

So don’t look for a specific weight as a goal, which is why I’ll say the title of this is misleading, just find a range, aim for that, and make adjustments the closer you get. See how your clothes feel, how you feel, your energy levels, etc.

What Can You Do About it

First, don’t assume that your weight is the only thing that is preventing you from getting pregnant. As said before, it can be a combination of other issues.

You should first take a trip to the doctors, your self, and your partner as well because it can be either of you.

If you do find that that is the only thing that is preventing you from getting pregnant, then research has shown losing just 10 percent can increase your fertility.[11]

But you shouldn’t try and crash diets, do it slowly, do it the healthy way.

Another way to try and help you get pregnant, especially if you are still getting your periods regularly, is to track them with either an app or some other way.

When you track them you can determine how often you are ovulating as well and how regularly.

You should be having intercourse seven days before and after your ovulation starts, called your fertile period, but if you don’t have regular periods, then see your doctor.

And don’t give up hope. As your doctor first to make sure there is nothing else that could be causing the issue and then tackle the weight part.

Make it fun, don’t make it a chore. Workout with your husband or significant other and do something that you love to do. It’s not about going to the gym and running on the “treadmill” as some people call it.

Get out, enjoy the fresh air, make a meal plan and eats the foods on the outside of the stores (where the least processed items are).

Cook at home more. Just have fun with it and relax. It’s a change that anyone can make, and it might mean the difference between trying for a baby and having a baby. Good luck.
