The effectiveness of your contraceptive pill will be reduced if you are overweight- TRUE or FALSE?
Can you still rely on today's 'low dose' contraceptive pills or should you be swapping to a contraceptive pill that contains a higher dose of estrogen to give you adequate protection against getting pregnant? In one of the previous posts on my website about the contraceptive pill and weight gain I wrote, "Today’s oral contraceptive pills contain much lower doses of hormones than they used to so if you are overweight they could quickly become ‘burned’ up hence their effect in your body could be of a shorter duration and thereby increase your risk of becoming pregnant".In keeping you up to date on this issue, it seems that the latest studies are stating that overweight women are at a higher risk of getting pregnancy no matter which dosage of pill they take. Not very heartening if you're over 155lbs eh?
It is likely that you are using one of the new generation, 'low dose' contraceptive pills that are now regularly prescribed by most doctors because of the benefits of reduced side effects. I found this useful table on Dr. Rick Jelovski's site from a study which shows weight in relation to pregnancy rates for the different estrogen doses in the contraceptive pill. It may be handy to take it to the docs with you and see what comment he/she has about it all.
less than 125lbs --1.8 (20-25mcg )--3.2 (30-35mcg)--1.6 (50mcg =+)
125-137lbs-----------3.4 (20-25mcg )--2.7 (30-35mcg)--3.3 (50mcg =+)
138-155lbs-----------2.3 (20-25mcg )--2.0 (30-35mcg)--8.2 (50mcg =+)
155lbs and plus----6.8 (20-25mcg )--5.2 (30-35mcg)--5.4 (50mcg =+)
If you are over 155 lbs you are in the group with a higher tendency to get pregnant than women who weigh less than 125 lbs and you can see from the above table that if you stay at 155lbs lbs swapping to a higher estrogen dose contraceptive pill does not necessarily reduce your chance of getting pregnant so increasing your estrogen dose (and possibly accompanying side effects) is a step you might want to think a bit more about..
Yep, I know you won't want to hear it but the best way to reduce your risk of getting pregnant is to reduce a few kilos AND remember to take your pills consistently and correctly (the stats. in this table would have included women who were 'not perfect' at pill taking)
As Dr. Rick reminds us, the greatest risk from contraceptive pill failure is when you're LATE starting your pills again after the 7 day 'break', so if this has happened to you in the past, consider swapping to a continuous daily pill routine that will lower your risk and lower your stress.
Risk of Heart Attack
You have probably been told that you are at the biggest risk of having a heart attack if you are
overweight and you smoke, this is true but if you are also using hormonal contraceptives, you are
increasing your risk even more so while you're at the docs why not chat about some other safer options for birth control? It's a good idea to regularly check in with your doctor that the contraceptive pill you are using is the best one for your current circumstances- inspite of any extra pounds you may have gained.
