Birth Control Pills Make Women Gain Weight
Many women who are taking birth control pills are very happy to avoid unintended pregnancy but are blaming oral
contraceptives for weight gain and fluid retention at the same time. Well, it is the undeniable fact that pills do
cause weight problems in some women but not necessarily be the prime cause for all women.
The recent studies taken on low-dose (low estrogen) pills have indicated the nominal change. Additional few pounds
while taking pills could be possible in few but not necessarily be at alarming situation. Analysts have pointed out
that 5-10% women adding few pounds while they are taking pills but there is similar number of women who are gaining
weight but not on pills at all. Weight gain could be due to fluid retention in the body (occurs other than the
pills) and fat deposition.
How much weight gain could be possible on birth control pills?
It is usually argued that oral contraceptives, specially higher dose of estrogen pills (more than 30 mcgm), cause
more weight than birth control injection like Depo Provera. Studies have revealed that women using high dose pills
tend to gain 5.3 lb in a year compared to women who are taking Depo Provera as contraception and gaining 6.6 lb (2.2
kg) in a year's time. However, analysts have further found that only 7% women who were taking pills got more than
10% of they body weight. But women who were taking shots for Depo Provera, 25% of them gained more than 10% of their
body weight. If you compare 5.3 lb weight due to pills with 6.6 lb weight gained due to birth control injection, you
will notice that not only women who are on birth control pills get lesser weight in a year than birth control
injection method but also at lesser risk of weight gain.
Moreover, most of the recent studies on lower estrogen hormone based pills (30 mcgm or less) have shown weight loss
or no change, if continued to take for a year.
But birth control pills may cause fluid retention, isn't it true?
It can not be denied that pills containing high doses of estrogen may cause fluid retention in the body, specially
if the pill has 50 mcgm estrogen or more. How it happens? Well, high doses of estrogen stimulate kidney-substances
like renin-angiotensin, which is responsible for water retention that again causes sodium (salt) retention that
ultimately causes the weight gain. Studies on different levels of estrogen based pills revealed that pills having
less than 20 mcgm estrogen reduce weight, 30 mcgm pills make no difference in the weight or nominal loss of weight
whereas 50 mcgm pills cause fluid retention and weight gain.
If you are on birth control pill and experiencing more than 5% of your body weight gain in a year, it may be due to
your body's reaction to insulin resistance or abnormal glucose metabolism. You need to consult your healthcare
professional to adopt low carbohydrate diet because high amount of sugar in any meal will offset your weight control
Besides, low estrogen, what other types of birth control pills can affect on weight? The combined pills containing
desogestrel type of progestin and low dose of estrogen would cause very little weight gain compared to the pills
containing norethindrone (like Ortho Novum 7/7/7®). This is possibly due to specific progestin mainly due to lesser
insulin resistance. Low estrogen can be found in the birth control pills like Alesse, Loestrin Fe, Mircette etc. If
you are experiencing weight gain or fluid retention symptoms from your present oral contraceptives, you can consult
your healthcare professional or doctor to know which birth control pills are suitable for you.
