Worried that being on the pill could cause you to gain some extra kilos? This guide explains why you should take a chill pill.
Birth control pills can be a blessing, saving you from clocking your ovulation window, scrambling for last-minute condoms and worrying over heat-of-the-moment oopsies. But they can also come with their fair share of psychological baggage. If you’re more er, cherubic than you were before you started birth control pills, it’s natural to wonder whether your contraception has anything to do with your weight gain. While it’s possible, it’s more likely that your unwanted kilos are souvenirs from all those late night dinners and overindulgent Sunday brunches you may have conveniently forgotten about.
Birth control pills are oral contraceptives that work by tricking the body into believing it is already pregnant. Pills release a profusion of estrogen into the body, mimicking the estrogen mechanism during pregnancy. In turn, the excess oestrogen triggers the production of a compound known as renin-angiotensin in the kidneys, which stimulates water retention. Usually, the degree of water retention is directly proportional to the quantity of oestrogen in the pill.
Multiple studies have shown no direct connection between birth control pills and weight gain. However, there are some birth control-related factors associated with weight gain.
While some women do put on a little weight as a result of starting birth control pills, this is usually due to fluid retention, with the extra kilos on the weighing scale disappearing within two to three months.
There is another reason that may equally cause you to pile on the kilos – a curiously increased appetite. If you find yourself indulging in second and third helpings, it may have something to do with your birth control pills serving as appetite stimulators. If you’re nodding in silent resignation, seek comfort in knowing that you can still keep your weight in check by making smart diet choices. Replace the second helping of rice with a hearty portion of salad, or another slice of pizza with a nice warm serving of soup. In general, appetite stimulation is more common in women with abnormal glucose metabolism.
Birth control pills can sometimes increase insulin levels, resulting in impaired processing of sugary and starchy foods. The result? Inordinate weight gain.
If you are one of the rare few that notices a weight increase due to birth control pills, voice your concerns to your doctor. You may be able to put an end to your weighty problems by taking a different type of birth control pill. You see, not every pill is made the same way. While some contain estrogen and progestin, others are completely progestin. And while estrogen itself is usually of the same type across pills, progestin comes in varying types, causing a variety of side effects. Remember, it’s important to give your body time to adjust to birth control pills. Observe your symptoms for at least three months before meeting your doctor.
If you’ve always looked at birth control pills as extra baggage – literally – it’s worth discussing with your doctor about the pill best suited for you. With the right pill, you can save yourself from stress and surprises, and keep your weight from tipping over the edge.

Multiple studies show no direct connection between birth control pills and weight gain. Some women may experience temporary weight gain due to water retention, which may disappear within 2-3 months, increased appetite from appetite stimulation, or increased insulin levels affecting sugar/starch processing. Most weight gain is from lifestyle factors.
Regular birth control pills contain estrogen and progestin. These may cause temporary water retention or increased appetite, but studies show no direct connection to permanent weight gain. i-Pill is an emergency contraceptive containing the levonorgestrel hormone. It has not documented any significant or long-term weight gain, though temporary weight gain, like fluid retention or bloating, is possible.
Yes, but rarely and usually temporarily. Birth control pills can cause water retention (disappears in 2-3 months), increased appetite leading to overeating, or increased insulin levels affecting food processing. However, multiple studies show no direct connection between pills and weight gain. Most weight gain results from dietary choices and lifestyle factors.
Discuss concerns with your doctor, and they can suggest the right pill for you. Different pills contain varying types of progestin, causing other side effects, while some are completely progestin-only. With the right pill suited for you, you can avoid weight issues. Give your body 3 months to adjust before changing pills.
