Whether you are using shots or oral contraceptives, studies confirm a link to potential weight gain from taking additional hormones. This is the result of the kidney’s direct influence from estrogen levels.
Estrogen, a very powerful female hormone, stimulates a hormone system called renin-angiotensin. This is noted when an oral contraceptive contains greater than 20mcg of estrogen.
The newer contraceptives are effecting insulin resistance. This causes the body’s blood sugar to be less utilized during exercise and other activities. This insulin resistance allows blood sugar to be stored directly as fat.
The estrogen-based contraceptive is also an appetite stimulant for most women. Your body is always fighting off cravings, which also increase the body’s stress levels, resulting in higher levels of cortisol.
To prevent this from occurring it is recommended that you speak to your physician about using a contraceptive with less than 20 mcg of estrogen.
One option is to utilize an IUD, which may prevent weight loss and increase the chances of insulin resistance. Another option is to obtain oral contraceptives that are progesterone-based.
Studies show that a mixed contraceptive of estrogen and progesterone do not effect insulin resistance or appetite stimulation; however, side effects of this birth control can often be mood swings or physical changes just before menstruation each month.
Smoking and drinking alcohol often complicate the birth control issue with more side effects. All prescriptions should be discussed with your physician and your pharmacist.Resource: OnFitness Magazine
