pressure
|
|
If you are taking birth control pills your blood pressure can
go high.
In reproductive age 15-45, many women have normal blood
pressure i.e 120/80, as estrogen and progesterone, femal sex hormones have some protetive
effects these hormones save females from cardiovascular problems. However as women attain
menopause, the protective effects of the female hormones dwindles away exposing them to a
variety of health risks.

pills have saved many women from undesirable pregnancies. These pills are hormone based and several

Are birth control pills and high blood pressure related?
|
|
Birth control pills or oral contraceptives contain
synthetically produced estrogen and progesterone. Some contraceptive pills only have
progesterone. Those pills which have both estrogen and progesterone are more prone to cause high
blood pressure – but only in some women. Other women take contraceptive pills for years and have
no problems with these pills. Studies show that estrogen component of the combined pills is
mainly responsible for high blood pressure although a few studies conducted by the National
Institute of Health have shown that progesterone birth control pills i.e mini pills, are likely
to cause a small increase in diastolic pressure so increasing risk of stroke and heart attack in
women.
Risk of high blood pressure in females taking
contraceptives depends on following factors.
• Age at which oral contraceptives are started: If you are starting taking contraceptives at or
above 35 years then you will have more chances of developing hypertension.Hence, such women need to
check their pressure before starting therapy and monitor it regularly till pill use is
stopped.
• Past history: In women already having blood pressure
related problems, the risk is again high and hence a thorough medical examination is very
important before the start of therapy.
• History of smoking: If you are a chronic smoker and are
also using contraceptives, then most probably you will have problem of high blood pressure
too.
If you have diabetes and you are taking contraceptives as
well, then you may develop hypertension as well with time.
How women taking birth control pills can tackle the
situation in the presence of the above risk factors:
• If you are above 35 years then you must get themselves
thoroughly examined for present and past medical history and family history to assess if any
other additional risks are present or not. If the blood pressure examination is normal then
contraceptives can be begun. Regular follow up with your consultant or health care provider is
necessary so that high blood pressure can be picked up.
• Positive history of blood pressure: In women who already
have high blood pressure before the age of 35 years or have recent past history of blood
pressure it’s probably good not to use pills. Other options for birth control would be a better
choice in these cases.
• For Smokers: Smoking causes damage to the walls of the
arteries and narrows their lumen by enhancing process of atherosclerosis and thus increases the
blood pressure. Contraceptives can have a similar effect by causing fluid retention and thereby
will augment the problem. The best thing to do is stop smoking.
If you have diabetes and also taking pills, then you should
not only control your diabetes under normal levels but also regularly check your blood
pressure.
For all women taking pills for birth control, it is essential
that they have a regular follow up with their doctor for a complete physical examination to look
for any changes in blood pressure and other things induced by the long term use of
contraceptives like weight gain etc.
