Among the birth control pills list, the three most common types are: the ‘progestin-only pills’, also known as the POP or the ‘mini-pill’; the ‘combination pills’ because they contain both estrogen and progestin; and the ‘emergency contraceptive pills’, which are basically to prevent pregnancy following unprotected sex. The emergency pill has been suggested not to be used as a regular contraceptive. These emergency pills are also referred to as ‘morning after’ pills.

The progestin-only pills (POP) are safe for women who are breastfeeding and women who are above age 35 and smoke. The pill works by thickening the cervical mucus and preventing sperm from entering the uterus and must be taken at the scheduled time each day. Nevertheless, they are not as effective as combination pills. In the birth control pills list, the combination pills are the actual ‘BCPs’ embodied by oral contraception. In this category, there are three types:

1.)    Monophasic pills – packets containing 21 pills of estrogen and progestin plus 7 of plain placebos. Common problems are it effects the menstrual cycle to once every three months.

2.)     Multiphasic pills – these contain varied amounts of hormones, taken throughout the schedule and have a reduced ratio of side effects.

3.)    Continuous use pill – known as multiphasic pills, contains a total of 28 pills. Common problem is that it prevents menstruation all together.
The emergency contraceptive pills (ECP) are meant for an emergency situation only. The two-dose regimen requires the first dose taken within 72 hours of unprotected sex, and the second dose within 12 hours.

Several factors may raise the possibilities of developing osteoporosis. Here are a few major factors:

Sex. This may sound like God’s bias, but the truth is- your being male or female has a lot to do with osteoporosis risks. Compared to average men, women are twice as much vulnerable to osteoporosis fractures. According to medical science, this is because women have lesser bone mass and usually live longer compared to men. Abrupt decrease of estrogen (that remains at menopause) is another factor accelerating women’s bone decay.

Age. Osteoporosis related risks tend to rise with age. This is because bones in human body get weaker with age.
Race. May sound odd again, but a study found that people with Southeast Asian origin are most vulnerable to osteoporosis risks. Compared to that, Black and Hispanic males or females are less exposed to osteoporosis hazards.
Family tree. Osteoporosis can run through families. So, you might be at higher risks when your parents or near blood connections have osteoporosis. This applies especially when your family has a legacy of fractures.
Body frame. Osteoporosis is a thing to worry for males or females with unusually thin bone structures or body frames. Technically speaking they are more prone to osteoporosis as they have lesser bone mass than usual. This gets worse as they age.
