Lo Loestrin Fe which is commonly called just Lo Loestrin is a birth control treatment for women. It`s made up of a small dose of the two bodily hormones, estrogen and progestin. These act in three specific ways to stop pregnancy, they halt ovulation, as well as changing the fluid on the cervix. Which is the narrow part at the top end of the vagina, this makes it harder for semen to actually get into the uterus. Also the lining of the uterus is altered by the pill, making it much more difficult for an embryo to attach to the lining of the uterus. Each pill only contains 10 micrograms of estrogen but is still able to provide fantastic protection against pregnancy. It also decreases the total number of bleeding days per month, to less than 4 on average, which is a distinct benefit. You`d have to be unlucky to concieve during the first year of use, as one clinical study that has been undertaken indicates that conception results in only about 3f women. It pays to follow the instructions for taking the pills carefully as this directly influences your chances of getting pregnant, in other words the more diligently you follow directions the less likely pregnancy becomes. Possible Side Effects Loestrin Side Effects It`s possible you may experience some unpleasant reactions to this birth control treatment, if you have any chest soreness, breathlessness or speech problems contact your doctor. In most cases these reactions are generally mild and it`s a simple matter to remedy. very few women who take Lo Loestrin Fe will have any problems. The reality is the majority of women have no problems at all. Based on the results of numerous studies, the most frequently described side effects include: * A feeling of sickness or vomiting. * Breakthrough blood loss or even spotting. * Monthly periods that are uncomfortable. * Changes in weight. * Breasts tenderness. * Facial Pimples. * Painfull stomach area. * Feeling anxious. * Becoming depressed. In each package of pills the first 24, coloured blue, contain both the estrogen and progestin hormones. In the subsequent two pills, coloured white, there is only estrogen. The final two brown coloured pills contain just iron, no active human hormones at all. The thinking behind this is that the iron will help prevent anemia which could result from blood loss throughout a woman's period. One might question the effectiveness of only getting iron capsules for two days a month, but I guess the fact that Lo Loestrin Fe provides some iron for the individual is better than getting none at all. This Health Warning applies if you are older than 35 and smoke do not use Lo Loestrin Fe. This is because the side effects associated with its use are increased by smoking cigarettes and increased age. These include stroke, blood clots and heart attack, which can all be fatal.
