This is another type of hormone that is important during the menopausal period. It still varies on the doctor s advice whether the patient still needs to have the progestin replacement. There are some women who make use of herbal treatments for treating their hormonal imbalance. However, most of the doctors still prescribe the use of conjugated estrogen because this is proven to be more effective. This is the necessity of having an appropriate level of Estrogen to prevent the unnecessary disorders that may take place inside a woman s body. Moreover, if the level of hormone is also imbalanced the risks of the menopausal symptoms will increase. It is true that Estrogen is a natural body substance but it is coupled with side effects in the person s body. Estrogen, as defined in the modern medical dictionary- does not only pertain to a single compound but is rather made up of groups of steroid compounds. While it is present in both male and female, it has higher concentrations in female, because it is the one responsible for the promoting of female secondary characteristics. However, if menstruation is noted, that is the time where estrogen is found in a higher level. This is normal because of the release of corpus letuem found inside the eggs cells during this stage. However, there are also moments that the production of estrogen is beyond normal. It can be a cause of some irregularities in the normal body function of some women. There is an increasing alarm that many of these affected women will not have a chance to be treated for estrogen deficiency. A correct management of estrogen deficiency should be taken into consideration since this deficiency can give permanent problems to the affected person. Two common lasting side effect of estrogen deficiency are osteoporosis and cardio vascular disease. For that matter, clinical practitioners were alarmed and advised their patients who use estrogen pills to protect their health. The users were even recommended to use a natural, bio-identical estrogen. A large number of women stopped taking estrogen pills after they have heard the initial report of the National Institute of Health that showed the serious danger of the estrogen pills.
